Sorting It Out: Waste Sorting Basics

Proper waste sorting is one of the simplest actions you can take to tackle climate change on a daily basis – and Stanford is dedicated to making sorting easy and stress-free for everyone. Most of what is used daily on campus can be either recycled or composted. Follow these simple rules to sort your waste properly and contribute to a wasteless community.

Be Risky with Recycling

If it is plastic, metal, glass, paper, or cardboard, throw it in the blue bin. Unsure? Take a responsible risk – Stanford has robots to help!

Scrape out food scraps and dump out liquids first. How clean does it need to be? When you turn it upside down and nothing falls out, it’s ready for the blue bin!

Be Careful with Compost

All food scraps, napkins, paper towels, and packaging labeled “compostable” can be composted. Most campus cafes use compostable serviceware. If it looks like plastic, check for “compostable” on the label and toss it in the green bin!

Landfill as the Last Resort

Items like chip bags, snack wrappers, non-compostable cups, and gloves should be landfilled. Landfill material is not sorted, so only send items here as a last resort.
