This article is going to look a little closer at Stellar Lumens, as well as go over its history and future outlook. So read on to learn a little bit more about what makes it one of the most exciting networks and platforms in the industry.

What are Stellar and Lumens?

As mentioned, Stellar was created as a network for people and financial institutions all over the world with the purpose of sending money easily, quickly, and affordably. It allows you to send a variety of different currencies, both fiat and crypto, in a way that is more reliable than traditional methods.

The benefits of Stellar include cryptocurrency transactions that take seconds, low transaction costs when compared to wire transfers, and the fact that it is incredibly easy to access and exchange different currencies. Stellar is also secure as the network has never experienced a hack, despite being in an industry that is so frequently targeted.

The network runs on decentralized servers and relies on their built-in token called Lumens to operate. They can easily be purchased on many exchanges. If you wish to convert other crypto you own to Lumens, you can use specialized services, like this eth to xlm converter by Godex. You can exchange numerous coins including Stellar Lumen, Bitcoin, Ethereum, Litecoin, Monero, and many others.

Lumens not only assist with multi-currency transactions but also act as a spam deterrent. Stellar requires that every account hold some Lumens at all times. It is done to prevent the ledger from being overrun with spam or making it too easy to use the ledger. The amount required is minuscule, just enough to deter large amounts of spam. In addition to this, Lumens are also used to pay transaction fees.

The History of Stellar Lumens

Stellar began in 2014 and was co-founded by Jed McCaleb, who is no stranger to the industry. He was also the co-founder of Ripple, which is actually among the biggest competitors to Stellar. Stellar was brought into the world to assist in making cross-border payments more efficient.

These payments have traditionally been incredibly expensive and taken a very long time to complete. Economic experts preach about the importance of easy access to financial services. But, unfortunately, many around the world don’t have access to banks and other institutions.

Since 2014, Stellar has partnered with several companies and platforms to service people all over the world. While the growth has been impressive, there is still a lot of progress to be made.

The advisory team behind Stellar is also impressive and one of the reasons why people are optimistic about its future. Some members of the board are the founder of AngelList, the founder of WordPress, and the CEO of Stripe, who is one of the youngest billionaires on the planet. With a team like this on the board, Stellar has some of the brightest minds in tech behind it.

There is also the Stellar Development Foundation. Its main goal is to increase awareness around the existence of Stellar. It also ensures the interface and platform are user-friendly, simple, and affordable for people all over the world to send and receive money.

Future Outlook and Performance of Stellar Lumens

So what does the future hold for Stellar Lumens? Well, we believe it will only continue to get more popular. The services they offer (and their benefits) are easy to understand, and the problem they set out to solve is a big one for millions all over the world. As they continue to build out their system and reputation and increase their partnerships, many believe Stellar Lumens could be the future of borderless payments.

In addition to their practical use cases, Lumens can also act as an investment, like many other cryptocurrencies. Expert opinion is mixed. However, many believe that the cryptocurrency should only increase in value. The reason is the increased usage and understanding across the world. Like many other assets, the performance of Lumens is also tied to Bitcoin and the crypto market as a whole.

In conclusion, we hope that this article has been able to help you learn more about Stellar Lumens. They are an exciting cryptocurrency and platform, and one that is sure to help people transfer funds all over the world.

4 Ways To Pay Your Electricity Bill Effortlessly

  By | | , , ,
20 Comments

Utilities like water and power can end up costing nearly as much as your rent or house payment in a bad month. Unfortunately, you can’t cut off your water service to save money the way you could cut the cable. Here are a few tips to tame your utility bills and make it easier to pay your electricity bill with ease.

1. Clean Up

Cleaning the coils on your refrigerator helps it work more efficiently. Cleaning the coils on your air conditioner can do the same, but your AC uses far more power than your fridge. Remove any debris from the air intakes, whether it is leaving piles up by the AC or the air vent to your furnace. Rinse the air filters for your room air filters, the air conditioner, and your dehumidifier.

2. Turn It Off

While the appliances that are sleeping may use less energy than when on, the reality is that they use almost as much power in standby as they do when active. The solution is to turn things off. Unless your game station is downloading updates, unplug it to save power. Turn off the TV instead of letting it sit in standby, or worse, use it as background noise.

