Abstract:

Brewing industry is one of the most power full industries though world that can produce high amount of solid waste and liquid effluents. There are four main solid waste that generated during beer production. Brewer’s spent grains (BSG), denatured protein precipitate after boiling hot trub (protein coagulation that occurs during the boiling of the wort (trub), excess yeast (microbial fermentative activity) and diatomaceous earth slurry (also known as Kieselguhr sludge) from water filtration. Due to its step-by-step process, brewing involves several processes during which waste is produced the main destination of this waste is the feeding of cattle and utilatization of those waste in to valuable product like; biopolymer production from cellulose material, yeast extraction from brewers’ spent yeast and have different advantage. If it is not properly handled it also negative impact to environment when it release un properly to environment.

Keywords: Brewer’s spent grains, Diatomaceous earth, Excess yeast, Solid waste, Trub
