This easy and convenient procedure helps those with aluminum foil or Ziploc bag lunches reuse their resources. Many people don't know that aluminum foil that is soiled or has traces of food cannot be recycled. In addition, Ziploc bags cannot be recycled in ordinary recycled bins (you have to bring the bag to a plastic bag recycling center). Instead, aluminum foil and plastic Ziploc bags can be washed, then reused! This way, you can save money and help save the Earth and its limited resources.
