DSNY Waste Characterization - Comparative Results

The NYC Department of Sanitation (DSNY) has conducted four waste characterization studies to date: 2005, 2013, 2017, and 2023. For each study, a representative sample of waste is sorted into distinct material categories and aggregated into statistically significant data on the composition of the City's discards. This dataset contains the change in the composition of the City's waste streams across all four studies.
