Lehman College Sustainability

Recycling and Composting at Lehman College

Large NYC/NYS entities are in a position to recycle larger and more varied source-separated recycling streams than that are residential settings. Large NYC/NYS entities generate large quantities of goods and materials that can be either reused whole or as parts/components, or broken down for recycling. Such streams (which go beyond mixed paper and metal/glass/plastic containers) are good candidates for reuse and recycling.

The different types of materials recycled at Lehman College are described in the table below. Some of the materials are recycled through the NYC Department of Sanitation, whose recycling program continues to evolve to include new recycling streams. Lehman College also uses contractors to dispose of certain recycling streams for which no public option exists (yet).

The City University of New York prepares an annual report (compiling data from all CUNY Colleges) to New York State Department of Environmental Conservation (Executive Order No. 4) that quantifies recycling and sustainability activities of CUNY as a whole. The quantities of each recycling/composting stream at Lehman College is given in the table below:
