High Rate Anaerobic Digestion Plant Treats Wastewater Effluent Streams

A High Rate Anaerobic Digestion Plant can treat high strength Wastewater Effluent Streams including sewage sludge, very efficiently. This is an important finding due to the fact that biodegradable wastewaters contribute about 6% of all anthropogenic methane emissions. High-rate anaerobic digesters have the potential to treat such wastewaters while also creating renewable energy. This energy […]

Egg Shaped Anaerobic Digesters – Strange Looking Tanks Explained

Egg Shaped Anaerobic Digesters; Enormous eggs! Whatever next! Have you ever wondered what those huge “strangely other-world like” not quite “spherical” tanks are that you sometimes see? They are anaerobic digestion process digesters, and very useful they are too! They make sewage sludge much more wholesome and in particular they reduce sludge odour, but best […]

Quick Test for Inhibitors in Biogas Substrates – New Weltec Biogas Inhibition Test Progress

A quick test for identifying inhibitors in Biogas Substrates is badly needed by the commercial biogas plant industry. Existing methods such as the Diary Farmer’s “Aerobic Plate Count” inhibitor test are not directly applicable to anaerobic biogas conditions, so a New Biogas Inhibition Test Method is badly needed. A major biogas plant systems provider WELTEC […]

Anaerobic Digestion of Manure – Technology Breakthrough! – AD Plant Productivity Doubled In Tests

Anaerobic Digestion of Manure: There has been a breakthrough in the throughput of manure-fed AD Plants! A new pre-treatment process development by Ductor™, raises new hope for super-efficient on-farm manure fed biogas plants. The Problem With Anaerobic Digestion of Manure Almost all organic materials such as manure are good feedstock materials for biogas production. Farm manures, […]

Anaerobic Digestion UK Capacity Enough to Power 1 Million Homes – Future Doubts Continue

In the UK anaerobic digestion capacity has grown rapidly to the point that the energy supply is large enough to have significance (and could power a million UK  homes if that was it’s sole use), but unexpectedly steep government subsidy reduction has thrown the future of the industry back into doubt. This was the overwhelming […]

Anaerobic Digestion Gas to Grid – Severn Trent Minworth Biogas First to Grid in UK

Severn Trent Water, are a major water and waste utility situated in the middle of the UK and a leader when it comes to delivering Anaerobic Digestion gas to grid. They run their operation from the Midlands. They serve the area around Birmingham, and also out into Wales. A major part of their business that […]

UK Brexit to Hit UK On-Farm Anaerobic Digestion While US AD Grows

The UK Brexit from the EU is about to hit UK on-farm anaerobic digestion. What has been a growing success story for the UK is being predicted to quickly become a victim of the UK government’s plans for the exit of the nation from the European Union. Other sectors, such as the anaerobic digestion of […]

Electricity Demand Response and the Anaerobic Digestion and Biogas Industry

Electricity demand response is being adopted in many countries to help electricity companies cope with the fluctuations in supply which are inherent in most renewable energy technologies except for anaerobic digestion. Anaerobic digestion with its high up-time and 24/7 power production capability, is not a part of this problem. In fact, anaerobic digestion, with its […]

Biowaste Feedstock Availability Set to Rise – EU Parliament Report

There is nothing like an EU target imposed in all member states to produce additional biowaste feedstock supplies, which are the life-blood for anaerobic digestion plant operations. Like it or lump it, and as we know, the UK doesn’t like it and will presumably be out before this comes into force. However, there are new, higher, […]

Why I Had to Look Twice at Weltec’s 2nd Biogas Plant in South Korea

When I received the press release which follows below, from Weltec I read the title quickly and took it to mean, that their new biogas plant was only the second in all of South Korea. Korea is an advanced nation I thought! How can that be correct? Yes. I was Wrong! Of course it isn’t […]
