Polypropylene (PP) is a versatile material that offers good value and provides key properties such as strength and preservation, making it particularly useful in packaging for the food and cosmetics sectors. However, securing a supply of recycled PP remains a challenge in Canada.
- A large share of PP is collected in mixed streams through curbside collection programs, which limits the availability of a controlled, food-grade source unless advanced sorting is performed.
- Additionally, recycling PP back into food-grade material presents several technical challenges, notably due to its porosity and the need to achieve a high level of decontamination.
These constraints mean that food-grade recycled PP remains available only in limited quantities and at a higher cost, despite its strong potential and the growing market demand.