When gadgets are fully charged, disconnect them from the charging station and turn off the charging station. If you can’t stand to turn off your computer, turn off the monitor instead. Turn off lights when they aren’t in use, and consider when you can utilize natural light instead. Don’t let appliances idly run while you’re busy. Get the clothes out of the dryer instead of letting it run every five minutes to prevent clothes from wrinkling.

Turn off the oven when you’re done with it. The same might be said for your pool pump or air filters. Does it need to be running? If not, consider turning it off for a while. Always aim to improve your habits and to acquire energy-saver appliances. Also, consider that you are still allowed to hire a better energy provider in case the current one is not the best fit regarding your lifestyle. For instance, there are plenty of options when it comes to the most suitable electric companies in dallas.

3. Track Energy Usage

You can get apps that report energy usage in your home. These apps can tap into your smart meter and tell you which appliances are consuming the most energy. If you can’t cut back on energy usage, you could get advice on how to shift energy usage in order to reduce your electric bill.

For example, running the clothes dryer at night may allow you to get utility discounts. One of the advantages of hydroelectric energy is that despite facing daily and seasonal variations, utility companies will still provide discounts when the demand for power is lower.

Set up the dishwasher to run a heavy load when you go to bed, and the cost per kilowatt maybe a third of what you’d pay if it ran during the day. You may also find that the AC is running heavily during the hottest part of the day.

Could you alter the thermal profile of your home so that it uses less energy while keeping you comfortable, such as not trying to keep the house at 65 when you’re at work? If you cannot get the house comfortable without the AC running full blast all the time, you may need to have the air conditioner repaired or replaced with a more powerful unit.

4. Check for Leaks

If you’ve ever heard the joke that you’re not heating the neighborhood, recognize that there is an element of truth to that joke. When you leave the door open while you’re bringing in groceries or getting the mail, you’re wasting the energy used to heat or cool that air. Gaps in your window frame and window stripping cost you the same way.

Leaks in your hot water heater waste both water and the energy used to heat it. Look for water leaks when you suspect them, too. Not only does this damage the structure of your home and wastewater, but damp insulation has a fraction of the thermal value of dry insulation. This is how a water leak could be contributing to your higher energy bills.

There are a number of things you can do to reduce your energy bills and water bills without radically changing your lifestyle. Then you’ll be able to save the Earth’s resources and money at the same time. It is truly a win-win for everyone.

Sharing Economy: Why This is Growing in Popularity and Benefits All

  By | | ,
1 Comment

If you haven’t heard of the sharing economy, I bet you will want to get involved after reading this. The sharing economy is a growing trend around the world. It’s based on the idea that there are many things we don’t use every day or even every week, and by sharing them with other people, we can reduce our costs while giving others access to items they might not otherwise have. In this article, I will explain the benefits and some examples of how you can use the sharing economy to make your life easier and reduce costs.

benefits of sharing economy

Some popular sharing economy examples

There are many sharing economy examples, but some of the most popular ones are:

1. Airbnb

If you’ve heard of Airbnb, then you know that it’s a website that allows people to rent out their homes for stays in other parts of the world. The idea behind Airbnb is that people worldwide have unused space in their homes, which they can use to earn money. In addition to providing travelers with affordable accommodations, Airbnb also gives homeowners in different countries opportunities to meet and learn from one another.

2. Uber

Uber, a ride-sharing app, was founded in 2009. It’s available in over 800 cities in 65 countries and 450 in the United States. Uber is also available in over 100 cities in Canada and 50 cities in Mexico. What makes Uber different from other ride-sharing apps like Lyft or Sidecar is that you can request a car using the app on your smartphone, which will be sent to pick you up by one of their drivers. In addition, you can pay for your ride through the app using either cash or a credit card once you arrive at your destination.

3. Shared parking

This is a great way to save money on parking. It’s a good option for people who live in cities and don’t have cars, but it can also work well for people who own cars and want to find more affordable long-term parking options. Here’s how shared parking works: You sign up with an app, and you use your app to find out which spots are available at a lot near you (lots offer different rates depending on the location). When you see one that fits your needs, you reserve it with your app and pay through the app. Then when you get there, swipe your card at the gate and go park!

