DuPont Tyvek is made of high-density polyethylene (HDPE). It is not paper so do not add it to your curbside blue recycling bin and do not bring it to your recycling center. It can be recycled for use in a variety of new products, including plastic lumber for picnic tables, park benches, construction fencing and also mud flaps but it is unclear whether or not Dupont, which makes the product, has a recycling program for Tyvek.
