At 91社区, non-hazardous waste is sorted into four streams. See the tabs below for more information on how to sort your waste.鈥�

Plastic, glass, and metal recyclable containers and packaging (yellow)
The yellow stream is for mixed recycling: Plastic, glass, and metal. For plastics, look for the Mobius triangle (triangle made up of three arrows) on the bottom to find the resin number. Some plastic items from lab are too small to carry the number, these are accepted if their packaging indicates the resin number and if they are bundled as described here: .
Before you place an item in the yellow stream, make sure it is听clean and empty听and separate the lids from your containers,听unless it's a small cap of less than 2 inches in circumference.