4. Car-sharing

Car sharing is a great way to save money on car ownership. With the help of an app, you can rent a car by the hour, day or week—and you don’t even need to leave your apartment. Simply download a car-sharing app such as Zipcar or Car2Go and search for vehicles near your location. You’ll find cars in most big cities across North America and Europe. Multiple companies operate these programs, so they offer different models (sedans, SUVs) at different prices depending on how often you want to use them and how long you drive them each time.

If you are looking to reduce costs further, you can search for parking over a longer term. Daily parking is often much more expensive than booking monthly. For example, in Philadelphia monthly parking options are available from $100, whereas daily rates start at $2 an hour, so if you travel five days a week and park for 8 hours a day, that is a massive saving of around $220 a month.

What is the sharing economy?

The sharing economy is a model where individuals can rent or borrow assets owned by another person. It involves the sharing of things and services, not the ownership of them.

For example, Uber allows you to get a ride from someone driving their car as long as that person has been vetted by the company and passed a background check. It’s not about renting a car from Uber; it’s about meeting your transportation needs through a driver you trust. That’s what makes this model so appealing: By using services such as TaskRabbit (a website where people can find local help), Airbnb (where you can rent out your apartment when you’re out of town), or YouBike (which allows users to use bicycles for short trips around cities in China), customers can meet their needs without buying new items themselves. This means less waste and more sustainability!

What are the benefits of the sharing economy?

There are several benefits to the sharing economy, which include:

  • Reduced cost – You can save money on groceries and clothing by sharing an item rather than purchasing it yourself.
  • Reduced waste – Sharing items means less waste from unused or unwanted products thrown away yearly. In America alone, that is about $160 billion worth.
  • You have increased community engagement and trust.
  • Increased employment opportunities (especially in rural areas). Encouraging people who otherwise wouldn’t work outside their homes to get out there again help create jobs while also reducing stress levels overall within society at large!

How can I get involved with the sharing economy?

It can be a bit overwhelming if you’re new to the sharing economy. However, there are so many different ways you can get involved!

  • Share your resources – If you have extra space in your home, rent them on Airbnb or Turo. You could also rent out unused tools and furniture through websites like RentYourTools or Peerby. Renting out your parking space is another way to share resources.
  • Share others’ resources. By connecting people who need specific items with those who have them, services like SwapThing let users save money while reducing waste—a win-win! For example: If someone has an old phone but needs a new one, they can post an ad for their old smartphone; someone who needs a new device will then contact the original owner with details about how much they’d be willing to pay for it (or vice versa). This type of exchange might seem odd at first glance, but it actually makes a lot of sense when both parties benefit from finding each other instead of purchasing brand-new goods that go straight into landfills after only being used once or twice!
  • Share time/skills/knowledge/skills: Use sites like TaskRabbit where people post jobs that need doing around their house (elderly care – cleaning – gardening) etc., along with what they’d pay per hour/day etc. Then all interested parties bid on those jobs until someone gets hired…and paid accordingly!

Conclusion

I am excited to be part of a movement changing how we think about ownership. Sharing resources, we help save money, build community, reduce waste (of course), and build trust. I hope this list has inspired you to start thinking differently about your possessions—and maybe even try out some new ones!

Trends in Waste-to-Energy Industry

  By | | ,
5 Comments

The increasing clamor for energy and satisfying it with a combination of conventional and renewable resources is a big challenge. Accompanying energy problems in almost all parts of the world, another problem that is assuming critical proportions is that of urban waste accumulation. The quantity of waste produced all over the world amounted to more than 12 billion tonnes in 2006, with estimates of up to 13 billion tonnes in 2011. The rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential increase in waste generation of up to 18 billion tonnes by year 2020. Ironically, most of the wastes are disposed of in open fields, along highways or burnt wantonly.

