MoistureShield composite decking is made from 90% recycled materials, including pre-consumer kiln-dried oak mill waste, waste pallets, and construction debris. The plastics in the product include low- and high-density polyethylene from recycled milk jugs, grocery bags, detergent bottles, pallet wrap, and food packaging waste. Sixty percent of the materials that go into its deck boards and deck tiles is post-consumer, which is about two and a half times the requirement for LEED for Homes, the manufacturer claims.
