Think Waste as a Renewable Resource

Landfills produce renewable energy from waste.

When you think about renewable energy, what comes to mind? Perhaps you picture wind turbines, solar panels or the underground loops of geothermal systems. What you might overlook is a source derived from waste products – the stuff we discard every day.

If that’s the case, you’re not alone. Even though the Environmental Protection Agency (EPA) endorses landfill gas as a renewable source of energy, right up there with wind and solar, it’s not top-of-mind for most.

At Waste Management, we think about transforming waste materials into energy every single day. In fact, for decades we’ve applied science with creative thinking and problem-solving to derive value from waste.

We’re the largest landfill-gas-to-energy (LFGTE) developer and operator in North America. We operate 130 LFGTE projects at landfills across the country, and we generate enough energy – more than 4.6 million megawatt-hours per year of capacity – to power 460,000 homes.

The LFGTE process is proven, straightforward and efficient. An elaborate system of wells and pipes transports and processes landfill gas, which is a natural byproduct of waste decomposition. The gas is then filtered and compressed so it is usable as fuel. From there, it’s transported to a nearby facility where it powers a set of engines connected to an electrical grid, and sold to public utilities, municipal utilities and power cooperatives.

Think Renewable Natural Gas

Beyond power generation, we’re also a leader in converting landfill gas into clean natural gas fuels that can be distributed for residential, industrial and transportation use.

Renewable natural gas (RNG), or biomethane, is a pipeline-quality gas that is fully interchangeable with conventional natural gas and thus can be used in natural gas vehicles. RNG is essentially biogas (the gaseous product of the decomposition of organic matter) that has been processed to specific purity standards. Like conventional natural gas, RNG can be used as a transportation fuel in the form of compressed natural gas (CNG) or liquefied natural gas (LNG). LNG is natural gas in its purified and liquefied form.

In June 2018, we unveiled the latest addition to our RNG facilities at the Outer Loop Recycling and Disposal Facility in Louisville, Kentucky. Using state-of-the art technology, the facility captures methane and converts it to pipeline-quality natural gas. The Outer Loop facility produces enough RNG each day to fuel about 800 of our CNG collection trucks. 

We also operate two other RNG facilities. At the Milam Landfill in East St. Louis, Illinois, purified gas from the landfill is placed into the Ameren Illinois pipeline. The facility produces about 13,600 diesel gallon equivalents (DGE) per day of RNG, enough to fuel about 620 of our CNG collection trucks. At the American Landfill RNG Facility in Waynesburg, Ohio purified gas from the landfill is placed into the Dominion East Ohio pipeline. The facility produces about 3,600 diesel gallon equivalents (DGE) per day of RNG.

This year, we have two more RNG projects under development at the Skyline Landfill in Ferris, Texas, with completion scheduled for Q4 2019, and the Williamson County Landfill in Hutto, Texas, with completion scheduled for Q1 2020.

With Linde North America, WM pioneered our first facility to produce natural gas from landfill gas.  Our Altamont Landfill in Livermore, California, and has produced renewable liquefied natural gas (LNG) since 2009. Landfill gas at the Altamont Landfill is captured and converted into RNG. Our fleet of transfer trucks traveling between our Davis Street Transfer Station and the landfill are fueled exclusively with this renewable fuel! The facility creates 6,300 gallons per day of RNG or about 3,750 diesel gallon equivalents (DGE) per day, enough to fuel about 170 of our CNG collection trucks. 

Natural gas produced from landfill gas now fuels 32 percent of our natural gas trucks.

Think Solar

Back to our clean energy word association game. When you hear solar, do landfills come to mind? Well, they should, because the sizable geographic footprint of landfills and their proximity to existing infrastructure make them ideal locations for large-scale solar installation. 

The EPA recognizes and promotes the application of solar through its RE-Powering America’s Land initiative encouraging renewable energy development on contaminated lands, landfills and mine sites. At Waste Management’s closed L&D Landfill site in New Jersey, Public Service Electric and Gas Company (PSE&G) constructed one of the largest landfill-based solar farm projects in the country. In Massachusetts, we collaborated with two project developers and the state Department of Environmental Protection to install four solar farms on closed landfills. PSE&G is also finalizing the commissioning of a solar farm at Waste Management’s closed site at Cinnaminson in New Jersey. This year, we’re also planning to deploy solar on some of our facilities in California. These projects add up and translate to more than 50 MW and growing of power utilizing solar!

