The PhotoReAct project set out to transform the energy and resource demands of the chemicals industry by harnessing light as a sustainable and efficient energy source for chemical transformations. Over the course of the project, we have successfully implemented this vision through a structured program of cutting-edge research, interdisciplinary collaboration, and comprehensive training.
From the start of the project, our consortium, comprising leading academic institutions, SMEs, and industrial partners, focused on leveraging photochemical processes to produce fine chemicals, pharmaceuticals, agrochemicals, and specialty chemicals with greater energy efficiency and reduced reliance on fossil fuels. We have achieved substantial progress in process intensification using photoredox catalysis, continuous-flow photochemistry, and the application of digital tools such as machine learning and Bayesian Optimization to optimize reaction conditions. In many cases, these approaches delivered results that outperformed benchmarks from the existing literature in terms of both yield and selectivity.
Key outcomes of the project include:
• The development of novel photochemical methodologies and reactor technologies suitable for scale-up;
• The integration of automation and machine learning into photochemical workflows, enabling faster and more efficient reaction development;
• Significant progress in sustainability, including reduced energy consumption and minimized environmental impact of selected chemical processes;
• A strong portfolio of publications, with several still under preparation or review;
• The establishment of long-term collaborations across academic and industrial partners, extending beyond the project duration.
Crucially, the project trained 15 Early Stage Researchers (ESRs), equipping them with a rare combination of scientific, technical, and transferable skills. Many of them have transitioned into impactful roles in academia and industry, carrying forward the project’s innovations into the next phase of development and application.
Exploitation and Dissemination:
Exploitation efforts have focused on embedding developed photochemical processes and workflows into partner organizations, particularly SMEs, and supporting their potential commercialization. Several tools, protocols, and reactor designs have been adopted by industry partners, and ongoing collaboration networks ensure sustained innovation beyond the project. Dissemination was carried out through peer-reviewed publications, conference presentations, public engagement activities, and training events. The PhotoReAct website and communication materials served to amplify project visibility and ensure open access to relevant outcomes where appropriate.
In conclusion, PhotoReAct has delivered on its ambitious objectives, demonstrating how photochemistry and digital tools can drive greener, more efficient chemical manufacturing, while also laying the groundwork for ongoing impact through trained researchers, technological outputs, and industrial partnerships.
