Perspectivas e aplicações de resíduos agroindustriais/agrícolas na obtenção de produtos de maior valor de mercado

Abstract

Daily tons of waste, agricultural and industrial, both are dropped on the ground, landfills, rivers or applied to rude energy production processes, assaulting the environment. Alternatively, in actuality these residues have been valued as a source of raw material in different processes. In particular are the waste lignocelulosicos, formed mainly of cellulose, lignin and hemicellulose are rigid structures and resistant, present promising applications such as production of pulp in paper production, alternative media as material adsorbent of heavy metals or other contaminants in waste water treatment, base ligands in industry segments, brick and cement aggregates, production of biogas and bioenergy given its calorific capacity and efficient decomposition and rich materials in units of carbon, nitrogen, calcium, needed in the use of these as a substrate in the production of micro-organisms or enzymes. Not only Brazil, due to extensive agricultural production, consequently a wide production of waste, but also different countries and its researchers have invested in research with the purpose of transforming this industrial waste into products with higher added value. . Thus, the aim of this work is to present a brief review about perspectives and applications of agroindustrial/agricultural wastes in getting the highest market value of products.
