Liquid Waste Management in Nigerian Brewery: A Perception Based Study

Abstract

Wastes disposal and management has remained a huge challenge for city managers in the face of rapid urbanization as is evident in most African cities. In Nigeria, this has presented serious environmental problems in recent years. The study examined residents’ perception on the effects of liquid waste on the environment, whilst gauging these perceptions with the analysis of water samples from the brewery’s point of discharge, neighbourhood surface and ground water to determine physicochemical quality using pH, Bio-chemical Oxygen Demand, and content level parameters. The study revealed that Ibadan brewery possesses an effluent treatment plant for treating liquid wastes being generated. Nonetheless, the physicochemical properties of the water sampled show that surface water was contamination of by brewery effluent. Also, respondents believe liquid waste from the brewery affects the water quality of the community. The study recommended that management of industries adhere strictly to environmental regulations guiding waste management.
