We want to switch to reusable totes for B2B shipments, but our third-party warehouse flagged California food-contact sanitation rules as a blocker; has anyone documented a compliant cleaning protocol that passes an audit and still pencils out on water/energy use? For context, we’re moving about 3,[redacted]/week and evaluated a closed-loop wash at 60°C with peracetic acid, but I’m wary of the LCA tipping if rinse volumes exceed about 8 L per tote…
I’ve had success using a closed-loop system at 65°C with hydrogen peroxide; it cuts down on water usage and meets most sanitation standards. Have you considered adjusting the temperature or the cleaning agent? It might help with compliance.
Have you looked into using ozone sanitation in your cleaning process? It’s effective and can reduce chemical residues, which may help streamline your audits. Just a thought, but I found it works great in similar setups.
