Whole Foods Co-op and Resource Renew Celebrate Compost Partnership
Compost is a nutrient-rich addition to any garden. Previously known as Garden Green, Premium Compost is a special compost created from local food scraps and yard waste and is processed right here in Duluth at Resource Renew, the brand of the Western Lake Superior Sanitary District. Premium Compost is available seasonally at both Whole Foods Co-op stores.
Given the popularity of Premium Compost and our Owners’ love for composting, in April 2025, the Denfeld store became a Food Scrap Drop Site for Resource Renew’s composting program, making it easier than ever for Co-op shoppers to practice composting.
“Shoppers have been asking for us to be a Food Scrap Drop Off Site,” said Erika Osterman, Store Manager of our Denfeld location. “We’re thrilled to be able to provide this service and to help make it easier for our neighbors to keep food scraps out of the landfill.”


Whole Foods Co-op is excited to build on its partnership with Resource Renew, whose composting program keeps over 2,500 tons of organic matter out of landfills every year.
When asked why composting is so important, Dori Decker, Environmental Program Coordinator at Resource Renew shared, “Twenty percent of the trash in our district that is going to the landfill is food waste. Diverting food scraps from the landfill can preserve the longevity of our region’s landfill, which is projected to close in 2026, reduce greenhouse gas emissions, and reduce household trash volume (which can mean savings for the household!).”
The Food Scraps Drop Site bin is open 24/7 for people to deposit their food scraps. At-home food scraps buckets and BPI-certified compostable bags are available for free through Resource Renew, and additional bags are available for sale at both Co-op stores. Resource Renew encourages the use of BPI-certified bags to keep the drop sites clean and reduce critters and bugs.

This partnership between Whole Foods Co-op and Resource Renew closes the loop, turning food scraps into valuable compost while supporting the environment. Owners, shoppers, and community members are invited to use the Food Scrap Drop Off Site in their composting routine and are encouraged to complete the loop by looking for Resource Renew Premium Compost at Whole Foods Co-op every spring to nurture their gardens.

Resource Renew Premium Compost and BioBag BPI Certified Food Scrap Bags are available seasonally at both Whole Foods Co-op stores!
The Composting Process
Just how does a banana peel and coffee grounds become compost, a nutrient-rich soil? They follow a 9-month journey at Resource Renew’s facility.
Steps:
- Material Collection: Residents and businesses drop off organic materials at designated sites, including the Whole Foods Co-op Denfeld store. Drop site accepted materials include food scraps and BPI-certified compostable products, which are free of plastic, metals, and other non-compostable items. Please note that yard waste is to only be dropped off at the Yard Waste Compost Site.
- Sorting: Collected materials are transported to the composting facility, where they are meticulously sorted to remove contaminants.
- Grinding: Larger organic materials are ground into smaller pieces to accelerate decomposition.
- Mixing and Aeration: Ground materials are combined with the daily delivery of food scraps to create a uniform mix of carbon-rich and nitrogen-rich materials. Aeration promotes microbial activity, essential for effective decomposition.
- Active Composting: Compost is placed in large, aerated windrows, or piles, for several weeks, with staff monitoring temperature, moisture, and oxygen levels. High temperatures help eliminate pathogens and weed seeds. Compost can reach temperatures exceeding 150 degrees.
- Turning and Monitoring: The compost pile is periodically turned to maintain optimal conditions for microbial activity.
- Curing: After active composting, the material cures for several months, allowing it to mature and stabilize its nutrients.
- Screening and Packaging: Mature compost is screened to remove oversized particles and contaminants, then packaged for distribution.
- Community Distribution: Premium Compost is available for purchase throughout the area, including at both Whole Foods Co-op stores.
