Biomass is the organic non-
fossil material of
biological origin, collectively. For example,
plants (including
trees) and
animals are biomass, as are materials they produce, such as animal droppings and wood. Biomass is sometimes burned as fuel for
cooking and to produce
electricity and heat. Biomass used as fuel often consists of underutilized types, like chaff and animal waste.
In some industrialized countries, like Germany, paradoxically, food is cheaper than fuel compared by price per joule. Someone demonstrated a central heating unit supplied by food grade wheat.
