                  <dc:description>Food waste is a critical contributor to global greenhouse gas emissions, with produce spoilage accounting for a significant portion of discarded food. This thesis investigates the design and testing of climate-controlled produce storage bins aimed at extending shelf life and reducing methane and carbon dioxide emissions during ripening. The project is part of a broader effort to support sustainable food systems and increase access to fresh produce through applications like Verdantt Fresh’s refrigerated vending machines. The research is divided into two core components: mechanical control of internal temperature and humidity, and chemical monitoring of gas emissions during ripening. The mechanical experiments tested various thermoelectric module configurations and vent placements to regulate bin temperature, but all configurations failed to achieve the cooling range needed for optimal storage, indicating the need for redesign. The chemical experiments evaluated the impact of activated carbon on methane and carbon dioxide levels in sealed bins containing ripening bananas. Results showed a 53.1% methane increase in control conditions compared to just 13.1% in bins with activated carbon, suggesting slowed spoilage. While carbon dioxide data was limited, one trial showed a decrease over time in the presence of activated carbon. These findings support further investigation into passive gas filtration and improved airflow designs. Future work includes redesigning the cooling system, testing additional activated carbon forms, and integrating findings into modular bins that could be deployed in vending machines or home refrigerators. Ultimately, this research aims to create affordable, sustainable storage solutions that reduce food waste and its environmental impact while improving access to fresh, healthy produce.</dc:description>
