Organic matter, including: agricultural and forestry residues, municipal solid wastes, industrial wastes, and terrestrial and aquatic crops grown solely for energy purposes.[1][2]

Wikipedia Definition

Biomass is plant or animal material used for energy production (electricity or heat), or in various industrial processes as raw substance for a range of products. It can be purposely grown energy crops (e.g. miscanthus, switchgrass), wood or forest residues, waste from food crops (wheat straw, bagasse), horticulture (yard waste), food processing (corn cobs), animal farming (manure, rich in nitrogen and phosphorus), or human waste from sewage plants. Burning plant-derived biomass releases CO2, but it has still been classified as a renewable energy source in the EU and UN legal frameworks because photosynthesis cycles the CO2 back into new crops. In some cases, this recycling of CO2 from plants to atmosphere and back into plants can even be CO2 negative, as a relatively large portion of the CO2 is moved to the soil during each cycle. Cofiring with biomass has increased in coal power plants, because it makes it possible to release less CO2 without the cost associated with building new infrastructure. Co-firing is not without issues however, often an upgrade of the biomass is most beneficial. Upgrading to higher grade fuels can be achieved by different methods, broadly classified as thermal, chemical, or biochemical (see below). IUPAC definitionBiomass: Material produced by the growth of microorganisms, plants or animals., e fuel can also be consumed indirectly via a fuel cell system containing a reformer which converts the biomass into a mixture of CO and H2 before it is consumed in the fuel cell., Biomass is plant or animal material used for energy bakkkk bhakkproduction (electricity or heat), or in various industrial processes as raw substance for a range of products.

It can be purposely grown energy crops (e.g. miscanthus, switchgrass), wood or forest residues, waste from food crops (wheat straw, bagasse), horticulture (yard waste), food processing (corn cobs), animal farming (manure, rich in nitrogen and phosphorus), or human waste from sewage plants. Burning plant-derived biomass releases CO2. The issue of whether biomass is carbon neutral is contested. Material directly combusted in cook stoves produces pollutants, leading to severe health and environmental consequences. Agriculture to grow the biomass products produces CO2 as well, through aeration (tilling), fertilizer, deforestation, and the supply chain. Offsetting these impacts, photosynthesis cycles the CO2 back into new crops and to the soil. The EU and UN consider biomass a renewable energy source., Biomass is a modern name for the ancient technology of burning plant or animal material for energy production (electricity or heat), or in various industrial processes as raw substance for a range of products.

Since biomass technically can be used as a fuel directly (e.g. wood logs), some people use the terms biomass and biofuel interchangeably. More often than not, however, the word biomass simply denotes the biological raw material the fuel is made of, or some form of thermally/chemically altered solid end product, like torrefied pellets or briquettes.

However, it remains the mainstream view, supported by for instance the IPCC, FAO (Food and Agriculture Organization of the United Nations) and IEA. Use of biomass in energy production is increasingly controversial, due to large-scale deforestation in low-income countries and transport subsequent transportation the wood over long distances to high-income countries to be burned in power plants in order to account for "CO2 neutral" regulatory status. Examples of such practices involve transporting forest wood from Namibia to Germany, from USA to United Kingdom, from Siberia to Poland, usually over diesel-powered marine transport and distances of thousands kilometres., Biomass is plant or animal material used as fuel to produce electricity or heat.
