Developed by KFB Technische Anlagen GmbH, the first KFB Series anaerobic digester has been in operation on a dairy farm near the Dutch-German border since early in 2011.
This is a full-scale unit, processing the fresh slurry from over 80 cattle to generate electricity for export to the local grid, under German feed-in-tariff regulations. Proprietary features of the process and the plant make the unit cost-effective at an unusually small scale.
Following an extended period of trials, KFB is now offering the technology to other customers in the demanding German market.
KFB has now commissioned two further full-scale anaerobic digesters on dairy farms in Germany. These incorporate a number of improvements based on nearly five years of practical experience on the first unit.
The first KFB unit has featured in an extended article in the authoritative Energie Magazin, published by Top Agrar (number 4/2012), under the heading “Biogas aus der Garage”.
AAL and KFB have agreed to work together on technology developments. Based on KFB’s operating experience, AAL has developed SlurryGen, optimized for the specific economic and regulatory conditions in the UK.
