摘要

目前人口的迅速增长和城镇的扩大产生了大量的废物,这需要更多的基础设施、机构设置和社区参与管理。然而,大部分产生的固体废物仍未收集,直接倾倒在空地上。本研究的重点是确定固体废物的种类、废物产生率、管理做法和城市固体废物管理服务。通过简单的随机抽样技术,从镇上的三个家庭中抽取样本受访者,按家庭总数的比例收集数据,得出了这一结果。结果显示,样本受访者产生的废物类型是有机物、塑料、纸和剪贴板、金属和其他废物(灰烬、皮革和电子废物)。城镇平均固体废物产生率为0.304公斤/人/天。该镇没有公认的废物收集或最终处置场所。社区常见的处理方式依次为沟渠(44.95%)、田间(20.7%)、路边(24.2%)、农田(3.5%)和焚烧掩埋(4.5%)。然而,大约2%的受访者不知道从家里出来的垃圾最终被处理到哪里,因为他们是由非正式的拾废者运送的。因此,当务之急是准备倾倒场地,并建立妥善处理城镇废物的机构设置。

Solid Waste Generation Rate and Management Practices in the Case of Chiro Town, West Hararghe Zone, Ethiopia
The current rapid increase in population together with expansion of the town is producing large volumes of wastes, which demand greater infrastructure, institutional setup and community participation for its management. However, most of solid wastes that generated are remaining uncollected and simply dumped at open space. This study focused on identifying the types of solid wastes, waste generation rates, management practices and municipal solid waste management service of Chiro town. The results were based on the data collected from sample respondents that drawn from three kebeles of the town, proportional to total households through simple random sampling techniques. The result revealed that the types of wastes produced by sample respondents were organic matter, plastic, paper and clipboard, metal and others wastes (ash, leather and e-waste). The average solid waste generation rate of the town is 0.304 kg/capita/day. In the town there is no recognized prepared place either for the waste collection or for final disposal. The common disposal places used by the community were ditch (44.95%), local field (20.7%), road side (24.2%), farm land (3.5%) and burning-burying (4.5%). Yet around 2% of the respondents do not know where the wastes come out of their home finally disposed to as they deliver it by informal waste pickers. Therefore, its top priority to prepare the dumping sites and establish institutional setup for proper handling of the waste in the town.
