ROJAS-GONZALEZ, Andrés Felipe; FLOREZ-MONTES, Ciliana  and  LOPEZ-RODRIGUEZ, Diego Fernando. Use prospects of some agroindustrial waste. Rev Cub Quim [online]. 2019, vol.31, n.1, pp. 31-52. ISSN 2224-5421.

Agroindustrial wastes are a type of biomass generated mainly by organic materials processing, which come from animal handling, plant cultivation and fruit and vegetable processing. The aim of this paper is to propose possible alternatives to use 19 wastes generated in the Colombian agroindustry by fruit processing. These alternatives of use are formulated based on the waste physicochemical characterization, which was carried out through proximate analysis, ultimate analysis, analysis of structural carbohydrates and extractives compounds, total phenolic compounds content and antioxidant capacity. It was found that most of the wastes can be used as raw material in thermochemical processes. It was also found that the coffee grounds have the greatest alternatives of use, which goes from co-combustion with mineral coal to obtaining secondary metabolites.

Keywords : waste; use; carbohydrates; extractives; antioxidants.