All of these innovative technologies are transforming waste stream materials into high-value resources. That’s what we do at Waste Management – and how we think differently about renewable energy.

The New Plastics Economy’s “Global Commitment” defies commonsense

The “root cause” solution to plastic pollution is in making sure plastics work in today’s managed-waste systems. It seems too simplistic an answer considering the enormity of this problem. But when it’s all said and done, plastics (petroleum or plant based) must work in our managed systems, especially the one that primarily collects plastic waste – period. This is the only path to a full life-cycle and systems approach for profoundly better economic and environmental outcomes.

Plastics are created from energy and, through our managed systems, plastics should ultimately be recovered as clean energy, closing the loop and ensuring plastics never become “waste”. Energy growth is directly linked to well-being and prosperity across the globe. For developing nations, this need is fundamental to improving and even saving lives. Energy is the building block for creating plastics and ensuring Energy’s recovery at the end-of-life is essential in eliminating pollution and achieving Circularity.

Which brings me to the New Plastics Economy’s “Global Commitment” pledge which states, “The Foundation believes the use of anaerobic digestion is currently limited for plastic packaging as at the date of publication,” to justify the focus on Compostability as the only acceptable end-of-life solution, but only for “specific” and “targeted” applications. Otherwise, it’s Recycle or die! The myopic pledge even doubled-down declaring that plastics-to-energy is not part of the circular economy target state! A stance that is radically shortsighted and naïve considering the scope of this crisis and the current state of Recycling.

But what strikes me as incredibly odd is that out of the dozens of experts, the broad stakeholder review process involving 100 organizations and experts across businesses, governments, NGO’s, academics and standard-setting organizations, you’re telling me that nobody noticed that this statement is completely ass-backwards?!?

The vast majority of plastic packaging is commonly and customarily discarded in facilities that are large-scale Anaerobic digestors (a.k.a. modern landfills) Limited? Not true, nearly 90% of U.S. Municipal Solid Waste (especially plastic packaging, because that’s what it is – not organic waste) is sent to anaerobic waste systems (practice and scale) – BTW, 0% to Industrial Composting facilities! These anaerobically managed MSW facilities are actively collecting and turning waste into fuel for vehicles, heat for homes and providing power to industries. They are highly regulated and strictly managed, and no other waste-management system collects more discarded plastics – none!

We have a pollution crisis and to get any tangible grip on this problem plastics must work in the systems that are available to us today. Strategies and pledges based on contingencies and “further innovation” only stagnate our abilities to act now. Recycling will never be a solution to pollution. We have systems in place and technologies available to make meaningful strides today, based on data, science and certainty that eliminate pollution with return value, not just continuing to “fight against” it with sentiment and no substance.

Energy recovery must be included in strategy and design, it is the alpha and omega. From where it comes, it must return. Negating this principle in the management of plastics is blasphemous to the fundamental principles of “Circularity” and only serves to continue down a linear path that solves nothing.

Global Landfill Gas Market is set to grow appreciably owing to stringent norms associated with greenhouse emission.

The report “Landfill Gas Market Size, Industry Analysis Report, Regional Outlook (U.S., Canada, Brazil, Germany, Italy, France, UK, Netherland, Russia, China, India, Malaysia, Singapore, South Africa), Application Development, Competitive Market Share & Forecast, 2017 – 2024” Rising demand for the clean energy technologies will further enhance the industry outlook across the forecast period. In 2016, Singapore government had setup a new target towards the reduction in carbon emission by 36% by 2030 below 2005 levels.

Depleting conventional resources leading to growing energy security concern will positively steer the global landfill gas market. Effective energy utilization and integration of competent equipment will further drive the technology by 2024. In 2017, UK based Brunel University in collaboration with a waste management firm Mission Resources have announced development of a Home Energy Recovery Unit (HERU) to heat water in the country.

