Games Practice recycling in a fun way by playing these free online games. Help clean up the park! Your job is to sort the stuff people throw away and put it in the proper bin. Is it recycling, compost, or trash? Get facts about climate change and tips on how you can help save the earth. Learn the basics of recycling with the Litter Critters! Kids will sort trash into four different litter categories: recyclables, compost, electronic waste, and landfill waste. In Easy Mode, users sort trash into one category of litter at a time. In Hard Mode, users must sort trash into all four categories at once. There’s lots to do here – people and places to visit and plenty of ways to explore how all the city kids and adults reduce waste, reuse and repair things, recycle, and compost. Recycle City also promotes environmental justice.
