Are Reusable Freezer Bags An Eco-Friendly Answer?

Everyone’s heard about the damage single-use plastic products are causing. But just in case you haven’t, here’s a quick rundown. Single-use plastic doesn’t biodegrade, and even when it does start to break down, it can still be extremely harmful.

Microplastics come from partially degraded plastic products, and it can be extremely harmful to both humans and animals. You see, microplastic can leach into the soil, which then pollutes any food that grows in the area. Worst of all, after heavy rain, the microplastic is picked up and washed into natural water sources.

And this is where the problem starts for animals; they mistake the plastic for food, which kills them slowly after digestion. The old phrase “You are what you eat” always comes to mind.

You see, because microplastics infect the food we eat, you are too. This is causing a lot more harm to the human body then ‘they’ would have you believe; here are a few of the side effects caused by plastic:

  • Genotoxicity
  • Chronic inflammation
  • Cancer
  • Auto-immune conditions
  • Diabetes
  • Rheumatoid Arthritis
  • The list goes on

Luckily, people are starting to realize the harm single-use products are having on the planet. Even shops have started charging for plastic bags or stopped providing them full stop.

With one single-use enemy down, it’s time to begin the search for others. And is there any better place to begin than another plastic product, the freezer bag?

Are Reusable Food Storage Bags Safe To Freeze?

Yes, reusable freezer bags are perfectly safe to use in the freezer. The reason for this is freezer bags are made with either Silicone or PEVA. These materials can withstand extremely cold temperatures, with some going as low as -51°f. In other words, these materials cannot freeze. Both materials are also food safe, which is necessary if you want to decrease your chemical intake.

Silicone freezer bags tend to be the favorite for most consumers for a few reasons:

  1. More Durable – Silicone is far more durable than PEVA, which means the bags will last longer without splitting.
  2. Withstands Heat – Many PEVA products cannot withstand high temperatures, which means you can’t deforest stuff in the microwave.
  3. Higher Food-Grade – A great benefit of using silicone bags is they can have a higher food grade, which means fewer chemicals are used.

In the end, whichever material you choose, you can rest assured knowing it’s safe to be storing your food in.

Recommended Brands

There’s plenty of freezer bags on the market for you to have a dabble with. The problem is, some of them don’t perform as well as others.

This is why this segment is devoted to bringing you the very best reusable freezer bags. So, without any more delay, let’s take a glance at the best freezer bags the market has to offer:

WOHOME Silicone Bags

As mentioned earlier, the freezer bags are made with silicone and come in a pack of six airtight bags. The bags come in four different colors, which helps you identify what you need from a packed freezer.

Because the bags are made with silicone, the bags can withstand extreme heat as well as the freezer. This gives you a few more options when it comes to cooking with the bags.

To seal the bags, they use a zipper system which ensures the freshness is locked into the bag every time. Another nice touch is having measurement markings on the outside; it makes it a lot easier to position your food.

Inspriratek PEVA Bags

They come in a set of six bags, and as a bonus, they also include two stainless steel straws to help you further reduce the amount of plastic you use.

eco-friendly-freezer-bags

Because the bags are made with 100% PEVA, you don’t have to worry about any dangerous compounds such as BPA or Chloride. This makes it a healthy and more environmentally friendly option to PVC bags.

Each freezer bag uses a double-slide zipper which ensures they stay completely leak-proof and lightweight. With the zipper closed, you can store up to one litre of food without any escaping or the bag breaking.

Ecomore PEVA Bags

With these freezer bags, you get seven in the pack, with each one holding one gallon of food, which is more than enough. They can be used to store meats, vegetables, and much more in the freezer or fridge.

The tight seal of which is provided by the zippers ensures your food doesn’t get any freezer burns and stays fresh at all times. They claim that each bag can replace other 350+ disposable plastic bags.

The PEVA is completely food-grade, so you don’t need to worry about any substances leaching into your food. One thing to mention is, these freezer bags do not perform well under high heat so you should avoid using them in the microwave.

Rounding Up

Single-use plastic products are extremely bad for the environment, which is why reusable freezer bags can be so beneficial.

You have to remember, plastic products don’t break down in the same way as natural materials, which is causing a nightmare for the trash system.

And it’s not just because they don’t biodegrade; it’s also because of the quantity that gets used. This is why using reusable items like these freezer bags can be very beneficial.

It can significantly reduce the amount of plastic you use in your household. And this can only be a benefit. Remember, single-use plastic is killing animals at an alarming rate and poisoning human food. Using reusable freezer bags can help to further eliminate this problem.

The Environmental Impacts of Agricultural Modernization

Farming is a vital industry that is constantly changing to improve crop yields while minimizing the impact on the environment. The seven billion people on the planet need to eat, and the farms around the globe need to provide food while still being stewards of the land.

Environmental Impacts of Agricultural Modernization

Worries About Continued Environmental Damage

Innovative farming techniques continue to consider the environment, especially as the population grows. With many areas of the world being affected by global climate change, farmers need to learn how to accelerate their productivity.

Unfortunately, farming techniques have harmed the environment. Farmers need new techniques that protect the land and deliver respectable crop yields. Farming communities should evaluate their water usage, grazing land, and fertilizer choices to begin to reverse the damage done through the generations.

