Pig Farm Biogas Plant Output Increased 10% While Reducing Impact
We welcome this news that an innovative US Pig Farm Biogas Plant operator has raised its biogas output while all else remains constant by more than 10% simply by installing more efficient pumps. We have written previously on a number of occasions about these pumps. These days hardly a week goes by without another technology […]
Digestate Separator Successfully Removes Plastic Packaging Waste from AD Plant Slurry
With the massive public concern about plastics entering the environment today’s news of a new digestate separator device that successfully removes plastic packaging waste, is very good news. It removes bits of food waste packaging, and other unwanted materials from entering the digester, and from the slurry which pours out of all wet-process biogas plants […]
Use a Biogas Extruder to Make Biogas from Straw Not Food – Biomass Bioextruder™
The Biogas Extruder: Until now making biogas from straw and other similar grain crop residues has been considered uneconomic by the AD industry. But, that was before the advent of bio extrusion technology, and specifically the biomass Bioextruder™. The use of any food crops for energy production often attracts public criticism. This is despite the […]
Scottish Anaerobic Digestion Industry’s Astonishing Year of Growth 2015
Scotland’s anaerobic digestion (AD) industry has grown by nearly 70%t in the last year, according to 2015 figures.
Anaerobic Digestion & Biogas Technology Can Supply 30% Of UK Domestic Gas Demand
The anaerobic digestion story continues to become bigger as new sources of biomass feedstock are identified and the biogas technology used improves
Hydrolysis of Sewage Sludge and Anaerobic Digestion Wins
The hydrolysis of sewage sludge and the subsequent anaerobic digestion of the hydrolysed sludge output is becoming increasingly common at many sewage works. We think we are justified to call it a winning combination, and we even back up this assertion by providing information on a new contract win for the technology by Veolia, in […]
What is Biomethane and Anaerobic Digestion Gas to Grid Definition
It is a good question to ask; “What is biomethane and anaerobic digestion gas to grid”, but for the first part (biomethane) don’t expect always to get the same answer! Many people use the term biomethane interchangeably as if it means the same as biogas. In fact, when the term “biomethane” is used correctly the […]
Combined Heat and Power Systems (CHP) – 3 Important Considerations for Design
Combined heat and power systems (CHP), are also known as co-generation systems, and they greatly improve the usable energy output from electricity generation systems. When a gas engine or turbine is used to generate electricity without CHP, after the electricity leaving the site, there is also hot “cooling water” that is used to keep the […]
The Biogas Engine Defined and How it Generates Electricity
We have defined what we mean by a biogas engine and how such engines are used as a biogas generator, including discussing what cogeneration means in terms of secondary heat ultilisation and CHP
Anaerobic Digestate Disposal, or Use as a Natural Fertilizer?
The question as to whether to go for Digestate Disposal, or use it as a Natural Fertilizer is important, and not a simple one to determine. Digestate from any wet anaerobic digestion process comprises both a liquid and a fibrous solid material. As we plan Anaerobic Digestion Plants the question arises for each site as […]
UK Biogas Funding for Biofuels CHP RO FiTs and RHI – Looking Back 10 Years
To understand the historical background to policy on UK Biogas Funding for Biofuels and CHP (Combined Heat and Power Installations), RO (the now-defunct Renewables Obligation), FiTs (Feed-in-Tariff closed) and the RHI (Renewable Heat Incentive – still current but for how long?*) it is necessary to go back 10 years to 2011 and the “Anaerobic Digestion […]
Anaerobic Digestion Feasibility Study List of 10 Examples
Have you ever considered doing an Anaerobic Digestion Feasibility Study? If you are wondering about whether or not to build your own biogas plant, sooner or later most people consider embarking on an Anaerobic Digestion Feasibility Study. You can do these yourself, but generally, it is better to bring in a biogas expert to work […]
