DSNY Waste Characterization 2017 - Main Sort Results

The Department conducted the 2017 NYC Residential, School, and NYCHA (NYC Housing Authority) Waste Characterization Study over three seasons: spring, summer, and fall. This study builds on decades of research and analysis into the evolving composition of NYC's waste stream. The study team hand sorted samples into 70 main sort categories. Results are presented in absolute terms as the quantity by weight of each material type. The quantity of each material is calculated by applying the percent composition to the total quantity of DSNY collections for fiscal year 2017 (July 2016-June 2017).

本部门在春、夏、秋三个季节内对2017年纽约市住宅、学校和纽约市公共住房管理局（NYCHA）废弃物特性进行了研究。该研究基于数十年来对纽约市废弃物流动态组成演变的研究与分析。研究团队将样本手工分类至70个主要类别。结果以绝对值形式呈现，即每种材料类型的重量。每种材料的数量通过将百分比组成应用于2017财年（2016年7月至2017年6月）DSNY（纽约市废物管理局）收集的总量进行计算。
