How Can Oil-Free Air Compressors Benefit You and The Environment?

If you already have an air compressor, you will be aware of how they are an incredibly valuable tool for industries and DIY enthusiasts. Commonly used to power pneumatic tools but can be used for a variety of applications. Air compressors provide you with complete power over spraying, nailing, sanding and hammering at a fraction of the time it would take with manual tools.

These machines can also be used for inflating tyres, auto repairs and even creating home-made snow machines. Sandblasters, impact wrenches, grease guns, die grinders and angle disc grindles can also be attached.

We all love our power tools and would be lost without them; however, we are becoming more aware regarding the issue of carbon emissions. Reducing our carbon footprint is one of the most important things companies and individuals can do in their lifetime. Small changes within your business and homes can be a great start to decrease our carbon emissions and help save the planet.

If you are looking to purchase your first air compressor or to update an existing model, Direct Air has created a guide on why an oil-free air compressor is a great choice, not just for the environment, but to help you save on energy bills. You can see their full range of oil-free air compressors at https://www.directair.co.uk/products/oil-free-air-compressors/.

Every air compressor requires lubrication in order to efficiently and safely draw in air to its cylinder, commonly using a piston movement. The traditional method to achieve this is using oil, while oil-based air compressors do have their benefits as they are more robust and can handle large-scale applications, they are higher in initial cost, harder to maintain and far heavier than their oil-free counterparts.

Oil-free air compressors gain lubrication through a non-stick coating, generally Teflon. As extra elements to hold oil are eradicated from these machines, they are far lighter and smaller than oil-based air compressors which make them ideal for applications that are not static. Due to less components, oil-free air compressors are often cheaper to purchase.

Oil-based air compressors must remain static and upright when in use, oil-free are far more versatile. As you do not need to consider the oil flow, they can be positioned wherever you see fit. They are also operatable at any temperature, oil can become viscous in cooler climates and can cause problems when attempted to start the motor, oil-free erases this issue.

With these benefits in mind, you can achieve even more with your oil-free air compressor by helping to reduce the use of fossil fuels maintain the planet’s natural resources. You can also make a direct impact on your running costs, saving you and your business money on your energy bills.

With an oil-free air compressor, all costs to collect and dispose of oil-laden condensate will be removed, not to mention the initial cost of the oil itself. These compressors are less wasteful as they do not require the replacement of the air/oil separator and filtration elements which are required to get rid of oil aerosols, these parts are notorious for wearing down quickly. You will not needlessly be sending these parts to landfill and be bearing the cost of new ones on a regular basis.

If you are worried about direct harmful emissions from your air compressor, oil-free air compressors produce the purest form of air which will reduce any negative impact into the atmosphere, great for the planet and for those working around it. You will also not have the trouble of potentially contaminated products from oil spillages during projects.

A big bonus of oil-free air compressors is that they are safer than their counterparts, as there is no oil, you eliminate the risk of compressed air pipeline fires. An incredibly important factor to consider for the safety of you, your staff and your premises.

Oil-free air compressors can dramatically reduce your energy bills compared to the oil-based counterpart as they require less energy to run which will cut down your environmental impact. Oil-free air compressors do not need increased forces of power when the unit has a drop in the filtration in the downstream pressure, unlike oil-based. Oil-free units can, on average, unload in 2 seconds of your command which only uses around 18% of its full load horsepower.

Of course, all machines come with their downsides and oil-free air compressors are no exception. Oil-free air compressors are known to generate more noise which can be an annoyance and hazard to those using it and those around them.

There is a solution, you can invest in a low-noise air compressor. These reduce noise levels to around 40dB. The lowest safe level is considered 60 dB and anything over 80dB can cause long-term problems with hearing.

With the addition of an acoustic cylinder to contain this noise, opting for a low-noise air compressor is an investment worth making. It is recommended when using any power tool that protective gear is worn to eliminate lasting damage and long-term effects, even with a low-noise machine.

If you were considering purchasing a new air compressor or have simply been doing research on them, you should now have a comprehensive understanding of the benefits an oil-free air compressor possesses.

Your Choices for Alternative Energy

While using alternative sources of energy is a right way for you to save money on your heating and cooling bills, it also allows you to contribute in vital ways to both the environment and the economy.  Alternative energy sources are renewable, environmentally sustainable sources that do not create any by-products that are released into the atmosphere like coal and fossil fuels do.

