A Synergy Between Sustainable Solid Waste Management and the Circular Economy in Tanzania Cities: a Case of Scrap Metal Trade in Arusha City. 坦桑尼亚城市可持续固体废物管理与循环经济的协同作用——以阿鲁沙市废金属贸易为例

The increased demand for secondary materials, particularly scrap metals, in cities due to development activities in both emerging economies and developing countries has increased the demand for recycling materials. It accelerated the growth of the circular economy and climate-smart development. This paper investigated the synergy between sustainable solid waste management and the circular economy in Tanzanian cities by examining the scrap business's categories, quantity, market, and nature and the scrap business's environmental benefits in Arusha. The study found that iron steel, cast iron, and aluminum were the most common scrap metal recovered and traded in Arusha. Offices and institutions, households, and garages were the primary sources of scraps. Over 314 tonnes of scrap metal were traded monthly in the city. The scrap business helped the steel industries save 300 tons of iron ore, 164 tons of coal, and 64 tons of bauxite while lowering their monthly energy consumption by 56%. Scrap metal trade contributes significantly to recycling, climate-smart, circular economy, and improving livelihoods. As a result, we call for a synchronized sustainable development and solid waste management system that connects product design, development manufacturing, and end-of-life products to improve the circular economy.

由于新兴经济体和发展中国家的发展活动,城市对次级材料,特别是废金属的需求增加,增加了对回收材料的需求。加快循环经济和气候智能型发展。本文通过考察阿鲁沙的废品业务的类别、数量、市场和性质以及废品业务的环境效益,研究了坦桑尼亚城市中可持续固体废物管理与循环经济之间的协同作用。研究发现,钢铁、铸铁和铝是在阿鲁沙回收和交易的最常见的废金属。办公室和机构、家庭和车库是废料的主要来源。该市每月的废金属交易量超过314吨。废钢业务帮助钢铁行业节约了300吨铁矿石、164吨煤炭和64吨铝土矿,同时降低了56%的月能耗。废金属贸易对回收利用、气候智慧型循环经济和改善生计做出了重大贡献。因此,我们呼吁建立一个同步的可持续发展和固体废物管理系统,将产品设计、开发制造和报废产品联系起来,以改善循环经济。
