Tom Szaky, the chief executive and founder of TerraCycle, imagines a world where shoppers take their trash with them to the grocery store. In his vision, people purchase products like ice cream and deodorant in reusable containers. At the cashier, they pay an additional cost: a refundable packaging deposit. They return empty containers to the store, which collects them for cleaning and reuse. The consumer gets each deposit back and buys another tub of ice cream or stick of deodorant from the shelf. The cycle starts again. Soon Mr. Szaky is going to find out if his idea can work in the real world. Retailers including Kroger Co. next year plan to make space in stores for Loop, TerraCycle’s refillable packaging platform. Tesco PLC in the U.K. and Carrefour SA in France also are planning to install in-store Loop “corners”—areas of a store designed for products packaged in Loop’s containers—in the next 12 months. Loblaws Inc. in Canada and Woolworths Group Ltd. in Australia will bring Loop stations to stores sometime in 2022, a Loop representative said. Aeon Co., Japan’s largest supermarket group, plans to introduce Loop corners to 16 stores in the greater Tokyo area next March. “We want people to come in and fall in love with these really cute, beautiful packages, understand the message and get excited about it,” said Satoshi Morikiyo, general manager of  convenience goods at Aeon. “Shopping trips are not necessarily something people look forward to, but this is a cool experience that offers something of a discovery—something new and fun.”