Rising waste disposal leading to increasing waste to energy techniques will foster the global landfill gas market share by 2024. Government favorable waste management initiatives will thrust the global industry. In 2017, the Australian government have initiated a USD 2 million program in support of waste to energy technologies across Victoria City.

Complex design of treatment facility and inconsistency of waste composition will hamper the global landfill gas market. Extensive urban population growth favoring to the domestic solid waste technology leading to low generation rates and enhanced treatment technologies.

On the basis of application, the global landfill gas market can be segmented into utility flares, pipeline-quality, process heater, leachate evaporation and electricity generation. These applications are anticipated to grow substantially complying to growing environmental concern and industrialization across the globe. In 2017, the Federal Energy Regulatory Commission(FERC) has approved the settlement that provides a single natural gas quality specification for heavier hydrocarbons and ethane in the U.S.

Landfill gas market from electricity generation is set to grow appreciably pertaining to developing distributed generation technology and intensive growing demand for electricity. In 2016, the U.S. based ENER-G systems piloted an independent USD 7.58 million, 11MW landfill gas to power project in South Africa. Landfill gas market from utility flare is anticipated to grow considerably with increasing demand for reduced carbon emission technologies across the globe. The U.S. based Atlantic County Landfill Energy has established a USD 440,000 worth enclosed flare to reduce excess methane to electric plant besides the landfill in New Jersey.

Landfill gas market from pipeline-quality gas is set to grow appreciably owing to stringent government initiatives and advanced infrastructure implementations across the globe. In 2017, Wiscosin council has requested for installation, delivery and fabrication of a biogas treatment system in compliance to convert landfill gas into high-BTU biomethane in the U.S.

Key players in the global landfill gas market are namely, Waste Management Inc., Infinis, Veolia, A2A Energia, Aterro Recycling Pvt. Ltd., AEB Amsterdam, Shenzhen Energy, Babcock & Wilcox technology implementations. Mergers & Acquisitions and effective turnkey project implementations and are the key market player strategies. In 2017, UK based Veolia acquired Kurion, the U.S. for USD 350 million to expand its presence across nuclear waste business.

Something might be missing in that sustainable packaging playbook.

As we embark on 2017 a number of companies have rolled-out their packaging sustainability initiatives. I have to wonder, what the heck are some of them doing?  Last I checked the major problem is still the environmental impact that plastic waste is having on our planet – right?  I assume so, considering the latest projections estimate more plastic waste in the oceans (by weight) than fish by 2050. Which is plausible since production is through the roof and expected to double in the next 20 years, while we continue to struggle with dismal recovery rates and an antiquated view of recycling.

You might have also noticed an increase in the demand for clean, renewable energy.  With the world needing to greatly increase energy supply in the future, especially cleanly-generated electricity, this has become a top prioritySo, with that being said, how is it that the major producers of single-use plastic packaging seem to be unable to truly define the most common means of disposal and the value that can be achieved by simply complying with this fact?  Instead, they continue to irrationally demonize an asset that sits right under their proverbial noses.

Let’s try this exercise together. Let’s say you’re one of the giant producers of plastic packaging (Unilever, Coca-Cola, General Mills, Nestle, Pepsico, Kraft) and I were to ask you, what’s the most common disposal method of the plastic packaging you produce?  The collective and honest answer, albeit extremely basic, is a landfill. However, before panic sets in over this fact, let’s take a moment to define this a little more accurately.  Because today, 85% of all municipal solid waste in the U.S. actually ends-up in well-managed and heavily regulated anaerobic environment that controls and converts biogas into clean renewable energy. This is a fact and these facilities are generating power for communities and businesses, providing heat for homes and fuel for vehicles.

Can we stop pretending that this is a mystery? Recognize the innovations around how we manage waste and see what’s happening today. GM harnesses landfill-gas-to-energy for its 2.08-million square-foot facility reducing greenhouse gas emissions by a whopping 5,000 tons a year!  Tammy Giroux, manager of government relations for GM said, “(It’s) good for the environment, good for business and good for the community.” Waste Management’s landfill-gas-to-energy facilities power the equivalent of 470,000 households, offsetting 2.5 million tons of coal and 2.5 million tons of carbon dioxide emissions per year. At the 2016 Resource Recycling Conference in New Orleans, David Steiner (former CEO of Waste Management) specified, “When you combine state-of-the-art landfill gas-to-energy systems with best-in-class recycling…That’s where you get the biggest bang for the buck environmentally.”  So why aren’t these major producers of single-cycle packaging including energy recovery as part of the overall “recycling” efforts and ensuring performance compliance with this asset?

