canadian biogas development, biogas from sewage - Metro finds way to boost energy output from sewage: Fat and grease from slaughtered animals is now helping generate more biogas at Metro Vancouver's Annacis Island sewage treatment plant.

The methane-rich gas is so far burned to generate electricity for the plant in Delta, but could in the future be cleaned and sold into the natural gas distribution grid to heat local homes.
