A standing crop is the total biomass of the living organisms present in a given environment. [1] This includes both natural ecosystems and agriculture. See also
In the context of energy production, biomass is matter from recently living (but now dead) organisms which is used for bioenergy production. Examples include wood, wood residues, energy crops, agricultural residues including straw, and organic waste from industry and households. [1] Wood and wood residues is the largest biomass energy source today.
The Biomass Energy and Alcohol Fuels Act of 1980 is a statute that addresses general biomass energy development in its various forms, and the use of gasohol. [1] It was one of six acts enacted by the U.S. Energy Security Act. [2] The purpose of the statute is to reduce the dependence of the United States on imported petroleum and natural gas.
Standing crop biomass – Unlimited growth is an exponential process, which means that the amount of biomass determines the production. Because an increased biomass implies higher respiration per surface unit and a limited increase in intercepted light, crop growth is a sigmoid function of crop biomass.
Third, enterprises owned by agricultural producers, for the purposes of demonstrating cost-effective, cellulosic biomass innovations for feedstock preprocessing and crop harvesting, with a requirement to produce ethanol, or for another energy purpose. This section authorizes funds for the program for FY2006-FY2015.
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]
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 ...
In some instances, torrefaction of biomass may benefit the power plant if energy crops/biomass is the material the converted fossil fuel power plant will be using. [16] Also, when using energy crops as the fuel, and if implementing biochar production, the thermal power plant can even become carbon negative rather than just carbon neutral.