Please don’t tell me that the molecules that make-up my bag of chips are far too valuable to waste and that it would make more sense to collect, sort and process this material into a worthless commodity rather than ensuring its removed from the environment and converted into energy.  Or worse, jeopardize both product stability and performance (including the ability to recycle) to achieve performance compliance with the least common disposal method that offers no end-of-life value.

According to the Environmental Research and Education Foundation (EREF), consumers are generating 6 lbs. of waste per day. It would take heavy-handed regulations and stiff government subsidies to program consumers into becoming hyper-vigilant garbage sorters.  For the foreseeable future, the political atmosphere does not appear to be conducive for such tactics.  We need to be smarter about the options before us and increase the value that can be derived from our existing infrastructures.  When high recycling rates are touted around the world, they usually include waste-to-energy.  Yet, too many companies still manage to overlook this valuable resource, disregarding the intrinsic environmental and economic benefits that it offers.   Hopefully, as we set forth into a new era, more emphasis will be placed on using LCA’s and factual scientific data to address the sustainability challenges we face.

Landfill Gas-to-Energy Turning waste into energy.

ENGINEERING MARVELS
Advanced Disposal’s landfills are impressive engineering structures that offer proven protection to the natural environment while providing a vital service to governments, businesses and residents. They are managed and operated meticulously, providing a safe and cost-effective disposal option for community waste.

Advanced Disposal engineers and designs its facilities with the latest technology in the waste industry. We incorporate state-of-the-art systems that include: Bottom Liner Systems, Leachate Collection Systems and Gas Collection Systems for our municipal solid waste (MSW) landfills.

ENERGY CONSERVERS

Landfill gas collection systems are how modern landfills deal with gases created within the waste. The landfill gas that is collected contains approximately 50% methane and is either destroyed by combusting it in a flare or is diverted to an on-site treatment facility for the conversion of this gas to energy. The conversion of landfill gas to energy is an effective means of recycling and reusing this valuable resource.

Here’s how the process to convert this valuable resource to energy works: as landfill cells are filled with waste, methane gas, a byproduct of any decomposing material, is collected from within the waste through a system of vertical wells and pipelines and directed to a separate on-site treatment facility. The treated landfill gas is either pumped off site to a manufacturer near the landfill to supplement or replace their natural gas usage or is used to generate electricity right at the landfill that is delivered to the electrical grid.

Another benefit of the destruction or utilization of this landfill gas is that it prevents the raw methane in the gas from escaping into the atmosphere as a greenhouse gas. At some Advanced Disposal landfills, the installation of these collection systems to destroy the methane in the landfill gas is done on a voluntary basis, and thus, we receive credit for reducing the impact of this greenhouse gas on the environment. Advanced Disposal is a registered participant with the Climate Action Reserve and upon completion of a thorough verification process established by the Reserve, Advanced Disposal is awarded carbon offset credits that can be sold to other consumers or utilities that desire to offset their greenhouse gas generation.

The U.S. Environmental Protection Agency (EPA) has endorsed landfill gas as an environmentally friendly energy resource that reduces our reliance on fossil fuels, such as coal and oil. Advanced Disposal is an active participant in landfill gas-to-energy projects at our MSW landfills and continues to look for smart solutions for solving our community’s needs.

Is recycling the key to sustainability?

graphThe 2015 U.S. plastic bottle recycling rate posted a slight decrease of 0.6 percent compared with 2014, according to the figures released by the Association of Plastic Recyclers (APR) and the American Chemistry Council (ACC) in the 26th annual “National Post-Consumer Plastics Bottle Recycling Report.” At the current and projected rate of production, a plateau like this should ring alarm bells!  The data clearly shows we are not going to recycle our way to a sustainable future.