Making changes to environmental practices in the farming industry can help reduce climate change anxiety. With so much talk about rising sea levels and increased forest fires, people living with anxiety often worry about how farms will feed everyone on the planet. When farmers help take care of the planet, anxiety levels can drop.

Taking Care of Farmers

People who work on farms need to take care of themselves. Farming is hard work, so farmers should use stretches for sciatica to keep their backs and legs strong and flexible. Workers with healthy bodies have the peace of mind to develop solutions to protect the land from environmental damage.

compost-organic-waste-farming

The concept of safe food using organic waste generated compost is getting traction.

Farmers also need to take care of their physical and mental health. Unfortunately, too many farmers suffer from depression and other mental health issues. Sadly, they don’t reach out for help because mental health problems have a stigma in many farming communities.

If the people of the world expect farmers to make innovative changes to their techniques to protect the environment and feed the world, farmers must get the health care they need. It’s challenging to do a hard job when your body and mind are suffering.

Using Fertilizers Wisely

With synthetic fertilizers, farmers can increase the speed of their crop production. Modern farming communities have used synthetic fertilizers for generations, but these fertilizers have put too much nitrogen into farm fields. While this isn’t problematic for grains like corn, wheat, and rice, it is for other foods.

liquid fertilizer

The excessive levels of nitrogen in the soil don’t stay there. Unfortunately, the nitrogen washes into waterways and gets into the air. The nitrogen harms aquatic ecosystems and can cause toxic algae blooms that destroy the organic matter that feeds fish, animals, and people. Eventually, the waterways become dead zones, and nothing grows in them.

Because China manufactures and uses nitrogen-based synthetic fertilizers, many waterways are polluted and no longer provide fish and plants as they once did. The Gulf of Mexico has several dead zones from toxic algae blooms due to nitrogen fertilizer. These synthetic fertilizers release nitrous oxide, a dangerous greenhouse gas, into the atmosphere. People, animals, and plants cannot thrive when too much nitrous oxide is in the atmosphere.

To improve the environment, farmers need to look for alternative fertilizers that do not damage ecosystems. Fertilizers need to improve the efficiency of crop yields without hurting other food sources.

Improving Irrigation Efficiency

Along with fertilizers, farms need fresh water. The majority of freshwater on the plant goes to the agriculture industry, and farmers use a plethora of techniques to get water and feed their plants. Sadly, many parts of the world have freshwater sources, making it more challenging for farmers to effectively feed their crops.

Diverting so much freshwater to farms is environmentally and economically taxing. Moving water can wreak havoc on the environment by creating areas that become oversaturated and other areas that dry out. Irrigation practices can also affect the weather, as evaporation from groundwater and irrigation channels becomes precipitation.

Irrigation practices can empty aquifers. It can also change coastlines and ecosystems. Farmers need to develop innovative methods to reduce the water needed to irrigate plants properly. They also need to consider the water they use to keep their animals hydrated. Water is a necessary commodity, but one that needs better regulation to protect the resource.

Conclusion

Farmers and stakeholders need to develop innovative techniques that protect the environment from damage from agricultural modernization.

Synthetic fertilizer negatively affects fresh and saltwater around the world. Farms need irrigation, but they need to change how they get water and use it. Without changes, the farming industry will suffer from irreversible damage from neglective practices and climate change.

Proactive Prevention of Common Hazardous Waste Violations

In 2019, the EPA levied fines totaling  $170,000 against three Southern California-based companies, namely, Coat Product, Inc., International Aerospace Coatings, Inc., and Goodwest Rubber Linings, Inc. These companies allegedly violated the federal Resource Conservation Recovery Act (RCRA) that oversees the proper management of hazardous waste.

Hazardous waste regulations compliance is complex, and businesses of all sizes find them significantly stringent to follow and comply with. If found guilty, the organizations are liable to pay huge fines that can financially wipe out small and mid-size organizations. This article can help businesses stay proactive about preventing hazardous waste violations.

Types of Hazardous Waste

Hazardous waste is any solid waste that is listed as a known hazardous waste or exhibits any characteristic among ignitability, corrosivity, reactivity, or toxicity. A known hazardous waste is categorized into four lists named F, K, P, and U lists.

 The hazardous waste regulations differ based on the quantity of waste generated by your business.

  • Large Quantity Generators – Businesses that monthly generate more than 1000 kg of hazardous waste or more than 100 kg of acute spill residue or soil, or more than 1 kg of acute hazardous waste.
  • Small Quantity Generators – Businesses that monthly generate hazardous waste between 100 kg and 1000 kg.
  • Very Small Quantity Generators – Businesses that monthly generate up to 100 kg of hazardous waste, or up to 100 kg of acute spill residue or soil, or up to 1 kg of acute hazardous waste.

After knowing your class of hazardous waste generators, let’s understand some of the common hazardous waste violations.

Common Hazardous Waste Violations

1. Lack of Proper Labelling

Proper labeling is critical for notifying government waste haulers, safety personnel, and your employees regarding the accumulated chemical, specifically in the event of an emergency and how long it has been accumulating onsite.

2. Improper Disposal

Businesses dispose of hazardous waste by illegally dumping it due to various reasons, including lack of time and efforts, avoid disposal fees, lack of knowledge about what constitutes hazardous waste, or understaffed or untrained workforce with lack of waste management procedures knowledge.

