What is CNC Turning and What are its Benefits

CNC turning is a manufacturing process that uses a CNC machine to turn a workpiece on its axis. The workpiece is held in place by a chuck or collet and rotated while a tool is moved along the X and Y axes to create the desired shape.

CNC turning offers several benefits over traditional machining methods. First, it is a more efficient use of material. The workpiece is only machined where it needs to be, resulting in less waste. Second, it is a more precise process. CNC machines can produce extremely accurate results, down to the thousandth of an inch. Third, it is a faster process. CNC machines can often produce parts faster than traditional machining methods. Finally, it is a more versatile process. CNC machines can be programmed to produce parts with a wide variety of shapes and sizes.

What is CNC Turning

How Does CNC Turning Work?

The first step in CNC turning is to create a computer model for the desired part. This model can be created using CAD software or by scanning an existing part. Once the model is complete, it is saved as a computer file and imported into the CNC machine.

Selecting the material for the part is the next step. The material is loaded into the machine and the tool paths are programmed. The CNC machine then carves the part from the material. This process is monitored and adjusted as necessary to ensure accurate results.

When the part is finished, it is removed from the machine and cleaned up. It is then ready for use in manufacturing or further processing.

Types of Materials are Best Suited for CNC Turning

Materials that are well suited for CNC turning include metals, plastics, and composites. Metals such as aluminum, brass, and steel are commonly machined using CNC turning. Plastics such as acrylic and polycarbonate can also be turned on a CNC machine. Composite materials, such as fiberglass and carbon fiber, can also be machined using CNC turning.

Why Choose CNC Turning Over Other Manufacturing Methods?

There are several reasons why CNC turning is a better choice than other manufacturing methods. First, it is a more efficient use of material. The workpiece is only machined where it needs to be, resulting in less waste.

Why Biofuels Should Be a Key Part in America’s Future

Biofuels are one of the hottest environmental topics, but they aren’t anything new. When discussing these fuels, experts frequently refer to first, second-and third-generation biofuels to differentiate between more efficient and advanced ones currently in development and more traditional biofuels in use for decades.

Biofuels are increasingly being used to power vehicles around the world

First-generation biofuels are things like methanol, ethanol, biodiesel and vegetable oil, while second-generation biofuels are produced by transforming crops into liquid fuels using highly advanced chemical processes, such as mixed alcohols and biohydrogen. Third-generation, or “advanced” biofuels, are created using oil that is made from algae or closed reactors and then refined to produce conventional fuels such as ethanol, methane, biodiesel, etc.

Cleaner Air and Less Impact on Climate Change

As biofuels come from renewable materials, they have less of an impact on climate change as compared to gasoline, according to multiple studies. Ethanol in gasoline has been helping to decrease smog in major cities, keeping the air cleaner and safer to breathe.

Starch-based biofuels can reduce carbon dioxide emissions by around 30- to 60-percent, as compared to gasoline, while cellulosic ethanol can lessen emissions even further, as much as 90 percent.

Reduced Danger of Environmental Disaster

Can you imagine buying one of the oceanfront Jacksonville condos in Florida, looking forward to enjoying peaceful beach strolls every morning only to find injured or killed animals and globs of oil all over the sand? Not exactly the vision of paradise you dreamed of.

A major benefit of using biofuels is the risk of environmental disaster is dramatically reduced. The 2010 Deepwater Horizon Spill that occurred in the Gulf of Mexico released millions of gallons of oil. It not only cost BP nearly $62 billion but caused extensive damage to wildlife and the environment. Biofuels are much safer. For example, a corn field won’t poison the ocean.

More Jobs and an Economic Boom

Numerous studies, including one conducted by the Renewable Fuels Association (RFA), have found that biofuels lead to more jobs for Americans. In 2014, the ethanol industry was responsible for nearly 84,000 direct jobs and over 295,000 indirect and induced jobs – all jobs that pay well and are non-exportable. The biofuels industry in the USA also added nearly $53 billion to the national GDP, $27 billion to the national GDP and over $10 billion in taxes, stimulating local, state and national economies.

Many experts predict that these figures will increase with significant job creation potential in biorefinery construction, operation and biomass collection. If the potential for producing cellulosic ethanol from household waste and forestry residues were utilized at commercial scale, even more jobs are likely to be added.

Energy Independence

When a nation has the land resources to grow biofuel feedstock, it is able to produce its own energy, eliminating dependence on fossil fuel resources. Considering the significant amount of conflict that tends to happen over fuel prices and supplies, this brings a net positive effect.

