First generation bioethanol, or conventional bioethanol, is produced from the substrates of agricultural raw materials (low purity juice or syrup). Advanced ethanol is produced from the residues from sugar or starch production. By its very nature this ethanol does not compete with any food production. On the contrary it is the complement of the production of a staple food.Tereos actively participates in numerous research projects for the production of ethanol for the future.
Methods of use (in France)
Direct incorporation is already commonplace for bioethanol or ETBE (ethyl tertiary butyl ether), which is produced from a combination of bioethanol (49%) and isobutylene (51%). This is supported by French regulations.
E85 super-ethanol, which can be used in Flex-Fuel vehicles (which run just as well on bioethanol, petrol or a mix of the two), is a fuel which is 85% bioethanol and 15% petrol. More than 500 French service stations supply this fuel.
SP95 – E10 is a fuel containing up to 10% of bioethanol. In France, more than 5,000 service stations distribute this fuel, launched in April 2009. Almost all cars introduced after 2000 are compatible with SP95 - E10.
Bioethanol produces co-products that are rich in energy (beet pulp, sugarcane bagasse) or protein (brewer's grain), which can be used in animal feed instead of imported soybean cake.
Research and Development
Tereos is committed to the research and development of bioethanol for the future through multiple projects:
- The Futurol project aims to develop a technique for producing second-generation bioethanol from vegetable matter such as straw or wood (ligno-cellulose material). Tereos will introduce an industrial prototype in its factory in Bucy-le-Long in Aisne, France.
- Biocore, a European project in the FP7 Program, aims to develop a complex biomass plant-based refinery, offering various channels for the primary and secondary processing of cellulose and hemicellulose through bioconversion into ethanol and other biomolecules, as well as basic products for the chemicals industry.
- The Probio3 project aims to conduct research into the production of oils through a fermentation process, for use in the production of biofuel, jet fuel, for the aviation industry, or as a substrate for oleo-chemistry, in addition to nutritional uses (omega 3 or omega 6).
- In terms of advanced bioethanol, Tereos is working towards having the bioethanol produced from sugar or starch residues recognized as ‘advanced’ bioethanol. In fact, this bioethanol does not compete with food production.
