“…Inefficient or unsatisfactory waste or effluent management has led to environmental pollution, depletion, global warming, deforestation, shoreline erosion or degradation of natural ecosystems and upon this, many potential pollutants have found their way into ground and surface waters causing harm to the environment, and also, to man, plants and animals. Industries such as breweries that uses large amount of water for processing have the potential to pollute waterways through the discharge of their effluents into streams and rivers or by run off's and seepage of stored wastes into nearby water resources [10]. Brewery plants have been known to cause pollution by discharging effluents into receiving stream, ground water and soil [9].…”

Brewery is a major industrial activity in Nigeria from which wastes are generated. The present global attention on effective wastes management in the sector has compelled the country to embrace aggressive research methods on this essential subject matter. This has therefore been the impetus for this study to use the Cradle-to-Grave section of Life cycle analysis in the ISO 14040 for investigation of improved wastes management in a Nigerian brewery. In the study, emissions associated with brewery were identified and quantified to determine the releases into air, water and land. Materials use, use of energy, wastes and by-products generation as well as physical size from the sector were also determined for wastes management. The study shows that intensiveness of energy and water consumption in brewery industry during productions could cause large emissions that may have negative effects on the environment. Agreement of the material inputs and outputs in the study at about 99.6% level indicates that the adopted method can be of great help in solving wastes management problems in the brewery.

The physico-chemical and microbial examination of Ajali River in Ezeagu Local Government Area (LGA) of Enugu State, South-eastern Nigeria, were carried out to assess the characteristics of the water for potability. Water samples were collected from three sampling points, including the one close to the brewery effluent discharge into the river and two different points that were affected by non-point sources. Altogether, eighteen samples were collected for two years during the dry, early and late rainy seasons. The physico-chemical, as well as microbial analyses of the samples, were determined following the standard methods. Significant spatial and seasonal variations (p<0.05) were clear for some physico-chemical parameters such as pH, phosphate, and sodium. Mean values of the Water Quality Index (WQI) were: dry season (104.23±9.75); early rainy season (113.22±8.78) and the late rainy season (102.58 ± 11.15). All the values are above 100 showing that the calculated WQI in all the seasons is not good however after the addition of lime, boiling and filtering to increase the quality.
