Since the return of curbside recycling January 31, the City of Tulsa has noticed a higher-than-average number of “contaminated” recycling carts.

Most contamination has been seen in the form of plastic bags, Styrofoam, and other non-recyclable materials. Contaminated carts are not picked up and are identified with a yellow or white tag.

The city is asking all refuse and recycling customers to learn what can and can’t be recycled.

An informative video on what types of things can and can’t be recycled can be watched online.

Only recyclables allowed in the recycling stream should be placed in the blue cart. All trash should be placed in bags in the gray cart. Items items that should be included in the recycling stream including aluminum and steel cans, paper and cardboard, plastic bottles and jugs, glass jars and bottles.