3. Improper or No Determination of the Waste

Many times, the generators fail to properly determine the waste by testing it or knowing its stream that can attract hefty fines.

4. Improper Management of Expired Waste

Expired chemicals can be extremely volatile and considered hazardous waste. These materials can be dangerous as they are no longer in their original containers and can become less stable or have decomposed due to aging. They are subject to hazardous waste generator requirements as well as the regulatory timeframes in which they can be disposed of or stored.

5. No or Inadequate Waste Manifests

Adequate paperwork is also critical when it comes to hazardous waste. After storing and labeling hazardous waste, you, as a generator, are mandated to complete the Hazardous Waste Manifest that outlines the type and quality of waste. Further, you need to mail its copy to the appropriate regulatory agencies such as EPA and DOT (Department of Transportation).

6. No or Inadequate Training for Employees

Inadequate employee training can lead to improper hazardous waste handling procedures that might result in treacherous spills, toxic chemical reactions, and spreading fire. Also, failing to wear protective gear can expose your employees to radioactive materials, fumes, and other hidden risks that can cost their lives. Not following proper updated standards for employee communication and training can result in hefty fines.

7. Lack of Contingency Plan

A generator should have a written Hazardous Waste Contingency Plan that can be implemented immediately during an emergency, including explosions, fires, and sudden unplanned release of hazardous waste. It’s designed to minimize hazards to the environment and human health during emergencies. Failing to have a contingency plan can result in significant fines.

8. Improper Management of Mercury

Mercury and its products are incredibly toxic and can cause chronic and acute poisoning and severe illness if mishandled. Improper management of mercury attracts hefty fines as it can lead to spills and evaporation, risking human lives and the environment.

9. Open Containers

Not closing the containers containing hazardous waste is among the common violations and can be a cause of accidents and physical injuries that can be avoided with a few precautions.

10. No or Infrequent Weekly Inspections

All hazardous waste generators are compelled to perform a weekly inspection of their hazardous waste container storage areas. It’s also a common violation that can be easily avoided by the implementation of standard procedures and compliance maintenance.

How to Prevent Hazardous Waste Violations

Hazardous waste violations and the associated hefty fines can be avoided by implementing standard procedures and giving due diligence during generating, storing, transporting, and disposing of hazardous waste.

  • Follow rigorous labeling of containers with hazardous waste including name and address of your facility, accumulation start date, source or identity of waste, characteristic of waste, mentioning what makes it hazardous, and physical state of the waste.
  • Keep in mind proper licensing and know your waste generator requirements.
  • Understand the “cradle to grave” requirements by RCRA.
  • Comply with hazardous waste management training requirements by providing on-the-job as well as classroom training to your employees on hazardous waste management, storage, and disposal procedures.
  • Contract with a reputed and properly licensed hazardous waste company that will provide proof of proper disposal along with adequate documentation. Closed top mini frac tanks can be ideal for hazardous waste disposal as they ensure safe transportation of chemicals and other volatile substances.
  • Properly determine your waste streams with the Hazardous Waste Identification process.
    • Check if it is solid waste.
    • Check if it’s particularly excluded from RCRA.
    • Check if it’s listed as hazardous waste.
    • Check if it exhibits hazardous waste characteristics.
  • Conduct regular audits. Keep track of expired chemicals to dispose of them properly. Have a centralized purchasing and inventory process for effective organization and inventory management of chemicals.
  • Fill out and double-check the Uniform Hazardous Waste Manifest correctly.
  • Create an adequate contingency plan based on your company’s waste generator status. The plan should include contact information of emergency coordinator, emergency equipment location, emergency phone numbers, and more.
  • Conduct regular audits and weekly inspections of the storage area and containers and keep them closed at all times. Maintain a log record. Ensure that the storage area is free from debris and other materials, container tops are free from spillage, containers are in good condition and free from spills and leaks, and the ground is clean and dry. Make sure that the waste is stored in compatible containers.

Stay in the Know About EPA Regulations

Besides knowing the common hazardous waste violations and how to avoid them, here are some of the critical EPA laws and regulations you should know if you are dealing with hazardous waste.

  • Resource Conservation Recovery Act (RCRA) – The act is aimed to protect human health and the environment from waste disposal hazards.
  • Clean Air Act (CAA) – Its goal is to enhance and protect the country’s air quality.
  • Clean Water Act (CWA) – It intends to prevent, reduce, and eliminate pollution in groundwater and navigable waters.
  • Toxic Substance Control Act (TCSA) – It aims to protect human health and the environment from potentially hazardous chemicals by restricting their manufacture, processing, and use.

Hazardous waste violations are taken extremely seriously, and the associated fines can spell financial doom for small and mid-sized companies. However, well-thought procedures, a disciplined, proactive approach, and routine inspections can help you stay compliant.

Air Pollution and its Invisible Danger – What You Need to Know

If you’ve been observing the ongoing and high-profile protests from Extinction Rebellion over the course of the last few years, you’ll be aware that air pollution offers a significant threat to the human population.

This is supported by the statistics, which have revealed that almost a quarter of the people in the UK have been exposed to dangerous levels of air pollution with potentially devastating health consequences.

More specifically, a study by the British Heart Foundation (BHF) found that about 15 million in the UK live in areas where the average levels of the toxic particle PM2.5 exceeds the World Health Foundation’s guidelines. But what do you need to know about this invisible danger?

air-pollution-repurcussions

What is Air Pollution and How is it Caused?

