POST-INDUSTRIAL RECYCLING | TECHNOLOGY
Getting more from in-house recycling
By recycling process waste, plastics manufacturers can reap business benefits and contribute to the circular economy agenda. David Eldridge reports on new developments and technology
Post-consumer recycling takes the leading role in efforts to align the plastics industry with circular economy objectives. But post-industrial recycling is a longer established activity and is one which continues to grow, as plastics processors strive for resource efficiency by converting production waste into feedstock. Packaging film extruders are ramping up the amount of process scrap they reuse and converters are increasingly seeking closed loop solutions for post-production waste such as heavily printed stock. Film extrusion and packaging conversion are key areas targeted by recycling technology suppliers, although other process areas and market sectors are emerging that require post-industrial recycling options.

“Everyone is talking about the circular economy, and not only in terms of post-consumer recycling,” says Andreas Dirnberger, Business Development Manager Application Inhouse and Industrial, at Erema Group. “Manufacturers and processors of plastic products such as packaging films are also pursuing a zero waste strategy. By recycling production waste, costs can be saved, and the use of energy and the number of transport journeys can be reduced, which in turn helps to protect the climate.”
Each type of in-house waste presents its own challenges. A typical application is the recycling of clean, unprinted film waste, such as edge trim. But processors must also deal with other waste types.
