Methane is a potent greenhouse gas with a global warming potential more than 25 times that of carbon dioxide. Climate change threatens the health and welfare of current and future generations. Children, older adults, people with heart or lung disease and people living in poverty may be most at risk from the health impacts of climate change. In addition to methane, landfills also emit other pollutants, including the air toxics benzene, toluene, ethylbenzene and vinyl chloride.

WASHINGTON – As part of the President’s Climate Action Plan – Strategy to Reduce Methane Emissions, the U.S. Environmental Protection Agency (EPA) issued two proposals to further reduce emissions of methane-rich gas from municipal solid waste (MSW) landfills. Under today’s proposals, new, modified and existing landfills would begin collecting and controlling landfill gas at emission levels nearly a third lower than current requirements.  […]

Municipal solid waste landfills receive non-hazardous wastes from homes, businesses and institutions. As landfill waste decomposes, it produces a number of air toxics, carbon dioxide, and methane. MSW landfills are the third-largest source of human-related methane emissions in the U.S., accounting for 18 percent of methane emissions in 2013 – the equivalent of approximately 100 million metric tons of carbon dioxide pollution.

Combined, the proposed rules are expected to reduce methane emissions by an estimated 487,000 tons a year beginning in 2025 – equivalent to reducing 12.2 million metric tons of carbon dioxide, or the carbon pollution emissions from more than 1.1 million homes. EPA estimates the climate benefits of the combined proposals at nearly $750 million in 2025 or nearly $14 for every dollar spent to comply. Combined costs of the proposed rules are estimated at $55 million in 2025.

Today’s proposals would strengthen a previously proposed rule for new landfills that was issued in 2014, and would update the agency’s 1996 emission guidelines for existing landfills. The proposals are based on additional data and analysis, and public comments received on a proposal and Advance Notice of Proposed Rulemaking EPA issued in 2014.

EPA will take comment on the proposed rules for 60 days after they are published in the Federal Register. The agency will hold a public hearing if one is requested within five days of publication.  “<

>”WASHINGTON (Reuters) – The U.S. Environmental Protection Agency will propose regulations on Tuesday aimed at cutting methane emissions from the oil and gas sector by 40 to 45 percent over the next decade from 2012 levels, a source familiar with the issue said on Monday.

The regulations on methane are one part of the Obama administration’s strategy to curb greenhouse gases and combat climate change.

The targets in Tuesday’s proposal are in line with a January announcement by the Obama administration that it wanted to reduce oil and gas industry methane emissions by up to 45 percent from 2012 levels by 2025, the source said.

Earlier this month, President Barack Obama unveiled the final version of his plan to tackle greenhouse gases from coal-fired power plants, requiring carbon emissions from the sector be cut 32 percent from 2005 levels by 2030.

>”[…]

The expansion is part of a contract between St. Landry Solid Waste and Progressive Waste Systems. In exchange for continuation of its existing waste hauling contract with the District, Progressive Waste has agreed to purchase new CNG-powered trucks, and will have access to the increased BioCNG generated from the expanded system. The expanded project will also provide BioCNG fuel to additional St. Landry Parish clients.

St. Landry Parish Solid Waste Disposal District executive director Katry Martin, said, “The fact that the hauler that delivers waste to the Parish landfill will fuel its trucks with the biogas generated from the landfill is a true example of the power of renewable energy sources and a preview of the future of biogas.”

The St. Landry Parish BioCNG Vehicle Fuel Project received the U.S. Environmental Protection Agency’s Landfill Methane Outreach Program (LMOP) 2012 Project of the Year award. The system was originally designed to serve public works trucks and the sheriffs’ vehicle fleet. Now, with a new fuel purchaser, the District will increase on-site BioCNG production and provide an off-site CNG fueling station. The District can transport the BioCNG to the off-site location in a compressed gas tube trailer. […]”<

Swedish Stirling Engine Generator Converts Low Quality Landfill Gas to Energy in Poland

Posted on by

Swedish Stirling Engine generator specialist, Cleanergy supplies its GasBox generators to two landfill sites in Poland for the production of energy from low quality methane gas emitted from two major, following a successful pilot project earlier in the year.

Source: www.waste-management-world.com

>” […] GasBox – the centrepiece of its Combined Heat & Power (CHP) system – has been specifically developed to generate electricity and heat from low-quality methane gas produced by the decomposition of organic matter at the 2000+ landfill sites across Europe, most of which are more than 10 years old.

According to Cleanergy, many such landfill sites choose to flare the methane they produce.

The European Union Landfill Directive of 1999 states that flaring is only an option if it is impossible to extract energy from the methane gas. But up until today, older landfill sites have often broken these directives because the gas combustion engines traditionally used at newer landfills where methane levels are above 40% simply cannot produce electricity from lower grade, ‘dirty’ methane.

However, at the two Polish landfill sites the methane was released straight into the atmosphere rather than being flared.  To address this, Cleanergy’s GasBox was deployed at the Regional Centre of Waste Management in Domaszkowice in Poland in August.

This 25 hectare landfill site closed in the  2000. Since the installation of the GasBox, the electricity generated has been used to power equipment and to heat and electrify buildings at the site.

Following this success, Cleanergy’s CHP system has also been deployed at the Waste Neutralisation Enterprise in Sulnówko, a 7.5 hectare landfill site.

Anders Koritz, CEO at Cleanergy commented: “We developed our GasBox to meet a specific need – a complete CHP system that can run on low-grade methane gas. Sure enough the industry response since our launch in June has been amazing.”

According to Cleanergy its GasBox addresses this specific problem and is able to produce both electricity and heat from a methane gas concentration down to 18%.

Installed inside a modular container, Cleanergy’s GasBox is an autonomous and flexible stirling engine unit. Also inside the container is a real-time power management system with remote access; a fuel pipe; plus a heat and electricity connection to a house/factory/warehouse with optional grid functionality.

