IEA Task 37: how anaerobic digestion reduces emissions
November 16, 2017 – DThe IEA Task 37 working team has analysed the potential of anaerobic digestion for reducing emissions into the atmosphere. The study areas include agriculture, dairies, municipalities, algae and microalgae. These are all areas in which biogas has a role – we discuss this with Jerry Murphy of IEA Task 37.

The Danish gas grid could be filled with green gas in 2035
November 16, 2017 – According to a memorandum published by Green Gas Denmark on the 14th of November, Denmark’s gas grid could be running entirely on green gas in 2035. Thus, Denmark could be the first European country to become independent of natural gas and cover their consumption entirely through gas produced from food waste, industrial waste and agricultural by-products.

UPS Boosts Supplies of Renewable Biogas
November 20, 2017 – This morning, UPS announced that it has entered into an agreement to purchase up to 11.5 million gallon equivalents of renewable biogas a year well into the next decade. This gas, which is also known as renewable natural gas (RNG) or biomethane, is interchangeable with conventional natural gas, by which much of UPS’ fleet has long been fueled. Proponents of the consumption of this biogas note that its adoption can reduce greenhouse gas emissions by up to 90 percent when compared to what is emitted when using conventional diesel. The biogas that UPS will source will come from sources such as municipal landfills, livestock operations and waste treatment plants.
The Challenges Siloxanes Pose to Landfill Gas-to-Energy Operations
November 21, 2017 – As more operators convert landfill gas into electricity or transportation fuel, siloxanes—chemicals common in cosmetics, cleaning products and industrial applications—are becoming more of a headache. Siloxanes that are landfilled can volatize into biogas. And this can wreak havoc on power-generating equipment. “When the gas is combusted to make power, siloxanes are converted to silica, which can deposit on the combustion [equipment] surfaces,” says Kenneth Kruszynski, principal at Civil & Environmental Consultants in Lombard, Ill.
Why and how to use digestate on Italian farms
November 21, 2017 – Better growing conditions and the dynamic storage of carbon in the soil are among the main benefits for farmers when they use digestate, as well as greater soil resilience. There are also several positive agronomic and financial implications that farms can benefit from provided that they are aware of the digestate’s characteristics, in accordance with the new Italian decree (agro-zootechnical or agro-industrial). We find out more about the new decree with Guido Bezzi of the CIB.

19 countries agree to scale up bioenergy targets
November 21, 2017 – Countries representing half of the global population and 37 percent of the global economy agreed to scale up the low-carbon bioeconomy, and develop collective targets prescribing the contribution of sustainable bioenergy to final energy demand, and as a percentage of transport fuel use. The decision is set out in a declaration released by the Biofuture Platform member countries, titled “Scaling Up the Low Carbon Bioeconomy.” It is a major breakthrough for sustainable biofuels and the broader bioeconomy, which will now become a key component of the global solution to climate change.
ADBA National Conference – London, 7 December 2017
November 22, 2017 – With the Brexit negotiations underway and the new Government committed to reducing carbon emissions, the ADBA National Conference will address the key role that anaerobic digestion (AD) can play in meeting the UK’s 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, now in its ninth year, will discuss how we can optimise the AD industry to reduce emissions through the 2020s.
US college turns to anaerobic digestion to reduce carbon footprint
November 22, 2017 – A college in Vermont, US, is aiming to reduce its carbon footprint by producing renewable natural gas from food waste and manure. Middlebury College has entered into a partnership with Goodrich Family Farm in Salisbury, Vermont, Vanguard Renewables of Wellesley, Massachusetts and Vermont Gas. The new agreement will see Vanguard Renewables construct, own and operate a facility at Goodrich Family Farm which combines cow manure and food waste to produce renewable natural gas.

How do you build a digester for a biogas plant?
November 23, 2017 – Today we’ll be your guide in discovering the building stages of a digester for a biogas plant. Watch the video that a Biogas Channel viewer has sent in! When fully developed, this biogas plant will process 1,050,000 tons of agricultural bioproducts and organic waste and produce more than 33 mio Nm3 (equivalent to 45,4 MW) of biomethane per year to be injected into the Danish gas grid. The plant is expected to be operational in 2018.

Bioenergy combined with CCS will help UK to transition to low-carbon energy economy, expert says
November 23, 2017 – Bioenergy technologies combined with carbon capture and storage (CCS) can play a significant role in the UK’s future UK energy system, according to Energy Technologies Institute (ETI) strategy manager for bioenergy Hannah Evans. The ETI is a UK-based company formed from global industries and the UK government. It was formed in 2007, but its programme is officially ending at the end of this year. The ETI showcased its ten years of innovation at a two day conference in London from 21-22 November, 2017.