In simple terms, air pollution is defined as the presence of substances in the natural atmosphere that may be harmful to the health of humans and other living beings.

Air pollution may also cause long standing damage to the climate or individual materials, while there are different types of air pollutants including particulates, gases and biological molecules.

Historically, the history of air pollution can be traced back to the Industrial Revolution, as developed nations such as the UK began to leverage fossil fuels such as coal to drive economic growth and expansion.

As a result of this, large and industrialised nations have produced high levels of smoke and sulphur dioxide for a range of domestic and industrial purposes, creating an omni-present threat to clean air and one that has worsened incrementally over time.

Substances such as nitrogen oxide are also impactful in this regard, with this produced from the reaction of nitrogen and oxygen in their air during combustion.

The threat of this has become increasingly prominent in highly congested areas packed with high motor vehicle traffic, creating a huge and growing pollution challenge.

Health Impact of Pollution and the Reaction of Governments

According to the WHO, air pollution contributes to an estimated 4.2 million premature deaths globally, with conditions such as heart disease, stroke, acute respiratory infections and lung cancer.

Interestingly, worldwide ambient air pollution accounts for 29% of all deaths and disease that involve lung cancer, along with 25% of similar cases related to ischaemic heart disease.

Incredibly, air pollution also contributes to 43% of all deaths and diseases that arise from chronic obstructive pulmonary disease, which causes significant breathing difficulties and long-term inflammation within the lungs.

china-air-pollution

Fortunately, countries across the globe are beginning to take steps to tackle air pollution, even serial offenders like China. Here, the government is taking direct action to clean up smog-choked skies from years of relentless industrial expansion, primarily by investing $83.4 billion in the renewable energy sector in 2019.

Nations like China are also drawing on innovation and technological advancement, with firms such as ERG Air Pollution Control providing various tools and measures to help tackle air pollution directly.

This includes everything from industrial gas cleaning services to comprehensive air pollution control systems, which help to mitigate the worst impacts of climate change without compromising on economic growth.

How to Reduce Your Digital Carbon Footprint?

Roughly 2.5 billion people around the globe use the internet. Experts predict the energy used to power the internet — as well as the number of greenhouse gases produced — will soon exceed air travel. Your digital carbon footprint is comprised of a number of activities, not just checking email.

Digital activities that have an impact on the environment include:

  • Streaming music
  • Watching Netflix
  • Posting on Twitter
  • Buying an e-book
  • Reading online news

Today’s eco-conscious consumers and businesses are looking for ways to reduce their digital carbon footprints and implement sustainable practices.

1. Reach Out to Tech Companies

Tech companies like YouTube can reduce their digital carbon footprint by changing how their design. In 2016, people streamed about 1 billion hours of YouTube videos each day, producing 10 million metric tons of carbon dioxide equivalent (CO2e) — the same as the City of Glasgow.

For users who only listen to YouTube for the audio, the option to turn off the video could save 100 to 500 Kilotons of CO2e each year — comparable to the carbon footprint of 30,000 homes in the U.K. For consumers, it’s imperative to reach out to your favorite brands and request eco-conscious features.

2. Unsubscribe from Unwanted Emails

In 2018, more than 281 billion emails were sent and received each day, a number that’s expected to grow to more than 347 billion by 2022. Like anyone else, you probably have multiple brands who send you unwanted emails. To reduce your carbon footprint, make use of the unsubscribe button.

Look through your inbox for any unwanted emails you’ve yet to delete. You should also go through your promotions and spam folder. The unsubscribe button is typically at the very bottom of the email. Some brands attempt to hide it by making the text a similar color as the background.

3. Optimize Your Charging Routine

How many digital devices do you charge? There’s the laptop, cellphone, tablet and smartwatch. To reduce your carbon footprint, optimize your charging routine. Once a device is fully charged, unplug the power supply. Not only can you reduce your energy consumption, but you’ll also improve the lifetime of your battery.

Reduce your reliance on fossil fuels by investing in a solar charger. There are many solar charging stations available that range in capability and price. You can find a quality set-up under $50 for a smartphone, tablet and watch. If you want to power heavy-duty devices like laptops and film equipment, you’ll want to research options $75 and above.

4. Hang Onto Your Old Device

In the U.S., 44% of smartphone users said they replace or upgrade their phone as often as their provider allows, typically every two years. Many of these working devices end up cluttering landfills, while others are broken down into usable materials. Consumers and businesses alike can reduce their digital footprint by holding onto devices longer.

If you have a cracked screen, look into DIY tools online, or visit a local shop. The cost is remarkably affordable compared to the latest phone model. If your device is running slow, delete unused or unwanted apps, photos, videos, files and more. Most smartphones have a built-in storage cleaner that can free up space.

5. Download Instead of Stream

Video streaming makes up a large chunk of internet traffic. Data centers that host streaming sites like Netflix, YouTube and Facebook consume around 1% of the world’s electricity each year, a number that’s expected to grow. More demand for this type of technology means more consumed energy.

To minimize carbon output, data centers need to be fed by renewable energy sources, such as solar, hydroelectric or nuclear power. As a consumer, you can reduce the amount of time you spend streaming videos and music each day. Try to download content ahead of time, which puts less strain on networks. If you do stream video, connect to Wi-Fi instead of 4G to consume less energy.

