Although recycling is a viable alternative to minimizing the impacts of the Municipal Solid Waste (MSW), identification of the local recycling market is a requirement for its empowerment. This paper aims to assess the recyclable solid waste market in 16 cities of Brazil. Through the application of interviews, field research and secondary data collection this research observed that while relying on poor infrastructure and on Government subsidies, the 12 pickers organizations surveyed can deliver 18.53% of recyclable waste to recycling with an average sorting productivity of 109 kg/picker/day and average earnings of US$ 293.40/picker/month. Based on the validated methods, 17% of these organizations were classified as having average efficiency, whereas 82% of them operated with very low efficiency. The investment required for the adequacy and expansion of the sorting capacity of waste pickers' organizations has been estimated at US$ 2.5 M, which could be counterbalanced by the savings with the current US$ 2 M/year spent with the disposal of recyclable waste into landfills. We also estimate new 189 job openings in the pickers' organizations to meet the requirements of the proposed scenario, contrasting with the current 93 cooperative members currently formalized. Regarding the consumer market, only few recycling companies were identified in the region, which may justify the low price paid for waste. The market for recyclables is mostly composed of micro and small companies that generally carry out the collection, transportation, sorting, and commercialization.
尽管回收是减少城市固体废物(MSW)影响的可行替代方案,但确定当地的回收市场是增强其能力的要求。本文旨在评估巴西 16 个城市的可回收固体废物市场。通过应用访谈、实地研究和二手数据收集,本研究观察到,虽然依赖于薄弱的基础设施和政府补贴,12 个拾荒者组织可以将 18.53%的可回收废物回收利用,平均分拣生产率为 109 公斤/拾荒者/天,平均收入为 293.40 美元/拾荒者/月。基于验证的方法,这些组织中有 17%被归类为具有平均效率,而 82%的组织效率非常低。为使拾荒者组织的分类能力达到适当和扩大规模,所需投资估计为 250 万美元,这可以通过当前每年用于将可回收废物倾倒到垃圾填埋场的 200 万美元节省来抵消。我们还估计,为满足拟议方案的要求,在拾荒者组织中需要新增加 189 个工作岗位,而目前正式组织的合作成员只有 93 个。关于消费市场,该地区只发现了几家回收公司,这可能解释了废物价格较低的原因。可回收物市场主要由微型和小型公司组成,这些公司通常进行收集、运输、分类和商业化。
