Many of P&G’s largest global brands, including Tide, Cascade and Crest, will participate in the circular e-commerce sustainable platform, the company says in a news release. Developed by Trenton, New Jersey-based TerraCycle, the platform will collect and recycle items, including toothbrush heads and razor blades, “creating circular solutions that help eliminate waste.”

Loop was announced in January by recycling specialist TerraCycle, whose CEO Tom Szaky recently said: “Plastic is not the evil. The evil is using something once.” Pilots launched this week in the northeastern United States, with Kroger and Walgreens as new partners, and in Paris, with another planned later this year in the United Kingdom. With any luck, this new approach to product packaging will catch on and become a new normal for many of our everyday products.

Loop, a first-of-its-kind circular shopping system created by TerraCycle in partnership with major retailers and brands, on May 21 officially launched its pilot program in the Mid-Atlantic region of New York, New Jersey, Pennsylvania, Maryland and Washington, D.C. To celebrate the launch, TerraCycle and Loop’s retail and brand partners held a press conference and reception at the World Economic Forum in New York City.

When consumers sign up for the pilot–either through a new platform called Loop or through Kroger or Walgreens (you can also add your name to the wait list if you live elsewhere)–the products will arrive at their house in a reusable shipping tote, , and then someone can schedule a pickup to send the packaging back to be sterilized and reused. In theory, it’s not much more difficult than throwing out single-use packaging. Despite the extra shipping, Terracycle, a recycling company that is one of the partners in the project, has calculated that the carbon footprint of the process will be far less than that of typical packages. Because the products involved in the pilot are large brands, the companies testing the idea are hoping to reach a larger audience than some niche refillable concepts already on the market.
