Biomass is considered "sulfur-free" as a fuel for the pre-combustion capture. However, there are other trace elements in biomass combustion such as K and Na that could accumulate in the system and finally cause the degradation of the mechanical parts. [29] Thus, further developments of the separation techniques for those trace elements are needed.
The Alpena biorefinery plant in the USA. A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals). The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)".

Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. [3] Bioenergy can help with climate change mitigation but in some cases the required biomass production can increase greenhouse gas emissions or lead to local biodiversity loss. The environmental impacts of ...
Biogas is a gaseous renewable energy source [1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester , biodigester or a bioreactor .
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]
Forest bioeconomy includes, for example, the processing of forest biomass to provide products relating to, energy, chemistry, or the food industry. Thus, forest bioeconomy covers a variety of different manufacturing processes that are based on wood material and the range of end products is wide.
Agricultural wastes: Fruits, molasses, stems, plant straw, and bagasse (residue after crushing sugarcane or sorghum stalks). Industrial wastes: Food/beverage processing waste, dairy wastes, starch/sugar industries wastes, slaughterhouse wastes, and brewery wastes. [1] These are just some of the different sources that anaerobic digestate can ...
biobased products, such as food, feed, chemicals or other materials, and/or; bioenergy, such as biofuels, power or heat. A biorefinery is a facility like a petroleum refinery that comprises the various process steps or unit operations and related equipment to produce various bioproducts including fuels, power, materials and chemicals from biomass.
