A general classification of the pretreatment methods into three groups may be undertaken: chemical, physical und biological pretreatment methods. These feedstocks can be converted to energy, transportation fuels and renewable chemicals. The focus is on the technology for the production and use of biogas. The reason is that the cellulose (source of C6 sugars such as glucose) as well as hemicellulose (mainly source of C5 sugars such as xylose) is not accessible to the traditional bioethanol producing micro-organisms. One of the essential elements in the economical and efficient production of cellulosic biofuels is the development of biorefineries. Globally, biofuels are most commonly used to power vehicles, heat homes, and for cooking, apart from powering home boilers. Accompanying energy problems in different parts of the world, another problem that is assuming critical proportions is that of urban waste accumulation. A high proportion of the nutrients remain in the liquor, which can be used as a liquid fertilizer. The largest potential feedstock for ethanol is lignocellulosic biomass wastes, which includes materials such as agricultural residues (corn stover, crop straws and bagasse), herbaceous crops (alfalfa, switchgrass), short rotation woody crops, forestry residues, waste paper and other wastes (municipal and industrial). Biochemical conversion utilizes bacteria and enzymes to break down biomass molecules. A high proportion of the nutrients remain in the liquor, which can be used as a liquid fertilizer. Biochemical conversion of biomass includes the use of bacteria, microorganisms, and enzymes for the breakdown of biomass into gaseous or liquid fuels, including biogas or bioethanol.

Waste-to-energy is the use of combustion and biological technologies to recover energy from urban wastes. A variety of fuels can be produced from waste resources including liquid fuels, such as ethanol, methanol, biodiesel, Fischer-Tropsch diesel, and gaseous fuels, such as hydrogen and methane. In anaerobic conversion, biomass is put in anaerobic digesters, where it is exposed to microorganisms in the absence of oxygen and allowed to decay. The combustible fraction of the waste is converted into high-energy fuel pellets which may be used in steam generation. The main advantage of the microbiological processes is the mild process conditions (similar to biogas production); also, the low sensitivity of the microorganisms towards sulphur decreases the gas cleaning costs. Biogas can be used to produce electricity, fuel, or renewable natural gas. The increasing clamor for energy and satisfying it with a combination of conventional and renewable resources is a big challenge. Additional information on anaerobic digestion and fermentation can be found inNew and Emerging Conversion Technologies: Report to the Legislature, June 2007. In direct hydrogen fermentation, the . The three major steps involved are pretreatment, enzymatic hydrolysis, and fermentation. High moisture feedstocks, such as food waste and green waste, are generally good candidates for biochemical processes. Pyruvate, the conjugate base, CH3COCOO, is an intermediate in several metabolic pathways throughout the cell. However, depending on the source of biomass, the route of conversion to biofuel and the type of biofuel, the series of processes can alter. Biochemical processing produces such co-products as succinic and acetic acids (among the ingredients for biobased polymers) and other materials. The most popular biochemical technologies are anaerobic digestion (or biomethanation) and fermentation. The fiber, which can be processed into compost, is a bulky material with low levels of nutrients and can be used as a soil conditioner or a low level fertilizer. Once deconstructed, the xylan polysaccharide produces the five-carbon sugar xylose. Combined heat and power (CHP) or cogeneration systems, ranging from small-scale technology to large grid-connected facilities, provide significantly higher efficiencies than systems that only generate electricity. Major processes involved in the biochemical production of biofuels are biomass handling, biomass pretreatment, hydrolysis, and fermentation. One of the essential elements in the economical and efficient production of cellulosic biofuels is the development of biorefineries. Anaerobic digestion is a reliable technology for the treatment of wet, organic waste. wood chips) or energy crops (miscanthus, switchgrass, etc). Lignin represents a residue in the sugar fermentation system for ethanol production, as microorganisms can metabolize only sugars (which form cellulose and hemi-cellulose) but not aromatic alcohols (which are the main component of lignin). The three main routes for biochemical conversion are: 1) Anaerobic/Aerobic Digestion It offers economical protection against corrosion and a surface suitable for powder coating and painting. The most common technique for producing both heat and electrical energy from household wastes is direct combustion. These fuels are made by a biomass conversion in three different ways: thermal conversion, chemical conversion, and biochemical conversion. The feedstock is then partially oxidized, or reformed with a gasifying agent (air, oxygen, or steam), which produces synthesis gas (syngas). The liquid and solid digestate from AD may be suitable for use as a compost product, soil amendment or as a liquid or dry fertilizer.
