| Abstract | Climate-susceptible nations are severely impacted by frequent storms, effects of sea level rise, and seasons with temperatures that already limit worker output. Though agriculture is a vulnerable industry, it can potentially reduce energy-related carbon dioxide emissions through bioenergy production. This study investigates rice straw-based bioenergy with carbon capture and utilization (BECCU) as an agricultural waste management. Using Aspen Plus®, bioenergy conversion of rice straw through power generation or ethanol production shows 574 kW of power, or 131 kg ethanol is produced per ton of rice straw. Following CO2 capture and utilization, 6,748 pieces of CO2-cured bricks, 717.57 kg of methanol, or 1,601.84 kg of urea is produced from the power generation route, and 5,963 pieces of CO2-cured bricks, 565.23 kg of methanol, and 1,265.43 kg of urea is produced in the ethanol route. With the functional unit is defined as the management of rice straw as an agricultural waste, the production of electricity, steam, ethanol, carbon-cured bricks, methanol, and urea provide environmental credits as alternative sources of these products. Overall, power generation followed by CO2-cured bricks shows a negative impact on 14 out of 18 life cycle midpoint indicators and a shorter payback period. Rice agriculture contributes highly to the greenhouse emissions of the agriculture sector, but this study found promising rice straw management practices that could reduce burning and contribute to climate mitigation. While valorizing, rice straw-based BECCU, specifically bioenergy production followed by CO2 curing of bricks as CO2 utilization, is a market-driven, emissions-negative method. |
