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.

Columns
Each source column, with the name and type we use to store it.
0 of 10 columns carry a concept; 10 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
