Creating circular food-grade recycled polypropylene from post-consumer packaging

The K SHOW 2022

The K Show is always a time when the latest innovations are showcased and it was very encouraging to see the theme of sustainability on the majority of the stands.

Our attendance at the K Show 2022 this month was another highlight; being a great opportunity to meet many of our participants face to face for the first time. It meant we had the pleasure of extended NEXTLOOPP discussions with a wider circle of team members.

It was especially pleasing to see the NEXTLOOPP project being highlighted on so many stands and the eagerness from many to hear about how the NEXTLOOPP project was progressing. We also had a lot of positive feedback from many we met. This is a result of the ongoing contributions from the NEXTLOOPP team and the support from our participants. Thank you to you all.

The real breakthrough into a sustainable circular economy has been the sorting into food packaging combined with the cleaning and decontamination of Polypropylene packaging to food safety standards. This has to meet the standards compliant with the food safety authorities using Challenge Tests for validation, which is the basis for the PPristine rPP resins.

Making an Impact Across the Globe

Polypropylene (PP)  is the most dominant polymer in the recycling stream. In Europe alone we produce 10 million tons of PP and only 15% of this is being recycled.

“We have the fundamental technologies needed to complete the loop with food-grade recycled polypropylene and we have a huge task ahead. We can’t ignore the imperatives of tackling waste today. There’s no excuse for waiting.”

The roadmap will help keep the project in line with industry targets providing 30% average recycled content across the plastic packaging industry by 2025.

Benefit from a Signature Process

PRISM is a new way of rapidly sorting packaging based on intelligent labels with invisible markers that can be detected and sorted using existing high-speed optical sorting systems used in MRFs with minor modifications. This technology uses commercial labelling and decoration methods which are coded with high performing luminescent compounds to sort targeted streams including food-contact plastics, bioplastics, chemical packaging, automotive plastics, black plastics and different grades of one plastic. It will help brand owners to ensure that packaging reaches the recycling loop and boost UK recycling performance.

Current challenges facing the industry

When it comes to food grade rPP there are processes that meet EFSA and USFDA requirements but do not have EFSA approval. What is key in this area is separation of prior food use materials.

The European Food Safety Authority (EFSA) requires the infeed material to have previously been used with food. This is due to the fact that up until now, the major barrier to increasing recycled content has been recyclers inability to mechanically differentiate between PP bottles that once contained chemical products from those containing food.
