Recycling Questions & Answers

What is Dartmouth’s Waste Centralization program?

The Waste Centralization program is a system for collecting trash and recycling from offices, classrooms, and conference rooms. The program focuses on heightening individual awareness of how much trash is produced and maximizing recycling habits. With this program there are centralized locations for collecting recycling and trash, and employees carry their trash (in small, plastic containers) and recyclables to that central location.

The Waste Centralization program, in partnership with Casella, uses the Zero-Sort™, or single-stream, approach to recycling. Mixed paper, cardboard, aluminum cans, glass, and plastic are all collected in one container, and then processed by specialized equipment at the recycling center in Rutland, VT

What do you mean by “solid waste”?

Solid waste refers to all the trash and garbage that Dartmouth generates. It includes all of the recyclable items, plus things like plastic food wrappers that can’t be recycled. Dartmouth’s Waste Centralization program aims to improve the rate of recycling and decrease the amount of solid waste thrown out, thus diverting more from the landfill.

What’s the difference between “zero sort” and “single stream” recycling?

Both terms describe a method of recycling where paper, cardboard, plastic, glass, and aluminum cans are co-mingled as they are collected. Dartmouth works with Casella Waste Systems to recycle these items, which are separated by hand and machine at a facility in Rutland, VT.

Can I recycle food packaging, napkins or empty pizza boxes? Should I rinse cans and bottles?

Items with lots of food residue, napkins and paper towels should go in the trash, not the recycle bin. However, pizza boxes with a few crumbs are okay to recycle. The plastic “clam shell” take-out containers should be lightly rinsed or wiped. Bottles and cans should be empty; there's no need to rinse them out. Dartmouth recycles #1-7 plastic.