As someone who’s actively engaged in the sustainable management of plastics, I pay close attention to companies that are managing our waste. These companies are on the frontlines of managing the recovery and disposal of solid and hazardous waste materials, which include landfills and recycling centers. I strongly believe that integrating the advice from these groups and working with them hand-in-hand should be an integral aspect to any sustainability program.

For example, at the recent 2016 Resource Recycling Conference in New Orleans, CEO of Waste Management, David Steiner, specifically pointed out that in order to achieve the “biggest bang for the buck” environmentally, coupling recycling with landfill gas-to-energy offers the greatest return value. This is the “environmental” recommendation from David Steiner, not a shareholder perspective. And Waste Management should know, they are after all the ones actually doing all the work in collecting, processing and managing the vast majority of the our waste.

His shareholder perspective is profitability, as it should be.   In a recent interview with Bloomberg, David Steiner explains that when you look at the various commodities that are recycled, there are some that are profitable. Those are primarily fiber (paper) and metals. Once you start moving into organics (plastics) and glass, they become less profitable (and in most cases over the past few years, they have lost money). In places like California they’ll do things to subsidize those types of materials to ensure Waste Management makes a profit, and then people can recycle those materials… Elsewhere, this does not work economically and understandably so. However, Waste Management will do what the municipality wants, just not at the expense of its bottom-line.   They’ll be happy to recycle everything; it’s only a matter of how much you want to pay for it. But buyers beware if the commodity prices do not cover the processing costs, recycling becomes an exercise in futility.

Nonetheless, if the municipalities are willing to pay (increase taxes) for this exercise, Waste Management will be happy to oblige. They will “recycle” it, collect it, sort it and they will process it. For Waste Management, processing costs and a little profit are baked into the contract. If there’s no market, no problem for Waste Management, this material will end up disposed into a form that is not recycling.

Recently at K 2016, Patrick Thomas, chairman of the European trade group Plastics Europe, said that “every tonne of plastic that goes to landfill is a waste. It is too valuable a resource to go that way.” Really, if it needs to be subsidized by the government (tax payer money), what value is he referring to and is it sustainable?

Where exactly is the value? Last year the average bale price of recycled bottles fell by 31%, meaning that the bottles were less valuable last year than the year before. Couple this with oil prices dropping by 47% and the result is a compounded decrease in the “value” of recycled plastics.

Today, 80 million tons of non-reusable/non-recyclable plastic packaging is produced annually. This volume is expected to double in 20 years. If this 80 million tons were simply designed to comply with the primary disposal method (a.k.a. modern landfills), this material could provide enough energy to power 30 million homes for a year!

Nearly 50 years has passed since the launch of the first universal recycling symbol, today only 14% of plastic packaging is collected for recycling. When additional value losses in sorting and reprocessing are factored in, only 5% of material value is retained for a subsequent use. Meanwhile, in a business-as-usual scenario, the ocean is expected to contain one ton of plastic for every three tons of fish by 2025, and by 2050, more plastics than fish [by weight].  What are we doing?

There’s a pervasive attitude that we must recycle everything at all costs, this is not sustainable by any definition. Plastics, unlike aluminum, can only be recycled 3-4 times; eventually it will find its way into our waste streams and into our environment.   Although recycling does provide us the option to extend the life of some plastics, it is not an ‘end-of-life’ solution. We cannot recycle our way out of the environmental waste problem plastics are causing. If companies continue to ignore performance compliance with todays’ primary means of disposal, facilities that actively control and convert biogas into clean alternative energy (intrinsic return value), progress will remain stagnate. The science and data validate David Steiner’s recommendation; including landfill gas-to-energy provides an environmental and economic value higher than any other option.  We can take the advice or not, Waste Management will come out ahead either way, but will we?

Renewable Energy: GM Plant Using Landfill Gas to Produce 54% of Its Electricity

A General Motors (GM) assembly plant based in Lake Orion, Mich., is ranked as the eighth largest user of green power generated onsite in the United States among the Environmental Protection Agency’s Green Power Partnership (GPP) partners. Over half of the automaker’s plant is powered by methane captured from a nearby landfill.

