1 - Anaerobic Digestion Gaining Popularity and Development Momentum
As the technology improves and the process gains acceptance, announcements of new projects are becoming quite commonplace.
That’s great news for the environment, and the team at American Organic Energy is thrilled to be part of this innovative and important movement.
2 - An Anaerobic Digester Fit for a Queen?It’s true. The Royal Family in London, England recently jumped on board the trend, too, announcing several energy efficient initiatives. In addition to installing solar panels and ground source heat pumps, Buckingham Palace is looking to construct an anaerobic digestion unit to generate fuel from its organic waste.
According to its estimates, these efforts “would reduce carbon emissions by an estimated 554 tons a year.”
It’s hard to top an announcement like this from one of the most prominent figures on Earth, but the Queen isn’t the only one throwing her hat—eh, crown—into the ring. via A D Gaining Popularity
3 - Tips on using anaerobic digestate as a fertiliserUsing anaerobic digestate to feed arable crops can save farmers up to £110/ha on bagged fertiliser costs. However, there are many rules on its application in the UK.
Getting it wrong will not only bring the risk of being on the wrong side of the law, but it can also have adverse affects on soil and the environment, such as reduced earthworm numbers when applied at too high a rate.

4 - World’s first poultry litter anaerobic digester up and running
Located at Tully near Ballymena, Stream BioEnergy and its partners received the go-ahead for the plant in June of 2016. The facility first went into production in 2017. via PoultrylitterAD
5 - New Patent Air products and Chemicals Inc. - Methods For Using Ozone To Enhance Anaerobic Digestion
It has been found that ozone may also be used to enhance anaerobic digestion by converting difficult to biodegrade compounds into more easily biodegradable compounds. Ozone may be used in this way to enhance biogas production from anaerobic digestion. For anaerobic digestion of sludge, it is theorized that the ozone lyses the cell membranes, thereby exposing the more easily biodegradable cytoplasm of the bacteria.
Fermentation waste, often called vinasse, can contain compounds such as phenols that are toxic to the anaerobic bacteria and other larger carbon-based compounds that are recalcitrant.
Pretreating this feed with ozone will reduce or eliminate the toxic compounds and make the larger compounds more biodegradable, thereby reducing the required residence time in the digester.
In an anaerobic digestion process, it is undesirable to have excess oxygen present because the oxygen reduces the methane (CH4) yield by promoting aerobic digestion.
Accordingly, there is a need for an improved method of recovering un-reacted oxygen from an ozone-generation process so that the effluent may be efficiently used for an anaerobic digestion process, while maintaining high efficiency in the ozone-generation system. via Ozone-FreePatentsOnline
