Study Finds Recyclability Issues In Weight, Labels for PET Bottles

By Martín Caballero, BEVNET

For consumers, the recycling process begins and ends the moment they place a used plastic bottle in the bin.

For brands and bottle manufacturers, that process is considerably more complex. And as a movement towards sustainability and waste reduction continues to shape the industry, both are taking a closer look at how physical characteristics, design, and supplemental materials like ink and glue can affect the recyclability of bottles made with polyethylene terephthalate (PET).

Plastic Technologies Inc. (PTI), a firm that provides package design, development and engineering services to bottle manufacturers, explored this issue in a recent study analyzing how PET bottle weight affects performance, cost, and environmental impact, as well as how other design decisions influence recyclability.

The results concluded that ultra-lightweight bottles can negatively impact the effectiveness of recycling systems, while showing that the a majority of the bottles tested showed significant issues in recyclability, based on Association of Plastic Recyclers (APR) guidelines.

The study analyzed 500mL PET bottles, sold individually at room temperature, from the highest bottled water consumption regions where market-leading global brands are sold, including the U.S., Mexico, Europe (France, Italy, Switzerland), and India. Each were tested for weight, pressure, product volume, fill point, top load, thickness, section weights, color and closure types.

In an interview with BevNET, Marcio Amazonas, Director of Latin American Operations for PTI, said that study was partially intended to send a message to the category market leaders that good design, in terms of recyclability, can be a positive influence on the industry.

“We wanted to make this study as a competitive analysis to show who are the best brand owners in terms of a good design for recyclability,” said Amazonas. “It’s also sending a message to our own customers that we can help you improve your design.”

Weight is a crucial factor in determining bottle recyclability, but it has also increasingly become a way in which brands communicate a premium offering to consumers, and attempting to balance these two competing interests can make things even more complicated.

The samples evaluated from the U.S. reflected this stratification. Out of the seven, two samples came from premium-priced packages sold in 6-packs, which were around 22-23 g. The rest came from bottles of mid-range priced water, weighing 13-17 g, and value-priced bottles, weighing 7.5 to 8.5 g.

However, the study notes that the performance was not a direct correlation to the weight of the package.

“Sometimes the best ones were too heavy, so they are good in a way but they are not the most environmentally sound, because they could be lighter, Amazonas said. “But that’s a brand owner choice to position that brand as premium. So they want to go with the heavy plastic; that’s their call, but it’s not ideal for efficiency.”

In recent years, some brands, such as Nestlé Waters, have adopted ultra-thin, super lightweight bottles based on the idea that they are more environmentally friendly because they require less energy to manufacture and transport. Yet according to Amazonas, recyclers are complaining about problems related to those bottles as well.

For example, lighter packaging can increase the number of bottles entering the recycling stream; Amazonas estimated that it could add 10,000 bottles per ton of recyclable materials.

Furthermore, when labels are sorted in a process called elutriation, they are soaked in a large tank of water to separate PET from polyolefins. Afterwards, an air current dries the materials and pushes the labels out of the chamber, but if the bottle is too light, it will be forced out as well.

“The yields suffer not only because of the potential presence of non-PET, but also mechanically speaking, the process is designed for a certain density that suffers with this lightweighting,” said Amazonas.

Besides weight, Amazonas noted that ink and label type as other potentially disruptive factors to the recycling process, as materials, colors, sizes and even the label application process all have an impact.

Of the seven U.S. samples tested, five had polymer labels, one had paper and one had a combination of the two. Five out of seven samples used a wrap-around label, while two used an adhered label.

All seven U.S. bottle samples tested had labels that caused color and clarity change in the wash, and label bleed was the most common issue observed. The study concludes that “the use of soluble inks and glues and the specification of the label substrate could have resulted in much better recyclability scores.”

