Renewable and recyclable?Recycling Today

 · The process uses mechanical force to separate face fiber, backing fiber and calcium carbonate from backing material. No washing, chemicals or high heat are needed. The separated carpet fibers are used as feedstock for chemical recycling to produce virgin-like resin. The fiber also can be pelletized or densified and used in injection molding.

PET Fiber Carpet

Due to the high intrinsic viscosityrequirements of the bottle industry, bottle-grade PET resin is superior tovirgin carpet-grade resin in terms of strength. This characteristic is retainedthrough the recycling process due to the fact PET is a thermoplastic materialwhich can be melted and reformed with virtually no change in physicalproperties.

New Approach for Breaking Plastics Down Shows Promise

 · Most recycled plastic is mechanically ground up and “downcycled” into lower quality, nonrecyclable products like carpet fiber or polyester thread. Pyrolysis, however, can break the plastic down into chemical “feedstocks,” which could then be recycled (upcycled) into fuel or even used to create new virgin plastic, a process that could be .

New Developments in Recycling Fiber and Carpet Waste

Carpet/fiber and trims are chopped into small pieces using a single shaft shredder. Shredder Step 2. Grinder Separator Air or liquid The smaller screen in the grinder provides final particle size of 1/4 to 3/8 inch for separation. reduces to 1 to 3 inch pieces Step 1. Shredder Scrap material Fiber Backing

Recycling glass fiber thermoplastic composites from wind

The material was then injection molded into ASTM type IV dog bones using a Morgan-Press G-55T injection molding machine with a barrel temperature of 245 °C (ASTM D 638, 1941).The ground material initially contained a fiber content that was too high to be effectively injection molded; therefore, a weight equivalent of the polymer precipitated from the dissolution experiment was added to the .

Mechanical vs. Chemical RecyclingBentley Mills

Within the carpet industry, an example of mechanical recycling would be the shearing of post-consumer, nylon, face fiber to be used in needle-punched underlayment or other consumer products. An example of chemical recycling would be nylon depolymerization, where heat is applied to post consumer nylon to deconstruct polymers into their simplest building blocks (monomers). Once […]

Composites recycling is gaining traction | CompositesWorld

First, the European Union’s end-of-life-vehicle (ELV) directive requires that 85%, by weight, of the materials used in a car or light truck must be reusable or recyclable.; Second, carbon fiber’s high manufacturing cost and high performance, even in chopped form, make it an attractive recycling target, which is creating market pull for recycled fiber products, most notably, from automotive.

Composites recycling: Gaining traction | CompositesWorld

Pyrolyzed reclaimed fibers reportedly retain virgin carbon fibers’s key performance levels . A test coupon of PArCF30 thermoplastic composites filled with CarboNXT carbon fibers, reclaimed via pyrolysis is displayed by a CFK Valley Recycling technician. Fiber properties, post-pyrolysis, are said to be virtually unchanged from virgin data.
