Fuente: WIPO "tomato" The present invention relates to a process for manufacturing a biodegradable composite. The process comprises the following steps: a) providing a bio waste selected from a group comprising a brewery spent grain, food production waste, used ground coffee and composition thereof; b) dewatering of provided bio waste; c) shredding of provided bio waste into pieces; d) drying the shredded pieces until a moisture level into the piece is down to 3-7%; e) grinding of dried pieces into smaller particles so that a size of the particles is less than 350 to 100 micrometres; and f) blending grinded particles with polybutylene succinate in result of which a biomaterial composite is formed, wherein the biomaterial composite comprises 10 to 50 % by weight the grinded particles and 50 to 90 % by weight of polybutylene succinate.
