Air pollution, particularly from manufacturing and energy production facilities, presents a significant environmental challenge. Recognising this issue, we were inspired by Carbon Capture, Utilisation, and Sequestration (CCUS) technologies to find a solution. CCUS involves capturing CO2 emissions at their source, utilizing the captured carbon, and permanently storing it. We aimed to enhance this technology by developing a more efficient and comprehensive system. This led to the creation of our Pollutant Capture and Storage Technology (PCST).
By improving upon traditional CCUS methods, we designed a system that effectively degrades CO2. The PCST operates through three main stages: collection, capture, and storage. This innovative approach not only mitigates air pollution but also contributes to a cleaner and healthier environment. We initially envisioned a large chamber where various microbes could collaborate to efficiently collect carbon emissions. However, this idea proved counterproductive due to the distinct ecological environments that different microbes require to function optimally. This led us to rethink our strategy and focus on a more targeted approach.
Our solution started to take shape by incorporating genetically engineered microbes specifically designed to capture and sequester pollutants. A key component of our technology involves using Cyanobacterium Prochlorococcus, one of the most abundant microbes on the planet, which captures sunlight and absorbs CO2 while producing oxygen through photosynthesis (Ulloa et al.). On top of that, we incorporated Methanotrophic bacteria, Thiobacillus , and Pseudomonas bauzanensis DN13-1 for their unique abilities to process and degrade CO2. As we developed our system, we faced significant challenges, particularly in culturing cyanobacteria. To address this, we made use of a photobioreactor, an advanced system that ensures cyanobacteria receive the necessary light for optimal function. This innovation refined our initial approach, enabling us to fully use the potential of cyanobacteria in our pollutant capture process.
In the storage stage, the sequestered CO2 is permanently stored in underground formations. Our system also separates and releases purified oxygen (O2) and nitrogen (N2), contributing to a cleaner atmosphere. Our final product, the PCST, demonstrates our commitment to creating a cleaner, healthier environment. This innovative system, which integrates advanced CCUS technologies with biotechnological innovations, is capable of significantly reducing CO2 emissions at their source. Our solution not only captures and sequesters CO2, but also sustainably utilizes the captured gasses, marking a considerable advancement in the fight against air pollution.
