Allegheny County Council has given preliminary approval to a waste management plan that will serve the county through 2028. This is a regular 10-year update of the plan, but this time around recycling is taking center stage.

Starting Jan. 1, glass and some plastics will no longer be accepted in recycling bins in 22 South Hills communities, including Moon Township, Mt. Lebanon and Upper St. Clair. This is because a new Waste Management contract will go into effect, and the company is trying to move away from recycling glass.

Erica Deyarmin-Young, a public affairs coordinator with Waste Management, said processing glass is time consuming and expensive for the company.
