Warner Music and GZ Media launch a landmark pilot with Abbey Road Studios to process unsold vinyl into new, commercial-grade pressings.

Warner Music Group (WMG) and GZ Media have completed a landmark pilot showing how unsold records can be reprocessed and incorporated into new vinyl pressings without compromising the sound quality. The pilot processed approximately 10,000 unsold records sourced across artists, titles, and pressing plants, reflecting the mixed inventory typical across the industry.

The records were then shredded, and multiple pressing variants of records were pressed using different recycled content ratios, ranging from 10 to 100%. Through rigorous blind listening evaluations coordinated with Abbey Road Studios, industry experts assessed the pressing without knowing which material blends they were hearing.

The results showed that recovered material can be successfully incorporated into new, commercial-grade pressings while maintaining the sound quality and production standards expected across today’s physical releases.

Alongside the audio testing, the project also evaluated the environmental impact of reprocessing unsold vinyl records. While reintroducing recovered material can reduce the use of virgin PVC, the process also requires additional steps such as transport, warehousing, sorting, and shredding, making it important to assess the overall net impact. Product carbon footprint (PCF) modeling indicates the potential for carbon emissions reductions of over 10% compared to virgin material baseline under the conditions assessed.

As vinyl continues its global resurgence, the collaboration underscores how coordinated innovation across the value chain—from the studio to label processing plants—can help shape the next chapter of vinyl.

“Vinyl listeners care deeply about sound quality, so the standards for this project were always high. What impressed me was how consistent the pressings were across the different material blends, showing that sustainability and sound quality do not have to be at odds,” said Miles Showell, Mastering Engineer at Abbey Road.

“Sustainability and quality must go hand in hand. For more sustainable products to be adopted across the industry, it’s important they deliver the same level of quality and performance as standard products. We hope this project provides a foundation the industry can continue to build on as it explores more resource-efficient pathways for vinyl production,” added Vladimir Víšek, Head of Sustainability at GZ.

“Innovation doesn’t always mean creating something new; sometimes it means evolving a classic without losing what made it special in the first place,” Madeleine Smith, Sr. Director ESG, WMG, concluded. “Developed in close partnership with Miriam [Lessar] and WMG’s physical audio team, we are providing that recovered material streams can drive a more responsible future for physical formats, without sacrificing the listening experience artists and fans love.”
