Size reduction is a crucial step for reprocessing post-industrial plastic waste and suppliers have launched improved technology for this purpose. Genox, a manufacturer of waste recycling machin- ery and equipment based in China, developed its new GCV shredder-granulator series as a simpler, space-saving, and energy efficient alternative to
plastic processing methods that incorporate a standalone shredder and standalone granulator. “When it comes to reducing plastic waste, tradi- tional shredder and granulator lines are a well- established solution, however investing in these systems can be costly and they take up consider- able space, which can be a challenge to processors with limited resources,” says Genox. The company’s GCV series dual-purpose machine integrates the shredder and granulator into an all-in-one unit, eliminating the need for conveying equipment, which reduces the floor

Although the use of post-industrial waste for engineering plastics solutions is not new, it has become increasingly important with the introduction of sustainable product goals in recent years. Products with post-industrial waste content has the potential to be used in many func- tional applications by achieving sustained raw material quality and maintaining material performance in the long term under demanding test conditions, as well as the advantage of providing a low carbon footprint as a sustainable product, says engineering plastics compounder Eurotec. The recycling of post-industrial wastes has advantages including lower contamination content, more sustainable quality and less thermal and weathering degradation com-
pared to post-consumer materials. Eurotec developed partly or 100% recycled formulations using post- industrial waste solutions from numerous industries, from automotive to white goods, electrical and electronics to daily life applications. The group’s Tecomid line is comprised of formulations made from recycled PA compounds produced from textile fibre waste. Creating the tailored formulations from the PA-based industrial waste requires the elimination of metal and other contaminants, then converting the fibre into granules on the extrusion line, followed by drying the recycled granules and metal separation. Eurotec offers, for example,
Tecomid Eco NA43 GR30 BK005 HS, a grade with post-industrial recycled
PA6.6 that is 30% glass fibre rein- forced, black, and heat stabilised. It is suited to automotive applications such as pedal guards, cooling fan guards, air intake manifolds, oil pans and engine cover, where it displays good thermal, chemical and long- term mechanical properties. Its Tecomid Eco NB43 GR30 BK009/ M65I formulation, containing 65% post-industrial PA6, along with 30% glass fibre reinforcement in black, is a metal replacement solution in railings where it provides a safe working environment due to its high mechani- cal and UV stability performance. Eurotec also offers its Tecolen range

of glass fibre reinforced homopolymer PP grade materials containing post-industrial packaging waste. These materials display mechanical proper- ties similar to virgin materials and can be made with customised MFI values in line with part design. The Tecolen grades are aimed at automotive under-the-hood parts, such as brackets or clips. One such grade Eurotec offers is Tecolen Eco HP22 GR20 NL HS/M50I, a post industrial recycled PPHP that contains 20% glass fibre reinforcement, is heat stabilised and natural in colour. Eurotec makes sustainable grades that allow for a wider range of use and display better performance to meet demanding technical requirements.
