背景塑料产量的大幅增加导致了塑料在环境中的扩散,随后海底塑料沉积并被海洋动物摄取。迫切需要监控家庭消费中管理不善的塑料垃圾。家庭支出调查分析量化了家庭包装(瓶装或袋装)水消费产生的管理不善的塑料垃圾,但不是来自其他产品的消费。方法为了评估家庭支出调查是否可以量化来自其他广泛消费的商品的管理不善的废物,我们使用两个家庭支出调查对加纳城市大阿克拉和全国所有城市的家庭食用油和包装水产生的管理不善的塑料垃圾进行了量化。结果根据调查得出的估计表明,在大阿克拉,包装水产生的塑料垃圾比石油包装产生的多得多,而在肯尼亚城市,石油包装产生的塑料垃圾比包装水产生的更多。结论通过成功地将调查分析方案从包装水转移到食用油,我们的结论是,支出调查有很大的潜力在国际上用于量化家庭中管理不善的塑料垃圾。然而,需要考虑到影响管理不善的废物估计的不确定性。
Backgroundsubstantial increases in plastic production have resulted in plastics proliferating of in the environment, with subsequent seabed plastic deposition and ingestion by marine fauna. There is an urgent need to monitor mismanaged plastic waste from household consumption. Household expenditure survey analysis has quantified mismanaged plastic waste generated from household packaged (bottled or bagged) water consumption, but not from consumption of other products.Methodsto evaluate whether household expenditure surveys can quantify mismanaged waste from other widely consumed commodities, we quantify mismanaged plastic waste from the domestic consumption of cooking oil alongside packaged water in urban Greater Accra, Ghana, and all cities nationally in Kenya using two household expenditure surveys.Resultshousehold survey-derived estimates indicate packaged water consumption generates considerably more plastic waste than oil packaging in Greater Accra, whereas oil packaging generates more plastic waste than packaged water in urban Kenya.Conclusionby successfully transferring a survey analysis protocol from packaged water to cooking oil, we conclude that there is ample potential for expenditure surveys to be used internationally to quantify mismanaged plastic waste from households. However, uncertainties affecting mismanaged waste estimates need to be accounted for.
