Until now, researchers making biogas from the
\nanaerobic digester at the University of Guelph\u2019s
\nRidgetown Campus have been using liquid manure to
\nfeed the operation. Their next step is to add other materials,
\nsuch as used oil or grease from fast-food restaurants or
\nfood processing activities. In Ontario, there is currently only one operating anaerobic
\ndigester on a farm, while in Germany there are almost 4,000. In
\nseveral European countries, farmers are allowed to add other
\nmaterials to the manure in their anaerobic digesters. For example,
\nsome farmers are permitted to put up to 20 per cent of
\norganic materials obtained outside the farm into their digesters.
\nAdding this amount of these materials might lead to a doubling
\nin the output of methane, Fleming notes.
\nProducts like spent oil from restaurants can\u2019t be digested on
\ntheir own. However, blending the oil with pig manure should
\nresult in a boost in gas production. This small addition of product
\ncould result in double or triple the gas output, depending
\non the material being added.
\nAlong with mixing the pig manure with fats and oils,
\nresearchers will try using corn silage or vegetable waste from
\ncrops high in sugar, such as sugar beets or sweet potatoes<\/p>\n","protected":false},"excerpt":{"rendered":"