Burning coal to produce electricity releases particulates and substances such as mercury, arsenic, sulfur and carbon monoxide into the air, all of which can cause health problems in humans.

Other by-products from burning coal are acid rain, sludge run-off and heated water that is released back into the rivers and lakes nearby the coal-fired plants.  While efforts are being made to create “clean coal,” businesses have been reluctant to use the technology due to the high costs associated with changing their plants.

If you are considering taking the plunge and switching to a renewable energy source to save money on your electric and heating bills or to help the environment, you have a lot of decisions to make. The first decision you need to make is which energy source to use in your home or business.  Do you want to switch to solar energy, wind power, biomass energy or geothermal energy?

Emissions from homes using heating oil, vehicles, and electricity produced from fossil fuels also pollute the air and contribute to the number of greenhouse gases that are in the atmosphere and depleting the ozone layer.  Carbon dioxide is one of the gases that is released into the air by the burning of fossil fuels to create energy and in the use of motor vehicles.  Neither coal nor fossil fuels are sources of renewable energy.

Replacing those energy sources with solar, biomass or wind-powered generators will allow homes and businesses to have an adequate source of energy always at hand.  While converting to these systems can sometimes be expensive, the costs are quickly coming down, and they pay for themselves in just a few short years because they supply energy that is virtually free.  In some cases, the excess energy they create can be bought from the business or the homeowner.

While there are more than these three alternative energy options, these are the easiest to implement on an individual basis.  Other sources of alternative energy, for instance, nuclear power, hydroelectric power, and natural gas require a primary power source for the heat so it can be fed to your home or business.  Solar, wind, biomass and geothermal energy can all have power sources in your home or business to supply your needs.

Solar Energy

Solar power is probably the most widely used source of these options.  While it can be expensive to convert your home or business over to solar energy, or to an alternative energy source for that matter, it is probably the most natural source to turn over to.  You can use the sun’s energy to power your home or business and heat water.  It can be used to passively heat or light up your rooms as well just by opening up your shades.

Wind Power

You need your wind turbine to power your home or office, but wind energy has been used for centuries to pump water or for commercial purposes, like grinding grain into flour.  While many countries have wind farms to produce energy on a full-scale basis, you can have your wind turbine at home or at your business to provide electricity for your purposes.

The cost of alternative energy systems has dropped sharply in recent years

Biomass Energy

Biomass energy has rapidly become a vital part of the global renewable energy mix and account for an ever-growing share of electric capacity added worldwide. Biomass is the material derived from plants that use sunlight to grow which include plant and animal material such as wood from forests, material left over from agricultural and forestry processes, and organic industrial, human and animal wastes. Biomass comes from a variety of sources which include wood from natural forests and woodlands, agricultural residues, agro-industrial wastes, animal wastes, industrial wastewater, municipal sewage and municipal solid wastes.

Geothermal Energy

A heat pump helps cool or heat your home or office using the earth’s heat to provide the power needed to heat the liquid that is run through the system to either heat your home in the winter or cool it off in the summer.  While many people use it, it doesn’t provide electricity, so you still need an energy source for that.

Newly-Launched Inventions That Can Help Homeowners Save Energy

Domestic energy efficiency has advanced a long way over the last few decades. Despite our overall energy consumption increasing by just over a third since 1980, on average our homes consume around 10% less overall. How can this be the case when we have so many more electrical appliances? Back in 1980, not many homes had more than a single TV, and computers and mobile phones were essentially non-existent. Yet somehow they used more electricity!

The answer to this question comes down to one simple principle. Energy efficiency. Government regulations and technical advances led by the private sector have resulted in appliances that are simply more sustainable. Throw in a better public understanding of the importance of reducing carbon emissions, and also the use of money expert comparison sites to track the expense of powering a home, and it the picture becomes a little clearer.

Expect to see this trend become ever more prevalent in the near future, as sustainability has become a huge industry sector that continues to rapidly expand.

Here’s a selection of the most recent technologies that are already helping homeowners save money that we can expect to become common place over the coming years.

1. Smart Homes

At first glance, you may wonder what the point is in buying a new domestic appliance that is advertised as ‘internet connected/ready’. After all, who is going to need a web compatible refrigerator or air conditioning unit? It is increasingly common for newly released appliances to boast this feature because in the coming years, our homes are going to be much more connected than at present. Being able to monitor and control energy expenditure remotely via smartphone is a tech that is already with us – but these are still the early days.

