"After the Hefty EnergyBag orange bags have been picked up by one of the participating haulers (American Disposal, B Green Services, Custom Disposal Service and Pickers Waste Service), they are sent to WestRock where they're sorted, baled and sent to an approved end market," explains Nelson. The approved destinations include Nexus, as well as qualification trials at developing end markets. "Once the Hefty EnergyBag orange bags are separated at WestRock, we receive the hard-to-recycle plastics, converting them into feedstocks for plastics production through thermal depolymerization (pyrolysis)," adds Gold. Decontaminated recycling streams Nexus uses the pyrolysis liquid produced from the collected plastics to create new, food-grade quality plastic. "We can break the plastic down to its molecular form.
