Waste & Recycling


Waste management is an important part of WCM sustainability efforts. Reducing the amount of trash sent to landfills can significantly reduce greenhouse gases and pollution.

At Weill Cornell Medicine, the Housekeeping team oversees the movement of our trash and recycling. Trash from the main campus is collected and consolidated in a compactor before being picked up by a hauler. WCM’s hauler provides a single-stream recycling system. This means that all recycling streams are combined together. The separation into different waste streams (paper, plastic, metal, glass) happens later at a sorting facility. Only corrugated cardboard (such as thick delivery boxes) is collected separately. However, keeping paper separated from plastic, glass, and metal helps preserve it and increase paper recycling quality. Therefore, the Office of Energy & Sustainability  encourages WCM students and staff to separate paper from the rest of their recycling when possible.

Trash and recycling from residencial buildings and some leased areas are collected by other haulers via the building manager or by the Department of Sanitation. Usually, these areas must separate paper from the rest of the recycling, and the recycling streams are collected separately by the hauler.