The next big step forward is going to be the implementation of wireless sensors throughout the home. These will connect all the appliances in the home to a centralized control panel which will automatically instruct how they interact with the energy supply.

For instance, appliances not in use, but on ‘standby’ mode will be entirely disconnected from the power supply when nobody is at home. Heating and air conditioning use will be precisely measured according to the ambient temperature. Just these two examples – and there are many more in the pipeline – are set to shave a considerable amount of household energy consumption in the very near future.

2. Next Generation Home Insulation

The US Industrial Science & Technology Network takes the approach that heating and cooling costs can best be reduced by simply developing superior insulation. While still at the development stage, these are promised to be far more efficient at preventing heat from escaping.

As may be expected, they are also going to be environmentally sound and most likely comprised of recycled foam materials. Should these be proven to work, there is a very good chance they will become the industry norm for new build and redeveloped housing in the years to come.

3. Reflective Roofing Materials

While insulation is ideal for maintaining an ambient temperature what about those who live in warmer climes? Everyone knows how expensive it is to run air conditioning 24 hours a day, but there have been considerable recent advances in reflective rooftop materials. Currently, these work by using special pigments that are coated onto the roof in order to reflect sunlight and heat.

The next generation in development will use fluorescent pigments that look likely to be up to four times more efficient. So for those who reside in areas where effective air conditioning is essential around the year, these new materials may well be an absolute godsend.

4. Magnetocaloric Refrigerators

A fridge powered by magnets? Close, but not quite. Refrigeration technology has barely changed or advanced since they were first introduced. Modern fridges still rely on vapor compression, which unfortunately requires chemical coolants that are notoriously bad for the environment.

Next generation models are going to be able to make use of water-based coolants that make use of the magnetocaloric effect. In layperson’s terms, this is the use of magnets to alter the magnetic field which can provide an extremely energy efficient cooling effect. Expect this to become commonplace in the coming years, thanks to their potential in enormously reducing energy expenditure and carbon emissions.

5. Much More Efficient Heat Pumps

Considerable progress has been made by the US Building Technologies Office in developing heat pumps that essentially move heat throughout the home. There are three models in design that promise to considerably reduce expenditure on heating while also significantly reduce carbon emissions. Standard gas boilers/furnaces are notoriously expensive and inefficient.

  • A low-cost gas-based heating pump could massively increase efficiency and result in lowering heating costs by a staggering 45%.
  • Multiple function fuel based pumps designed for domestic use can still save an estimated 30% with the added bonus of also providing more efficient water heating.
  • Natural gas based heating pumps connected with air conditioners aim to use a very low emission boiler to cater for all domestic needs regardless of the season. Of all three options, this is the most complete package and the one most likely to become widespread in the coming years.

These styles of heat pumps are also going to be used to significantly reduce the energy used by clothes drying machines. General Electric has been already near completing their first gas pump compatible dryer. This is intended to reduce the energy consumption of perhaps the least efficient appliance in the home by up to 60%.

6. Even Better LED Lighting

Energy saving lighting may have become the accepted norm in many households, and the good news is that it is set to become even better. At present these are up to 85% more efficient than old fashioned incandescent bulbs, but the next generation – scheduled for a few years time – promise to double their efficiency. An improvement up to 230 lumens (from the current 115) is forecast.

8% of all electricity consumption in the USA are due to lighting homes and businesses. Having that figure will make for a huge national saving and reduction of energy costs across the board. (Source:https://www.eia.gov/tools/faqs/faq.php?id=99&t=3)

7. Advanced Window Insulation

While still in development this may not sound like a huge advance, but could well result in enormous net energy savings down the line. Using microprocessors and sensors to measure sunlight and radiant heat, these are going to automatically provide shading to assist with providing ideal natural lighting and also assist with heating. Expect these to be integrated with the general smart home system outlined above in due course.

Final Thoughts

So there we have seven of the most exciting and interesting developments that we can expect to see in the home over the coming years. While some are already in production while others are just passing the prototype phase, the future is looking positive in terms of reducing emissions and better managing energy consumption. Energy efficiency is here to stay and these developments will likely only be the tip of the iceberg compared to what we can look forward to over coming decades.

