Biomass

Look up biomass in Wiktionary, the free dictionary.

Biological material from either living (see ecology) or recently living organisms (see bioenergy)

Biomass is a term used in several contexts: in the context of ecology it means living organisms,[1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g. only from plants,[2] from plants and algae,[3] from plants and animals.[4] The vast majority of biomass used for bioenergy does come from plants. Bioenergy is a type of renewable energy with potential to assist with climate change mitigation.[5]

IUPAC definition

> biomass: Material produced by the growth of microorganisms, plants or animals. [6]

## Uses in different contexts[edit]

### Ecology[edit]

* Biomass (ecology), the mass of living biological organisms in a given area or ecosystem at a given time. This can be the biomass of particular species or the biomass of a particular community or habitat.

### Energy[edit]

* Biomass (energy), biomass used for energy production or in other words: biological mass used as a renewable energy source (usually produced through agriculture, forestry or aquaculture methods)
* Bioenergy, energy sources derived from biological material
* Solid fuel, forms of bioenergy that are solid
* Biofuel
* Energy crops

### Biotechnology[edit]

Biomass is also used as a term for the mass of microorganisms that are used to produce industrial products like enzymes and medicines.[citation needed]

#### Bioproducts[edit]

Examples of emerging bioproducts or biobased products include biofuels, bioenergy, biochar, starch-based and cellulose-based ethanol, bio-based adhesives, biochemicals, bioplastics, etc.[citation needed]

#### Biological wastewater treatment[edit]

In biological wastewater treatment processes, such as the activated sludge process, the term "biomass" is used to denote the mass of bacteria and other microorganisms that break down pollutants in wastewater.[7]: 243 The biomass forms part of sewage sludge.

### Others[edit]

* Biomass (satellite) \- an Earth observation satellite