Waste-to-Energy-Industry

Size of the Industry

Around 130 million tonnes of municipal solid waste (MSW) are combusted annually in over 600 waste-to-energy (WTE) facilities globally that produce electricity and steam for district heating and recovered metals for recycling. The global market for biological and thermochemical waste-to-energy technologies is expected to grow to USD 29.2 billion by 2022. Incineration, with energy recovery, is the most common waste-to-energy method employed worldwide.

Since 1995, the global WTE industry increased by more than 16 million tonnes of MSW. Over the last five years, waste incineration in Europe has generated between an average of 4% to 8% of their countries’ electricity and between an average of 10% to 15% of the continent’s domestic heat.

Advanced thermal technologies, like gasification and pyrolysis, and anaerobic digestion systems are beginning to make deep inroads in the waste-to-energy sector and are expected to increase their respective market shares on account of global interest in integrated waste management framework in urban areas. Scarcity of waste disposal sites coupled with growing waste volumes and solid waste management challenges are generating high degree of interest in energy-from-waste systems among policy-makers, urban planners, entrepreneurs, utility companies etc.

Regional Trends

Currently, the European nations are recognized as global leaders of waste-to-energy movement. They are followed behind by the Asia Pacific region and North America respectively. In 2007 there are more than 600 WTE plants in 35 different countries, including large countries such as China and small ones such as Bermuda. Some of the newest plants are located in Asia. China is witnessing a surge in waste-to-energy installations and has plans to establish 125 new waste-to-energy plants during the twelfth five-year plan ending 2015.

Incineration is the most common waste-to-energy method used worldwide.

The United States processes 14 percent of its trash in WTE plants. Denmark, on the other hand, processes more than any other country – 54 percent of its waste materials. As at the end of 2008, Europe had more than 475 WTE plants across its regions – more than any other continent in the world – that processes an average of 59 million tonnes of waste per annum. In the same year, the European WTE industry as a whole had generated revenues of approximately US$4.5bn.

Legislative shifts by European governments have seen considerable progress made in the region’s WTE industry as well as in the implementation of advanced technology and innovative recycling solutions. The most important piece of WTE legislation pertaining to the region has been the European Union’s Landfill Directive, which was officially implemented in 2001 which has resulted in the planning and commissioning of an increasing number of WTE plants over the past five years.

Description of a Biogas Power Plant

  By | | , , ,
14 Comments

A biogas plant is a decentralized energy system, which can lead to self-sufficiency in heat and power needs, and at the same time reduces environmental pollution. The key components of a modern biogas power (or anaerobic digestion) plant include: manure collection, anaerobic digester, effluent treatment, biogas storage, and biogas use/electricity generating equipment.

anaerobic_digestion_plant

Working of a Biogas Plant

The fresh organic waste is stored in a collection tank before its processing to the homogenization tank which is equipped with a mixer to facilitate homogenization of the waste stream. The uniformly mixed waste is passed through a macerator to obtain uniform particle size of 5-10 mm and pumped into suitable-capacity anaerobic digester where stabilization of organic waste takes place.

In anaerobic digestion, organic material is converted to biogas by a series of bacteria groups into methane and carbon dioxide. The majority of commercially operating digesters are plug flow and complete-mix reactors operating at mesophilic temperatures. The type of digester used varies with the consistency and solids content of the feedstock, with capital investment factors and with the primary purpose of digestion.

Biogas Cleanup

Biogas contain significant amount of hydrogen sulfide (H2S) gas which needs to be stripped off due to its highly corrosive nature. The removal of H2S takes place in a biological desulphurization unit in which a limited quantity of air is added to biogas in the presence of specialized aerobic bacteria which oxidizes H2S into elemental sulfur.

Utilization of Biogas

Biogas is dried and vented into a CHP unit to a generator to produce electricity and heat. The size of the CHP system depends on the amount of biogas produced daily.

Treatment of Digestate

The digested substrate is passed through screw presses for dewatering and then subjected to solar drying and conditioning to give high-quality organic fertilizer.  The press water is treated in an effluent treatment plant based on activated sludge process which consists of an aeration tank and a secondary clarifier. The treated wastewater is recycled to meet in-house plant requirements.

