Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]
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 ...
Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial bio waste .
The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. [3]
Pellet fuels (or pellets) are a type of solid fuel made from compressed organic material. [1] Pellets can be made from any one of five general categories of biomass : industrial waste and co-products, food waste , agricultural residues , energy crops , and untreated lumber . [ 2 ]
Biomass to liquid (BtL or BMtL) is a multi-step process of producing synthetic hydrocarbon fuels made from biomass via a thermochemical route. [ 1 ] Main processes
Biofuels are not just limited to liquid fuels. One of the often overlooked uses of biomass in the United States is in the gasification of biomass. There is a small, but growing number of people using woodgas to fuel cars and trucks all across America. [4]
[1] [2] Conversion of biomass to liquid fuels is preferred as an alternative to the extraction of fossil fuels because biomass removes carbon dioxide from the atmosphere as it grows through photosynthesis. When combusted, this carbon is re-released into the atmosphere, closing the carbon cycle and making biofuels carbon neutral under some ...
