Ibrahim Karidio identified four groups of biomass sources: cellulosic materials from wood residues, agricultural crops, animal wastes, and municipal and industrial solid wastes.

“B.C. has a huge land mass,” Karidio said. Of the total provincial annual allowable cut, 47% comes from the Northern Interior. B.C. generates 31% of Canadian wood residues and 66% of Canadian surplus wood residues.

Karidio said straw and stover produces 1.8 million bone dry tonnes (BDT) of cellulosic biomass per year. Further, he said it is significant that 99,300 BDT of agricultural residues are produced annually, largely by hay and barley. But “agricultural production is not considered to be a big source of biomass in B.C.,” he said.

B.C. is responsible for 5% of the annual Canadian production of biomass from animals’ manure, with a gross revenue potential of $32 million.

Municipal and industrial wastes were estimated using data from the Foothills Boulevard Regional Landfill in Prince George. The energy value of the recyclable portion of solid wastes handled by the landfill is 705,000 gigajoules (GJ) per year. The landfill gas collected at the site has an energy value of 56,500 GJ per year. Currently, “they basically burn it,” Karidio said. “This energy could be used more usefully.”