Green Ways to Travel the Globe

According to a recent report, 87% of travelers want to travel more sustainably, but only 39% say that they accomplish the task on most or all occasions. Well, in a world that often focuses so heavily on comfort and convenience, it’s understandable. Many cultures and individuals are certainly making great efforts to lead eco-friendly lives, but many are still left wondering how to make those changes. Read on to explore a wide array of green ways to travel the globe.

Where You Go

Carefully choose your destination. Shorter distances without air travel are ideal, but obviously, that’s not always possible. So, if you’re planning to travel a little further, look into visiting destinations that value sustainability as well. It will be easier if the surrounding culture has the same eco-goals.

Places like Amsterdam are great because they do not rely heavily on vehicular transportation. They stick to bikes and their own two feet most of the time which makes a huge difference. Additionally, make sure that you’re not visiting a destination that is already overwhelmed with tourists and travelers to the point of causing harm. You don’t want to be a part of the problem.

How You Get There

It’s no secret that air travel is a unideal form of transportation right now, but since it is often unavoidable, there are a few small things that can help. First, do your research and choose the most fuel-efficient airline. When you do, book a non-stop, flight and sit economy.

A significant portion of a flight’s emissions is during take-off and landing, and business select or first class is responsible for three times more emissions than economy seating. And in preparation, pack lightly because an aircraft burns more fuel when it is carrying a heavier weight.

But, if you can avoid flying, go for a relaxing train ride. Traveling by train is widely popular in places like Europe and in the United States, you can make it the highlight of your journey.  If you need to rent a car, you can check eco friendly car rental is before you book.

Where You Stay

Look for accommodations that prioritize sustainability. Do your research and look for places that have certifications from a third party, like the Global Sustainable Tourism Council or the Rainforest Alliance. It doesn’t mean that you won’t have the amenities that you may want or need, it just means that they abide by a particular set of global standards that aim for a more “green” operation.

Parting Shot

Even if you aren’t able to choose the ideal location, avoid air travel, or stay at a certifiably eco-friendly hotel, don’t worry. There is still plenty that you can do to lighten the load. Support the local economy, bring a reusable water bottle, carry a rain jacket, take shorter showers and go for ecotourism. Just do the best that you can, and you’ll be on the right track.

Clean Cookstoves: An Urgent Necessity

Globally, three billion people in the developing nations are solely dependent on burning firewood, crop residues, animal manure etc for preparing their daily meals on open fires, mud or clay stoves or simply on three rocks strategically placed to balance a cooking vessel.  The temperature of these fires are lower and produce inefficient burning that results in black carbon and other short-lived but high impact pollutants.

These short-lived pollutants not only affect the persons in the immediate area but also contribute much harmful gases more potent than carbon dioxide and methane. For the people in the immediate area, their health is severely hampered as this indoor or domestic air pollution results in significantly higher risks of pneumonia and chronic bronchitis.

To remedy the indoor air pollution (IAP) and health-related issues as well as the environmental pollution in the developing world, clean cookstoves are the way to advance. But to empower rural users to embrace the advanced cookstoves, and achieve sustainable success requires a level of socio-cultural and economic awareness that is related directly to this marginalized group. The solution needs to be appropriate for the style of cooking of the group which means one stove model will not suit or meet the needs and requirements of all developing nation people groups.

Clean cookstoves can significantly reduce health problems caused by indoor air pollution in rural areas

Consideration for such issues as stove top and front loading stove cooking, single pot and double pot cooking, size of the typical cooking vessel and the style of cooking are all pieces of information needed to complete the picture.  Historically, natural draft systems were devised to aid the combustion or burning of the fuels, however, forced draft stoves tend to burn cleaner with better health and environmental benefits. Regardless of cookstove design, the components need to be either made locally or at least available locally so that the long term life of the stove is maintainable and so sustainable.

Now, if the cookstove unit can by powered by  simple solar or biomass system, this will change the whole nature of the life style and domestic duties of the chief cook and the young siblings who are typically charged with collecting the natural firewood to meet the cooking requirement.

Therefore the cookstoves need to be designed and adapted for the people group and their traditional cooking habits, and not in the reverse order. To assess the overall performance of the green cooking stoves requires simple but effective measures of the air quality. The two elements that need to be measured are the black carbon emissions and the temperature of the cooking device.  This can be achieved by miniature aerosol samplers and temperature sensors. The data collected needs to be transmitted in real-time via mobile phones for verification of performance rates.  This is to provide verifiable data in a cost effective monitoring process.

