Russellville, Arkansas — Grocery stores that switched from separating unsold food by hand to machine depackaging increased the amount of food diverted from landfill to recycling by an average of 70 per cent, according to new figures from Denali, the United States’ largest recycler of food and organics.
The finding, published in Denali’s 2025 Sustainability Report and based on data from more than 3,300 US stores, shows how a practical technology change can keep large volumes of food waste out of landfill — where rotting organics release methane, a potent greenhouse gas.
Machines do what hands cannot
Denali’s depackaging programme mechanically separates unsellable food from its packaging, replacing manual food separation. According to the company, the switch reduces the need for manual labour and makes food diversion more practical at scale, because packaged food that cannot be sold — from grocery shelves, delis and distribution — can be processed quickly and consistently.
Food recycling complements food waste prevention and donation efforts, Denali notes. It creates renewable products from food that can no longer be consumed, rather than letting it go to landfill.
The scale of the operation
Across its operations, Denali managed 14.8 billion pounds of organic materials in 2025, including 1.35 billion pounds of uneaten food. The company pairs commercial food and organics collection with recycling services for grocers, restaurants, food manufacturers and processors, municipalities, convention centres and other food-related businesses.
Its work also covers nutrient recovery, resilient agriculture and biodiesel production, turning recovered organics into productive use.
“Businesses need a practical and cost-effective way to keep unused food out of landfills and know with confidence what happens after it’s collected,” said Denali CEO Todd Mathes. “Our nationwide direct service capabilities, owned recycling operations and diverse partner network maximize landfill diversion and deliver value to our customers.”
Why diverted food matters
When food ends up in landfill, it decomposes and releases methane, which is more than 80 times as powerful as carbon dioxide over 20 years. Diverting food to recycling avoids those emissions and returns the material to productive use — as compost, animal feed inputs, energy or other renewable products.
The result also points to a wider lesson for waste systems: measurement and technology matter. Denali says its data helps customers track their progress and improve inventory management, so less food becomes waste in the first place.
