In order to reduce waste at our manufacturing sites, DuPont has established an onsite recycling facility alongside our Tyvek® manufacturing lines in Luxembourg. The facility uses a sophisticated shredder-feeder-extruder combination system that can process all types of Tyvek® production scrap and turn it into pellets for reuse. This investment in mechanical recycling makes it easy and efficient to re-process post-industrial waste back into high-density polyethylene (HDPE) granulates for reuse.
To provide tangible circular benefits, the recycled granulates are then used to produce plastic cores around which Tyvek® can be wound for storage and shipping. We are working closely with packaging supplier Sonoco to create these winding cores. They are currently extruded in Sonoco’s facility in Germany and then returned to our manufacturing plant in Luxembourg. We then wind sheets of newly produced Tyvek® around cores produced from 100% recycled Tyvek®, whose quality is controlled through our quality management system. Additional benefits of these cores include low particle emission, strength and dimensional stability.
Tyvek® is a lightweight, protective material used in numerous applications. It’s unique properties help ensure medical device packages remain sterile, provide personal protection equipment for people in hazardous or sterile environments, and protect homes from rain and other weather effects during construction.
Combining our experience and unique assets, 2LM and Innofibre aim to expand the established recycling programs currently available for Tyvek® and develop a new and sustainable offering.
In 2018, our Electronics & Industrial Interconnect Solutions site in Sasakami, Japan, began a two-year project to reduce effluents and solid waste associated with the production of chemicals for metallization processes.
