Sidel opens new hub to develop design for recycling primary packaging

Sidel has opened a new hub dedicated to PET recycling. At its unique small-scale PET recycling pilot line in Octeville, France, Sidel will develop its understanding of PET recycling to give comprehensive support to the market as it switches to greater use of recycled PET.

Seeking carbon neutrality, the packaging industry is in the middle of a transition period that aims to replace virgin PET with recycled PET. Sidel is engaging with this transition to circular packaging solutions, enabling r-PET to be more widely used. The unique small-scale PET recycling line will allow Sidel to develop advanced knowledge about recycling food-contact PET bottles. As Sidel packaging experts assess the impact of additives and primary packaging materials on r-PET resin the facility will become an important reference for raw material producers, recyclers, and recycling regulatory organizations. The line will also enable Sidel further develop its knowledge, ideas, and innovative packaging solutions. 

Helping to meet the demand for r-PET

Demand for r-PET is increasing, and the market is developing as brand owners seek carbon-neutral solutions. The amount of recycled PET in packaging globally has increased to 8% compared to 5% in 2018. In Europe, the average is already 15% and is projected to grow to 35% in 2030.

“There is a big move towards recycled PET, but demand is outstripping supply,” says Naima Boutroy, global packaging expert, Sidel. “The market still has a lot to learn and we can provide valuable insights. There is variability in recycled PET resin grades, and standardization is still in development. We need to address this to create the best possible finished bottles. Our line will test the recyclability of post-consumer PET bottles from different feedstocks, including additives and caps as well as labels, inks, and glue. We will be working with traditional Sidel customers such as brand owners, converters, and co-packers, as well as other suppliers like raw material producers, recyclers, and regulatory organizations, to enable the scaling-up of r-PET capacity. We can also check if any innovations comply with bottle-to-bottle recycling.” 

The fully-equipped line to study the entire process

Sidel’s new line will take raw materials from industry partners such as sorting facilities, recyclers, and brand owners. It will then recreate and study all aspects of the process from bales to flakes including pellets ready to be injected into preform, injection, and blow molding.  

Sidel will allow the packaging industry to access a fully equipped pilot line. This line covers every step of the recycling process: from washing, drying, and pellet extrusion, to solid-state polymerization, including dedicated process and laboratory controls at every step.

Making PET a more sustainable choice

PET is proven to be recyclable and is the only food-safe bottle-to-bottle recycled material, but the market has yet to see the production of standardized r-PET resin grade in high quantities; achieving this could facilitate the market conversion from virgin PET to r-PET. Lifecycle analysis shows that PET already has the best carbon footprint among materials currently available; creating a robust recycling loop to achieve full circularity at scale will make PET an even more sustainable choice. 

Sidel to become a one-stop shop for r-PET

Sidel’s investment in the r-PET pilot line is unparalleled in the packaging industry and will also empower Sidel to shape future packaging solutions. The line, which has a holistic bottle-to-bottle approach, is just one of a range of services that Sidel is establishing under the name RePETable™ services. The services will draw upon Sidel’s 40+ years of blowing and packaging expertise, to support brand owners and converters in producing r-PET bottles through line upgrade solutions, packaging optimization, blowing process qualification, troubleshooting, and r-PET processing training.
