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 […]

Biogas Production Improved from Wastewater Treatment Works Thickened Sludge

Biogas production improvements that raise the yield of methane from any given quantity of biomass fed into an anaerobic digestion plant are the holy grail of AD. The one thing which, above all else, is holding back on the development of anaerobic digestion is the current level of profitability which, while viable for many businesses […]

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 […]

Biogas Plant Substrate Mixing During Fermentation Creates a Stir with AD Plant Operators

The importance of “creating a stir” in the fermentation tanks of fully mixed bio-reactors for better biogas yields, and improved process stability, is becoming better understood by many AD plant clients around the globe, as more Anaerobic Digestion Plants are being built and the biogas industry matures. A scan of world news on this subject revealed that […]

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? as used in AD Plants

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 […]

NVP Energy’s Low Temperature Anaerobic Digestion (Lt-AD) Is Set To Reduce TE Charges

Low Temperature Anaerobic Digestion – The Third Type Of AD Process I was intrigued to see a newcomer with a stand at the AD & Biogas Association Exhibition and Conference 2014 last month at the NEC Birmingham.  NVP Energy was there to present their unique and innovative low temperature (< 20°C) Anaerobic Digestion (Lt-AD) wastewater (WW) treatment technology […]

Improving Biogas Plant Efficiency – Why Ferrous Chloride Not Ferric Chloride is Best

When seeking to improve biogas plant efficiency understanding why Ferrous Chloride Not Ferric Chloride is Best an be important. At the start of my recent enquiry, the expert from Lukeneder helped by explaining the differences between Ferrous Choride and Ferric Chloride. I think that my reaction of confusion, as I looked at the Lukeneder brochure just before that, […]

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 […]
