You can't manage what you can't measure: The potential for circularity in Grenada's waste management system

摘要: Abstract Can a small island state be sustainable? Small islands often suffer from myriad of sustainability challenges owing to their remoteness, size, dependency on imports, and limited waste absorption capacity. Most imports end up as accumulation in dumpsites at the life-cycle, representing one-way material flow. The concept “circular economy” (CE) is promising resource management strategy for nations improve solid management. In CE, continually circulated within economy. This study uses flow accounting (MFA) quantify deposits Grenada, tri-island, Caribbean (population: 110,874). Like many islands, Grenada has result materials open persistence illegal dumping. We estimated that generated 46,097 tonnes or 1.14 kgs per capita day 2017. Leveraging disaggregated trade data, we quantified three problematic streams: plastics, tyres, motor oil demonstrate an approach conducting MFA data-poor environments. Based results, opportunities decrease production by implementing circularity measures. recommend improving data collection, implementation polluter pays principle, banning substitutable, materials, developing plans materials.
