More recently, the company has stepped up its conservation efforts, partnering with Terracycle, an organization that repurposes hard-to-recycle waste. Together, they formed Playback: the world’s leading string recycling program. Since Playback’s inception, D’Addario has recycled more than 3 million strings through Restring & Recycle events hosted by music retailers across the country, recycling competitor strings and rewarding D’Addario’s loyalty members for participation.