4 Reasons Why LED Lights are Saving the Earth

Saving the Earth is on top of the list of most product designers these days. On a daily basis, we contribute to global pollution. From our homes to our jobs, lighting is a big factor in our everyday life. Our goal is to find life-changing ways to save Mother Earth from destruction.

Let’s start in places we usually go to like the house, office, restaurants, and malls. One of the factors contributing to environmental pollution is lighting materials. Most lighting materials increase the consuming of carbon footprint and chlorofluorocarbon. With the advancement of technology comes the birth of LED (Low Emitting Diode). It is the next big thing when it comes to interior and exterior architecture without compromising the Earth’s current state.

With these in mind, we have four convincing reasons why LED lights are saving the Earth.

Made of Non-toxic Materials

Unlike incandescent and other traditional lights, LED lights are made of non-toxic materials. This does not just affect the environment but as well as its users. LED lights are carefully manufactured with the idea that it frees the Earth from contamination and pollution. Efficient disposal is also what makes it environment-friendly. It alleviates the toxic waste produced by the material composition of traditional lighting.

LED lights are established to lower the environmental impact of lighting. The absence of mercury makes it easier to use and to dispose of. Traditional lighting can produce a toxic gas which can harm both the environment and the people.

Moreover, LED lights sold in the market is a big step to the people they cater to. They do not contribute to the increase in temperature because they don’t produce ultraviolet rays. Their excessive heat and vibrancy can cause a hazard to our environment.

Durable Lighting Design

What we loved the most about LED lights is their durable design. On average, an LED bulb can last from 10 to 15 years. Their lifespan is six times more than a traditional bulb. Even after a decade, the vibrancy of the light is maintained regardless of the daily usage. Since it’s energy efficient, it reduces the number of times required for replacing your lights. The longer lifespan offered by LED lights results to lower carbon emissions.

The durable lighting design of LED lights ensures the safety of the Earth. Lowered number of replacements mean lowered costs in purchasing, delivery, and installation of lights. In line with this, you get to minimize the waste product produced by your home or establishment. The composition of LED lights promotes the efficiency of utilization and disposal. Even at the last second, you get the best value for your money without compromising the safety of the Earth

Comes in Different Variants

Apart from the amazing specifications of LED lights, they come in different shapes and sizes too. The birth of LED lights introduced the art of lighting. Some light variants feature different colors and vibrancy you can play in just a click away. Smartphones and remotes are used to take control. Moreover, LEDs are more than just bulbs. They come in different types too. Bulbs, floodlights, decorative, strip, and downlights are what the LED light family is comprised of.

With these features, you can choose the best LED lights depending on utilization. Some can work indoors, outdoors, and some can be used in both. They are considered as a piece of unique lighting equipment because it gives you the ability to be creative with lighting design. You can use it for home and establishments’ to promote its atmosphere. These lights are commonly found in factories, restaurants, offices, streets, hotels, and walkways.

Energy-efficient Lighting

On average, you can save up to 90% of electricity costs with LED lights. Unlike traditional lighting, they are an economical choice. Their lighting capability will not require you to fill the room with a number of lights. LED lights are the best example of direct lighting. Lesser number of lights are required to give you the same amount of lighting as traditional lights. There is no energy wasted because it is capable of emitting lights in all directions.

Using LED lights are ideal especially for office buildings and factories. Since they light a bigger space, they save a bigger percentage designated for electricity. LED lights convert 95% of their consumed energy into light and 5% into heat. They will give you the same amount of light as traditional lights with 36 watts consumed. This is a big help to the environment considering that they will demand less energy from power plants and fewer greenhouse gases emitted.

Promotes Productivity

LED lights have different benefits for their users. They the ability to promote productivity since the lights give you a cool relieving feeling compared to incandescent. These lights enhance your sense of concentration and energy. Incandescent lights, on the contrary, give you a warm and lazy atmosphere. The heat they produce tends to make you feel cozy. That is why most occupational buildings switch to LED lights to give the employees a sense of focus.

Conclusion

Switching to LED lights alleviate the demand and pressure on the resources of the Earth. We save money and energy from using these and at the same time, we are saving our environment. Knowing that the quality and brightness are not compromised, it’s an economical choice to make. Use these 4 reasons as an eye-opener on why you should switch to LED lights!