Orion Assembly, where GM’s Chevrolet Bolt EV is built, saves $1 million a year by using renewable energy. The plant also is home to a 350-kilowatt solar array that sends energy back to the grid.

The EPA launched the GPP in 2001 to increase the use of renewable electricity in the U.S. It is a voluntary program that encourages organizations to use green power as a way to reduce the environmental impacts associated with conventional electricity use, according to the EPA website.

Waste360 recently sat down with Rob Threlkeld, global manager of renewable energy for General Motors based in Detroit, Mich., to discuss the company’s use of renewable energy.

Waste360: What is the process or technology used to capture the methane?

Rob Threlkeld: Landfill gas wells are installed in the landfill to capture the methane. A vacuum pulls the gas from the well through a pipe system. The gas is compressed and dried and sent to GM Orion Assembly to generate electricity. The compressed landfill gas is burned in on site generators to make electricity.

Waste360: How much energy is created and how is it used?

Rob Threlkeld: Orion Assembly generates up to 8 megawatts of electricity from landfill gas and that electricity powers the plant. Orion is producing 54 percent of its own electricity instead of buying it from a utility.

Waste360: Which landfills does the methane come from and what are their histories?

Rob Threlkeld: The landfill gas used at Orion Assembly comes from two nearby landfills, Eagle Valley, which is owned by Waste Management, and Oakland Heights Landfill, which is owned by Republic Services.

We’ve been pulling landfill gas from both landfills since 2002 to generate steam for heating and cooling. We’ve since reduced steam loads to the plant by improving the facility’s energy efficiency. In 2014, we started producing electricity from landfill gas on site. Fifty-four percent of the site’s electricity consumption comes from landfill gas. Both landfills are still open.

Waste360: Why did GM decide to become an Environmental Protection Agency’s Green Power Partnership Partner?

Rob Threlkeld: We decided to become an EPA Green Power Partner to help show our leadership position in the renewable energy space and demonstrate the benefits of using renewable energy, including reduced energy costs and reduced CO2 emissions.

Waste360: How does the program benefit GM?

Rob Threlkeld: The GPP provides a third party stamp of our leadership in the renewable energy space to address climate change and reduce energy costs. We’re also eager to promote the use of renewable energy and make the case that other corporations, big and small, can use it, too. Being a Green Power Partner also provides tools and resources like communications assets, trainings and opportunities to connect with other partners.

Waste360: How many other GM plants use renewable energy?

Rob Threlkeld: Twenty-eight facilities use some form of renewable energy. Several sites, like Orion Assembly and Fort Wayne Assembly, source multiple types of renewable energy. Both of these facilities use landfill gas for electricity and host solar arrays. Combined, our facilities promote the use of 106 megawatts of renewable energy globally.

GM is a member of the Buyers Renewables Center and the Renewable Energy Buyers Alliance. These organizations aim to accelerate corporate renewable energy procurement to help address climate change. As a member of these groups, we can share best practices in renewable energy procurement with others who are looking to scale up.

Turning trash into energy makes good business sense

Many people probably don’t think their local landfills are more than a final resting place for waste. But companies like Apple and General Motors are using them as a source of renewable energy that reduces their costs and impact on the environment.

On average, Americans throw away five pounds of trash per person per day. Despite widespread efforts to encourage recycling and reuse, a Yale University research team found Americans only recycle about 21.4% of their waste. The resultant constant supply of decomposing trash makes landfills the third-largest human-created source of methane emissions in the US.

Methane as a greenhouse gas is 20 times more potent than carbon dioxide (CO2). Unregulated and untreated, it can lead to smog, contribute to global warming and even cause health problems. But there’s a silver lining: generating energy from methane offers benefits like improved air quality and reduced expenses and waste.

To that end, a landfill gas energy project captures 60% to 90% percent of methane generated in the dump. It also avoids the greenhouse gas emissions from fossil fuels that would have been used otherwise.

Trashy transformation

Here’s how that food wrapper or hole-filled sock you threw away turns into electricity.

1 After nearly a year of sitting in a landfill, bacteria begin to break down the waste and generate methane as a natural byproduct.

2 As sections of the landfill are filled, they are capped and closed off to additional garbage. Methane collection wells are added.

