POST-INDUSTRIAL RECYCLING | TECHNOLOGY
post-industrial recycled grade) comes into its own when used to replace metal in railings due to its high mechanical and UV stability performance. Eurotec offers a range of Tecoleneco solutions
aimed at automotive under-hood parts such as brackets and clips as glass fibre reinforced homopolymer PP grades containing PIR packaging waste. These solutions display similar mechanical properties to virgin materials and customised MFI values in line with the part design. For instance, Tecoleneco HP22 GR20 NL HS/M50I (PPHP, 20% glass fibre reinforced, heat stabilised, natural, post-industrial recycled) meets the requirements for OEM specifications due to its accurate heat stabilisation and formulation as well as having the ability to maintain mechanical properties after 2,000 hours of thermal aging at 120° C.
All on film Film production waste is often recycled by flexible packaging producers, but it is not necessarily a straightforward process to reuse film scraps. Recycling machinery companies have been further developing technology that helps film converters improve and use more in-house waste feedstock.
Austrian recycling machine manufacturer Erema has a long association with flexible packaging producer Polykar, which began recycling post- industrial and post-commercial PE film with the purchase of an Erema T recycling system back in 2008. In 2014 the company became one of the first to adopt an Intarema TVEplus recycling system with SW RTF melt filter that featured patented Counter Current technology, which Erema had recently developed. In December 2022, Polykar opened a new 15,240m² plant in Edmonton, Alberta, in Canada, housing an Intarema 1310 TVEplus machine with backflush filter which recycles heavily printed LDPE production and industrial waste from blown film production and has a capacity of 3,600 tonnes/yr.
Among many other projects, Erema has worked with Spanish recycling company Anviplas to improve recycling processes for complex multilayer materials. Anviplas uses an Intarema 1716 TVEplus with screen changer to recycle PIR and PCR HDPE and LDPE, as well as PP, into pellets. Further processing of films into packaging products generates heavily printed waste which is often laminated or metallised presenting huge challeng-
