Since 2005, Grecycle works, and the Pima County Regional Waste Water Reclamation Department has put on the Annual Grease Drive. Drop-off locations are set up and staffed by volunteers, allowing residents a place to properly dispose of waste cooking oils.
The event usually happens in the first week of January, however for 2023 it will take place on
January 14th, 9am to 1pm.
Grecycle also works with U of A's Engineers Without Borders, Tuscon Earth Day, and fuel for "The Physics Factory."
