Tyvek Envelopes are made of a special rip proof high density polyethylene that can be recycled.  Tyvek is also used in home construction. You can mail the envelopes to Dupont and they will recycle them.  Waste Management also recycles them. Not convenient, but better than nothing.

Tyvek is also used in shoe covers, boot covers, hoods, lab coats, aprons, sleeves and pants, which can be recycled here.

We recently got an REI item shipped to us in a big plastic envelope. It was not Tyvek and lacked a recycling plastic number on it.  We did verify with REI that it is recyclable.
