Anaerobic Digestion of Dairy Manure in the US
The anaerobic digestion of dairy manure in the US is on a rising growth curve. Increased demand to lessen the environmental impact of fossil fuels has sparked significant interest in renewable fuels like biogas. Indeed, several US policy recommendations and rules in the areas of energy, the environment, and agriculture have been developed in the […]
Biomethane Versus Natural Gas – Demand Grows for Renewable Biogas
I was recently asked to comment on the use of “biomethane” vs “natural gas”, almost as if the two were in competition with each other. This, at one and the same time, both surprised me and impressed me. The available quantity of supply of biomethane (renewable natural gas) is very small compared with natural gas […]
Biogas in Estonia – Gas Network Operator AS Eesti Gaas Awards Work to Envitech Biogas
Biogas in Estonia is moving forward. German company Envitec Biogas has entered the Estonian market with orders for three biogas upgrading plants, in not much over 12 months. The company marked its debut into the country with a double order for its Envithan gas upgrading facilities. Both units will be extensions to existing biogas facilities. […]
What is Methane Stripping of Landfill Leachate?
Methane Stripping of Landfill Leachate refers to the removal of dissolved methane from landfill leachate before it is directly pumped to a public sewer. If the methane dissolved in leachate was allowed to enter the sewers it may be present in sufficient concentrations to cause an explosion and/or asphyxiation risk within the sewer into which […]
Biomethane Potential Test Laboratory Procedures and Services
Appointing a Biomethane Potential Test Laboratory for any proposed biogas plant feedstock is an important early step in an anaerobic digestion plant project. In this article, we discuss the biomethane potential (BMP) test, which is a biological test to evaluate the potential methane/biogas volume generated from a feedstock. The biogas produced using the standard biogas test […]
How Biogas Can Be A Replacement for Fossil Fuels in Sub-Saharan Africa
Biogas can have a central role in the replacement of fossil fuels in Sub-Saharan Africa and in providing affordable and clean energy as identified in the 2030 UN SDG 7. Uniquely, biogas has a role in: Environmental Security: being a cleaner fuel by far than the burning of fossil fuel so air pollution is reduced […]
Rice Straw Biogas – How to Make Clean Fuel from Rice Crop Residues and Decarbonise
Rice straw biogas production is a proven technology that is still completely untapped. Around 300 million tonnes of waste rice straw is burnt in fields across Asia every year. Rice accounts for 48% of all greenhouse gas emissions from crops globally, or 1,000 MT of CO2e/yr. Straw burning is producing smoke so thick it can […]
US Moving Forward Act Can Boost Biogas Industry in $1.5 Trillion Plan to Rebuild American Infrastructure
As part of the COVID-19 recovery, the US Moving Forward Act has been published amid the welcome news that, if passed by the House of Representatives, the act would at long last, bring the support for the US biogas industry in-line with the sort of tax incentive support which has long been available to some […]
What is Biogas? A Beginners Guide – Home to Commercial Digester Systems
We answer the question: “What is Biogas?” Biogas is generated during anaerobic digestion (AD) when microorganisms break down (by eating it) organic materials in the absence of air (or oxygen). Biogas is mostly methane (CH4) and carbon dioxide (CO2), with very small amounts of water vapor and other gases. The carbon dioxide and other gases […]
Biogas Tax Credits Announced for US AD Project Starts This Year
Biogas Tax Credits have been passed by Congress for Anaerobic Digestion (AD) projects which start development this year. At last the US seems to be beginning on the road toward reducing the imbalance in automatic tax subsidies still paid to the oil, coal and gas industries. Farmers across the US have a surplus of organic […]
