This study investigates the effect of the production processed effluence on the environment, a case study of a typical brewery industry in Nigeria. Production process effluence remains a major environmental challenge in the brewing industry. The brewing industry generates different waste that affects the environment. In this study, waste samples including spent grain, hot trub, spent yeast, and wastewater was collected and prepared. The waste samples were analysed for moisture, carbohydrate, protein, fat, fibre, ash, and energy contents using proximate analysis. The wastewater sample was analysed for pH, temperature, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total dissolved solids (TSD) and total suspended solids (TSS). The proximate analysis results showed %moisture (7.2, 9.37 & 8.82), %protein (20.16, 60.14 & 42.70), %carbohydrate (23.11, 20.0 & 36.13), %fat (6.30, 3.0 & 3.22), %fibre (38.27, 0 & 6.4), %ash (3.51, 5.43 & 2.10) and energy value (205.73, 89.25 & 246.51kcal/100g) for spent grain, hot trub and spent yeast respectively. The physicochemical analysis of the wastewater showed the value of pH (8.7), temperature (28.17oC), COD (2050.24mg/L), BOD (1247.23mg/L), TSD and TSS (255.32mg/L). Disposal of these wastes creates serious problems for the environment. Methods of mitigation include application in animal feed and biogas production, and treatment of wastewater before disposal. Integrated brewery processes for sustainable production are recommended.

Researchers have been continuously searching for the most readily available means of producing electricity without any negative effect on the environment. Renewable source of energy like solar energy, hydro electric energy, biomass and wind energy has been considered as the alternative. Wind energy among others is rated the best renewable sources of energy because it’s level of environmental friendliness. In this paper, a horizontal windmill was designed, fabricated and its performance evaluated with two types of vortices and without a vortex. The component parts of the mills are towel, blades, shafts, base, tail vain and vortex. During the design of the windmill, consideration was given to the size, area of the blade and the blade material that produce maximum speed. The performance evaluation was carried out to compare the performance of the mill with the solid vortex, gap vortex and without vortex. The result of the evaluation reflects that the solid vortices have the highest wind speed irrespective of time of the day and with an optimum wind speed of 5.04 m/s. Also, the wind mill performed at a higher efficiency with the vortex compare to when it was running without vortex.

The increase in the prices and demand for cooking fuel has necessitated the deployment of an alternative fuel (biomass wastes), which is efficient and relatively inexpensive. Biomass wastes are abundant and underutilized for energy purposes in Nigeria. The conversion of these wastes into briquettes can help to mitigate the over-dependency of wood for cooking and deforestation. In this study, biomass wastes such as rice husks (RH), banana peels (BP), coconut husk (CH), groundnut shell (GS) and saw dust (SD) were collected in various dumpsites in Abakaliki, Ebonyi State and sun dried for a week for ease of grinding. Briquettes were produced mechanically from all samples, including a mixture of all the samples (MIX) using the same ratio. Waste paper was used as a binder. Characterization analyses (i.e. calorific value, proximate and ultimate analyses) were conducted using ASTM standards. The results revealed that the MIX briquette has an average calorific value of 26346kJ/kg, 12.35% moisture, 8.99% ash, 0.05% sulphur and 34.7% carbon. Essentially, the findings revealed that the combination of the biomass wastes have a positive effect with respect to the physical and chemical properties of the MIX briquette. This fuel briquette can replace wood for cooking and mitigate deforestation.