Most of the resources we rely on are finite. It’s crucial to make sustainable choices and reduce your carbon footprint. Reach out to your favorite tech companies and request eco-friendly alternatives. Pare down your inbox and delete any offers for a phone upgrade. You can also invest in a solar charger and reduce your streaming time.

For most of us, it’s impossible to cut out internet use entirely. However, it’s still possible to make eco-friendly decisions.

3 Ways Zero Valent Iron Can Help in Environment Protection

Zero Valent Iron (ZVI) was developed to eliminate chlorinated hydrocarbon solvents in the soil. Industrial solvents are replete with chlorinated hydrocarbon, so much toxic and bad for the environment. They get disposed in the soil along with other toxic elements to cause harm to our surrounding. In the current years, significant improvements have taken place in the realm of iron-based technology.

Zero Valent Iron can be effectively used in soil remediation

The result of years of research and significant improvement in the iron-based technology is the advent of nanoscale or polymer-supported iron-containing nanoparticles to remove contaminants from solvents and soil. This is all due to the high surface area to the volume ratio of such nanoscale particles that favor the reaction kinetics and sorption.

But, know one thing that high pressure drops may restrict fixed-bed column application. This is why we now have modified nanosized ferrous particles to facilitate arsenic removal. The fabulous reducing agent helps in pollution recovery, and thus it benefits our environment.

Applications of Zero Valent Iron

ZVI in recent times is used widely for wastewater treatment, groundwater, and soil treatment. If made through the physico-chemical process in combination, the ZVI may be very small particles, having a large surface area. ZVI is beneficial for the environment, for it has a strong reductibility, great purity, long aging property, and similar features.

Zerovalent Iron can boost the chlorine removal efficiency of the soil, groundwater, and six valent chromium. Thus, it reduces the time required for environmental remediation. Acting as a fabulous reducing agent, it facilitates pollution recovery. Indeed, you may also combine it to bioremediation to further improve the efficacy of environment pollution recovery. Use it in the soil, solvents and industrial wastewater confidently to get rid of the contaminants. The use of ZVI paves the way for pure water and soil.

What you should look for in ZVI?

Are you planning to procure zero valent elemental metallic ions for wastewater treatment or soil remediation? Zerovalent metals or ZVI has a wide range of applications that range from electrodes and trenches to filters. Yes! It helps in the water filtration process, and thus we have pure drinking water. It gets rid of every trace of impurity or contaminant from the solvent or soil. It is important to look for a reliable company to procure ZVI.

Watch out for the following properties of ZVI

  • The particles must be fine enough to be customized as per your application
  • Look for the great adsorption performance and sound chemical activity
  • A large surface area for that very strong reductibility
  • Make sure the duration of its effect is very long to reduce the injections
  • Very fine ZVI particles to remediate pollution and to save remediation time and effort
  • Must be environment-friendly, deprived of any toxic compound

Enhanced nitrate-removing potential

Zero-valent metal has an enhanced nitrate removal capacity. It eliminates nitrate from the groundwater to facilitate remediation. Hence, biochar-supported ZVI can facilitate nitrate removal while the ones with wider pH can remove larger nitrates. Biochar composite eliminates nitrate from the groundwater without leaving any harmful by-products. But, biochar has a variable nitrate-removal capacity.

ZVI biochar has a potential to reduce nitrate by mediating the redox potential, the electron transfer, pH and thus facilitates enhanced removal or reduction of nitrate from the solvent or soil. Everything revolves around the logic of intensifying chemical reduction in order to eliminate nitrate from the soil or groundwater.

Nitrate and How it Accumulates

Nitrate is the form of nitrogen, which lies beneath the cultivable land. Nitrate is water soluble and may move through the soil quite easily. Owing to its high mobility, it moves to the groundwater table. Once it has moved to the groundwater table, it persists there and deposits to a very high level.

Thus, shallow groundwater is also at a risk of contamination from chemicals of land surfaces. This is a matter of concern, and indeed, nitrate in water may harm human health, aquatic life, livestock life and contaminate the surface water. We can say that it is not that harmful to adult humans, but it can significantly affect the health of the infants. It may reduce the level of oxygen in the blood to cause ‘blue baby’ disorder.

Hence, biological denitrification, ion exchange, and reverse osmosis are the treatment processes to handle this issue. The use of ZVI is a way to denitrification and the key to attaining a safe nitrate level in the water. A zero-valent metallic reduction is an effective way to refine dirty and polluted water. As soon as ZVI is placed in the flowing water or is added to the flowing water, there starts the process of oxidizing. The resultant chain reaction will purify water or remove the contaminants.

A Tool to Remediate Acid Mine Drainage

AMD or Acid Mine Drainage is the most common source of metal in places like the Appalachians, Tennessee, and Kentucky. It is important to remediate acid mine drainage for it is highly acidic and toxic. It is the major contributor to the arsenic environment and something needs to be done. AMD is a rich source of heavy and corrosive metals, acidic in nature. Biological treatment of Acid Mine Drainage is cost-effective, efficient and environment-friendly.

