Dry anaerobic digestion can be seen as a well-kept secret. It is seldom mentioned in most AD industry circles. In the rush to develop anaerobic digestion plants so far, most biogas project promoters have stuck to the most familiar methods of wet anaerobic digestion. However, in many countries the profitability of biogas projects will soon […]
Anaerobic digestion and biogas news and developments, plus general informational articles on the subject.
Anaerobic digestion is turning not only cow – well you know – dung, into environmentally-friendly energy to heat and power your home, but also tannery (leather making) wastes, and even rejected chocolate.
Latest single-home anaerobic digestion unit off the shelf, turns food waste into biogas (cooking gas) and fertilizer, for under $900.
Scotland’s anaerobic digestion (AD) industry has grown by nearly 70%t in the last year, according to 2015 figures.
The anaerobic digestion story continues to become bigger as new sources of biomass feedstock are identified and the biogas technology used improves
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 […]
Biogas Tractors and the most efficient use of biogas, on the farm to provide the fuel to power the farm vehicles was simply not previously available.
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
The anaerobic digestion of kitchen waste (also known as food waste anaerobic digestion) makes a lot of sense for urban communities which culturally have always prepared a lot of their food, especially where much of it is from vegetables they prepare themselves at home. In these circumstances there is a lot of organic vegetable kitchen waste […]
There is a simple answer to the question of what Digestate is. Digestate is what remains after anaerobic digestion (biogas digestion) and it is comprised of the solid fibrous material fraction emanating from the AD bio-reactor, and the liquid portion. Anaerobic digestion draws carbon, hydrogen and oxygen from the feedstock. However, the essential plant nutrients […]
