Biocide

marine

A general term for substances that counter foul actively. Biocides can have very different levels of toxicity and their environmental impact can vary from nothing to significant.

Bioconversion of biomass to mixed alcohol fuels

energy

The bioconversion of biomass to mixed alcohol fuels can be accomplished using the MixAlco process.

Biodegradable waste

energy

Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes.

Biodegradation

energy

Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi.

Biodiesel

energy

Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters.

Biodiesel production

energy

Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification.

Biodiesel production feedstock

energy

Common feedstock used in biodiesel production include yellow grease (recycled vegetable oil), "virgin" vegetable oil, and tallow.

Bioenergy

energy

Bioenergy is energy made from biomass or biofuel.

Bioenergy with carbon capture and storage

energy

Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon, thereby removing it from the atmosphere.

Bioethanol

energy

Bioethanol is produced by fermenting plant-derived sugars to ethanol, using a similar process to that used in beer and wine-making.

Biofuel

energy

Biofuel is fuel that is produced through contemporary processes from biomass, rather than by the very slow geological processes involved in the formation of fossil fuels, such as oil.

Biofuels

marine

Essentially biofuels, both bioethanol and biodiesel, are derivate of vegetable oils and animal fats. In Europe, rapeseed oil methyl ester (RME) is the common feedstock. In the United States the most common biofuel...

Biogas

energy

Biogas is the result of treating organic matter in digesters or through other decomposing processes.

Biogasoline

energy

Biogasoline or biopetrol (British English) is a type of gasoline produced from biomass such as algae.

Bioliquids

energy

Bioliquids are liquid fuels made from biomass for energy purposes other than transport (i.e. heating and electricity).

Biologic carbon sequestration

energy

Biologic carbon sequestration refers to storage of atmospheric carbon in vegetation, soils, woody products, and aquatic environments.

Biomass

energy

Biomass is plant or animal material used as fuel to produce electricity or heat.

Biomass chemical conversion

energy

Chemical processes are used to convert biomass into other forms, such as to produce a fuel that is more practical to store, transport and use, or to exploit some property of the process itself.

Biomass conversion

energy

A process that upgrades raw biomass to higher grade fuels.

Biomass energy

energy

Biomass energy is energy generated or produced by living or once-living organisms. The energy from these organisms can be burned to create heat or converted into electricity.
