Industrial Waste Recovery
The Brazilian sugar–alcohol sector is known for generating large amounts of residues of sugarcane processing due to its size. Therefore, the utilization of these residues by the industry becomes necessary not only from the environmentalal point of view, but also as a way of avoiding wasting materials which may add value to the sugarcane productive chain. The search for sustainable processes and increases in gains make products that were once considered a problem in the sugar–alcohol sector to be viewed as considerable sources of income for the sugarcane plants.In this chapter the use and application of the main byproducts in the sugar–alcohol industry will be approached, as well as the use of sugarcane bagasse and straw to produce biofuels, chemical products and animal food; the use of yeasts in human and animal feeding; as well as the use of molasses, filter cake, vinasse, and carbon dioxide.
