The Benefits of Recycling Aluminum Foil
It turns out that aluminum foil can be used for more than preserving leftovers. According to a university researcher, dirty aluminum foil can be converted into a catalyst for biofuel production. Scientists were able to dissolve the foil in a solution that turned it into crystals. A second mixture was used to purify the crystals into pure aluminum salts, which can be used to create an alumina catalyst.