“I think the ink is one of the big issues because it is so simple to resolve, and of course [the brands] are all competing on price and going for the cheapest thing,” said Amazonas, noting the presence of other non-PET contaminants in labels, such as PVC, that burn at different temperatures can cause recycling operations to reject certain bottles. “So sometimes it’s an economic decision on the design side to get to lower cost labels, inks and glues, and that’s what makes the design a little poor.”

In terms of solutions, Amazonas said the ideal PET bottle from a recyclability perspective would be clear with no colorants and none of the chemical additives that are sometimes used to create a barrier between the plastic and the liquid in bottles of milk or juice.

On a moral level, he noted the efforts of regulatory agencies like the Environmental Protection Agency (EPA) in promoting sustainable materials management, and said that brands will seek to capture the market of conscious consumers who expect recyclability to be a key component of a company’s mission.

“The heaviest volumes of bottle-to-bottle use is here, so we have all the good reasons to thank the market leaders like the guys we tested and we keep pushing,” he said. “They are not doing anything horrible, but if we don’t talk about it they will probably go with the most economic solution.”

Yet despite his deep knowledge of the industry, Amazonas said that the most important logistical piece of the recycling process is the simple act of the consumer throwing the bottle into the collection bin.

“If there’s no collection, there’s no recycling — so what’s the point?”

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.

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.

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. It’s the missing link to creating circularity; it’s recycling at its highest peak. With an immediate 85% capture rate at the fingertips of corporate sustainability leaders, what are you waiting for?

A Look at the Largest Landfill Gas-To-Energy Project in Georgia

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.

Alameda and Palo Alto, CA, Use Landfill Gas as Reliable Source of Renewable Energy

One of California’s largest renewable energy projects, a landfill-gas-to-energy station at Republic Services‘ Ox Mountain Landfill in Half Moon Bay, has been generating renewable energy for the cities of Alameda and Palo Alto. The annual electricity generated by the Ox Mountain project prevents the release of 71,000 tons of greenhouse gas emissions into the atmosphere. That is the equivalent of taking 11,800 cars off the road.

Alameda Municipal Power purchases 85 percent of its power from renewable energy resources. The Ox Mountain plant alone provides approximately 11 percent of the electricity consumed in the East Bay community. This new facility is one of four landfill-gas-to-energy resources presently powering Alameda. As a result more than 20 percent of Alameda’s power is being generated by landfill-gas-to-energy plants.

As a result of its utility’s power portfolio, Alameda ranks among the lowest in greenhouse gas emissions in California. Known as “The Greenest Little Utility in America,” environmental responsibility has been a major criterion in power resource selection and development by the utility since the 1980s. “The landfill-gas-to-energy project at Ox Mountain allows us to offer our customers another carbon-free source of power, and continue our quarter century commitment to renewable energy,” said Ann L.

The nearby city of Palo Alto similarly had adopted goals of meeting 33 percent of its electric needs by 2015 with new qualifying renewable resources like the Ox Mountain Landfill. Palo Alto’s share of the project was projected to supply about 4 percent of the city’s electric needs. “Making use of this renewable energy resource reduces the amount of market power we have to purchase, which reduces the need for fossil fuel-powered electric generation in California,” said Peter Drekmeier, former Mayor of the City of Palo Alto. “By burning methane, which is one of the most potent greenhouse gases, this project has the added benefit of reducing greenhouse gas emissions from the landfill.”

Landfill gas is created when organic waste in landfills decomposes, producing methane–the primary ingredient in natural gas and a greenhouse gas. The landfill gas to energy plant captures the methane and turns it into electricity for use by residential and business customers. Converting landfill gas to energy prevents the release of greenhouse gases and creates electricity from a renewable, affordable source—reducing the need for power created from fossil fuels.

“The commissioning of this significant renewable energy resource for the people of California is another example of Republic’s commitment to the environment,” said Jeff Andrews, Senior Vice President West Region, Republic Services, Inc. “This is a larger plant in terms of renewable electricity production from landfill gas, and also represents the current best available technology for emissions controls, making it an extremely clean renewable energy source.”
