Biogas Production Process Dairy Farmers Selling Herds to Biodigest Grass
Biogas production from grass is a proven viable process. Today (2019) many UK dairy farmers have not only considered selling their herds, they’ve done just that. Instead of cattle for milk, they are simply growing grass for direct feed into an anaerobic digestion plant, and storing silage for winter use. This makes good sense in […]
Pipeline Quality Gas and the Benefits of Biomethane Gas to Grid
The acceptance of biogas upgrading technology which purifies raw biogas to Pipeline Quality Gas (natural gas pipeline quality) and enables AD plant operators to inject biomethane gas to grid is rising. Benefits of Upgrading to Pipeline Quality Gas Once biomethane gas to grid is accomplished, the biogas plant operator gains not only from a higher […]
Fibrous Biogas Digestate Enhancement and Treatment Techniques
The following article is an explanation of the options for Anaerobic Digestion Plant Digestate Enhancement, (Fibrous Biogas Digestate), which were reviewed by Pell Frischmann Consultants when they produced a report for WRAP in the UK, on the subject of Biogas Digestate Enhancement and Treatment Techniques, in 2012. It includes an updated background to the use of […]
How to Solve Food Waste AD Pipe Blockage Problems
At the RWM Exhibition at the NEC Birmingham, UK, last week, while I was talking to Anaerobic Digestion service providers, a recurring topic which came up was the significant number of UK biogas plants which have recently been afflicted by pipe blockages. These were in many cases proving to result in long plant outages, and […]
What is Thermal Hydrolysis? Thermal Hydrolysis Technology Explained
So you want to know; “What is the thermal hydrolysis process?” – and to understand basic thermal hydrolysis technology. Thermal Hydrolysis is a chemical process in which the organic molecules (in the substrate/ feed material) are split into two parts by the addition of a molecule of water. The process forces the water molecules between the […]
How to Reduce Methane Emissions? – By Our Support of Agricultural Biogas Says Obama
In a very welcome move, the White House is backing farm biogas production from manure and other feedstocks, as a way to reduce national methane emissions which are implicated as a significant source of climate change. The US dairy industry not only came to the same conclusion in 2009, but has been working toward its […]
