摘要

Method for obtaining a solid fertilizing and biocombustible product from sugar-cane vinasse and solid fertilizing and biocombustible product obtained by means of said method, which allows optimum utilization of resources and high energy efficiency throughout the method in addition to a solution to managing the waste constituted by vinasse, comprising a step A that consists in concentrating liquid vinasse (1) to obtain concentrated vinasse (2) with a solids percentage of at least 50%, a step B that consists in mixing the concentrated vinasse (2) with plant compounds (3) and a step C that consists in granulating the mixture obtained in step B to obtain a granular solid product (4) that can be used as fertilizer (4') and as biofuel (4'').
