    Over the years, studies have shown that rapid population growth and the growth of urban centers result in the substantial increase in the amount of wastes generated hence the demand for a sustainable collection system.This research aims at evaluating haul container system of waste collection in Enugu Municipal which comprises 10 zones with the view of determining the zone with higher efficiency and better cost. The data for the research was obtained through the ten zone collection crews, questionnaires (through random sampling) and oral interview. The result indicates that there is problem of unregulated waste dumping, as a result of ineffective waste collection and inadequate number of waste bins in the said zones. The weekly operational cost of the haul system in the zones as obtained from the analysis carried out are N72,000, N71, 000, N66, 000, 62,000, N60, 000, N59,000 and N58, 000 for Emene, ( New Haven and Agbani Road), ( Independent layout and Coal Camp), GRA, (Trans-Ekulu and Ogui) Achara-Layou t andAbakpa respectively and the efficiency of the collection crew in the zones are also 88% , 83%, 78%, 73% and 68% for Abakpa, Achara- Layout , (Trans-Ekulu, GRA and Ogui Road), ( Independent layout and Coal Camp) and ( Agbani Road, New Haven and Emene) respectively. Therefore the haul container system of waste collection can be improved by provision of the required basic infrastructural amenities by Government through the waste management agency (ESWAMA).

    Optimization Of The Adsorption Process In Landfill Barrier Using Response Surface Methodology (Rsm)
    (IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE), 2024-04-17) Asogwa E.O; Adie D. B; Ibrahim F.B; Amadi. A.A; Saidu M; Adesiji A.R; Mangey J.A
    Response Surface Methodology was used to examine the percentage of heavy metal removal from a sanitary landfill site utilising a lateritic soil-geopolymer composite. By Using the model, the lateritic soil geopolymer composite's adsorption potential was enhanced. The applicability of the employed model to predict the adsorption state is supported and confirmed by the good agreement between the observed and anticipated values of the removal efficiency. The applied models showed that all three of the components examined had an impact on the removal of heavy metals from sanitary landfill liners, but that the effects of dosage and contact time were more pronounced and had a substantial impact on the removal % of heavy metals. With dosage and contact time proving to be the most relevant of the three independent variables, the ANOVA findings show that the model parameters are significant. After refining the replies, the following settings proved ideal: dosage of 10g, contact time of 48 hours, and temperature of 50 °C. These yielded percentage removals of lead, zinc, and copper of 97.88%, 94.36%, and 99.48%, sequentially.
