From Farm to Plug. Biomass is the process of converting organic waste into power.
The term biomass refers to plant materials and animal waste used primarily as a fuel source. Biomass is organic matter such as wood, forest waste, or plant material used to produce energy. Biomass is considered a suitable source of renewable energy and bio-based products due to its organic nature, carbon stability, and plentiful supply.
Biomass can reduce dependence on foreign oil through the production of biofuels and give a boost to agriculture and forestry by turning low-value waste into valuable fuels, fertilizers or chemicals, and electricity. Biomass can reduce dependence on foreign oil, as biofuels are the only renewable liquid fuel available for transport.
The by-products of most industries, including timber, agriculture, natural forest waste, household waste, and landfills, are viable biomass energy sources. In the wood and paper industries, biomass is used in combined power plants to process heat and generate electricity for their own needs. The electricity sector uses waste wood and biomass to generate electricity for sale to other industries
Biomass energy (“bioenergy”) is the energy generated by a material biologically derived from a living or recent organism (animal or plant). Biomass is a general term used to describe any organic material or resource derived from plant or animal matter and is used primarily as a fuel. Biomass is a non-fossil organic material of biological origin (plants and animals) used as raw material for the production of biofuels.
Biomass does not include organic materials converted into fossil fuels such as coal, oil, or natural gas through geological processes. Biomass can be directly converted to electricity through electrochemical (electrocatalytic) oxidation of materials. Biomass can be used to generate electricity and can also be converted into liquid fuel for cars, but this page is about thermal energy applications. Biomass includes a wide variety of “fuels,” from wood and food waste to panic bars and algae specialized for fuel.
When it comes to energy, organic matter such as wood, forest waste, or plant materials can be turned into a sustainable energy. Because organic matter can be replaced relatively quickly, biomass is considered a renewable energy source. Unlike other renewable energy sources such as wind or solar energy, biomass energy is stored in the body and can be harvested when needed.
In an anaerobic environment, biomass decomposes to form methane, a valuable energy source. When biomass rots or burns, it releases large amounts of methane and carbon dioxide. On the other hand, biomass releases carbon dioxide, primarily balanced by the carbon dioxide captured in it. When used, this carbon permanently replaces carbon in fossil fuels used, for example, in heat generation and baseline power generation, in areas where it is uneconomical or impossible to use intermittent energy sources such as wind, electricity, or solar energy.
Biomass energy proponents say that when forests are cut sustainably, and wood thinning is used as fuel, smokestack emissions are neutralized by the carbon sequestered by forest regrowth. This industry argument argues that CO2 emissions from burning biomass don’t affect the atmosphere because plants can grow back or are still dead and decaying. If politicians are trying to claim “sustainability” to guarantee the carbon benefits of forest biomass, they are barking up the wrong tree. Thus, “sustainable” or “environmentally sustainable” forestry practices may benefit timber management or ecosystem/wildlife protection but cannot be taken as evidence that biomass harvested for energy production is suitable for carbon.
However, for the Earth to effectively continue the Earth’s carbon cycle, biomass materials such as plants and forests must be grown sustainably. Carbon-rich biomass can be harvested to produce heat, steam to generate electricity, or converted into oil or gas. Biomass used and burned for energy production can take many forms, from compressed wood pellets used in power plants that have switched from coal to biogas and biofuels liquid fuels that can replace fossil fuels in transportation. Biomass is a term that covers several types of organic materials that can be recycled and burned for energy, including trees, construction, wood, and agricultural waste (such as corn husks, rice husks, peanut shells, grass clippings, and leaves); collected; sewage sludge; and manure.
Biomass feedstocks include specialty energy crops, crop residues, forest, algae, wood processing, household, and wet waste. Biomass energy is only a viable solution if it uses appropriate raw materials such as waste from factories and agriculture or sustainably grown perennial crops. Biomass is especially harmful to the environment when forest biomass – trees – is burned to generate electricity.
Converting biomass to pellets (as opposed to wood chips or larger briquettes) can increase the energy density of the fuel and make shipping more profitable. On the other hand, when raw wood chips (45% moisture content) are used, this woody biomass emits 9% more CO 2 than coal for the same heat produced.
Therefore, EASAC proposes that the EU adjust the EU sustainability criteria so that only renewable energy sources with a carbon recovery time of fewer than ten years are defined as sustainable, such as wind, solar, wood waste biomass. Tree thinning, which are otherwise in this case, burn or decompose relatively quickly, and biomass from short turnover growth.
