Reduce, reuse, and recycle is a mantra heard time and time again. Yet, not everyone follows it (remember that they are in that order for a reason: reduce what you consume in the first place, then reuse what you can, and recycle the rest). It can be easy though. When you do buy stuff (remember that you should try not to buy things – reduce) buy recycled because there are a ton of reasons from energy consumption to sending a message. Over at Grist they compiled a compendium of reasons to buy recycled.
Still, I’d encourage you to continue buying the 100-percent recycled stuff if you can — for foil as well as any other product — for so many reasons. Recycled content saves natural resources, so we can mine fewer metals, cut down fewer trees, and tap less petroleum. It uses less energy to produce, sometimes dramatically so; recycled aluminum can be whipped up with 95 percent less power than virgin aluminum. Recycled material slashes pollution and saves water, too. And let’s not forget it prevents our consumer castoffs from languishing away in a landfill.
