US Supermarkets Are Doing Bulk Food All Wrong

What started as a small group of people taking pictures of waste in their communities and tagging it on Instagram with the hashtag #Litterati, turned into a global effort, and even an app, to map and dispose of trash. Users can upload to the app an image of trash and machine-learning algorithm can tag it location, material, and company who made it. The city of San Francisco asked the makers of the app for help documenting cigarette butts and tobacco products on its streets and ended up winning a legal victory over the tobacco industry to increase the taxes on their products.

Recirclable provides reusable takeout boxes that customers can return to a participating restaurant within two weeks to avoid being charged a fee, which allows restaurants to cut down on disposable containers that harm the environment. So far Recirclable is working with 14 restaurants and has had thousands of customers select the reusable option, but the effort is difficult to scale up because reuse requires more effort on the part of the consumer and there’s not yet sufficient infrastructure to streamline the process.

Green Era's biodigester facility processes food waste in a closed, oxygen-free system that captures methane and converts it into renewable natural gas while producing compost. The system, which launched in spring 2025, accepts packaged food waste from restaurants, food banks, grocery stores, and residential composting services. The facility diverts approximately 85,000 tons of food waste annually from landfills and supplies enough renewable natural gas to Peoples Gas to power up to 3,000 homes.

The bulk food aisle in grocery stories - where dry goods are weighed and put in containers that consumers can bring from home - is getting more attention as tech solutions arise to revamp this shopping experience. From SmartBins to MIWA, solutions typically involve using technology to track weight more efficiently and cleanly while generating data on consumer habits. These solutions help consumers save money, have a higher profit margin for companies, and reduce waste in the process.

The University of Notre Dame installed three Grind2Energy systems, which aims to reduce the amount of food waste from the campus’ dining halls. The systems process the waste and send it to a local dairy farm where they break down the material to produce biogas that is used to generate electrical power for 1,000 homes each day in Plymouth, Indiana. While not everyone at the university has committed to the sustainability efforts, these systems can be scaled to be used on other college campuses.

The town of Athens, Georgia has committed to a 100% renewable energy pledge. Both the local government and local businesses are working towards it by implementing sustainable practices such as solar panels and wastewater pretreatment systems.

Fashion has long been known as a major contributor to climate change, but brands (from fast fashion to luxury houses alike) are taking steps to address their carbon footprint. This article lists several initiatives working on reducing fabric waste, such as FabScrap, a NY organization that collects and resells 6,000 pounds of discarded fabric weekly.

Food waste often ends up in landfills, but the Wasatch Resource Recovery facility in Utah transforms the thrown-out food into renewable energy instead. Companies such as Kroger, Dannon, and Nestle send their food waste to the facility on a daily basis, where it is liquefied, broken down by microbes and eventually converted into natural gas.

In South Korea, a combination of grassroots movements and government campaigns have dramatically reduced the country's food waste by 95% (about 400 metric tons a day). Residents are required to buy special biodegradable bags, which serves as a tax that finances 60% of the city's food processing. It's a pay-as-you-waste tactic that also prompts citizens to find creative ways to recycle and compost, and special weighing machines encourage them to extract the moisture first, saving even more money on collection costs.

In Eskilstuna, Sweden, there is a different kind of shopping mall – one that sells used and upcycled goods. In an effort to combat consumerism and bolster sustainability, the mall, called ReTuna, is nicely curated and organized, making second-hand shopping mainstream. The mall sees 700 people each day, on average, and has sold nearly $3.5 million worth of items.
