  • the present invention relates to the biofuel production, agri-food and beer production sectors.
  • the agri-food industry generates the series of wastes that, if properly treated, can be used to obtain precursors of biofuels and high value-added products.

  • the brewing process requires four main ingredients, 5 water, yeast, hops and malt.
  • L malt comes from the process of malting cereal grains (usually barley). Beer brewing - consists of several stages. The first is the malt shaping, then the maceraclon stage is carried out where the ground malt is put in contact with the water, which allows the enzymes (formed during the germination) to degrade the constituents of the malt 30 ( carbohydrates and proteins) to soluble forms and then the liquid that is leaving to ferment,.-called must. Subsequently the. mos or is withdrawn mediaste pressing and filtrado- and the solid rest of this stage is dmemina bagasse 'beer. Basically it is formed by the grains and grains of the cereal.

  • Bagasse is a wet product whose dry matter content is 20-25%. There are no Sij ⁇ Ifieative differences in. The chemical composition correlated - with the dry matter content, although this is variable. In the market it receives other names like the one of beer cebadilla, and is the term equivalent to what the Anglo-Saxon world knows as "wethr wass' sgi 1 ".
  • Beer bagasse is a protein-rich byproduct, with an average protein content of 24-26% on dry matter.
  • the ethereal extract represents a fas un.
  • By-product also rich in fiber, with a FND content of 44 and FAD of 20%, although it is a very ineffective fiber (18%).
  • the lignin content is 5% and the ash content is 7%.
  • its content in phosphorus (or g kg) stands out, being lower (3 g / kg) - the content in Ca.
  • Beer bagasse is considered a residue with little interest. commercial. In the acteaUdad it is sold to the livestock sector to be used as feed for cattle and sheep mainly. This commercial outlet is common for all breweries. AND! sale price of bagasse vad according to the company. There are some that give a symbolic price, on condition that the bagasse is removed in the shortest possible time. Other laws or sales price is intended to cover the cost of transportation. It is definitive, we must say that bagasse is not a source of income and that the reason for its coming is to avoid having to carry out waste management with the consequent cost.

  • Hydrated ethanol (C 2 H 5 OH) can be used directly in conventional explosion engines and light modifications, with HEOS yields similar to those obtained are gasoline.
  • Absolute ethanol ⁇ dehydrated can be used in admixture with normal gasoline (up to 22% today), to increase the octane indico and produce lead-free snperearbnranfes, which reduce pollutant emissions. These fuels are known as the name of gasohoks and they are being used in about 35 countries (especially the United States and Brazil). Absolute ethanol can also be added to diesel for use in diesel engines (usually in mixtures of 10-15% ethanol) with the same desire to reduce pollution, this is done » for example » in Tours (France) and Sloecimo (Suet ⁇ a).

  • Bioeianol is produced, from lignocellulosic residues, by microbial fermented soluble sugars released from cellulose and bemicellulose, by chemical drolysis, (adda or basic), in emeic or microbial. It is estimated that the amount of plant residues, potentially useful for this purpose, m the world is 1.5-10.5 g / year (dry weight) whose bioethanol production, together with the 3 ⁇ 4e could be obtained from other remains of harvest could replace up to 32% of current gasoline consumption (Kan and Dale, 2004).
