Sorting It Out Game

What is This?

This is a game made by the Office of Sustainability at the University of San Francisco. It is designed to teach the player the basics of sorting waste in San Francisco, based on the current recycling and composting guidelines.

Keep in mind that, while this game is a useful educational tool for learning how to sort waste into the three primary bins, there are other types of waste (electronic waste, bio-hazardous waste, etc) that are not represented in the game. If you are unsure about where to put an item, a quick online search or email to the Office of Sustainability can easily remedy the situation.

It is also worth noting that many items are better reused than recycled. Always look for ways to use old items for a new purpose, or (if the item is in good condition) donate it to a charity.


How to Play


Once in the Main Game scene, you can sort items either by dragging the image of an item into its corresponding bin or pressing the numbers ‘1’, ‘2’, or ‘3’ which correspond to compost, landfill, and recycling respectively.

After completing a game, don’t forget to submit your score!
