Urban biowaste, a sustainable source of bioenergy?

"Although most bioenergy is produced by burning agricultural and forestry biomass, it is also generated by burning the organic parts of municipal solid waste, biowaste or urban biomass. This includes food waste from restaurants, households, farmers markets, gardens, textiles, clothing, paper and other materials of organic origin. But have you ever tried to fuel a bonfire with a salad? Probably not, so this may not be the most efficient use of urban biowaste."