Where Are All the Electric Vans?

The USA is way behind Europe when it comes to electric vehicles, with sales in Europe exceeding 1 million in 2018, while US figures stood at just 750,000. This is despite the giants of Silicon Valley, including Google, Amazon and Tesla, all making strides to offer electric vehicles to the mass market. The area where the contrast is most clear is in regards to vans. While Europe has many on offer, electric vans are almost non-existent on American roads. Where does this leave commercial enterprises looking to cut their carbon emissions?

Europe Leading the Way

Although hardly the norm, it isn’t uncommon to see fully electric commercial vehicles on European streets. German based DHL are selling over 5000 StreetScooters a year, allowing companies to offer battery powered deliveries. Meanwhile, the UK’s best selling plug in van is the Nissan e-NV200. This attractive commercial vehicle is on sale throughout Europe, selling more than 4000 a year. Unfortunately, it is not available in the US.

If you are a businessman looking to cut fossil fuel usage, while driving a commercial vehicle, then you may be better off moving to Europe. Greenhouse gases in the continent fell 22% between 1990 and 2016. The USA is struggling to keep up with the switch to renewable energy sources.

Is Tesla the Only Game in Town?

Don’t worry – it isn’t all bad news for the USA. With companies like Tesla offering their own electric pickup and semi vehicles, there could be a shift in sale trends soon. However, neither of these vehicles are yet to hit the mass market. Other electric truck or van options are few and far between. The likes of Google are focusing their efforts on creating self-drive vehicles rather than venturing into commercial electric automobiles that are wheelchair accessible as well.. 

Other Ways to Cut Carbon Emissions

Keep searching for the perfect electric van for your company. If Europe has them, then you can find one in America. In the meantime, however, consider other ways to cut your carbon footprint. For the running of any electronics, invest in solar power. This has really taken off in the USA and is one of the cheapest options available. You should also try to source products locally and remove plastic packaging from your goods.

Electric vehicles really can’t arrive soon enough, but commercial vans and trucks are yet to become mainstream. The USA needs to take a leaf out of Europe’s book and invest in electric vans. In the meantime, consider switching to solar power and taking other steps to reduce your company’s carbon emissions.

Obstacles in Implementation of Waste-to-Energy

The biggest obstacle to the implementation of Waste-to-Energy (or WTE) lies not in the technology itself but in the acceptance of citizens. Citizens who are environmentally minded but lack awareness of the current status of waste-to-energy bring up concerns of environmental justice and organize around this. They view WTE as ‘dumping’ of pollutants on lower strata of society and their emotional critique rooted in the hope for environmental justice tends to move democracy.

An advocate of public understanding of science, Shawn Lawrence Otto regrets that the facts are not able to hold the same sway. Some US liberal groups such as the Center for American Progress are beginning to realize that the times and science have changed. It will take more consensus on the science and the go ahead from environmental groups before the conversation moves forward, seemingly improbable but not without precedent.

Spittelau Waste-to-Energy Plant

The Spittelau waste-to-energy plant is an example of opposition coming together in consensus over WTE. It was built in Vienna in 1971 with the purpose of addressing district heating and waste management issues. Much later awareness of the risks of dioxins emitted by such plants grew and the people’s faith in the technology was called into question. It also became a political issue whereby opposition parties challenged the mayor on the suitability of the plant. The economic interests of landfill owners also lay in the shutting down of the WTE facility. The alternative was to retrofit the same plant with advanced technology that would remove the dioxins through Selective Catalytic Reduction (SCR).

Through public discussions it appeared that the majority of the people were against the plant altogether though thorough studies by informed researchers showed that the science backs WTE. The mayor, Helmut Zilk eventually consulted Green Party members on how to make this technology better perceived in the eyes of the people, and asked the famous Austrian artist Freidensreich Hundertwasser, who was a green party member to design the look of the plant. Freidensreich Hundertwasser after carefully studying the subject wrote a letter of support, stating his belief as to why WTE was needed and accepted Mayor Helmut Zilk’s request. Later public opinion polls showed that there were a majority of people who were either in favor of or not opinionated about the plant, with only 3% in outright opposition of the plant.

