Most of these projects involve reusing these nifty envelopes by means of sewing, cutting and using the provided adhesive to create new and useful things. Since these envelopes cannot be recycled easily why not transform them into something else instead of chucking them into the thrash.

If you want to recycle your leftovers, DuPont has started a Tyvek Recycling program since regular curbside pickups do not accept this type of plastic.

“For Small Quantities (less than 25 envelopes/month)
Turn any Tyvek® envelope inside out, so the unprinted white surface shows on the outside. Stuff the inside-out Tyvek® envelope with other used Tyvek® envelopes for recycling.

Address and mail the envelope to:
Tyvek® Recycle
Attn. Shirley B. Wright
2400 Elliham Avenue #A
Richmond, VA 23237

For Medium Quantities (more than 25 but less than 500 envelopes/month)
Call 1-866-33-Tyvek® and ask about our pouch program for recycling Tyvek® envelopes. Each pouch holds approximately 200 used Tyvek® envelopes. Collect your envelopes in the pouch and then forward them to DuPont – address label provided.

For Larger Quantities (more than 500 envelopes/month)
Contact Shirley B. Wright, Tyvek® Recycling Specialist, at 1-800-222-5676 or 1-866-33-TYVEK® for information”
