Dome on the hill
RUTLAND, Mass.--It's not a common site on farms but the domed silo on this hill is an anaerobic digester, which will produce biogas through naturally occurring bacteria. The biogas will be siphoned of and used as a fuel for an electricity generator. It's part of a project among five farms in western Massachusetts to reduce manure waste and make power on site with the digester. This first one is going up at the Jordan Dairy Farm where the owner expects to feed enough surplus electricity to the grid to power 2,000 homes and earn him some additional revenue. The biogas will be made when bacteria digest cow manure and food waste which will be shipped in.
