Adnams Brewery has completed construction of three anaerobic digesters at their distribution center.  Each digester is capable of handling 12,500 metric tons per year and will be fed brewery waste and food waste.  The resulting methane is planned for use in delivery trucks and hopefully distribution into the gas grid.  
You can find the companies press release here.
