Abstract

Municipal solid waste management is one of the greatest challenges for environmental sustainability and well-being in developing countries, where the infrastructure and financial resources required to carry out such services are often lacking. The design of solutions that adequately respond to local needs must be based on quality information about the quantity and composition of the generated waste and current management practices. This study evaluated domestic waste generation and its management in 81 communities in Ecuador based on sampling at the source and population surveys. An average household waste generation value of 0.613 kg/cap/d was obtained, of which biowaste accounted for 68 % of the total generation, followed by 23 % recyclable material and 9 % other non recyclable waste. Even though some councils have set up differentiated collection systems for inorganic material in urban areas, these systems are still absent in many rural areas, which explains why waste is not separated in 70 % of the studied communities. Furthermore, only 70 % of the rural population in the country has a waste collection service, and waste in some communities is still thrown into water bodies or burned. Rural populations often use biowaste at home by composting it or as animal feed, which are good practices that should be considered in the diagnosis reports and incorporated into waste management planning.
厄瓜多尔家庭废物生产分析:当地社区可持续管理的局限性。
城市固体废物管理是发展中国家环境可持续性和福祉面临的最大挑战之一,这些国家往往缺乏提供此类服务所需的基础设施和财政资源。要设计出充分满足当地需求的解决方案,必须以有关所产生废物的数量和成分以及当前管理方法的高质量信息为基础。这项研究通过源头抽样和人口调查,对厄瓜多尔 81 个社区的生活垃圾产生量及其管理情况进行了评估。得出的平均家庭废物产生量为 0.613 公斤/瓶/天,其中生物废物占总产生量的 68%,其次是 23% 的可回收材料和 9% 的其他不可回收废物。尽管一些市议会在城市地区建立了不同的无机材料收集系统,但在许多农村地区,这些系统仍然不存在,这也解释了为什么在所研究的社区中,有 70% 的垃圾没有被分类。此外,全国只有 70% 的农村人口拥有垃圾收集服务,一些社区的垃圾仍被扔进水体或焚烧。农村人口通常在家中使用生物废物,将其堆肥或作为动物饲料,这些都是良好做法,应在诊断报告中加以考虑,并纳入废物管理规划。