A Glance at College Recycling Programs

Just one look at your local landfill is enough to convince you that there is a need for more recycling programs. Recycling should be a priority for all institutions across the country. College recycling programs ensure that such institutions make a contribution to environmental conservation.

Every student should have a recycle bin where they dispose of recyclable materials like paper, batteries, water bottles, and so much more. The world is going through a green resource transition, and college institutions such as essay writer helper should not be left behind.

 

Local communities can also borrow a leaf from college institutions and recycle their waste. The internet is quite resourceful when it comes to researching how a recycling program should work. Students can also use online resources to make their school life easier. For instance, thesis writing services ensure students get the marks they need to graduate.

1. American University

American University strives to be 100% waste-free. Its zero waste policy was adopted in 2010, and since then, the institution has had significant milestones. The system ensures that all university wastes are diverted from landfills. AU uses only renewable materials to ensure no waste is going into the environment.

The university’s environmental conservation efforts ensure it maintains a healthy student community. AU’s fraternity practices sustainable purchasing to maintain an environmentally-friendly campus.

AU makes paper towels from restrooms as well as kitchen wastes. The elimination of water bottles and food trays also helps cut down on wastes. The kitchen grease is recycled for electricity to help manage utility bills.

This institution has one of the finest recycling systems in America’s academic scene. In 2012, the school beat over 600 other universities at a RecycleMania contest.

2. Valencia College

Valencia College has a decade-old recycling system that’s updated each year. The institution has established itself as the model for university sustainability by bagging RecycleMania gold for waste minimization from 2012 through to 2014.

The school encourages students to reduce their waste output. It has a seamless paper, aluminum, plastic, and e-waste management system in place. The school no longer uses water bottles as this is the source of plastic waste in many institutions. Valencia College recycling program aims to reduce the institution’s carbon footprint.

3. College of the Atlantic

College of the Atlantic is well known as the greenest university college in the country. The institution’s recycling system is a comprehensive program that offers outlets for all types of waste.

Aside from outlets for food, the university also has units for composting disposable flatware and kitchen napkins. For foods that cannot be recycled, the campus uses these as a source of renewable energy. The recycling program is run by students to teach them the importance of environmental conservation.

4. University of California

One of University California’s goals is to achieve zero waste by 2020. A 90% waste diversion from landfills will have a significantly positive impact on the environment. The campus also aims to phase out procurement and distribution of Expanded Polystyrene.

Within the institution, is a hub for repurposing items. Students also collect leftover food in their rooms. The school rethinks daily operations to achieve a comprehensive diversion campaign.

5. Kalamazoo College

Kalamazoo College is another higher learning institution with comprehensive waste management and recycling program. The school not only recycles but also donates stationery, mirrors, lamps, and so much more to the surrounding community.

The school’s recycling department handles the exportation of food waste to a local pig farm. Kalamazoo College also recycles e-wastes like batteries, calculators and electric motors.

In addition to recycling, the department also takes up reuse and waste reduction responsibilities. The recycling department is run by students under the supervision of staff in charge. This way, students can understand just how much waste goes into the environment. The campus has two dedicated electric-powered golf carts that help with transportation of waste.

6.     Harvard University

Harvard University is one of the institutions that adopted the single-stream recycling. This means that all recyclable materials are mixed together in one waste receptacle. This is an effective system because it eliminates any confusion or guesswork.

The school runs a recycling program for different kinds of waste, including e-waste, food, ink, paper, and cartridges. Over the years, the recycling program has evolved and improved in efficacy. The school uses competitions to encourage students to reduce waste.

Conclusion

College recycling programs ensure students learn the importance of environment conservation. Institutions of higher learning are an excellent platform to teach students about environmental friendliness. Diverting waste from landfills ensures they don’t overflow with items that can be reused or recycled.

Municipal Solid Waste Management in Oman

Municipal solid waste management is a challenging issue for the Sultanate of Oman. With population of almost 3 million inhabitants, the country produces about 1.9 million tons of solid waste each year. The per capita waste generation in Oman is more than 1.5 kg per day, among the highest worldwide.

Landfill_Middle_East

Prevalent Scenario

Solid waste in Oman is characterized by very high percentage of recyclables, primarily paper (26%), plastics (12%), metals (11%) and glass (5%). However the country is yet to realize the recycling potential of its municipal waste stream.

