PepsiCo aims for 25% recycled plastic content by 2025

AS part of its sustainable plastics vision, PepsiCo has set a new goal to strive to use 25% recycled content in its plastic packaging by 2025. PepsiCo aims to achieve this goal by collaborating with suppliers and partners, helping to increase consumer education, fostering cross-industry and public-private partnerships and advocating for improved recycling infrastructure and regulatory reform. The goal includes an aim specific to PET (polyethylene terephthalate) beverage bottles to achieve 33% recycled PET content by 2025. Already, PepsiCo is one of the world’s largest users of food-grade recycled PET. PepsiCo’s new goal builds on goals announced in 2016 under the company’s Performance with Purpose 2025 Agenda. The 2025 Agenda included goals for PepsiCo to strive to design 100% of its packaging to be recyclable, compostable or biodegradable; to increase its use of recycled materials; to reduce the carbon impact of its packaging and, in partnership with the PepsiCo Foundation, to work to increase recycling rates.

Songwon expands inhouse production in South Korea A NEW production line at Songwon’s site in Suwon, South Korea for the manufacture and distillation of Songsorb® CS 400 UV stabiliser has become operational. With a total capacity of about 1 000 metric tons, it allows fully backward integrated inhouse manufacture of Songsorb CS 400 at all stages from intermediate to finished product. Other individual coatings additives as well as blends of UV absorbers and hindered amine light stabilisers are produced at the site. Songsorb CS 400 is a liquid hydroxyphenyl triazine (HPT) UV absorber designed to ensure high performance and durability in waterand solvent-borne as well as 100% solid automotive and industrial finishes. It has very high thermal stability and outstanding resistance in coatings exposed to high bake cycles and/ or extreme external conditions. It is suitable for use in amine and metal catalysed coatings, substrates containing such catalysts and coatings applied on topcoats. 78

Successful demonstration of new, innovative LSP system

MORE than 117 representatives of the plastics industry from 24 countries met in November for an open day at the Upper Austrian mechanical engineering company Next Generation Recycling Machines (NGR). In cooperation with the German machine supplier and extrusion specialist Kuhne GmbH, an innovative recycling process for polyethylene terephthalate (PET) was demonstrated to the interested audience. Previous methods of recycling PET back to near-virgin quality have shown limitations. The LSP recycling method developed by NGR now opens up completely new possibilities for the plastics industry. Achieving food grade standards, decontamination and rebuilding of the molecular chain structure takes place in the liquid phase of the PET in the LSP process. This principle allows recyclers more flexibility with regard to the input materials. Different forms of PET waste can be mixed and recycled. This means not only bottle flake, but also scrap fibre, sheet, thermoform waste, strapping, and other lower

value scrap streams can be recycled to much higher IV and higher value recycled products. In addition, the NGR process at the outlet provides controlled mechanical properties of the recycled PET. Furthermore, LSP can be used to process co-polymer forms of PET (PET-G) and polyolefin contents (e.g. PE) without any problems. In addition, it had been demonstrated that PET/ PET-G as well as PET/PE compounds can be easily and safely processed using Liquid State Polycondensation without any limitations. Until now, this was not possible with conventional recycling processes. After the melt has passed the LSP reactor, it can either be granulated or – like at the demonstration in Feldkirchen – processed to FDA approved film with outstanding optical and mechanical properties by implementing devices such as a sheet die, a roll stack, cutting devices or a winder. These films are mainly used for thermoforming applications. • Represented in South Africa by Safrique International –