3 Methane is collected in wells or trenches that are connected to piping. A vacuum or blower system pulls the gas through the pipes to a collection head, which sends the gas to a treatment system.

4 The warm landfill gas cools as it travels through the collection system. The gas is treated to remove water condensation as well as particulates and other impurities, keeping the system clear so that energy recovery is not disrupted.

5 The methane passes through another filter where it is compressed.

6 The gas is then piped to a plant where electricity is generated, powering the facility’s engines or turbines which generate the power.

The US Environmental Protection Agency (EPA) estimates that about 0.67 megawatts of electricity is produced for every 1m tons of solid municipal waste. Landfill gas helps to manufacture items we use every day – such as aluminum, electronics and vehicles. Landfill gas can also be sent to a boiler to generate steam for a building’s heating and cooling system.

Companies benefit while helping the planet

GM invested in electrical generation equipment in 2013 to convert landfill gas to energy, making it the first automaker in North America to invest capital to create its own electricity. The equipment at GM’s Fort Wayne, Indiana, and Orion, Michigan, assembly plants together generate more than 14 megawatts of electricity from landfill gas. This helps the company avoid producing more than 89,000 metric tons of CO2 per year – equivalent to the annual greenhouse gas emissions of 18,542 passenger vehicles.

It’s a strong business case: GM saves several million dollars annually at these facilities. It also acts as a long-term hedge against volatile energy prices. Both plants rank on the EPA’s Green Power Partner list of top onsite generators of green power.

Apple recently secured an agreement with North Carolina to build a facility that generates electricity from landfill gas. Although all of Apple’s US operations are completely powered by renewable energy, the project supports the company’s new subsidiary, which sells surplus power generated by its solar farms to other companies.

Landfill gas projects are on the rise. Their number increased by 300% since 1995 in the US, according to the EPA. Today, 648 operational projects create 2,099 megawatts of energy. An additional 400 candidate landfills have the potential to support such projects.

The EPA’s Landfill Methane Outreach Program (LMOP) provides assistance for companies that are thinking about adding landfill gas to their renewable energy portfolios. EPA LMOP connects businesses, agencies, organizations and governments to experts.

“EPA applauds organizations’ demonstrated use of green power as a means to reduce their own carbon footprint,” said James Critchfield, manager of EPA’s Green Power Partnership. “Organizations are increasingly realizing meaningful environmental and economic benefits, particularly when they engage with new renewable energy projects.”

With so many active projects found in the US and around the world, the use of landfill gas as a resource is expected to grow. Germany, the world’s top producer, generated enough electricity this way to power 3.5m homes in 2009. Methane may also be purified to create the liquefied or compressed natural gas that powers many garbage trucks and city buses.

“Capturing landfill gas for energy makes sense from a business perspective, but the biggest benefit is to the environment,” says Rob Threlkeld, GM’s global manager of renewable energy. “If we can capture a greenhouse gas and prevent it from entering the atmosphere while generating a cost savings, that’s a win all around.”

The Top 10 and Not a 1?

companies

 

 

This diagram represents the top ten producers of plastic packaging. The vast majority of the plastic applications that are produced by these brands become waste. All the film packaging, pouches, diapers, detergents, hygiene products, wrappers, coffee bags, food containers and much more, that’s produced by these 10 companies accounts for an astonishing amount of the plastic waste that is certainly not being reused or recycled in any meaningful way.

We hear a lot that environmental pollution is a consumer problem. We get told how to prepare our waste for recycling. “Put this here and put that there. No! Not that, this. Well, sometimes that, but probably not. Maybe, use water and wash it out. No wait – water..? Take it here or actually take it someplace over there.  Otherwise, it may need to be shipped somewhere..?”  And when you stop to take a look at the results of all this effort, you’re left wondering, are you kidding me, is all this even environmental? Enough already!

News Flash: In the last 50 years, we’ve invested heavily in how we manage waste and the infrastructures we utilize. They’re very impressive works of innovation and they’re regulated for environmental efficiency at the highest level. In fact, today 85% of all U.S. municipal solid waste ends-up in an environment that converts biogas into clean energy, generating a valuable alternative resource for our growing energy needs. Some of these companies are actually using the same means to power their own manufacturing facilities! Yet, accountability for this aspect in packaging design is scarce. How is this being overlooked?

