This naturally occurring bit of microbiological alchemy has long been utilized for energy production on farms in Asia, and as far back as the 1890s, biogas was recovered from sewage treatment facilities and used to fuel street lamps in England. However, only in the last 25 years or so have serious attempts been made to fully develop a technology of anaerobic digestion to treat liquid and solid waste streams from farms, municipalities and industry. also see http://cat.inist.fr/?aModele=afficheN&cpsidt=2482211"
