Driving the change to more sustainable packaging from polystyrene to polypropylene
Substituting polystyrene for polypropylene to improve the sorting quality and recycling rates of rigid containers
Consumers are becoming increasingly aware of the damage non-recycled materials do to the environment and want change. Brand owners, retailers and packaging manufacturers need to respond to this challenge by shifting to sustainable packaging solutions.
At Borealis we believe that the most sustainable long-term plastic packaging options are polypropylene (PP), polyethylene (PE) and PET. Removing all other plastic polymers simplifies sorting of those three streams and facilitates the need for massively increased recycle rates. Deselection of other materials (i.e. polystyrene (PS), PVC or PET in non-bottle applications) in packaging is gathering pace due to their very low market share, rate of collection and sorting or bad recyclability. Borealis is committed to support the value chain to transition to more sustainable packaging by proposing PP alternative rigid solutions to our partners in the market.
The effective recycle rate of PP is already higher than most plastic alternatives, once PP is collected and sorted. The very rapid growth of polypropylene recycling across the globe in the coming years will support the realisation of our value chain partners sustainability goals.
Additionally, Borealis’ optimized PP production process has a very favourable environmental footprint for energy use, water use, CO2 emissions and very low process waste compared to competing packaging materials.
Borealis’ PP materials enable companies to develop and produce sustainable high-quality packaging solutions, ideally suited to the needs of their customers. With most of our grades having market leading performance and processability profiles, many top brand owners and retailers worldwide already have experience of our PP in their packaging. With our extensive experience and expertise, we can help deliver a smooth transition without disruption in the areas of product design, production process and supply chain.
