Cornell University’s R5 Operations – Reduce, Reuse, Recycle, Rethink, Respect – manages the Ithaca campus' non-hazardous waste and recycling system. R5's overarching goals involve reducing overall waste, increasing the campus waste diversion rate, and ensuring regulatory support.

Every day, Cornell ensures clean, healthy surroundings for our community to thrive in while protecting the planet, our prosperity, and academic purpose. From food to electronics to energy, Cornell is working hard to keep reducing until we hit and maintain carbon neutrality.
