Paper or Plastic? Neither... is displayed on the new reusable shopping bags from Wal-Mart. The bags cost $1 a piece and are available near the checkout area at the store. In the US, we throw away an estimated 100 billion plastic bags a year. Wal-Mart's new reusable bags are made from 85% recycled material (recycled polyethylene terephthalate or rPET) and should last long enough to replace 50 traditional plastic bags. When the bags wear out they can be returned to Wal-Mart to be recycled. This is part of a larger initiative Wal-Mart has been taking to become more "Green". Along with the reusable shopping bags, Wal-Mart is offering "Green" consumer products which include CFL light bulbs, organic milk, reduced packaging detergent, and extended life paper products.