Monitoring of Environmental Parameters

A chemical laboratory is necessary to continuously monitor important environmental parameters such as BOD, COD, VFA, pH, ammonia, C:N ratio at different locations for efficient and proper functioning of the process.

Control System

The continuous monitoring of the biogas plant is achieved by using a remote control system such as Supervisory Control and Data Acquisition (SCADA) system. This remote system facilitates immediate feedback and adjustment, which can result in energy savings.

Municipal Solid Wastes in Bahrain

Bahrain has the distinction of being one of the highest per capita municipal solid waste generators worldwide estimated to be more than 1.80 kg per person per day. Infact, Bahrain produces largest amount of waste per person among GCC countries despite being the smallest nation in the region. Rising population, high waste generation growth rate, limited land availability and scarcity of waste disposal sites has made solid waste management a highly challenging task for Bahrain’s policy-makers, urban planners and municipalities.

Bahrain_Wastes

Municipal Solid Wastes in Bahrain

Bahrain generates more than 1.2 million tons of solid wastes every year. Daily garbage production across the tiny Gulf nation exceeds 4,500 tons. Municipal solid waste is characterized by high percentage of organic material (around 60 percent) which is mainly composed of food wastes.

Presence of high percent of recyclables in the form of paper (13 percent), plastics (7 percent) and glass (4 percent) makes Bahrain’s MSW a good recycling feedstock, though informal sectors are currently responsible for collection of collection of recyclables and recycling activities

The Kingdom of Bahrain is divided into five governorates namely Manama, Muharraq, Middle, Southern and Northern. Waste collection and disposal operation in Bahrain is managed by a couple of private contractors. The prevalent solid waste management scenario is to collect solid waste and dump it at the municipal landfill site at Askar.

Askar, the only existing landfill/dumpsite in Bahrain, caters to municipal wastes, agricultural wastes and non-hazardous industrial wastes. Spread over an area of more than 700 acres, the landfill is expected to reach its capacity within the next few years. The proximity of Askar landfill to urban habitats has been a cause of major environmental concern. Waste accumulation is increasing at a rapid pace which is bound to have serious impacts on air, soil and groundwater quality in the surrounding areas.

Conclusions

The Kingdom of Bahrain is grappling with waste management problems arising out of high population growth rate, rapid industrialization, high per capita waste generation, unorganized SWM sector, limited land resources and poor public awareness.

The government is trying hard to improve waste management scenario by launching recycling initiatives, waste-to-energy project and public awareness campaign. However more efforts, in the form of effective legislation, large-scale investments, modern SWM technology deployment and environmental awareness, are required from all stake holders to implement a sustainable waste management system in Bahrain.

Methods For Heavy Metal Analysis

  By | | , ,
2 Comments

A heavy metal analysis can be a useful tool for evaluating soil contamination. It determines the amount of elements in a sample, which indicates the dispersion and level of contamination. Fortunately, there are several methods available for environmental analysis. In this article, we will discuss some of them.

Methods to analyze heavy metals

Inductively Coupled Plasma Mass Spectroscopy (ICP-MS)

ICP-MS is a method for quantitative analysis of heavy elements. It uses a laser ablation system to analyze solid samples, requiring minimal sample preparation. The method has a single side-effect, minor depletion of the sample material. However, this side-effect is acceptable for most applications.

ICP-MS is a highly sensitive method for heavy metal analysis, and it is widely used for determining concentrations of elements. The method works by introducing a fine aerosol of the sample to a plasma containing 6000-10,000 K. The plasma causes the atoms of the analyte to be ionized at the same time. The ions are then sorted and quantified.

The ICP-MS is capable of detecting the smallest particles, and it is also able to detect elements with very low ppt (parts-per-trillion) levels. Although the method does not have the accuracy of ICP-OES, it is able to detect elements with a much lower ppt (parts-per trillion).

ICP-MS is a fast and reliable technique for elemental analysis. It is particularly useful for measuring the isotopic ratios of elements with multiple isotopes. Click here to learn more about isotopes. Its high speed and low detection limits make it a highly versatile analytical tool. Because of these characteristics, ICP-MS is considered a mature technique that requires strict quality control.

