Biomass is the organic non- fossil material of biological origin, collectively. For example, plants (including trees) and animals are biomass, as are the materials they produce, such as animal droppings and wood. The most successful animal of the earth, in terms of biomass, is the Antarctic krill, Euphausia superba, with a biomass of probably over 500 million tonnes, roughly twice the total biomass of humans.
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. This is often considered a type of alternative energy although it is a polluting one.
In some industrialized countries, like Germany, paradoxically, food is cheaper than fuel compared by price per joule. Central heating units supplied by food grade wheat or maize are available.

- Stover
- BaggasseBaggasse bins take in discharge from a milling train and filters into a boiler feed conveyor. In order to permit continuous feed to the folier the bin provides surge storage capacity. External Links .
- Dried distiller's grain
- Meat and bone mealMeat and bone meal (MBM) is a by-product of the rendering industry. It is typically about 50% protein, 35% ash, 8-12% fat, and 4-7% moisture. It is primarily used in the formulation of animal feed to improve the amino acid profile of the feed. Feeding of

- SilageSilage is fermented, high-moisture forage to be fed to ruminants, cud-chewing animals like cattle and sheep. It is fermented and stored in a structure called a silo. Silage is most often made from grass crops, including corn (maize) or sorghum. Silage is
- ManureManure is the term used to refer to the droppings, dung, feces (faeces) or excrement of plant-eating mammals ( herbivores) and poultry. Mammal droppings consist of large amounts of partially digested plant material broken down into small fragments. As the
