This report presents Oxalynx, a climate-tech start up based on the Carbon Catch Air bioreactor (an invention from ITQB NOVA) that captures CO₂, converting it into oxaloacetate, a valuable industrial feedstock. By bridging carbon capture and bio-based production, Oxalynx offers a decentralized, low-energy, and scalable alternative to storage-based models. Its dual-revenue model combines CarbonCapture-as-a-Service and Oxaloacetate Valorization, evolving into biofuel production. Aligned with global climate goals, Oxalynx addresses the need for accessible carbon removal while unlocking value chains across the bioeconomy.engStart upSustainabilityCarbon captureCarbon valorizationBioeconomyEnvironmental impact reductionSustainable innovationBusiness planCO2 utilizationmaster thesis204128196
