UK biogas development expands rapidly
The U.K.’s National Non-Food Crops Centre has announced the country is now home to more than 100 anaerobic digestion (AD) systems that are not affiliated with the water treatment industry. The quantity of these AD plants has more than doubled in the U.K. since September 2011.
The NNFCC estimated that the U.K.’s nonwater industry AD plants currently process up to 5.2 million metric tons of food and farm waste annually with an electric production capacity of 88 MW. According to the center, more than a dozen additional AD plants are currently under construction.
Nearly half the AD plants currently operating are community digesters, while approximately 40 percent process agricultural feedstocks, such as slurry, manure, crops or residues. The remaining digesters are found on industrial sites and take in waste materials, including food process waste and brewery effluent.
