101 For RINs
November 3, 2017 – Digester operators and developers are increasingly interested in upgrading biogas into renewable fuels, and tapping economic opportunities in the form of RINs. The biogas industry is keenly focused on economic opportunities resulting from the generation of upgraded biogas to renewable fuel and its attached environmental credits, called RINs, or Renewable Identification Numbers. Congress created the renewable fuel standard (RFS) program, which the U.S. Environmental Protection Agency implements under consultation with the U.S. Department of Energy, to reduce greenhouse gas (GHG) emissions and expand the nation’s renewable fuels sector while reducing reliance on imported oil.

California funds 18 dairy digester projects
November 9, 2017 – The California Department of Food and Agriculture has awarded $35.2 million to 18 dairy digester projects. The projects are part of the Dairy Digester Research and Development program and aim to reduce greenhouse gas (GHG) emissions from manure at California dairy farms. “California continues to the lead the nation in supporting smart climate programs that address on-farm challenges and promote agricultural sustainability,” said CDFA Secretary Karen Ross. “I applaud our dairy farmers for proactively addressing climate pollutants and reducing overall greenhouse emissions to help meet the state’s climate goals.”
Strengths and barriers in the development of biogas post 2020 in the European Union
November 10, 2017 – The research study entitled “Technical assessment study for biogas optimal use post 2020”, commissioned by the European Union, identifies the main strengths and weaknesses of the biogas and biomethane markets in the Union’s 28 member states. Factors favouring the market’s development are a stable political environment and sustainability targets set at the European level. The lack of the same factors, on the other hand, together with an absence of incentives, are among the main barriers.

BPA, ABC ask for parity in tax reform package
November 10, 2017 – The Biomass Power Association and American Biogas Council recently partnered with the Energy Recovery Council and National Hydropower Association to ask Congress for tax parity for all renewable technologies in tax reform. On Nov. 7, the four trade groups sent a letter to Rep. Kevin Brady, chairman of the House Committee on Ways and Means and Sen. Orrin Hatch, chairman of the Senate Committee on Finance, asking them to provide parity and a level playing field for all renewable energy technologies as they craft tax reform legislation.
$100,000 biogas scrubbing feasibility study approved in Canadian City
November 10, 2017 – The council of Chilliwack, a city in British Columbia, Canada, has approved a major study to look for alternatives to flaring biogas from it wastewater treatment plant, according to The Chilliwack Progress. At present, three anaerobic digesters at the wastewater plant emit a substantial amount of biogas – including major greenhouse gases carbon dioxide and methane. The Chilliwack Progress reports that the plant’s biogas output is set to increase in the future, with a planned high-strength wastewater pretreatment facility set to be built at the site as part of a new Molson Coors brewery.

Simulating sludge: a novel approach to visualising anaerobic digestion
November 13, 2017 – The process – the most widely used sludge treatment method – uses microorganisms, in the absence of oxygen, to break down organic material into carbon dioxide and methane gas. ‘Because you need to mix the sludge in order to carry the treatment process further, it consumes a lot of energy – and is therefore expensive. So, what we are trying to do is to find ways to mix it better in order to use less energy, and get a better balance between energy input and output.’ The problem is that sludge is an unpleasant material with which to work. Not only does it ‘stink’, but it is biologically and chemically hazardous and it is also opaque. This non-transparency makes it particularly difficult for scientists to understand how the sludge flows in an AD tank.

Poland could produce 2 billion m3 of biogas (1421 MW) from waste streams
November 13, 2017 – With a population of 38 million, Gross Domestic Product (GDP) growing at 3.9%, almost half of all land used for agriculture, and being a net energy importer, Poland has the feedstock, workforce, growing economy, and commitment to environmentally sustainable growth needed to foster a thriving biogas sector. Agricultural biogas plants in particular, supported by a new energy auction, are expected to drive biogas growth in Poland.
Key elements in the codigestion of different crop materials
November 14, 2017 – Various factors need to be considered in the codigestion of different crop materials, including effects on the viscosity of the digester, on palatability, and on the digestibility of the crop itself. The structural characteristics of the digester and the presence of pre-treatments should also be borne in mind.

Clean Energy To Supply Dallas Fort Worth International Airport With Renewable Natural Gas; DFW Becomes First Airport Outside California To Use Redeem™ RNG
November 15, 2017 – Clean Energy Fuels Corp. announced today at the Airports Going Green 2017 conference, that host airport Dallas Fort Worth International (DFW) Airport awarded Clean Energy a renewable natural gas (RNG) fueling contract for the airport’s vehicle fleet. The contract calls for Clean Energy to provide the airport with its Redeem™ brand of RNG, the first renewable and commercially available vehicle fuel made entirely from 100% organic waste. The use of RNG has the potential to reduce DFW fleet emissions by approximately 70%.

ADBA National Conference to take place in London on 7thDecember 2017
November 16, 2017 – The event will bring together the UK AD and biogas community to explore how the industry can be optimised to reduce emissions through the 2020s to help the government meet its Carbon Budgets. AD has significant potential to reduce emissions from heat and transport, whilst simultaneously supporting UK farmers and providing a management solution for food waste. The conference will address the most pressing issues in the AD sector, including support for renewable heat, post-Brexit on-farm AD, ADBA’s AD plant certification scheme, gas-grid injection, food waste collections, and biomethane for transport.
