For our office/site in Zwijndrecht we are looking for a

Process Engineer Circular Solutions (F/M)


The Process Engineer Circular Solutions role is to support the Global Technology Manager Circular Solutions, the business and different sites globally on projects on circularity of plastics (chemical or mechanical recycling). This includes exploring new technology options, participating in defining the outline of projects and ensuring the design packages for the projects that are technically sound and where technology risks are identified and mitigated.

INEOS Styrolution is exploring new ways to increase the circularity of plastics and we have projects to build recycling facilities, either in-house or via strategic partnerships. Focus is on mechanical and chemical recycling: to convert collected post-consumer polystyrene waste into new PS/ ABS products or into styrene monomer.

The jobholder in this role will actively be present during the operation and perform critical data analysis of this pilot plant on chemical recycling of PS. This will allow the jobholder to identify eventual improvements of this existing asset.

For future projects, both in mechanical and chemical recycling, the jobholder will assist in reviewing and advising on technology options and critical equipment suppliers. He/she will be actively present when performing tests with technology partners and equipment suppliers.

We work on key projects in both EMEA and NAM with industry partners and research and technology institutes and will start projects in APAC as well. Key activity of the Process Engineer Circular Solutions is to overlook the pilot plant runs with the technology provider on polystyrene depolymerisation and perform a critical data analysis of the results obtained. Key objective is proof of concept and proof the reliability of the design that is than basis for a scale up to a commercial unit. Different feedstocks and process conditions will be tested. Work with technology provider and maintenance team and if/ when necessary optimize the design to reach reliability target. After proof of concept further pilot plant work is planned to optimise process and yields (e.g. recycling of oligomers and possible catalysts).

In addition, the Process Engineer Circular Solutions will screen regularly for any new technology on styrenics recycling, new equipment suppliers active on circularity or advances in technology for plastic waste sorting and purification that is supportive for the shift to a circular economy.

Collaboration inside company, within INEOS and with selected partners is critical for the success of the projects. Team work is required with the technology and equipment providers and Global R&D. As the capital projects are organized in site/ regional teams, the job also requires working with site process and project teams.
