The U.S is the leading country for producing waste in landfills.  292.4 million tons to be exact.  The top 3 waste products in landfills are food, paper/paperboard and plastics which most of those products can be recycled.  You can do your part by recycling paper/paperboard and plastics (even if you don’t get paid for them), and as an example for food, starting a compost bin with food scraps.