Polarized Discussion

Waste-to-Energy or recycling has kept public discourse from questioning whether there may not be intermediate or case specific solutions. This polarization serves to move the conversation nowhere. For now it can be agreed that landfills are devastating in their contribution to Climate Change and must be done away with. The choice then, of treatment processes for municipal solid waste are plentiful. If after recovery of recyclable materials there remains a sizeable waste stream the option of waste-to-energy can be explored.

Primary Considerations

  • Environmental implications (i.e. CO2 emissions vis-à-vis the next best fuel source) given the composition of the local waste stream. If the waste stream consists of a high percentage of recyclables the more sustainable waste strategy would be to ramp up recycling efforts rather than to adopt WTE,
  • Likely composition and variation of the waste stream and the feasibility of the technology to handle such a waste stream,
  • Financial considerations with regards to the revenue stream from the WTE facility and its long term viability,
  • Efforts at making citizens aware of the high standards achieved by this technology in order to secure their approval.

Bioenergy with Carbon Capture and Storage: Role in Climate Mitigation

With increasing concern and awareness of climate change, there has been a growth in the renewable energy sector through government subsidies and private investment, allowing for the replacement of current sources of energy with less carbon-intensive fuels. However, renewable energy technologies are yet to topple the traditional fossil fuel-powered electricity market. With the increasing trajectory of global emissions, climate research has been exploring other methods of climate mitigation, for instance, through the use of large-scale geoengineering technologies.

Biomass-Resources

A quick glance at popular biomass resources

Of particular focus are the carbon dioxide removal techniques, namely Carbon Capture and Storage (CCS) and Bioenergy with Carbon Capture and Storage (BECCS) that have been prominently featured in emission scenarios of climate models, particularly for their direct influence in reducing carbon dioxide emissions. CCS involves capturing carbon dioxide emissions from industries and storing them under geological reservoirs either on shore or offshore. You can read more about this technology on a previous EcoMENA article.

What is Bioenergy with Carbon Capture and Storage

One of the main concerns about CCS is the use of fossil fuels for its operations. In the pursuit for greener climate mitigation technologies, Bioenergy with Carbon Capture and Storage (BECCS) has emerged as a climate saviour, featuring in prominent emissions scenarios and climate models to achieve the 1.5-degree target.

In the place of fossil fuels, biomass is instead used as the primary fuel source for BECCS as seen in the picture below. The two-step absorption of carbon dioxide, first during the growth of the biomass, and second through capturing of the biomass emissions, makes BECCS, in theory, a net negative emissions technique.

Source: Can we deploy enough BECCS to achieve climate targets? AVOID 2

Of the 116 climate scenarios suggested by the IPCC, BECCS was seen to have a significant role in 101 of the scenarios to help prevent global temperature rise above the 1.5-degree target. In fact, UK electricity generator Drax, has chosen to invest in the BECCS technology and started its first trial earlier this year, making it the first of its kind in Europe.

Risks associated with BECCS

While the combination of bioenergy and CCS provides an ideal carbon negative mitigation strategy, it also combines the existing risks associated with both technologies. In addition to lack of investment and long-term economic policies for CCS, large scale deployment of BECCS is hindered by uncertainties such as land, water and resource availability. Studies have shown concerns regarding the carbon intensity and the scale of land and resources required to sustain the bioenergy component required for BECCS.

While the net negative aspect of BECCS may work in theory, studies have revealed significant proportions of emissions associated with indirect land use change for biomass production for BECCS. In addition to technical challenges, one of the key constraints for the deployment of such climate technologies is social acceptance, where sections of the general public, or specific stakeholders, remain unconvinced with certain aspects of the technology due to ethical or political reasons.

Conclusion

As such, while CCS and BECCS may offer the ideal climate saviour solution to reduce overall carbon dioxide emissions, the technologies are still overcast with various technical and social challenges that limit their commercial usage for climate mitigation.

How Artificial Intelligence is Saving Our Planet

It takes a high level of data analysis to predict the effects of climate change and the implications of our actions to stop and adapt to it. Often, scientists have terabytes of data, but not the computing power to make sense of climate issues like hurricanes. But this level of analysis is possible with artificial intelligence (AI). In fact, AI may be the best weapon we have to combat and adapt to the effects of climate change. That’s because it can analyze large chunks of data from past events and make accurate predictions about future ones.

Today, AI is helping to monitor and predict everything from glacier retreat to commercial waste management. As innovations in “deep learning” march on, AI’s prescience will help inform scientists about climate impacts and policymakers on the most prudent steps for adaptation. Here are some critical ways AI is helping to preserve our planet.