ICP-MS is used in both primary and secondary tissue analysis. It can also be used to analyze inorganic nanoparticles. The technique has shown promising results for simultaneous determination of the concentration and size of inorganic nanoparticles in environmental and food samples.

Single-particle ICP-MS is also capable of detecting single-element elements in a single sample. It has a high degree of sensitivity, and it can also distinguish between particulate and ionic forms of analyte.

ICP-MS has numerous applications, and is one of the fastest growing trace element techniques. It was first commercialized in 1983, and today, over 16,000 systems are installed worldwide. This technology is used for industrial, pharmaceutical, environmental, and nuclear applications.

ICP-MS is the fastest elemental analysis technique available today. It can detect almost every element in the periodic table in parts per billion concentrations. This technology works by passing small amounts of material into plasma, which operates at approximately 8000 degrees Celsius. The plasma is then cooled and a mass spectrometer separates the sample ions according to their mass/charge ratio.

Atomic absorption spectroscopy

Atomic absorption spectroscopy (AAS) is another analytical technique used in this field. The technique is suitable for identifying and determining the concentrations of several metals. Table 3 provides examples of samples that are analyzed using AAS. Lead and cadmium are among the metals that have been determined in this way.

Atomic absorption spectroscopy is a technique that uses light to determine the concentration of specific metal atoms in a liquid or solid. The light is excited by a specific wavelength and the atoms in the sample absorb energy. The amount of energy absorbed is proportional to the number of atoms in the sample. The sample is then compared to a standard solution to determine the concentration of the element.

methods for heavy metal analysis

The advantages of AAS over classical gravimetric methods include increased sensitivity and selectivity. This technique has many applications in mining, oceanographic studies, drinking water, and soil analysis. There are also various types of spectroscopy used in the pharmaceutical industry.  An AAS is used to determine the concentration of contaminants in soils and other materials.

Atomic absorption spectroscopy is also used in clinical samples. This technique can determine the concentrations of various materials in human muscle, liver, hair, and brain tissue. It can also help determine the levels of mercury in fish. Mercury is an extremely toxic element that can build up in the environment and pose a risk to the food chain.

Methods to analyze heavy metals

Determining the level of metals in the environment is essential in creating an action plan to help mitigate their presence. Methods of heavy metal analysis are a major part of environmental pollution control. They can help ensure that toxic metals are not present in drinking water and are a reliable indicator for pollution prevention. Methods to analyze metals are widely used for monitoring the presence of heavy metals in a wide range of samples, from soil to solid waste.

The first step is to identify the metals that are present in a particular sample. This will determine their concentration. Using inter-element analysis, these metals are compared with the levels in waste water. If the correlations are high, the source of the heavy metals is likely to be anthropogenic.

Why You Should Work Towards an Energy-Efficient Home?

  By | | , ,
4 Comments

An energy-efficient home is something we should all work towards. It will save you money, decrease your carbon footprint, and make your home and lifestyle more environmentally friendly. Most of us think that achieving an energy-efficient home is difficult, expensive, and time-consuming, but it doesn’t have to be. There are so many little things we can do to decrease the amount of energy we waste and to reduce the amount of money we spend on running our homes. Today, we will be taking a look at what you can do to improve the energy efficiency of your home and why this will benefit you in the long run.

Upgrade Appliances

If your home appliances are old, chances are they are not very energy efficient and will be costing you more than they should to run. When you purchase any new appliance, you should look for one that comes with a stamp of approval, also known as an ‘Energy Star’ rating. This means the new appliance is classed as energy-efficient, which means you will save money on energy bills in the future.

Check Boiler Efficiency

In most UK households, the cost of running a boiler will be more than all of the other home appliances combined. To ensure that you aren’t spending too much on your boiler, you should assess its efficiency levels. There are simple tools you can use to do this. If you are spending too much, replacing a boiler is an option, but it’s expensive. Instead, you can look into cheaper ways of improving its efficiency. It is also important to get your boiler serviced annually in order to get the most out of your boiler without compromising on its efficiency.

