Recycling Girl explained that soda cans and plastic bottles can be recycled, as well as construction paper and old tests, but not paper towels or food wrappers. Recycling one soda can saves enough energy to watch a couple hours of TV. Items that cannot be recycled include wood, liquids, living things, food, and fabrics. Each year, 175 million tons of trash ends up in landfills, so continuing recycling efforts is important.