We’re now dealing with decades of plastic waste that’s been left in our environment; we see the devastating repercussions and the projected damage it will cause. Plastic production has surged to 311 million tons and is expected to double in 20 years. Currently, plastic packaging accounts for nearly a third of the total volume of plastics used, and unlikely to be recycled. By ignoring the single most common disposal method of this material, valuable energy is being wasted and continues to compound the environmental problem.

If these 10 companies took one simple step to ensure packaging design for disposal compliance, the impact would provide tremendous and measurable value, for company and community. Getting plastics out of our environment and into the grid falls on the shoulders of producers not consumers.

Ensuring energy recovery should be paramount in packaging design, it’s the only opportunity to recoup value and it should be the top consideration in packaging sustainability initiatives.

The three new plants, combined with Republic’s Hickory Ridge landfill operation, establish Republic and Mas Energy’s landfill gas-to-energy portfolio as the largest in Georgia.

Republic Services Inc. recently unveiled a new renewable energy project with partner Mas Energy LLC that will serve the Metro Atlanta area, generating 24.1 megawatts of electricity, or enough renewable energy to power 15,665 households.

“The energy will be supplied to Georgia Power for distribution throughout the local electric grid. In all likelihood, Georgia Power’s retail electric customers in Metro Atlanta will utilize the energy,” says Michael Hall, principal and chief development officer for Mas Energy based in Ponte Vedra Beach, Fla.

Their agreement, which also includes partners Georgia Power, I Squared Capital, Crowder Construction Company and Nixon Energy, is for 20 years and will convert methane captured from three local landfills at gas-to-energy facilities in the cities of Buford, Griffin and Winder. Those landfills combined have an approximate daily volume of 7,000 tons.

The three plants, combined with Republic’s Hickory Ridge landfill operation, establish Republic and Mas Energy’s landfill gas-to-energy portfolio as the largest in Georgia,” says Michael Meuse, general manager for Republic Services in Atlanta, Ga.

Landfill gas-to-energy projects like these involve capturing methane, a byproduct of the normal decomposition of waste, from the subsurface and routing the methane to a series of engines. These engines convert the methane into electricity, which can be distributed to the local power grid.

“Methane is a greenhouse gas that is naturally produced as organic waste breaks down anaerobically in landfills,” says Meuse. “Methane gas is recovered by the gas collection systems. Gas wells are driven into the waste mass and powerful blowers are used to create a vacuum to draw out and pipe the gas to the energy plant.”

The system then converts the methane gas into a clean-burning fuel.

“The power generation facility utilizes internal combustion engines fueled by the collected and treated landfill gas to produce electricity, which is then delivered to Georgia Power’s transmission and distribution system,” says Hall.

The partnership was fueled by Georgia embracing renewable and clean energy projects within state lines.

“In 2006, Georgia’s Public Service Commission established the ‘QF Proxy Unit Methodology’, whereby qualifying facilities in the state of Georgia were eligible to enter into power purchase agreements (PPA) with Georgia Power that recognized the full value of renewable and clean energy to Georgia consumers,” says Hall. “Mas Energy secured its PPA in early 2014 and brought Republic Services a proposal to build plants at Republic’s Atlanta sites.”

Republic and Mas Energy had previously collaborated on a project at Republic’s now-closed Hickory Ridge landfill site.

“Based on that positive experience, the agreements were made between Mas Energy and Republic Services to develop the (recently announced) projects,” says Hall.

Meuse says that according to the U.S. Environmental Protection Agency (EPA) calculations, energy produced from landfill gas-to-energy facilities will offset the equivalent of: carbon dioxide (CO2) emissions from 127,795,779 gallons of gasoline; carbon sequestered by 930,919 acres of U.S. forests; and carbon dioxide (CO2) emissions from 6,090 railcars’ worth of coal burned.

“Projects such as these reduce reliance on non-renewable resources (coal and natural gas), reduce methane emissions from the site, and eliminate emissions from flares previously used for gas destruction,” he says.
