About
This project seeks to increase recycling of bottles and carpeting materials by combining both materials into desirable composite materials (such as repairable plastic pallets and acoustic panels) of a combined value significantly greater than each separately. Increasing the value of the recycled materials will motivate collection, recovery and recycle rates.
The project also provides the opportunity and motivation for the recyclers to introduce new technologies for recycling, including and especially that for the secondary material streams such as PET and carpet, making recycled plastic more economically attractive.
