Circular scenario models for insight into the circular value chain of materials
The Netherlands, like the rest of Europe, aims to achieve a 100% circular economy by 2050. This is a significant challenge, as the entire system must be adapted alongside the energy transition. To understand what is required for this circular transition, TNO is developing circular models. These models provide governments and businesses with independent insights into circular strategies and the system impact of the value chain.
Future scenarios for technology and policy
Through these models, we map out future scenarios for technology and policy. Our focus is on the broad value chain of materials, as well as specific materials such as the plastics value chain.
By gathering and processing large volumes of data, knowledge, and expertise – exclusively available within TNO – we can analyse system scenarios. This enables governments and large industries to make informed decisions about the transition to a circular economy.
We have developed two circular models for this purpose:
TNO's PRISM model for insight into the plastics value chain
In addition to the CITS model, TNO has developed a specialised model that focuses on plastics recycling, known as the Plastic Recycling Impact Scenario Model (PRISM). This model incorporates knowledge of all currently known recycling technologies, including innovative methods such as thermochemical recycling or dissolution. PRISM assists organisations in developing strategies for efficient and circular plastic design and recycling. We achieve this by modelling and optimising current and future plastic recycling routes.
The figure shows a flow chart (a Sankey diagram) that represents how plastics can "flow" through our society in a circular economy in 2050, from raw material to end of life. Each color of the flow reflects a different process, and the thickness of the flow equals the size of the stream. The flow chart starts with raw material, which is either fossil (such as oil), recyclate (already recycled plastic) or bio-based (from agricultural products). The next column presents the type of polymers made from this. The third column shows the different product groups made from these polymers, such as packaging or electronics. Column four shows the flow of different methods of plastic waste collection and what the optimal recycling option is in 2050. Column five then shows how much new raw material we can produce from plastics by applying recycling.
