Philadelphia music shops and D'Addario celebrate Earth Day by repurposing hard to recycle instrument strings
D'Addario's Playback program repurposes used instrument strings, which generally can't be sent to municipal recycling centers. The effort, which has collected roughly 8 million strings so far, is a collaboration with Trenton's TerraCycle, a company which recycles waste that's hard to repurpose. Russo Music, which has a Philadelphia location, is one of roughly a dozen area shops collecting strings for the program.