Biotechnological processes are an asset when it comes to treating Acid Mine Drainage in an effective manner. ZVI is environmentally sustainable. When it is very complicated and difficult to treat or remediate Acid Mine Drainage, ZVI eases the process. It gets rid of harmful elements or potentially hazardous substances from AMD to separate metal from acid and toxic compounds. There isn’t a need to abandon a mine site just because there are acidic metal deposits. Mine metals can be reclaimed with ZVI, and herein lays the environmental benefit.

Recycling of metallurgical waste

It is important to treat AMD or Acid Mine Drainage. The ecological solution to separate toxic metals, to reclaim water in large quantities is gaining a lot of attention. ZVI and zero valent metals save our natural resources and prepare the toxic metals for the recycling process. This is only possible through the separation of the acidic part.

We can recycle gallons of water that lay in the pond and other water bodies. It drops the acid level in the water and metal while also prevents heavy metallic reactions. When Acid Mine Drainage is one of the serious concerns in the realm of coal mining, zero valent metals prevent any exposure of sulfur-rich mineral to the water and atmospheric oxygen.

Final Thoughts

Zero-valent metals can help in the treatment of contaminated zones through the process of remediation. Zero valent iron is the highly reactive powder for remediation of wastewater and soil and works fabulously on environmentally contaminated areas.

If you take a look at sector shortages in New Zealand, you’ll find that agriculture and farming is one of the sectors struggling the most. There are long term shortages in the industry, so what’s putting people off from investing in this type of career path?

Although agriculture has dwindled in popularity since technology took over, there are other factors contributing to its decline. In New Zealand, there are strong environmental protection laws in place which need to be followed.

Here, we’ll look at how the agriculture industry deals with environmental protection laws in New Zealand.

What do the environmental protection laws cover?

The environmental protection laws in New Zealand are some of the strictest in the world. The country has earned a reputation for its clean, beautiful landscapes. A lot of its tourism is driven by its cleanliness and thriving ecosystem. This means the government has needed to introduce strict environmental protection laws to ensure New Zealand retains its pristine reputation. These laws include:

  • Resource Management Act 1991
  • Conservation Act 1987
  • Environment Act 1986
  • Ozone Layer Protection Act 1996

These are just a small number of the regulations and laws pertaining to the environment. There’s also a large list of related laws in New Zealand, making it difficult for businesses to keep up. This is especially true for those working within agriculture and industrial sectors.

New Zealand’s rivers under serious threat

Although New Zealand has developed a reputation as one of the most environmentally friendly countries in the world, it’s rivers are currently under serious threat. The environment ministry claims that two-thirds of the country’s rivers are now deemed un-swimmable. Even more worrying is that three-quarters of all of the country’s freshwater native fish are under threat of extinction.

In a bid to tackle the problem, the government has announced a rather ambitious plan. They are aiming to see a noticeable improvement over five years. Freshwater protection plans are being drafted and are expected to be put into place by 2025. In the meantime, immediate interim controls have been introduced. Swimming pools will be subject to increased water quality standards. However, it’s the farming sector which is going to see the biggest changes in regulations.

How are the agricultural and industrial sector dealing with the laws?

The agricultural and industrial sectors are currently struggling with the change in legislation. Although the government has pledged $229 million NZD to help farmers transition to the new laws, there’s still a lot of challenges the sector needs to overcome.

Farmers need to stop risky farm practices, such as allowing cows to stray to nearby waterways. Cow manure is partially being blamed for the increase in river pollution. New irrigation practices will also be denied unless farmers can prove it won’t harm the environment. There’s a lot of new laws being introduced which are causing issues for farmers and the industrial sector. Those working within the sector would do well to seek advice from specialists such as RSM.

Overall, New Zealand is making its environmental protection laws stricter over the next five years. This is already having an impact on the agricultural sector. However, seeking professional advice can ensure those working within the sector understand and adhere to the new legislation.

11 Ways College Students Can Save Paper

Paper, in all of its forms, is one of the most useful and versatile products. It is also one of the most widely used item for college students. The bad news is that our use of paper has some pretty intense impacts on the environment. These include water and air pollution, deforestation, and the accumulation of paper waste in landfills.

The good news is that every individual can play a role in helping to eliminate the damage done by the use of and production of paper products. Now, this is the point where many readers will think of themselves, “I recycle. Isn’t that enough?”

The truth is, while recycling certainly helps, it doesn’t eliminate the problems our use of paper creates. In fact, the recycling process itself has an environmental cost.  Keep recycling for sure, but also consider ways in which you can reduce the amount of paper you use. Here are a few top ways college students can save paper:

1. Make your subscriptions digital

Whether your interests are in technology, fashion, current events, music or something else, magazines are full of useful information. The problem is that once you’re done with them, your choices are to recycle them, throw them out, or let them collect dust. None of these things are good for the environment.

Instead, convert your paper subscriptions to digital. Not only will you help the environment, you’ll save space as well. Even better, digital copies of magazines are searchable. This means you can find the articles you want with ease.

2. Donate old newspapers and magazines

If you do have hard copies of newspapers and magazines at home, don’t throw them out or recycle them. There may be places that are happy to take them off your hands. Your local community center, retirement homes, hospitals and homeless shelters are often in search of reading materials for their clients.

3. Use double-sided printing

There is no way to avoid printing altogether, but you may be able to reduce the paper you use when you do print. Whenever possible use double-sided printing. You can even print more than one page per side. Also, experiment line spacing and font size. With a few adjustments, you can significantly reduce the amount of paper you print over time. Encourage your friends, even your University and College, and your community to do the same.

