Earth Day 2024: Why Recycled Aluminum Medals Are Having a Moment 🌍

Recycled-content aluminum cuts the carbon footprint of a finisher medal by about 90% versus virgin metal — and looks identical in the hand. Race directors are switching fast.

Why the Carbon Number Is So Big

Smelting virgin aluminum from bauxite takes roughly 14 kWh per kilogram. Re-melting recycled scrap takes about 0.7 kWh. For a 50g medal at a 5,000-runner race, that gap translates to about 3 tons of CO2 avoided per event — a number worth printing on the back of the medal itself.

Finish Quality Is Indistinguishable

Recycled aluminum takes anodizing identically — same color depth, same wear resistance. The visible difference under a microscope is zero. The only real trade-off is supply volatility; lock your quantity in early so the foundry can source matched-grade scrap for your full run.
