AI and Machine Learning for Optimizing Waste Management and Reducing Air Pollution

Abstract

Recent advancements in artificial intelligence and machine learning (AIML) can transform waste management and air quality by facilitating the analysis of extensive data sets to predict waste generation trends, optimize collection routes, and enhance sorting and recycling processes. These technologies address significant challenges in urban environments, where inadequate infrastructure and regulatory frameworks contribute to pollution from waste and air quality issues. Unlike traditional methods relying on manual data collection and static models, AIML-driven solutions enable dynamic, real-time analysis, identify pollution sources, and optimize air quality monitoring, helping policymakers implement targeted interventions. The integration of AIML technologies into waste management systems can significantly reduce operational costs and improve the efficiency of recycling programs, leading to a reduction in landfill use and promoting circular economy practices. ML models, especially deep learning models, can simulate air quality outcomes based on various waste management scenarios, informing evidence-based regulations. Furthermore, waste-to-energy technologies embody the synergy between energy production and waste management because AI enhances operational efficiency while reducing harmful emissions. AI optimization in waste-to-energy processes can contribute to reducing greenhouse gas emissions by ensuring that energy recovery is maximized while minimizing pollutants. The existing regulations (such as the Paris Agreement, Nationally Determined Contributions, the Clean Air Act, or the Environmental Protection Act), identifying gaps, and engaging stakeholders in sustainability initiatives are all made possible by data-driven policymaking. Nevertheless, to optimize the advantages of AIML, it is imperative to deal with obstacles such as algorithmic bias (biased trained data, underrepresentation, and algorithm design choices), data privacy (unauthorized access, reidentification risks, and regulatory compliance), and the necessity of interdisciplinary collaboration. Future research should develop inclusive frameworks that allow for equitable access to AI-driven solutions, considering social, economic, and environmental factors. Integrating AIML in waste management can scale global solutions for air quality control, promoting sustainable development, improving public health, and enhancing urban sustainability. © 2025 American Society of Civil Engineers.
