Item Sustainable Water Utilisation In Ghanaian Breweries: Current Practices And Prospects(University of Ghana, 2020-05) Atiegah, R.R.Water is extremely essential for all life forms and their very existence. It is a fundamental necessity for livelihoods, economic growth, health and development and environmental sustainability. In the brewery sector, water is the single most important used raw material for production and cleaning purposes, Nonetheless, given the alarming nature of climate change, water pollution, population dynamics and land use evolutions, the brewery industry faces an enormous business risk as the diminishing of freshwater volumes pose a threat to its business continuity. Thus, breweries require a strong commitment to cleaner production processes that hinge on sustainable water management practices for continuous production. This study investigates the patterns and current trends in sustainable water use, opportunities for optimizing water use and organizational commitment to sustainable water management using sur\'e) data from the two main breweries in Ghana for the 2015 to 2018. Using 48 monthly specific water use data from January 2015 to December, 2018. the specific water usage for both ABL and GGBL are statistically significantly different from the international benchmark value of 6.50hL/hL at the I% level although, ABL's average water use has a stronger significance or is more sustainable over the study period than GGBI's average water use. Furthermore, the average specific water usage for both ABL and GGBL are compared with the best technology level of 4.00hL/hL and test results reveal that during the period under consideration, ABL's average specific water usage of 4.45hL/hL is statistically significantly different from the best technology level of 4.00hL/hL whiles GGBL 's average specific water usage is not statistically significantly different. Thus, considering water use at the best technology level of 4.00 hL/hL, GGBL is more sustainable than ABL. The study recommends collaborative partnerships between the brewery industry and government agencies that will lead to the development of sustainable water usage index or a local benchmark that factors local challenges and standards for monitoring water usage in the local economy.
