摘要

适当的废物管理是环境可持续性的基本关键。本研究介绍了尼日利亚埃邦伊州阿巴卡利基市的城市固体废物管理和处置方法。还调查了这些废物的特点和组成以及与管理有关的环境问题。在政府指定的废物倾倒场和大都市主要街道上的空地上,固体废物堆积量最高的地区,随机抽取人口进行问卷调查,以获取原始数据。通过在研究地区的口头访谈和实地观察,对不可持续的废物管理所产生的环境和健康问题进行了评估。结果表明:主要街道上的指定和非指定垃圾场和若干露天场所长期无人看管,导致垃圾堆积;侵占道路,从而限制道路使用者的通行,造成严重的空气污染问题,被风吹过会造成严重的滋扰,并扭曲大都市的美观。结果还表明,大都市的废物组成是不均匀的,因为它包含生物可降解和不可生物降解的材料,如电子废物、塑料、聚乙烯材料、医院废物和发型师废物等。该研究强烈建议让埃邦伊州环境保护局(埃邦伊州环境保护局)履行其职能,同时政府应大力考虑采用“废物转化为能源”的办法,以遏制废物管理的威胁,同时解决国家的能源需求。

Management and Disposal of Municipal Solid Wastes in Abakaliki Metropolis, Ebonyi State, Nigeria
Proper waste management is a fundamental key to environmental sustainability. In this study, the municipal solid waste management and disposal methods in Abakaliki Metropolis, Ebonyi State, Nigeria is presented. The characteristics and composition of these wastes and the environmental issues associated with its management are also investigated. Structured questionnaires were used to obtain primary data from a random size of population in the areas that have the highest accumulation of heaps of solid wastes in the Government designated waste dumping sites and open spaces on the major streets within the metropolis. Environmental and health issues arising from the unsustainable management of the wastes were assessed from oral interviews and field observations in the study areas. The results indicates that the waste dump sites (designated and non-designated) on the major streets and several open spaces are left unattended for long periods such that the rubbish heaps; encroach on the roads thereby limiting the road users access, generate serious air pollution issues, constitute significant nuisance when blown over by winds, and distorts the aesthetic view of the metropolis. The results also show that the composition of the wastes in the metropolis is heterogeneous because it contains both biodegradable and non- biodegradable materials such as e-wastes, plastic, polythene materials, hospital wastes, and hair designers wastes amongst others. The study strongly recommend that Ebonyi State Environmental Protection Agency (EBSEPA) be made to sit up on their functions while Government should strongly consider introducing "waste to energy" as a way of curbing the menace of waste management and simultaneously solving the energy needs of the State.