The predominant waste disposal method in Oman is landfilling. Most of the solid waste is sent to authorized and unauthorized dumpsites for disposal which is creating environment and health issues. There are several dumpsites which are located in the midst of residential areas or close to catchment areas of private and public drinking water bodies.

Solid waste management scenario in Oman is marked by lack of collection and disposal facilities, as well as lack of public awareness about waste in the country. Solid waste, industrial waste, e-wastes etc are deposited in very large number of landfills scattered across the country. Oman has around 350 landfills/dumpsites which are managed by municipalities. In addition, there are numerous unauthorized dumpsites in Oman where all sorts of wastes are recklessly dumped.

Al Amerat Sanitary Landfill

Al Amerat landfill is the first engineered sanitary landfill in Oman which began its operations in early 2011. The landfill site, spread over an area of 9.6 hectares, consists of 5 cells with a total capacity of 10 million m3 of solid waste and spread over an area of over 9.6 hectares. Each cell has 16 shafts to take care of leachate (contaminated wastewater).

All the shafts are interconnected, and will help in moving leachate to the leachate pump. The project is part of the government’s initiatives to tackle solid waste in a scientific and environment-friendly manner. Being the first of its kind, Al Amerat sanitary landfill is expected to be an example for the future solid waste management projects in the country.

The Way Forward

Solid waste management is among the top priorities of Oman government which has chalked out a robust strategy to resolve waste management problem in the Sultanate. The country is striving to establish 16 engineered landfills, 65 waste transfer stations and 4 waste treatment plants in different parts of the country.

Modern solid waste management facilities are under planning in several wilayat, especially Muscat and Salalah. The new landfills will eventually pave the way for closure of authorized and unauthorized garbage dumps around the country. However investments totaling Omani Rial 2.5 billion are required to put this waste management strategy into place. Oman is also seriously exploring waste-to-energy as a tool to manage garbage in a sustainable manner.

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.

A Beginner’s Guide To Investing In Oil

Thanks to the Internet, you do not have to move to an oil rich country, such as Russia or the United States of America, to be able to invest in this commodity. Even better is that you do not need a lot of money to do it either. A good oil investments opportunity does not have to cost you the Earth.

How To Invest In Oil

How To Invest In Oil

There are a number of different ways that a person can invest in oil, with most of them not requiring you to physically hold the commodity. For example, you can invest in stocks that are related to oil, oil futures, and mutual funds. However, in order to be able to do any of these things, you must have a brokerage account.

1. Oil stocks

These allow you to invest directly in the companies that are involved in the extraction and production of petroleum from the Earth. It is important that you do lots of research before making a purchase of a stock or stocks in a particular company. It is prudent to have a diverse portfolio in index or mutual funds rather than just individual stocks.

2. Oil futures

This is an advanced way of investing in oil and allows oil producers to lock in a certain price for the commodity in advance. The same is also true for investors – the price at which they are purchasing the commodity at is also locked in. They are essentially contracts between the two parties to agree to exchange an agreed upon amount of oil for a certain price on a specified date.

So when trading these types of investments, it is actually the contract that you are trading, rather than the actual commodity. When there is a fluctuation in the price of oil, the contract could become more valuable and it is at that point that you should sell it for a decent profit. However, the opposite can also be true and you could end up losing money with this type of investment.

Risks of the Oil and Gas Industry

3. Oil mutual funds

These are like baskets of oil stocks that investors are able to purchase all at once. Index funds and exchange traded funds are a great way of easily and quickly diversifying your portfolio. However, this diversity is diminished when only investing in an oil mutual fund. Also if the industry was to suffer for whatever reason, oil mutual funds would perform worse than a more diverse investment fund.

How Much Money Do You Need To Invest In Oil?

Investing in oil can be done by most people regardless of their income – you do not have to be super rich. There are quite a few oil stocks that are well known and that trade for less than $100 each. EFTs also provide another cheap way of investing in oil. They are traded on an exchange and individual’s are able to buy these shares just like they can stocks. Lots of EFTs are valued at less than $30 each.

