Abstract: The present invention discloses a system and process for utilising carbon dioxide emissions from industrial chimneys as a source of algal biomass. Stack gas from an industrial facility is intercepted before release to the atmosphere. An air separation unit supplies oxygen to a combustion chamber, and the resulting exhaust gases are cooled in heat exchangers to condense water vapour. The remaining carbon dioxide-rich gas is purified, compressed and supplied to a microalgae cultivation unit, such as an open pond or photobioreactor, where the microalgae fix carbon dioxide through photosynthesis. The algal biomass is harvested by filtration, sedimentation or centrifugation, then dried and processed into powder, granules or liquid form. The resulting organic biofertilizer enhances soil fertility and crop productivity while reducing reliance on chemical fertilizers. The invention integrates carbon capture and biological utilisation in a single closed-loop process. The process integrates capture and utilisation in one sequence, offering an economical alternative to conventional carbon storage. The arrangement is modular, can be retrofitted to existing stacks with limited modification, and is suited to a range of industrial operators seeking a sustainable route for emission reduction and agricultural input production.
