141671 - No2 Emission Modeling From Biomass Gasification: A Case Study in Rural Community of Batata, Municipality of Tierralta, Córdoba, Colombia. 

This research focuses on the modeling of NO2 emissions, a prioritized pollutant, originating from a residual biomass gasification facility located in Batata, Tierralta, Córdoba, Colombia. The primary objective of the plant is to mitigate the practice of open burning of organic wastes, reduce greenhouse gas emissions, and provide electricity to isolated communities in order to improve their quality of life. Despite the sustainability condition of biomass as an energy source, some concerns arise regarding its gasification process due to the potential emission of NO2, thus posing environmental risks.

In response to data scarcity challenges, this study employs a comprehensive methodology that integrates emission source analysis through stoichiometric calculations and mass balances obtained from chemical reaction analysis. Additionally, meteorological conditions are assessed utilizing data sourced from the NASA POWER® satellite and the Colombian Institute of Hydrology, Meteorology, and Environmental Studies (IDEAM, by its acronym in Spanish) meteorological stations. These data sets are processed using specialized software tools such as Aermet View® and AerMod View® to simulate dispersion patterns and analyze NO2 concentrations originating from the gasification plant.

The simulation outcomes reveal that the highest concentrations of NO2 are localized in the vicinity of the gasification activity area. However, these concentrations consistently fall within the permissible standard of 200 µg/m³, as mandated by relevant environmental regulations. Further examination suggests minimal health risks to the local population, as NO2 concentrations within the town center adhere to safety standards. Moreover, the study indicates that annual NO2 concentrations do not exceed the 50 µg/m³ threshold, affirming that the operational activities of the plant do not pose adverse effects on the well-being of nearby populated areas.

The study's results underscore the environmental viability of establishing a biomass gasification plant in the region. By demonstrating that NO2 emissions remain within acceptable limits, the research highlights the project's potential to positively contribute to waste management and energy production in remote communities without negatively impacting populated centers. Additionally, the study emphasizes the significance of adopting sustainable practices aligned with environmental and public health objectives.

In conclusion, the proposed biomass gasification plant in Batata, Tierralta, Córdoba, Colombia, emerges as a feasible solution to address the challenges associated with open burning and energy scarcity in remote communities. Through a meticulous examination of NO2 emissions, this study affirms that the operation of the gasification plant can be conducted within environmentally safe parameters, thereby supporting its implementation as a sustainable waste management and energy production initiative.
