Since plastic products can also be made from materials with complex structures, it is necessary to develop different complementary recycling technologies — such as mechanical and chemical recycling — in order to recover all types of waste, even the most heterogeneous.

The Versalis SC-HOOP Project indicates the realisation of the chemical recycling demo plant inaugurated in Mantua in June 2025. The plant is based on Versalis’ proprietary pyrolysis technology named Hoop® and is designed to valorise the plastic waste that is not currently recycled.

The Hoop® process will turn secondary material derived from recycled mixed plastic waste (feedstock) into a recycled naphtha (r-naphtha). This latter can subsequently be used to replace or be added as an alternative feedstock to produce new intermediates as well as polymers suitable for all applications, with benefits in terms of sustainability, yield, higher feedstock flexibility and quality.

The Mantova pilot plant will produce almost 5000 tonnes per year of r-naphtha (also referred to as pyrolysis oil), converting 6000 tons per year of secondary raw material from mixed plastic waste,  with absolute greenhouse gas emissions avoidance of 139.838 tonnes of CO₂ equivalent over the first ten years of operation compared to equivalent virgin naphtha production from oil refinery and with a relative greenhouse gas emissions avoidance of 81% compared to the reference scenario. The entire process is designed to provide greater benefits from both an economic and environmental viewpoint.

The SC-HOOP Project supports the implementation and development of circular economy. In particular, it is strategic for us to achieve the challenging EU recycling targets and full circularity of plastics. Moreover, it is the only Italian “large scale” initiative that has been awarded, out of 41 total winners, the 2023 ‘EU Innovation Fund’, allocated by the European Commission and focused on innovative low-carbon technologies.
