As the imperative to shift towards a net-zero world becomes more urgent and the importance of maintaining productivity and efficiency across sectors grows, an increasing amount of research is delving into the complexities of clean energy. Within the circular bioeconomy, efforts are currently in progress to harness energy from processes and enhance the adoption of carbon-free energy sources. The aim of this research is to pinpoint both challenges and opportunities, laying the groundwork for effective policies that optimise processes and facilitate a seamless transition.
