Abstract
Agricultural waste, including Corn cobs, rice straw and chicken manure, are common agricultural waste in the Philippines. In this study, it was used as a bioresource material for photocatalysis. The mixture of agricultural waste with titanium dioxide was put inside the 1000L capacity IBC tank for decomposition and production of concentrated carbon dioxide. It was placed under direct sunlight for faster decomposition and UV light was installed for a continuous process at night.
The optimum performance of CO2 harvester was evaluated at different parameters, which includes, temperature, daily CO2 produced, volume of CO2 produced and flowrate. For validation, the CO2 Harvester were installed in the greenhouse and the CO2 injected were evaluated based on the carbon dioxide condition after injection. A CO@ sensor were used to monitor the amount of CO2 concentration inside the greenhouse.
As a result, the total volume of carbon dioxide collected was 195L, 178 liters under sunlight conditions while 17 liters under UV light conditions. Which concludes that the production under UV light conditions is not as effective compared to sunlight. The CO2 collected was then injected inside the greenhouse through drip irrigation for 3 minutes at 6:00 AM. A CO2 sensor were used to monitor the amount of CO2 concentration inside the greenhouse. The highest collected data of concentration was 537 ppm and the lowest is 400 ppm. The study shows that the used of CO2 harvester inside the greenhouse can boost carbon dioxide that helps the production and growth of plants through photosynthesis.
