Aerobic Digestion and Anaerobic Digestion – A Comparison
Any comparison of Aerobic Digestion and Anaerobic Digestion should first explain that a comparison can be made either on the basis of either: microbiology ( the study of microorganisms) or respiration systems in man and mammals generally. In this article we compare (1) aerobic digestion with anaerobic digestion (2), in the context of microbiology and […]
The Ugly Truth About Ignoring the Benefits of a Circular Economy
Ignoring the Benefits of a Circular Economy in an attempt to sign a trade deal with the US, while ditching UK alignment with the EU, would have ugly outcomes for future generations. The circular economy is the only hope for future generations for whom the current generation must return to using no more than the […]
Waste Autoclave Pretreatment with Anaerobic Digestion for Household Waste
Waste Autoclave pretreatment of residual household waste, and food waste, for all its undoubted advantages in increased biogas yield during subsequent anaerobic digestion of the organic fraction, has met with a difficult period. The story has not been a good one, since we originally posted our article on this subject in May, 2012. In a […]
Anaerobic Digestion in the US Shows Growth Despite Low Electricity Prices
Anaerobic Digestion in the US is expanding despite no subsidies, in most cases. Many opinion-formers suggest that Anaerobic Digestion technology needs strong subsidies to have a chance of being developed to meet its potential. However, US AD site “Biocycle”, has posted an article which suggests the contrary. It says that’s not the case in the […]
Biogas Potential is Too Small to Make a Difference – Myth Busted! WBA Report Shows
How large is the biogas potential in terms of energy output? Can there ever be enough anaerobic digestion plants to really make enough of a difference to significantly reduce global carbon emissions? The answer is : Yes! Biogas’ potential is substantial. Over the years many have even said that; “It’s not possible to make enough […]
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, […]