4. Get your statements online

If you are still receiving your bank statements and billing notices via snail mail that’s a problem. Not only are you getting your paper bills and statements, chances are you’re receiving inserts, coupons, and other junk. Convert to paperless mode and eliminate all of this.

5. Use a blackboard or whiteboard

Shopping lists, reminders, and notes to your roommates represent just a few of the things you likely jot down and have scattered about your place. You aren’t alone. Those bits and pieces of paper add up. You can replace these by simply hanging up a whiteboard or blackboard in a convenient spot.

If somebody needs to jot something down, they can use that instead of wasting paper. If you need something a bit more portable, simply snap a picture with your phone.

6. Get a digital calendar

You also don’t need paper to stay on top of your schedule or to coordinate with friends and family members. Instead, choose a digital calendar that works for you. Then arrange to share calendars with those friends and family members. With most online calendars you can create to-do lists, set alarms, and send out reminders.

7. Give old newspapers to animal shelter

Your local animal shelter or rescue might be thrilled to get your old newspapers. They use these for bedding and as cage liners.  Newspapers can also be used to help insulate winter shelters for feral cat colonies.

8. Use washcloths and hand towels

There is no doubt that paper towels and napkins are useful. Many of us use them while we’re eating, to wipe up spills, for cleaning, even for covering food in the microwave. The problem is that once we’re done all of those paper products go directly into the trash. That’s wasteful and bad for the environment. Instead, invest in cloth alternatives.

Washcloths and hand towels are exceptionally cheap. Cloth diapers last forever and are amazing for cleaning. Even old worn-out clothing can be cut up and used as dust rags.

9. Take notes digitally

At this point, there should be little or no occasions where you need to take notes on paper. There are simply too many options for taking notes digitally, not to take advantage of this. Save paper by using an app, such as Evernote, to take and organize your notes. While applying for college admission, make use of admission essay by domyessay.

Use voice to text, or simply type up your notes in your favorite word processor. Not only will your digital notes save paper, you’ll be better able to create quality essays and research papers. If you need help to turn these notes into better papers, check out essay editing reviews. Save the planet, and improve your grades.

In some cases, you don’t need to take notes at all. See if your instructors save handouts and lecture notes online. Then, simply use these as reference materials.

10. Reduce paper use at the grocery store

Hopefully, you have ditched single-use plastic and paper bags for reusable ones. If not, this is a great place to start. However, that’s just the beginning. There are other ways to reduce paper use while you shop.

First, hit the bulk bins for your dried goods. Instead of using the plastic or paper bags provided, bring your own reusable containers. Next, pay attention to packaging as you shop. You’ll be amazed at the amount of paper and plastic that is wasted through extra packaging. Be a conscientious shopper, and buy products that use the least amount of paper material.

11. Praise brands that use less paper

While you shop, pay attention to which brands are responsible in their use of paper and which brands are not. Then, let your thoughts be known. If a brand is behaving responsibly in this area, contact them and let you know you appreciate it and will be buying their products.

If not, contact them with your concerns. Believe it or not, companies do care what you think, and if they hear from enough people they might change their behaviors.

Final thoughts 

Paper waste is a huge problem at colleges and universities. In fact, the issue can seem overwhelming. However, if every individual would change a few of their habits with regard to paper consumption, there would be a great impact. You can get started with these steps.

The Problem of Shipping Wastes

Shipping wastes, long a neglected topic, has started to attract worldwide attention, thanks to the mysterious and tragic disappearance of flight MH370. During the search for MH370, a succession of items floating in the sea were identified as possible wreckage, but later confirmed to be simply pieces of marine litter. Whilst it was large pieces of debris that complicated the search, marine debris of all sizes causes problems for users of marine resources. In the most polluted areas, around 300,000 items of debris can be found in each square kilometre.

Up to 80% of ocean debris originates from land based sources, including beach litter, litter transported by rivers, and discharges of untreated municipal sewage, while ocean based sources (merchant shipping, ferries, cruise liners, fishing and military vessels) account for the remainder. Whilst typically this may be only 20% of marine litter, in areas of high shipping activity such as the North Sea it rises closer to 40%.

Wastes from commercial vessels seems like an area that could be effectively tackled with regulation. However, it is difficult for individual nations or regions to take action when ships operate in international waters and the debris in our oceans is constantly on the move.

So how is it addressed through international legislation?

Law of the Seas

In fact, a good many laws are already in place. The key piece of legislation preventing ‘the disposal of garbage at sea’ is Annex V of the International Convention for the Prevention of Marine Pollution from Ships (MARPOL). Amongst the numerous other relevant laws are the London Convention and Protocol, the Basel Convention, UNCLOS, and the Convention on Biological Diversity.

In addition, many more laws exist at regional and national levels. In the EU, laws directly related to marine debris include the Marine Strategy Framework Directive and the Directive on Port Reception Facilities. Laws indirectly related to marine debris include the Common Fisheries Policy, the Water Framework Directive, the Waste Framework Directive, the Habitats Directive…. The list goes on.

Fathoming the Legislation

Despite the profusion of legislation, the scale of the current and potential problems caused by marine debris, it is clear that implementation and enforcement is lagging behind. Why so?

