Rethinking Recycling Efforts

While numerous initiatives exist to reduce the amount of plastic consumption in retail, there are still plenty of other packaging materials that can have a negative impact on the environment if not responsibly conserved. Two of the most recyclable and reusable — and often overlooked — materials are glass and aluminum.

Greener Goals

In 2018, 39.6% of beer and soft-drink bottles were recovered for recycling, according to the U.S. Environmental Protection Agency, with 39.8% of wine and liquor bottles and 15.0% of food and other glass jars recycled. In total, 33.1% of all glass food and beverage containers were recycled. Meanwhile, according to the Washington, D.C.-based Can Manufacturers Institute, the aluminum beverage can recycling rate was 45% in 2020.

Bumping up these percentages can vastly improve retailers’ sustainability goals. In fact, glass is infinitely recyclable — unlike some plastics — without experiencing any loss in purity or quality. The Arlington, Va.-based Glass Packaging Institute points out that more than a ton of natural resources is saved for every ton of glass recycled. One ton of carbon dioxide is reduced for every 6 tons of recycled container glass used in the manufacturing process.

The Can Manufacturers Institute also estimates that increasing the recycled content of the average can reduces its carbon footprint, since making an aluminum beverage can from recycled material results in more than 90% fewer greenhouse-gas emissions than making the container from primary material.

Consumer Collection

Seven in 10 supermarket shoppers are trying to reduce their impact on the environment, as indicated by a recent Coca-Cola Retailing Research Council North America report. Additionally, not all communities have recycling collections come to their homes. As a result, incorporating a recycling collection site at the retail level can have a direct impact on shopper loyalty. A convenient and easy option for grocery stores to help shoppers recycle aluminum and glass is via reverse vending machines, which collect empty and used bottles and cans in return for money or other forms of incentivization to the recycler.

One example of reverse vending solutions for collecting, reusing and recycling aluminum and glass is Norway-based Tomra. With 82,000-plus installations across more than 60 markets, Tomra’s reverse vending machines capture 40 billion used beverage containers every year, reducing reliance on raw materials and ensuring that fewer containers end up in landfills, oceans and streets, while bringing real benefits to stores and their communities.

Tomra’s various systems are geared toward grocery retailers of any size, with indoor and outdoor installations available. Units now have the option to issue recycling refunds not only with a traditional paper voucher, but also with a digital voucher — sent directly to the end user’s mobile phone, or via instant and secure electronic transfer to their account. Both digital payouts are enabled through the myTOMRA app. Campbell, Calif.-based Olyns also provides reverse vending solutions. In November 2021, the company raised a $1 million seed round led by Vanedge Capital. Olyns’ eye-catching bottle collection machine is designed for high-traffic indoor locations, and its gamified mobile app provides bottle refunds and rewards. Each Olyns machine reportedly collects about 1.5 metric tons of recycled material per year. Don’t forget partnering with CPG packaging companies like Westminster, Colo.-based Ball Corp., which supplies innovative, sustainable aluminum packaging solutions for beverage, personal care and household products. Driving category growth, the company’s Ball Aluminum Cup can be easily recycled like its aluminum can counterparts. In fact, according to Ball Corp., aluminum cans, cups and bottles can be recycled and back on a store shelf within 60 days. Meanwhile, big-name retailers like Bentonville, Ark.-based Walmart are touting their own recycling efforts. The food retailer joined forces with soft-drink giant PepsiCo Beverages North America in late August 2021 on a pilot program to boost recycling awareness and participation in Tulsa, Okla. Shoppers were invited to bring their beverage containers to be properly recycled from Thursdays to Sundays, with encouragement to participate via the chance to earn rewards and prizes.
