High Rate Anaerobic Digestion Plant Treats Wastewater Effluent Streams

By definition, a High Rate Anaerobic Digestion Plant can effectively handle high-strength wastewater effluent streams, such as sewage sludge. To be high rate it needs to be able to provide the necessary reactions at a higher rate than traditional biogas process plant which need a 30 day retention period or longer. Back in 2017, we […]

Bio Thermic Digester (BTD) Gains Acceptance And May Become Major Competitor To Anaerobic Digestion

Bio Thermic Digester (BTD) is the term for an innovative type of industrial-scale biological high temperature-digester which uses Aerobic Extremophilic Bacteria to achieve a remarkably high level of mass reduction and has been launched by waste treatment specialist Advetec. The technology is understood to be capable of rapidly processing significantly high volumes of organic municipal waste, […]

Anaerobic Digester Cost – Manure Management Projects On-Farm

How much does an Anaerobic Digester cost to construct, commission and run? That’s the vital question for AD utilisation on manure management projects on farms. If the sum of these costs is known and the price payable for the outputs in energy and biofertiliser available to any farm business they will be able to work […]

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 […]

Green Biogas – UK Green Investment Bank Backing Is Proof

We have said many times that the anaerobic digestion process makes green biogas, but where is the proof of that? We say that not only is it green in the sense of it being an environmentally friendly form of energy and fertilizer production, but it also has many other “green” environmental benefits. That green biogas […]

UK Anaerobic Digestion Plants Exceed 100 And Hit Trouble: Looking Back

Looking back at our March 2013 article when UK Anaerobic Digestion Plants exceeded 100 and we thought they were hitting trouble, by causing environmental problems. With hindsight, (in November 2019) we can see that we were wrong. Yes, of course there have been teething problems with new biogas plant owners. Some started out, not appreciating […]

Biogas GCSE – BBC Bitsize Teaching and Course Content Queries?

Anaerobic Decay, Methane Gas and Biogas Generators are all topics students learn in the UK Biogas GCSE student curriculum. Here they are discussed from the point of view of a UK biogas expert. Parents: Did you know that biogas GSCE content is being taught in UK schools?  Yes, it is. It is good news that […]

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 […]

Anaerobic Digestion of Whey – The Proven Biogas Technology Solution

Disposing of unwanted whey from commercial dairies, was once a considerable problem. But, that was before recent developments in biogas plant technology. The Problem with Whey Farmers can use only limited amounts of the nutrient-rich liquid. If they put too much of the whey on their land, the mixture will run off into nearby waterways, […]

What is Renewable Energy and How Does It Work

There is a simple answer to; “What is renewable energy?” It is energy which is self replenishing. Many people would say that it is also sustainable energy, which implies that in accordance with many definitions of sustainability it should be self replenishing within a generation, so that the present generation does not rob energy resources […]
