''For domestic heating purposes the main biomass fuel is wood in the form of logs, pellets or wood chips – although there are boilers available that burn a range of cereals. The full range of biomass fuels also include animal, food and industrial waste and high energy crops such as miscanthus, willow, rape and maize.'' (National Energy Foundation)
