CAVI, led by researchers from University of Ljubljana (Slovenia), National Technical University of Athens (Greece) and UBB-TechTransfer at Babeș-Bolyai University (Romania), is one of the supported research teams in the first S3E Start Programme.
The EU recognised biogas as a vital renewable energy source to achieve energy resilience and climate change mitigation goals. Biogas, derived from waste like agricultural & food waste, and sewage sludge through anaerobic digestion, offers applications as electricity and heat generation. By embracing biogas, the EU can significantly reduce its reliance on fossil fuels and energy imports.
Amidst soaring energy prices, the benefits of biogas become even more apparent. Presently, approximately 19,000 biogas plants operate within the EU, with this number expected to double by 2050 — a testament to the growing prominence of this sustainable energy source. Nonetheless, the optimization of waste-to-biogas conversion remains an ongoing challenge. Conventional anaerobic digesters are large and time-consuming. The state-of-the-art technology to enhance biogas production, thermal hydrolysis, is complex and expensive.
With their groundbreaking solution, scientists from Slovenia and Greece have harnessed the power of cavitation, a process that occurs when vapour bubbles form and collapse, generating extraordinary pressures and temperatures, comparable to the Sun’s surface. Leveraging this incredible force, they have developed the revolutionary CAVI Ω reactor — an innovative, compact, and plug-and-play device that significantly reduces construction and operating expenses. The CAVI Ω reactor stands as a true innovation, poised to drive the biogas industry into a new era of sustainability and profitability.
