Between one-third and one-half of all food produced for human consumption is wasted globally. In retail specifically, waste costs show up directly in disposal fees, lost inventory value, and the energy used to process materials that should never have needed processing. The retailers making the most progress on waste reduction aren’t treating it as a sustainability initiative: they’re treating it as an operations problem.
These are two very different framings, and the second one produces better results.
The Five-Category Audit
Before any strategy can work, you need to know what you’re actually generating. A waste audit, sorting and weighing all waste streams for one to two weeks by category, is the prerequisite for anything else.
The five primary categories for retail waste: packaging waste from receiving inventory (cardboard, fill material, plastic film), packaging waste from selling products (bags, tissue, boxes), food waste for food retailers, paper and administrative waste, and returned products that can’t be resold.
Each category has a different reduction pathway. Receiving packaging is supplier-driven: you need supplier conversations, not just internal decisions. Selling packaging is design-driven: you can change what you use without any supplier conversation. Food waste is process-driven: inventory management, ordering accuracy, and donation infrastructure. Returns are both product design-driven and policy-driven.
Design Waste Out, Then Manage What’s Left
The hierarchy matters: design waste out first, then manage what remains. A return-and-exchange program reduces some waste, but it can’t substitute for products designed to be repaired, reused, or recycled in the first place.
Nike’s Reuse-A-Shoe program collects used shoes and grinds them into material for running tracks and playground surfaces: circular design that addresses end-of-life rather than redirecting it. H&M’s Clothes the Loop program accepts any brand or condition of clothing for recycling or reuse. These are supplier-level programs that retailers with significant purchasing leverage can require.
Smart inventory management reduces waste by addressing the root cause of overstock and dead inventory. A retailer that uses demand forecasting to buy closer to actual need generates less waste than one that overstocks to hedge against stockouts. The technology to do this (real-time inventory visibility, AI-driven demand forecasting, automated replenishment) exists and is increasingly accessible at small retailer scale.
The retailers who are furthest ahead on waste reduction aren’t running the best recycling programs. They’re buying more accurately, sourcing more responsibly, and designing products that last longer before becoming waste.
The Partnership Layer
No single retailer can solve the packaging waste problem alone: the infrastructure for collection, sorting, and recycling is shared, and its quality determines whether “recyclable” packaging actually gets recycled.
Partnering with sustainable suppliers who use less packaging, use recyclable materials, and take back their own packaging changes more than internal programs can. A supplier who provides your product in returnable transit packaging eliminates a waste stream that you’d otherwise have to manage.
Sustain LA sells bulk liquids in refillable containers: a model where the packaging never becomes waste because it never leaves the supply chain. Zero Market in Denver provides bulk household and personal care goods in the same model. These aren’t just niche approaches: they’re applicable at larger scales as the infrastructure for refill programs matures.
P.S. Before investing in any new waste management equipment or program, do the audit first. Most retailers find that their two or three highest-volume waste streams are different from what they assumed, and the solutions are often simpler than expected.
