In the new era of energy transition to a low carbon future, technologies for air pollutant emission control are the key to enabling solid fuel utilization in the power sector in a more environmental and friendly way. While the acid gases such as SO2 and NOx have long been the focus and the control technologies are in a mature state, it is not until the early 21th century that PM2.5 and Hg emissions from power plants received significant attention. In the past decades, great advances have been achieved in scientific understanding and technology development of controlling PM2.5 and Hg emissions from combustion of various solid fuels (coal, biomass, MSW, etc.). There have been a wide range of technologies available, including separate and co-benefit methods. Some of them have been applied in industries, while some are still under development. This special issue aims to provide an excellent forum for scientists and engineers around the world to share and exchange their latest contributions to the understanding of PM2.5 and Hg emissions and the development of related control technologies. Both original papers and review articles are all welcome.


The scope of the Special Issue covers a broad range of topics. They include but are not limited to:

1. Sampling and analytical methods

2. Measurements and modeling

3. Chemistry and physics

4. Quality assurance and quality control

5. Impacts on the environment and human health

6. Control technologies and strategies, such as

  • Electrostatic Precipitator (ESP, wet or dry)

  • Fabric Filter (FF) or Baghouse (BH)

  • Hybrid ESP-FFs

  • Scrubber (wet or dry)

  • Activated Carbon Injection (ACI)

  • Sorbent Injection

  • Halogen Addition

  • NOx Catalyst

  • Co-benefit Methods of Control
