The tubes are made of: PP ( # 5) and the tube is Co- Ex EVOH/ PE so it would be a #7 Other and the bottle is made of: HDPE and a #2 and the cap is PP a #5. It depends on where you live if these materials are recyclable but PP is almost always! It's a good idea to pour some water into the container, put the cap on tightly, and then shake the container to help remove any leftover bleach. Pour out the water before putting the cap back on a final time. Dispose of the container in the trash if you can't recycle it.
