Anaerobic Digestion and Biogas News and Developments

Image text: "Biogas Scrubber Proprietary Technologies GWE provides two proprietary technologies for efficiently desulfurizing a biogas stream, as well as traditional activated carbon filters for tertiary polishing of the gas when very low H2S levels are required. AtmosPower's Biogas Scrubber is available in two stages for efficient gas cleaning and removal of any impurities that could irreversibly damage the critical equipment downstream of the Biogas Scrubber. In cases where the Hydrogen Sulfide (H2S) content exceeds the standard limit, a Biological Chemical-based Hydrogen Sulfide (H2S) Scrubber can be provided as part of the upgrade package. AtmosPower provides its advanced gas desulfurizing unit, which employs various grades of activated carbon to irreversibly absorb H2S and prevent it from flowing downstream with the gas. Amine absorption and a pressure adsorption column are two other common biogas purification techniques.".

How to use Biogas Scrubbers to Purify Biogas

How do you purify biogas? It’s a question central to all but the most simple use of biogas at low pressure from a home digester when it is piped direct to a kitchen stove, although even then bubbling the gas through water is often applied. According to the literature, biogas processing entails the most effective […]

List of Food Waste Depackaging and Separation Equipment Suppliers

The following is a list of “Food Waste Depackaging and Separation Equipment Suppliers”. The list is based upon our online search for, as far as possible, a complete list of global manufacturers/ suppliers of depackaging and separation machinery designed to treat mixed biowaste waste streams for the purpose of reuse and recycling in the anaerobic […]

Food Waste Separators with Less Destructive Depackaging & Pulping Pre-treat SSOHW Better

Prior to anaerobic digestion, new food waste separators with advanced depackaging and pulping technology, when used to pre-treat Source-Separated Organic Household Waste (SSOHW), improve the purity of the organic pulp. Reject output streams were also purer than for earlier systems based on milling and shredding. That’s according to research by the Department of Environmental Engineering, […]

Pig Farm Anaerobic Digestion – Realities of Operating Swine and Hog Digesters

Pig farm anaerobic digestion and including in this swine, and hog farms have just as much potential as Dairy Farms for anaerobic digestion to make biogas as an additional source of income. At the same time, their biogas plants can provide for a much more environmentally beneficial means of disposing of the farm waste, and […]

Small-scale Digestate Separator for Dairy Farms with up to 150 Cows

A small-scale digestate separator has been added to the popular Börger Bioselect™ range of digestate separator units. This adds to their range which has become a top choice for operators seeking solid/ liquid digestate separation. Virtually all AD plant operators would be assisted by this technology at the outlets from their biogas reactors. Press Release […]

Anaerobic Digestion Cost – Plus Gate Fees and Other Rules of Thumb

In this article, we look at how much does anaerobic digestion cost in general. We also discuss the gate fees that food waste digesters charge and other general rules of thumb to help those that seek help with assessing biogas digester costs. Capital Cost A commercial microbial anaerobic digester can cost anywhere between $400,000 and $5,000,000 […]

Anaerobic digester mixer by Landia Helping YW

Anaerobic Digester Mixer by Landia Helping Yorkshire Water to Net-Zero Carbon by 2030

Two anaerobic digester mixer systems recently supplied by Landia are helping Yorkshire Water to progress with carbon emissions savings toward their target of Net-Zero carbon emission across the company by 2030. High levels of biogas yield are also being achieved which indicate that these digesters are being well-mixed. Read more about the use of this […]

Sewage sludge digestion ofwat investment opportunity

Sewage Sludge Digestion – Ofwat UK Rule Changes Allow Outsourced Treatment

Five years ago, in this article, we announced that sewage sludge digestion would be put out to tender as an outsourced service by many, or all UK water companies. The opinion we gave was that there would be big opportunities from Ofwat for companies to take sewage sludge and co-digest it. We looked forward to […]

Biogas Buses – What are they? and How are they Environmentally Friendly?

Biogas buses are catching on. What could be better than using biogas from the anaerobic digestion process to power transport fleets? The energy source is renewable, made from waste by-products, and the methane used in this fuel is clean-burning. Using it instead of using a fossil fuel like diesel removes the concerns for air pollution […]
