Upcycling: New catalytic process turns plastic bags into adhesives

Only a small percentage of plastic bags and other polyethylene packaging is recycled because only low-value products can be made from this waste. Chemists have created a catalytic process that preserves the desirable properties of polyethylene while adding another attribute – stickiness – that increases the value of the recycled product. The adhesive polyethylene could be used to coat wires and metal implants or bond plastic layers. Even latex paint sticks to it.
