The 40-year-old singer-songwriter has teamed up with sports clothing corporation Adidas to create a capsule collection made with Bionic Yarn fabric -- cloth made from plastic debris found in the ocean.
The line will feature the brand's classic sporty apparel made with the Eco-friendly material.
"Working with an iconic brand like Adidas is such an incredible opportunity," Williams said in a statement. "From the classic track suit to growing up in Virginia wear Stan Smiths, Adidas has been a staple in my life. Their pieces are timeless. This is an exciting partnership for both me and Bionic Yarn."
Adidas announced their collaboration with Pharrell in a YouTube clip published Thursday, calling it a "long term partnership."
"I am truly thrilled to work with Pharrell. He is a pop-culture icon that never fails to inspire, not just through his musical talent and craft, but through his many other interests. He is the perfect fit for the multi-faceted company that is adidas," Dirk Schoenberger, Global Creative Director, adidas Sport Style Division said.
The products will make their debut in the summer of 2014.
