According to Euwid, the first deliveries of recycled styrene monomer (SM) have arrived at the INEOS Styrolution site in Antwerp.

According to the information, the material was supplied by Indaver from its new Plastics2Chemicals (P2C) plant in Antwerp. It is said to be the first commercial plant in Europe for the chemical recycling of polystyrene and was inaugurated on 25 September 2025. According to Indaver, the plant uses depolymerisation to break down polystyrene waste into its original components. These are then polymerised back into polystyrene (PS) by partner companies. According to Euwid, Indaver has purchase agreements for the recycled PS with Trinseo and Total Energies in addition to Ineos Styrolution. According to Euwid, Indaver initially intends to focus on recycling pre-treated PS from food packaging such as yoghurt pots and meat trays into pure styrene. The company plans to recycle PS and polyolefins (PO) separately at a later stage. Currently, the P2C plant connected to Indaver's pre-treatment site in Willebroek has a capacity of 26,000 tonnes per year and can be expanded to 65,000 tonnes per year with a second line.
 
With Plastics2Chemicals (P2C), Indaver aims to pioneer the circular economy and chemical recycling. By converting hard-to-recycle plastics into raw materials for the production of styrene, the cycle is to be closed and a sustainable alternative to fossil resources offered, according to a statement from Indaver. Depolymerisation is also more energy-efficient than other chemical recycling methods such as pyrolysis, is said. The material would be kept in the cycle and transformed waste back into a valuable resource.
