Furniture made from recycled plastics is gaining prominence in the outdoor furniture industry. Recent advancements in manufacturing the material have made it a feasible alternative to what is traditionally used.
High density polyethylene or HDPE is a material derived from the number 2 type of recycled plastic. The most common container is the gallon milk jug. They are those semi-white jugs that you can see through a little. They are not the material used for solid white containers or the clear 2-liter bottles.
One form of HDPE that has come onto the market is called Polywood. It essentially is plastic lumber produced from type 2 waste recovered from recycling centers. Polywood is actually heavier and stronger than lumber cut from wood. First, the recycled plastic is crushed into pellets and then melted in a pot. Next, ultra-violet substances and color are added. This gives HDPE a huge advantage over traditional wood lumber. The liquid is then cured in molds shaped to normal sizes of lumber. The final product has a grain finish instead of having a smooth polished feel. I expect this material will soon be sold side by side with wood lumber in the home improvement chain stores.
