Danisco A/S is a Danish bio-based company with activities in food production, enzymes and other bioproducts as well as a wide variety of pharmaceutical grade excipients. It was formed in 1989 from the largest Danish industrial merger ever of the two old C.F. Tietgen companies Danish Sugar, and Dansk Handels- og Industri Company.
Cellulosic ethanol is ethanol produced from cellulose rather than from the plant's seeds or fruit. It can be produced from grasses, wood, algae, or other plants. It is generally discussed for use as a biofuel. The carbon dioxide that plants absorb as they grow offsets some of the carbon dioxide emitted when ethanol made from them is burned, so cellulosic ethanol fuel has the potential to have a lower carbon footprint than fossil fuels.
A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts. The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products and bioenergy ". As refineries, biorefineries can provide multiple chemicals by fractioning an initial raw material (biomass) into multiple intermediates that can be further converted into value-added products. Each refining phase is also referred to as a "cascading phase". The use of biomass as feedstock can provide a benefit by reducing the impacts on the environment, as lower pollutants emissions and reduction in the emissions of hazard products. In addition, biorefineries are intended to achieve the following goals:
- Supply the current fuels and chemical building blocks
- Supply new building blocks for the production of novel materials with disruptive characteristics
- Creation of new jobs, including rural areas
- Valorization of waste
- Achieve the ultimate goal of reducing GHG emissions
Corn stover consists of the leaves, stalks, and cobs of maize (corn) plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop and is similar to straw from other cereal grasses; in Britain it is sometimes called corn straw. Corn stover is a very common agricultural product in areas of large amounts of corn production. As well as the non-grain part of harvested corn, the stover can also contain other weeds and grasses. Field corn and sweet corn, two different types of maize, have relatively similar corn stover.
Biomass to liquid is a multi-step process of producing synthetic hydrocarbon fuels made from biomass via a thermochemical route.
Bioconversion, also known as biotransformation, is the conversion of organic materials, such as plant or animal waste, into usable products or energy sources by biological processes or agents, such as certain microorganisms. One example is the industrial production of cortisone, which one step is the bioconversion of progesterone to 11-alpha-Hydroxyprogesterone by Rhizopus nigricans. Another example is the bioconversion of glycerol to 1,3-propanediol, which is part of scientific research for many decades.
Xethanol AMEX: XNL was one of the smaller producers of corn ethanol in the United States, and one of the few publicly traded companies developing technology for producing cellulose ethanol. Ethanol fuel will have increased production from a current level of about 5 billion US gallons (19,000,000 m3) per year to over 20 billion US gallons (76,000,000 m3) annually. Potentially 60 to 100 billion US gallons of ethanol could be produced annually in a sustainable manner from domestic biomass resources. To achieve these goals some believe it will be necessary to develop and commercialize technology for the production of ethanol from cellulose and hemicellulose. Xethanol says it plans to increase production and profitability with new technology it has under development.
The bioconversion of biomass to mixed alcohol fuels can be accomplished using the MixAlco process. Through bioconversion of biomass to a mixed alcohol fuel, more energy from the biomass will end up as liquid fuels than in converting biomass to ethanol by yeast fermentation.
The United States produces mainly biodiesel and ethanol fuel, which uses corn as the main feedstock. The US is the world's largest producer of ethanol, having produced nearly 16 billion gallons in 2017 alone. The United States, together with Brazil accounted for 85 percent of all ethanol production, with total world production of 27.05 billion gallons. Biodiesel is commercially available in most oilseed-producing states. As of 2005, it was somewhat more expensive than fossil diesel, though it is still commonly produced in relatively small quantities.
Genencor is a biotechnology company based in Palo Alto, CA and a subsidiary of IFF. Genencor is a producer of Industrial enzymes and low-priced bulk protein. The name Genencor originates with Genencor, Inc., the original joint venture between Genentech and Corning Incorporated, which was founded in 1982. It is considered to have pioneered the field of industrial biotechnology, as distinct from traditional applications of biotechnology to health care and agriculture.
Second-generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of non-food biomass. Biomass in this context means plant materials and animal waste used especially as a source of fuel.
The Food, Conservation, and Energy Act of 2008 was a $288 billion, five-year agricultural policy bill that was passed into law by the United States Congress on June 18, 2008. The bill was a continuation of the 2002 Farm Bill. It continues the United States' long history of agricultural subsidies as well as pursuing areas such as energy, conservation, nutrition, and rural development. Some specific initiatives in the bill include increases in Food Stamp benefits, increased support for the production of cellulosic ethanol, and money for the research of pests, diseases and other agricultural problems.
Range Fuels was a company that tried to develop technology for the conversion of biomass into ethanol without the use of enzymes. The technology employed was biomass gasification followed by syngas conversion over heterogeneous molybdenum-based catalysts to a mixture of aliphatic alcohols. The company began in 2006 as Kergy and changed its name to Range Fuels in 2007. The company broke ground on its first commercial-scale cellulosic ethanol facility in November 2007.
Mascoma Corporation was a U.S. biofuel company founded to produce cellulosic ethanol made from wood and switchgrass. Headquartered in Lebanon, New Hampshire, the company was founded in 2005 by Robert Johnsen (CEO), Lee Lynd and Charles Wyman, two professors from Dartmouth College. The company was named after Mascoma Lake, which is near Lebanon. In November 2014, the yeast-related business assets including the Mascoma name were purchased by Lallemand, Inc. of Montreal, Canada. The R&D facility in Lebanon, NH was renamed Mascoma LLC which is now a subsidiary of Lallemand. The remaining business assets of the former Mascoma Corp. including the thermophilic bacteria technology, pilot plant in Rome, NY, and former headquarters in Waltham, MA were renamed Enchi Corporation.
Algenol, founded in 2009, headquartered in Fort Myers, Florida, Algenol is an industrial biotechnology company that is commercializing patented algae technology for production of ethanol and other fuels. The technology enables production four of the most important fuels using a proprietary process involving algae, sunlight, carbon dioxide and salt water.
Enerkem is a clean technology company based in Montreal. Founded in 2000, Enerkem uses its patented technology to convert residual biomass and non-recyclable municipal solid waste (MSW) into biofuels and renewable chemicals.
Inbicon is a Danish company that produces cellulosic ethanol.
Cello Energy was an Alabama biofuels company beset by fraud allegations. The company proposed to produce energy from cellulosic ethanol. In 2010, the United States Environmental Protection Agency projected the company could produce 70 million gallons of cellulosic diesel before reducing their projections to 5 million gallons and then removing the company from supplier listings in 2011. Cello Energy filed for bankruptcy in 2010. In 2009, Cello Energy lost a federal lawsuit based on allegations of breach of contract and fraudulent claims, and was ordered to pay $10.4 million.
Cellulosic sugars are derived from non-food biomass (e.g. wood, agricultural residues, municipal solid waste). The biomass is primarily composed of carbohydrate polymers cellulose, hemicellulose, and an aromatic polymer (lignin). The hemicellulose is a polymer of mainly five-carbon sugars C5H10O5 (xylose). and the cellulose is a polymer of six-carbon sugar C6H12O6 (glucose). Cellulose fibers are considered to be a plant’s structural building blocks and are tightly bound to lignin, but the biomass can be deconstructed using Acid hydrolysis, enzymatic hydrolysis, organosolv dissolution, autohydrolysis or supercritical hydrolysis. A more recent mechanical method offers hope that at last, a more economic and waste free method has been found although it is still to scale and is not yet commercial.
