It means the end of mixing all recyclables in one container for pickup. Instead, residents must sort them into separate rollcarts with pickups on alternating weeks for items dubbed “rigids” such as plastics, aluminum cans and metals, and for “fibers” such as paper and cardboard.

No glass will be accepted curbside. The city and Meridian are finalizing plans for four locations where glass can be dropped off to be recycled, Vujnich said.

Residents will pay 50 cents more a month for basic trash service.

By converting some customers to dual-stream recycling, Meridian has been able to identify “additional processors of specific recyclable materials” at more cost-effective rates than those offered by the only single-stream processor in the market, the company said in a statement Thursday.

“Most importantly, by dividing the recycling into dual stream we are able to address contamination and, with our customers’ care and assistance, create a cleaner recycling stream resulting in more materials truly being recycled as opposed to collected and then, unfortunately, disposed of due to too much contamination and no processor willing to accept the material for recycling,” the statement said.