Ratification

As yet, not all coastal or flag states have ratified international instruments such as MARPOL Annex V. This means that ships registered with a non-ratified state under a‘flag of convenience’ may legally continue to discharge garbage in international waters. However, even if the current suite of international legislation was universally ratified, this would serve to expose the remaining gaps in the framework.

Discharge provisions

MARPOL Annex V includes specific requirements regarding the discharge of different types of waste and location of discharges. For instance, ground food waste can be discharged up to 3 nautical miles from land, but if it is not ground it may only be discharged at a distance of 12 nautical miles or more. Although the discharge of ‘all other garbage including plastics’ is prohibited, compliance relies upon good waste management practices on board vessels.

If waste streams are contaminated, this may result in plastics and other debris being discharged into the sea. The current approach may have been developed to accommodate shipping activity, but in practice it is somewhat confusing and it would perhaps make more sense to issue a blanket ban on discharges.

Scope

Another gap within MARPOL Annex V is the scope of the requirements for ‘garbage management plans’ and ‘garbage record books’. Vessels of 100 gross tonnes or more are required to have a garbage management plan, while vessels of 400 gross tonnes or more are required to have a garbage record book. Smaller vessels are not obliged to comply with the requirements.

Less than 1% of vessels in the world fishing fleet have a gross tonnage of over 100 tonnes, the majority has no obligation to implement and maintain a plan or book; with no planning or record keeping, the risk of illegal disposal is increased. Small fishing vessels may not be considered ‘commercial’ shipping vessels at all – thereby avoiding legislation – but they still contribute towards the problem of marine debris. Most notably, abandoned, lost or otherwise discarded fishing gear has a considerable impact on marine species through ‘ghost fishing’.

Port waste reception facilities

MARPOL Annex V requires the government of each ratified nation to provide facilities at ports for the reception of ship generated residues and garbage that cannot be discharged into the sea. The facilities must be adequate to meet the needs of ships using the port, without causing undue delay to ships. However, MARPOL does not prescribe any set standards or provide for certification. The term ‘adequate’ is instead defined in a qualitative (rather than quantitative) manner in Marine Environment Protection Committee (MEPC) resolution 83 (44).

Furthermore, MARPOL does not set any requirements regarding how waste delivered to port reception facilities should be managed. Only the non-mandatory MEPC resolution 83 (44) requires that facilities should allow for the ultimate disposal of ships’ wastes to take place in an environmentally appropriate way.

Cruise ships

Cruise ships operate in every ocean worldwide, often in pristine coastal waters and sensitive marine ecosystems. Operators provide amenities to their passengers similar to those of luxury resort hotels, generating up to 14 tonnes of waste per day. Worldwide, the cruise industry has experienced a compound annual passenger growth rate of 7% since 1990, and the number of passengers carried is expected to increase from approximately 21 million in 2013 to 23.7 million in 2017.

The majority of current legislation on pollution and ship waste was developed prior to the rapid growth of the cruise market; as a consequence, there is no international legislation addressing the particular issues surrounding pollution and waste management on these vessels.

Although there is not yet data to support this, intuitively the amount of waste produced by ships would be linked to the number of people on board, rather than the vessel’s gross tonnage (which determines whether MARPOL rules apply). If the industry grows as forecasted, cruise ships may be responsible for a significant proportion of waste generated by ships, particularly if unmanned are the future.

To address this, onboard waste management systems that implement zero disposal of solid waste at sea are needed for cruise ships, together with a requirement that they only dispose of their waste at ports with reception facilities adequate to handle the type and volume of waste produced.

Taking the Helm

Where international and regional legislation is found lacking a number of voluntary mechanisms have been devised, indicating an appetite to improve the current waste disposal practices of the shipping industry.

  • The indirect fee system aims to remove the disincentive for ships to dispose of waste at port rather than at sea by including the cost of waste disposal services in the port fees paid by visiting ships, irrespective of whether ships use the facilities
  • The Clean Shipping Index is an easy to use, transparent tool which can be used by cargo owners to evaluate the environmental performance of their sea transport providers. The information is entered on a ship-by-ship basis but is also added to a total carrier fleet score for an overall ranking. Questions on waste relate to garbage handling and crew awareness, and scores can only be obtained for measures that go beyond existing regulations.
  • One commercial container operator (Matson Navigation) has introduced a zero solid waste discharge policy. The ‘greentainer’ programme uses containers specifically designed for storing solid waste. Since 1994, this programme has prevented over 10,000 tonnes of garbage being disposed of at sea.

Currently, international legislation does not properly support a closed loop system for waste management onboard ships. Despite legislative progress and improvements in practice, the monitoring of waste from shipping remains problematic. ‘Policing the seas’ to verify what a ship discharges and where, and whether this follows recommended best practice, remains one of the most challenging aspects of waste management practice at sea, but critical to making the legal framework effective.

The United Nations Environment Programme neatly summarised the issue in 2005:“… marine litter is not a problem which can be solved only by means of legislation, law enforcement and technical solutions. It is a social problem which requires efforts to change behaviours, attitudes, management approaches and multi-sectoral involvement.” 

The limitations of international legislation governing the case of marine litter disposed of at sea do need to be addressed; but unless legislation is accompanied by environmental education for seafarers, and improved monitoring, our attempts to tackle this source of marine litter will remain all at sea.
