Introduction<\/h2>\n
The valorization of captured CO\u2082 represents a major challenge for the ecological transition and the chemical industry. The RIPCO2 project, led by HES-SO Valais-Wallis and the iPrint institute in Fribourg, offers a disruptive breakthrough: transforming CO\u2082 into carbon monoxide (CO) using a technology combining inkjet printing and light. This innovation opens new perspectives for green chemistry and local carbon valorization. <\/div>\n

A central challenge: what to do with captured CO\u2082?<\/h2>\n
Carbon capture is essential in climate strategies, but the question of its utilization remained a bottleneck. RIPCO2 addresses this challenge by converting CO\u2082 into an industrial resource, through collaboration between the Industrial Systems Institute of HES-SO Valais-Wallis and the iPrint institute of the School of Engineering and Architecture of Fribourg. <\/div>\n

An unprecedented technological process<\/h2>\n
The innovation is based on inkjet printing of metallic precursors, followed by instantaneous transformation into nickel nanoparticles via a xenon flash lamp. “Instead of making nanoparticles with multi-step processes, we print, we flash the metallic precursors with our lamp, and we obtain a nanoparticle,” explains Professor Mathieu Soutrenon. This process radically simplifies the production of catalysts for CO\u2082 conversion. <\/div>\n

Industrial advantages and applications<\/h2>\n
The process stands out for its speed (a few seconds), low energy consumption, sustainability (use of nickel, an abundant metal), and its capacity to be industrialized on a large scale (continuous roll-to-roll production). The CO produced serves as a key intermediate in green chemistry, particularly for the synthesis of pharmaceuticals, synthetic fuels, and bio-based molecules. <\/div>\n

Toward industrialization and impact for WasteOlas<\/h2>\n
After a laboratory development phase, RIPCO2 now aims for scale-up with a stack system, multiplying CO production. For WasteOlas, this advancement validates the strategy of local CO\u2082 valorization (CCU): “CO\u2082 is not waste, it is a resource.” The Swiss ecosystem is moving in the same direction, confirming the market opportunity for green chemistry and synthetic fuels. <\/div>\n

Conclusion<\/h2>\n
The RIPCO2 project illustrates the growing maturity of carbon valorization technologies and reinforces WasteOlas’s strategic positioning. Swiss innovation in converting CO\u2082 into high-value molecules paves the way for sustainable and competitive industrial solutions. <\/div>\n
