The board wants a sustainability report. The marketing team wants a "Recycled" badge on the packaging. Your procurement team found a supplier offering 100% GRS-certified recycled LDPE at a 15% discount. It looks like a win for the planet and the P&L. It usually isn't.
Recycled PE has a carbon footprint roughly 70% lower than virgin material. However, every time PE is re-melted, the polymer chains shorten. Short chains mean lower tensile strength. To achieve the same safety factor as a 50-micron virgin bag, you often have to increase the thickness of a recycled bag to 80 microns. You haven't saved the planet; you've just moved the waste from the resin plant to the shipping container.
The Expert Perspective: True sustainability in sourcing means "Reduction through Performance." Using 100% virgin material allows for "down-gauging"—making the bag thinner without losing strength. A 30-micron virgin film can often outperform a 60-micron recycled film. You use half the plastic, pay less for shipping, and eliminate the risk of transit failure.
[Sourcing Security Kit]: To help you compare the true physical performance of your current samples against industrial benchmarks, we have included the Supplier Scoring Framework in our Industrial Sourcing Security Kit. Audit the molecular ROI before you sign the contract.
Don't pay for the "green" badge with cargo claims. Audit the molecular performance first.
