Abstract
This study aimed to design and construct a prototype capable of capturing carbon dioxide (CO₂) from the air using calcium chloride (CaCl₂), to transform it into calcium carbonate (CaCO₃) and utilize it as natural fertilizer. A quantitative-experimental approach was employed, with testing under controlled environmental conditions and in three urban areas of Tacna, Peru. Three CaCl₂ doses (20 g, 40 g, and 60 g) were evaluated during 5-minute exposures, measuring CO₂ concentration before and after each intervention. Results showed that 40 g of CaCl₂ captured 320 ppm of CO₂, while 20 g and 60 g captured 100 ppm and 240 ppm, respectively. Capture was not linear, indicating that factors like humidity and airflow influence process efficiency. It is concluded that the prototype offers an accessible alternative to mitigate climate change and produce sustainable fertilizers. Its application in rural contexts represents a viable strategy for carbon capture and agricultural soil improvement, contributing to greenhouse gas (GHG) reduction and strengthening sustainable agriculture.