With a claimed ROI of three to five years, the company said that its GasBox is now commercially deployed at several locations in Norway, Slovenia, Sweden (in collaboration with the Swedish Energy Agency) and the UK. […]”<

Republic Services recently announced the start of operations at its latest landfill gas-to-energy project. The new 6 MW project at County Line Landfill involves four engines operating at one energy generation facility.

Source: biomassmagazine.com

>” […] Landfill gas is a natural byproduct of decomposing waste. This project involves extracting gas from within the landfill, processing the extracted gas, and then distributing the processed gas to a generation facility where it is converted into energy that supplies the local electric grid.

According to the U.S. EPA, landfill gas-to-energy projects also reduce reliance on non-renewable energy resources, such as coal or petroleum. The EPA estimates that three megawatts of energy produced from landfill gas is equivalent to preventing carbon emissions generated by the consumption of 16.6 million gallons of gasoline. Based on EPA calculations, the new County Line Landfill gas-to-energy project prevents carbon emissions equivalent to the consumption of more than 32 million gallons of gasoline.

Republic Services partnered with Aria Energy on the design, development and management of the new project. Republic Services and Aria Energy have partnered on four projects to date with a combined generation capacity of more than 39.6 megawatts of electrical power. Republic and Aria are currently working on two additional projects, which combined are expected to create another 15 megawatts of electrical power.

Republic Services has implemented 73 landfill gas-to-energy projects nationwide. Together, these projects harness enough electricity to power or heat approximately 400,000 households. According to the EPA, the combined environmental benefits from these projects are equal to removing more than 4 million cars from our roads or planting more than 4.5 million acres of trees each year.

UK offers Big Tax Breaks for Shale Gas Fracking

See on Scoop.it – Green & Sustainable News

Chancellor George Osborne has said that the Treasury will go ahead with the most generous tax regime for shale gas in the world.

Duane Tilden‘s insight:

>In the North Sea oil and gas exploration has received tax breaks along the same lines. This has brought about a renewed interest in this field, which is both technically very difficult and rather expensive. The tax allowance will see a huge relief for fracking, with a portion of each production sites income taxation going to a level of 30% in place of the 62% currently levied.

The British Geological Society has said that shale gas in northern England alone could be as high as 1,300 trillion cubic feet and just 10% of that would meet Britain’s needs for more than 40 years.

Water UK, a representative of Britain’s biggest water suppliers has voiced fears that large quantities of water needed for fracking would stretch water supplies very thinly in the areas earmarked for fracking sites, and there is a concern of contamination of water supplies with chemical waste and methane gas. Water UK said that damage could be done to the existing water pipe infrastructure with resultant shortages for home and business use.

Fracking companies say that lengthy waiting periods for environmental permission to begin fracking are a major concern, and Ministers have said they will endeavour to minimise the waiting period from over three months to under two weeks. Public support for shale gas exploration is low.<

Agriculture Secretary Vilsack today renewed a historic agreement with U.S. dairy producers to accelerate the adoption of innovative waste-to-energy projects and energy efficiency improvements on U.S. dairy farms…

Duane Tilden‘s insight:

USDA support for agricultural and waste-to-energy research has played a key role in the agreement’s success to date. Since signing the MOU, USDA has made nearly 180 awards that helped finance the development, construction, and biogas production of anaerobic digester systems with Rural Development programs, such as the Rural Energy for America Program (REAP), Bioenergy Program for Advanced Biofuels, Business and Industry Guaranteed Loan Program, Value Added Producer Grants, amongst others. These systems capture methane and produce renewable energy for on-farm use and sale onto the electric grid. Additionally, during this period, USDA awarded approximately 140 REAP loans and grants to help dairy farmers develop other types of renewable energy and energy efficiency systems at their operations.

See on Scoop.it – Green & Sustainable News

WASHINGTON, April 18, 2013 /PRNewswire-USNewswire/ — The waste and recycling industry is continuing to reduce its release of greenhouse gases — even as waste volumes increase, according to the latest greenhouse gas inventory released by U.S. Environmental Protection Agency (EPA).

Duane Tilden‘s insight:

Despite the fact that we are landfilling 6 percent less than 20 years ago, we have greatly improved our ability to reduce methane emissions. As a result, these emissions declined by 30 percent during the same period. This has happened as a result of converting methane to energy, flaring of methane emissions and oxidation techniques.

There are 594 landfill gas-to-energy sites in the United States that generated 1,813 megawatts (MW) of energy and 312 million standard cubic feet a day (mmscfd) of gas. This is enough energy to directly power 1 million homes and heat 729,000, respectively.

Methane gas collected at landfills is used to power home, businesses and government facilities across the nation. Some of it is even used to fuel garbage trucks. Landfill-gas-to-energy projects and other forms of biomass-derived energy make up the almost half of the nation’s renewable energy supply, almost the same amount as is derived from solar, wind, geothermal and hydropower combined.

Lycoming County was one of seven places in the country to receive the U.S. Environmental Protection Agency’s award for excellence in landfill gas energy projects for 2012.

Duane Tilden‘s insight:

Yaw, who was present at Thursday’s presentation at the commissioners’ meeting, said he frequently became frustrated when driving by the landfill and seeing excess methane being flared off.

“We’re utilizing all of the landfill methane (now). We’re not flaring anything,” said Tucker.

The county’s waste gas-to-energy project produces enough electricity to power 4,000 homes a year and has the equivalent reduction of 80,000 barrels of oil a year, according to PPL Renewable Energy.

Donna Zickefoose, Allenwood Federal Correctional Complex warden, said the local institution is the first federal prison to be involved in such a project. She said it will save the prison $5 million during the next decade.
