This paper presents a detailed review of municipal solid waste (MSW) and resource management in Bahrain, using the recently developed UN-Habitat city profile methodology. Performance indicators involve quantitative assessment of waste collection and sweeping, controlled disposal, materials recovery and financial sustainability together with qualitative assessment of user and provider inclusivity and institutional coherence. MSW management performance in Bahrain is compared with data for 20 other cities. The system in Bahrain is at an intermediate stage of development. A waste/material flow diagram allows visualization of the MSW system and quantifies all inputs and outputs, with the vast majority of MSW deposited in a controlled, but not engineered landfill. International comparative analysis shows that recycling and material recovery rates in Bahrain (8% wt. for domestic waste, of which 3% wt. due to informal sector) are generally lower than other cities, whereas waste quantities and generation rates at 1.1 kg capita(-1) day(-1)) are relatively high. The organic fraction (60% wt.) is comparable to that in middle- and low-income cities (50-80% wt.), although on the basis of gross domestic product Bahrain is classified as a high-income city, for which the average is generally less than 30% wt. Inclusivity in waste governance is at a medium stage as not all waste system stakeholders are considered in decision-making. While the system now appears to be financially stable, key pending issues are cost-effectiveness, improving the standards of disposal and deployment of extensive materials recovery/recycling services.
本文采用最近开发的联合国人居署城市概况方法,详细回顾了巴林的城市固体废物(MSW)和资源管理情况。绩效指标涉及对垃圾收集和清扫、控制处置、材料回收和财务可持续性的定量评估,以及对用户和提供者包容性和机构一致性的定性评估。巴林的 MSW 管理绩效与其他 20 个城市的数据进行了比较。巴林的系统处于发展的中级阶段。废物/物质流程图允许可视化 MSW 系统,并量化所有输入和输出,其中大部分 MSW 存放在受控制但非工程化的垃圾填埋场中。国际比较分析表明,巴林的回收和材料回收率(8%wt.,其中 3%wt.来自非正式部门)普遍低于其他城市,而废物量和产生率为 1.1kg 人均-1-1) 相对较高。有机部分(60%wt.)与中低收入城市(50-80%wt.)相当,尽管根据国内生产总值,巴林被归类为高收入城市,而平均水平通常低于 30%wt.。废物治理的包容性处于中级阶段,因为决策中没有考虑所有废物系统利益相关者。虽然该系统现在似乎在财务上稳定,但仍存在一些关键的待解决问题,包括提高成本效益、改善处置标准以及部署广泛的材料回收/再循环服务。