Medical Waste Management in Developing Countries

Healthcare sector is growing at a very rapid pace, which in turn has led to tremendous increase in the quantity of medical waste generation in developing countries, especially by hospitals, clinics and other healthcare establishments. The quantity of healthcare waste produced in a typical developing country depends on a wide range of factors and may range from 0.5 to 2.5 kg per bed per day.

medical-waste-management

For example, India generates as much as 500 tons of biomedical wastes every day while Saudi Arabia produces more than 80 tons of healthcare waste daily. The growing amount of medical wastes is posing significant public health and environmental challenges across the world. The situation is worsened by improper disposal methods, insufficient physical resources, and lack of research on medical waste management. The urgent need of the hour is to healthcare sustainable in the real sense of the word.

Hazards of Healthcare Wastes

The greatest risk to public health and environment is posed by infectious waste (or hazardous medical waste) which constitutes around 15 – 25 percent of total healthcare waste. Infectious wastes may include items that are contaminated with body fluids such as blood and blood products, used catheters and gloves, cultures and stocks of infectious agents, wound dressings, nappies, discarded diagnostic samples, swabs, bandages, disposal medical devices, contaminated laboratory animals etc.

Improper management of healthcare wastes from hospitals, clinics and other facilities in developing nations pose occupational and public health risks to patients, health workers, waste handlers, haulers and general public. It may also lead to contamination of air, water and soil which may affect all forms of life. In addition, if waste is not disposed of properly, ragpickers may collect disposable medical equipment (particularly syringes) and to resell these materials which may cause dangerous diseases.

In some countries, there may be legal remedies for such losses. For example, Floridians in the US can go to a medical malpractice lawyer in West Palm Beach. In others, especially developing countries, it may be harder to get compensated, and disease may be spread more easily as a result.

Inadequate healthcare waste management can cause environmental pollution, growth and multiplication of vectors like insects, rodents and worms and may lead to the transmission of dangerous diseases like typhoid, cholera, hepatitis and AIDS through injuries from syringes and needles contaminated with human.

In addition to public health risks associated with poor management of biomedical waste, healthcare wastes can have deleterious impacts on water bodies, air, soil as well as biodiversity. The situation is further complicated by harsh climatic conditions in many developing nations which makes disposal of medical waste more challenging.

healthcare-waste-india

The predominant medical waste management method in the developing world is either small-scale incineration or landfilling. However, the WHO policy paper of 2004 and the Stockholm Convention, has stressed the need to consider the risks associated with the incineration of healthcare waste in the form of particulate matter, heavy metals, acid gases, carbon monoxide, organic compounds, pathogens etc.

In addition, leachable organic compounds, like dioxins and heavy metals, are usually present in bottom ash residues. Due to these factors, many industrialized countries are phasing out healthcare incinerators and exploring technologies that do not produce any dioxins. Countries like United States, Ireland, Portugal, Canada and Germany have completely shut down or put a moratorium on medical waste incinerators.

Alternative Medical Waste Treatment Technologies

The alternative technologies for healthcare waste disposal are steam sterilization, advanced steam sterilization, microwave treatment, dry heat sterilization, alkaline hydrolysis, biological treatment and plasma gasification.

Steam sterilization is one of the most common alternative treatment method. Steam sterilization is done in closed chambers where both heat and pressure are applied over a period of time to destroy all microorganisms that may be present in healthcare waste before landfill disposal. Among alternative systems, autoclaving has the lowest capital costs and can be used to process up to 90% of medical waste, and are easily scaled to meet the needs of any medical organization.

Advanced autoclaves or advanced steam treatment technologies combine steam treatment with vacuuming, internal mixing or fragmentation, internal shredding, drying, and compaction thus leading to as much as 90% volume reduction. Advanced steam systems have higher capital costs than standard autoclaves of the same size. However, rigorous waste segregation is important in steam sterilization in order to exclude hazardous materials and chemicals from the waste stream.

Microwave treatment is a promising technology in which treatment occurs through the introduction of moist heat and steam generated by microwave energy. A typical microwave treatment system consists of a treatment chamber into which microwave energy is directed from a microwave generator. Microwave units generally have higher capital costs than autoclaves, and can be batch or semi-continuous.

Chemical processes use disinfectants, such as lime or peracetic acid, to treat waste. Alkaline hydrolysis is a unique type of chemical process that uses heated alkali to digest tissues, pathological waste, anatomical parts, or animal carcasses in heated stainless steel tanks. Biological processes, like composting and vermicomposting, can also be used to degrade organic matter in healthcare waste such as kitchen waste and placenta.

