Saying it will help make Harrisburg a "green and progressive city," Mayor Eric Papenfuse unveiled a new recycling program for glass jars and bottles Monday.

The program will launch on Earth Day, April 22. Glass jars and bottles without caps or lids will be accepted at 10 locations throughout the city, Papenfuse said.

The program won't accept other glass items, such as mirrors, window paned and drinking glasses.

Drop-off sites will be at Shipoke, Hall Manor, Kline Plaza, fire stations One, Two and Eight, the Broad Street Market, the Uptown Shopping Plaza, the public works department and William Howard Day Homes.

Glass recycling is back in Harrisburg after a nearly three-year hiatus. The city cut back stopped taking glass for recycling in 2015, citing the cost.

Papenfuse said Monday that glass is being handled separately from other recyclables this time because it can break and be difficult and expensive to remove for the rest of the recycling stream.

This time around, public works crews will collect the glass, take it to a central location and break it up, he said.
