Valencia/Reutlingen, July 22, 2020 – A consortium of European industrial and scientific partners, including iPoint, is collaborating to convert waste plastics into valuable chemicals in cost-efficient and environmentally-compatible way, by integrating advanced catalytic processes, artificial intelligence, Life Cycle Analysis, and economic analysis.
Approximately 70% of European plastic waste (18.5 Mt/year) is not being recycled due to technical or economic reasons and is thus sent to landfill (27%) or incinerated (42%). This situation affects the environment negatively in terms of pollution and greenhouse gases emissions, as well as social perception regarding waste management, consumer’s products industry and policy makers.
The "Integrated catalytic recycling of plastic residues into added-value chemicals (iCAREPLAST)" project is set to address the cost and energy-efficient recycling of a large fraction of today’s non-recyclable plastics and composites from urban waste. The iCAREPLAST project has received funding by the European Union’s Horizon 2020 Research and Innovation programme within the SPIRE (Sustainable Process Industry through Resource and Energy Efficiency) initiative.
In this research project, heterogeneous plastic mixtures will be converted into valuable chemicals (alkylaromatic) via chemical routes comprising sequential catalytic and separation steps. This multistage process will also yield carbon char and a pure captured CO2 stream as products, whilst it will present improved economic sustainability, operational flexibility and lower CO2 footprint thanks to:
demonstrating that the whole technology for plastic waste valorisation in a pilot plant is able to process >100 kg/h of plastic.
the energetic valorisation of gas by-products through innovative oxycombustion units integrated with efficient heat recovery,
the use of AI predictive control and real time optimisation of sustainability parameters.
The iCAREPLAST solution will enforce the circular economy by substantially increasing the amount of recycled plastics to produce commodity products that can be used for virgin-quality polymers production or as raw materials for other processes in petrochemicals, fine chemicals, as well as automotive and detergent/surfactants industries. As a result of its initial exploitation the project will treat 250,000 t of plastic waste which otherwise would have become landfill, converting it into 1,500 t of alkylaromatics and 1,000 t of aromatics. Additionally, liquid and gaseous streams of rich-hydrocarbons (including CO2), and solid sub-products (char) will be also recovered and valorised to maximise material and energy balance of the overall process, thus minimising environmental footprint and ensuring economic sustainability.
iCAREPLAST: The key to closing the plastic recycling loop
iCAREPLAST combines pyrolysis, catalytic upgrading and conversions, membrane separation technologies and oxy-fuel combustion systems to obtain high added-value chemical in an energy- efficient and environment-friendly context. To generate products with a minimum environmental impact, AI-based advanced control systems will be applied at the pilot plant. Thereby, indicators based on LCA (life cycle assessment) and LCC (life cycle cost) analyses are integrated.
