CP AXTRA, Thailand's major retailer, is implementing a "Zero Waste to Landfill" strategy across its Makro and Lotus operations (serving ~40M shoppers), addressing the fact that 96% of retail sector emissions come from Scope 3 (upstream supply chain). The company is reducing waste prevention through three pillars—Measure, Prevent, and Divert—using tools like breathable packaging for fresh produce, vacuum sealing, demand forecasting systems, and food-surplus redistribution programs ("Eat Don't Waste") to communities. Surplus food and recyclable materials (cardboard, plastic wrap) are redirected to secondary uses (animal feed, protein cultivation, energy production) rather than landfills, creating both environmental and economic value for suppliers and local communities.