Plasma gasification is an emerging solution for sustainable management of healthcare waste. A plasma gasifier is an oxygen-starved reactor that is operated at the very high temperatures which results in the breakdown of wastes into hydrogen, carbon monoxide, water etc. The main product of a plasma gasification plant is energy-rich syngas which can be converted into heat, electricity and liquids fuels. Inorganic components in medical wastes, like metals and glass, get converted into a glassy aggregate.

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.

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.

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.

Impact of Whitening Mouthwash on Teeth Whitening Treatment

According to a study published in the American Journal of Orthodontics and Dentofacial Orthopedics, more than 90 percent of dental and orthodontic patients also request tooth whitening. The fact is, as no less than Inc. magazine recently reported, having a bright white smile you love to show off is important for every goal you have in life. People who smile more tend to make more money, receive more frequent promotions, look younger, have more friends and connections, feel better, live longer, lead better and be happier.

No wonder there is so much demand for teeth whitening services! But how can you tell all the different options apart and figure out which is best for you? And how can you maximize the results of your in-office teeth whitening? Should you use over-the-counter options like whitening mouthwash or will that hurt your results? Find out in this blog post.

How the Teeth Whitening Process Works

The American Dental Association (ADA) highlights how important it is to understand how the process of teeth whitening really works.

Once you understand the basic underlying mechanism behind teeth whitening you will be in a much better position to maintain your teeth whitening results long term.

The ADA explains that there are two basic types of teeth whitening and both are bleaches. The two types are carbamide peroxide and hydrogen peroxide.

Regardless of the bleaching type you choose, the way they work is basically the same. Once applied, the bleaches go to work to dismantle tooth stains bit by tiny bit, almost like a tiny eraser.

How Do Tooth Stains Develop?

Marc Lazare, teeth whitening expert in New York, notes that tooth stains can develop in any number of ways and for a wide variety of reasons.

Different stains may be easier or harder to lift. Generally, lighter stains such as yellowing are easier to bleach away, while gray or brown stains are more resistant to whitening efforts. Some stains, such as those caused by mouth trauma or injury, may not respond to bleaching much if at all.

As well, it is important to be aware that teeth whitening treatments generally do not work on dental prosthetics such as implants, bridges, veneers or crowns.

The most common causes of tooth stains include:

1. Food and drink

If you have ever had to go to the sink to wash dark blueberry stains off your fingertips, you already understand how food and drink can stain your teeth.

Over time and with repeated exposure (such as that daily morning cup of coffee) your teeth will become increasingly less white.

2. Smoking and nicotine use

Smoking, vaping, snuff, gum and other sources of nicotine can stain your teeth quite badly over time, and the brown stains are some of the harder stains to lift.

3. Injury or trauma

If you have experienced an injury or trauma to your mouth or teeth, injured nerves and blood vessels may cause tooth discoloration.

4. Medication use

Medications used to treat cancer such as chemotherapy and radiation are some of the best-known drugs that can cause tooth discoloration. Another common culprit is the acne medicine tetracycline, which can cause lasting tooth discoloration.

5. The natural aging process

The natural process of aging can also cause the tooth enamel to wear thin and look less white and more yellow over time.

Will Whitening Mouthwash Help or Hurt?

To date, research shows that whitening mouthwash is not harmful to teeth that have been professionally whitened.

While a whitening mouthwash is unlikely to deliver comparable results to the outcome of a professional teeth whitening treatment, even when used consistently over time, it is equally unlikely to degrade or interfere with the results you get from professional teeth whitening.

Too-frequent use of any product designed to bleach and whiten teeth can sometimes cause temporary tooth sensitivity. Patients who experience tooth sensitivity from any tooth whitening product generally find that this side effect fades after a few days of not using the product.

How to Choose a Whitening Mouthwash

According to the ADA, the best whitening mouthwash will also provide other important oral health benefits, such as helping to control tartar and plaque buildup on teeth, guarding against decay and dental caries, fighting back against gum inflammation and infection (gingivitis/periodontal disease) and, of course, improving breath.

The ADA specifies two different categories of mouthwash: cosmetic and therapeutic. It is important to note that a mouthwash can serve both purposes, such as a whitening mouthwash that also provides health benefits such as the ones just mentioned here.

Some of the best whitening mouthwashes will themselves require a prescription from your dentist or orthodontist. These mouthwashes are often recommended as a follow-up to a professional teeth whitening treatment and for daily use after preventative dental care or dental treatment.

The more you can do to improve your overall oral health by brushing, flossing, gargling with mouthwash and choosing your daily menu with tooth health and color in mind, the longer your teeth whitening results will last.
