Abstract
A method for manufacturing a composition consisting of brewer's spent grains and polylactic acid includes the steps of: providing a raw material containing brewer's spent grains; providing a raw material containing polylactic acid; mixing the brewer's spent grains with the polylactic acid at a specific proportion; and providing a binder to enable the brewer's spent grains and the polylactic acid to be well mixed, and to maintain a desired tensile strength. A pretreatment unit includes a dehydration process, a desiccation process, a drying process, a grinding process and a sieving process. A granulator includes a double screw extruder connected with a cutting machine. The double screw extruder mixes the PLA material and the brewer's spent grains and extrudes them into plastic bars which are then cut into plastic granules by the cutting machine.
