Brewing is a very energy and water-intensive process. The team has been tasked to design a microbrewery on the UBC campus with the collaboration of the UBC AMS. This report focuses on the design of a sustainable microbrewery that uses efficient methods for waste management. The reactants needed for the brewery process are yeast, hops, malt/barley grains, and water. The microbrewery is divided into two sides: the hot and cold sides. The hot side contains the mash/lauter tun and hops boiler. The mash/lauter tun is used to mash grains to convert starch to sugar and then separate wort from the undissolved spent grains. The hops boiler is used to extract flavor from hops. The cold side encompasses the fermentation tank and the bright tank. The market analysis conducted on the brewing business shows that their consumption can be almost cut in half by recycling the water and energy streams. In addition, two control loops will be implemented for this process, with simple control strategies being used due to the process being a small-scale batch process. Both of these will be temperature control loops applied on the fermentation tank (R-100) for optimum yeast metabolism and the bright tank (V-103) to keep the beer at a cool temperature before packaging. Pressure relief valves are also installed on the tanks to release any build-up pressure occurring; no further equipment protection measures are required as this is a small-scale production that will not have hazardous levels of carbon dioxide or achieve high pressures. The final design's environmental and economic analyses have been conducted, and analysis has been described in the report below. It was found that for an initial investment of $1.3M, gross revenue of approximately $350k can be expected.