Smarter Home Energy Use

AI is helping save the planet by assisting homeowners through energy-efficient smart homes. The Internet of Things and today’s “smart devices” let homeowners control their energy use and lower their monthly bills. Smart thermostats can adjust temperature settings for specific rooms in a house. Smart water sprinklers can change water usage based on weather forecasts. And smart security systems can cut down on false alarms calls — so fewer gas-guzzling trips by first responders. The automation, connection, and prediction power built into these smart devices allow homeowners to lower their carbon footprint.

But smart energy use is not just about conservation — it’s also about the best time to use energy. Peak energy hours like evenings are higher-demand, higher-cost times. Smart devices can automate energy use for low-demand hours. Plus, off-peak times like mid-day are when alternative energy sources like solar and wind contribute the most. Therefore, smart technology promotes renewable energy.

Soil Conservation

Soil degradation is a problem often overlooked in the media. But it has serious consequences for humanity’s ability to adapt to and survive climate change. It takes a millennium to generate only three centimeters of topsoil, and soil degradation is happening at a much faster rate. Chemicals, deforestation, erosion, and global warming are major contributors to soil degradation. And if the current rate of degradation continues, the planet’s farmable land could disappear within 60 years, according to United Nations officials.

But farmers and scientists are using AI to help conserve the soil by marshaling complex algorithms along with robots and drones to detect erosion and monitor soil health. For example, one company has developed an agricultural app to help farmers identify nutrient deficiencies within their soil. And farmers are using machine learning to predict the best times to plant, irrigate, and harvest crops based on weather changes. Accurate predictions mean less need for pesticides and fertilizers, which degrade the soil.

Exploring and Protecting Oceans

Scientists watch and test the health of oceans because they’re the best indicators of Earth’s health. Microplastics, increased CO2 levels, and ocean acidification are changing the surface of the planet. The key to protecting oceans is exploring and monitoring them for changes. Climate scientists and oceanographers are using AI technology to drive autonomous marine vehicles to the deepest depths. And some companies are developing autonomous garbage collection systems that would help remove plastics and floating debris.

Another emerging technology — blockchain — is helping to track fishing and identify illegal behavior. Blockchain is the same technology that powers cryptocurrencies like Bitcoin. The technology acts as a transparent ledger for transactions. Blockchain is a decentralized system, which means it operates autonomously and isn’t subject to misuse and abuse. Trust is critical to international treaties that regulate fishing quotas and manage overfishing. Blockchain technology can record each fish (e.g., tuna) with a scannable code uploaded to the ledger. Therefore, retailers, customers, and regulators can confirm that fish are legally caught.

Air Pollution Detection

AI is becoming an invaluable tool for tracking our air quality and identifying sources of pollution. During accidental emissions, city air quality officials need to identify and respond quickly. Some European cities are using leak sensors and AI to help create emission maps, predict mortality rates, and estimate financial costs of emergency responses. These data points give decision makers a more accurate view of the air pollution along with more targeted remediation.

In addition to monitoring air pollution, AI is also cutting tailpipe emissions. AI manages self-driving cars to make getting from point A-to-B more efficient. Self-driving automobiles can cut oil consumption and greenhouse gas emissions by 2% to 4% annually. AI and global positioning systems operating driverless tractor-trailer rigs will make deliveries non-stop, faster, and less costly to the planet. Complex algorithms, sensors, and traffic lights are directing traffic flow in some cities. These systems are currently reducing travel time by 25%, braking by 30%, and idling time by 40%.

Evaluating the Efficacy of Action

AI is bringing powerful ways to monitor and predict threats to our environment. Synthetic thinking adds value for scientists, officials, and policymakers by giving them deeper looks into current environmental situations. Perhaps, more than anything, AI’s biggest potential lies in figuring out where solutions hit the mark and where they miss. It’s counterproductive to invest resources and time into bad solutions. But that’s highly likely, given the complexity of climate change and adaptation.

Where do we invest? Which coastline needs saving the most? What communities are at a higher risk? With dwindling resources and bigger dangers, we will face some hard decisions in the future about where to deploy our efforts. At some point, those decisions will mean life or death. We will need quick thinking and accurate data. Evaluating our options and predicting their implications is where AI will bring the most value.
