Piezo-photonic High-entropy Oxides ENabling Integrated eXtraction to Polysters (PHOENIX)

Project description

Converting leftover cereal straw into eco-friendly plastics

Europe leaves millions of tonnes of cereal straw underutilised or burned each year, causing resource waste and carbon emissions. However, this agricultural waste could help meet the growing demand for green textiles and sustainable packaging. Supported by the Marie Skłodowska-Curie Actions programme, the PHOENIX project will develop an eco-friendly route to convert cereal straw into valuable bio-polyesters. Researchers will use a solar- and mechanically driven chemical process to transform straw-derived glucose into green hydrogen and key bioplastic building blocks. The project will design high-entropy oxide catalysts with efficient solar and mechanical energy responses to enhance this conversion. Advanced modelling and spectroscopy will reveal the reaction mechanisms, supporting a practical prototype for decentralised biomass conversion.

Objective

Europe generates over 144 million tonnes of cereal straw each year, much of which is open-burned or underutilised, causing CO2 emissions and resource loss. Meanwhile, demand for sustainable polyesters is rapidly growing across textiles and packaging. A major bottleneck is the green synthesis of 2,5-furandicarboxylic acid (FDCA), a key monomer for bio-based polyesters.

The proposed proejct, PHOENIX, introduces a novel piezo-photocatalytic cascade to convert wheat straw-derived glucose into FDCA and green hydrogen under ambient conditions. By combining solar and sustainable mechanical energy sources (wind, tidal, ultrasound) with high-entropy perovskite oxides tailored for band-gap alignment and strong piezoelectric response, the project enables efficient charge separation for selective oxidation and water splitting without harsh conditions.

While piezo-photocatalysis has shown promise, its reaction pathways and active-site dynamics remain poorly understood. PHOENIX will address this by integrating operando spectroscopy, piezo-response mapping, and multiscale modelling to uncover the fundamental mechanism of photo-piezo synergy and translate it into practical design rules. The final goal is to deliver a TRL-6 bench-top prototype for decentralised biomass conversion, advancing EU priorities in climate-neutral materials, circular bioeconomy, and sustainable textiles.