Install Insulation

Energy that should be heating your home will be lost through your windows and doors when your home is poorly insulated. If your home is properly insulated, you will pay less to heat your home because the building will retain the heat more efficiently. It doesn’t cost too much to do and the money you spend on it will be made back over a couple of years through reduced energy costs.

Switch Energy Supplier

Some energy suppliers are greener than others, and many of the more sustainable ones also offer surprisingly cheap tariffs. By using an energy comparison website you should be able to find a new supplier that can improve your household’s carbon footprint while also lowering your household bills.

Use Renewables

Renewable energy comes from a resource that is naturally replaced on a human timescale. This includes wind, sunlight, waves, tides, rain, and geothermal heat. Using renewable energy is a great way to help the environment and to save money on energy bills. It can be expensive to install, but it comes with many benefits for you, your home, and the environment.

As you can see, the main reason many of us should choose to have a more energy-efficient home is to save us money, but it helps the environment too. We are all aware of the changes taking place in our environment, so protecting it and saving money while doing so is an offer we shouldn’t refuse.

For some people, the whole thing of “going green” is a trend, but in the world of construction, “going green” is definitely no trend… In fact, it’s a sustainable building practice that’s here to stay. As more cities adopt greener building regulations for new construction, contractors and construction companies alike are going to face the challenge of keeping up with these sustainable building practices.

One of the biggest areas in construction that greener changes need to happen in is construction waste. They say, “waste not, want not,”… well, in the world of construction, “when you waste less, you spend less.” Sustainable building practices, in the form of minimizing waste, means you’re not only building better, energy-efficient buildings but you’re also saving time and money on all your construction projects.

It’s just amazing to look at how the industry has changed over the years. True enough, certain things haven’t changed like state and industry-specific certifications and licenses… If you live in Oregon, you would still need to meet the Oregon continuing education requirements. But as far as sustainable practices, it’s amazing how more and more people are becoming conscious about reducing their carbon footprint to make the environment a better place… Back in the early 1940s to the 1960s, people could have cared less about their environmental impact.

But we are indeed in different times, and the construction industry is doing its part to implement green practices, including reducing construction waste. Here’s how construction companies and contractors are doing their part.

Effective Ways to Minimize Your Construction Waste

1. Avoid Creating Waste in the First Place

To truly manage your construction waste effectively, you should avoid creating it in the first place. Taking steps like taking exact measurements to ensure you have enough materials to build without any unnecessary leftovers is going to help tremendously. Conducting regular inventory checks will prevent you from overordering materials that you already have.

Additionally, properly training your team and educating them on the importance of construction waste management will help them to implement greener practices within their own job responsibilities.

2. Store Your Materials Properly

With construction sites, you’re not always going to be able to haul your materials in and out of a proper storage area; sometimes your materials have to set out on the site. But that also doesn’t mean your materials have to be ruined. You have to first and foremost, secure your site to minimize damage and even theft.

For example, you can store lumber on blocking and make sure to cover it up to prevent any damages. You want to do the same with brick and other masonry. The main thing is that your materials are a huge investment and you need to do all you can to protect your investment.

According to the National Equipment Register, states that have a large economy percentage in agriculture and construction industries are the biggest targets for thieves, and the most common pieces of equipment to steal include valuable pieces that are easy to move, like tractors, mowers, and other tools. Heavier pieces like bulldozers and backhoes aren’t so common because they’re too difficult to move.

3. Add Organization to Your Construction Site

Construction sites seem like they can be a bit chaotic, which they can, but they don’t have to be by simply adding a little organization to your site. Consider separating your recyclable and salvageable materials together in an area to reduce confusion; this just puts everyone on the same page. When your site is organized and your team knows where everything is, it will cause you to spend less money on unnecessary materials, re-doing work, and sorting in the middle of a project.

4. Recycle and Re-Use Your Salvageable Materials

On all of your construction sites, make it a point to recycle materials like paper, plastic, metal, and glass… wood too. In that same token, also make sure that if there’s a way to reduce any costs in construction projects, re-using your salvaged materials is the way to do it. The purpose is to reuse these materials so that they don’t end up in a landfill somewhere… You can’t always avoid waste on all projects but landfills are one of the worst ways to handle your construction site waste.
