Advancements in Emission Control Technologies: Innovations and Challenges in Urban Air Quality Management

Abstract

The growing concerns over air pollution and climate change have propelled emission control systems (ECS) to the forefront of environmental engineering and regulatory efforts. This review explores recent advancements in ECS technology, focusing on their effectiveness, challenges, and future trends. As industries and urban areas continue to expand, the need for robust ECS becomes increasingly critical to mitigate the adverse effects of pollutants on public health and the environment. We delve into various systems, including catalytic converters, particulate filters, and emerging technologies such as electrification and hydrogen fuel cells. Furthermore, we examine the integration of ECS with renewable energy sources, enhancing their effectiveness in reducing greenhouse gas emissions. The article also addresses regulatory frameworks, public perception, and the role of policy in driving innovation in emission control technologies. By highlighting key research findings and case studies, this review aims to provide a comprehensive understanding of the current state of ECS and the pathways to a sustainable and cleaner future.
