DSNY Waste Characterization 2023 - Subsort Results

The NYC Department of Sanitation (DSNY) conducted the 2023 Waste Characterization Study in the Fall of 2022 and Spring of 2023. The 2023 Study determined the waste composition of several major sources from which DSNY collects: residential households, New York City Public Schools, the New York City Housing Authority (NYCHA), and on-street litter baskets. Waste from these generators was categorized into 96 main material categories. In addition to the 96 sort categories, certain material groups were further subsorted into 826 subsort categories which are provided in this dataset by residential strata and time period. Because not all the main material categories were subsorted, there are two separate datasets — one for the main sort results and one for the subsort results. Results for both datasets are presented in absolute terms as the quantity by weight of each material type, per stream. The quantity of each material is calculated by applying the percent composition to the total quantity of specified DSNY collections.

纽约市环境卫生局（DSNY）于2022年秋季至2023年春季开展了2023年度废物特性研究。本研究确定了DSNY所收集的几个主要来源的废物组成，包括住宅家庭、纽约市公立学校、纽约市公共住房管理局（NYCHA）以及街头废物收集箱。这些产生者的废物被分为96个主要材料类别。除了96个主要分类外，某些材料组还被进一步细分为826个子分类，这些子分类按照住宅层级和时间段提供在本数据集中。由于并非所有主要材料类别都进行了细分，因此存在两个独立的数据库——一个用于主要分类结果，另一个用于子分类结果。两个数据库的结果均以绝对值形式呈现，即每种材料类型的重量，按流道计算的数量。每种材料数量的计算是通过将百分比组成应用于DSNY指定的总收集量来完成的。
