Incomplete combustion processes can emit organic pollutants, metals, and fine particles. Combustion by-products represent global human and environmental health challenges that are relevant not only in heavily industrialized nations, but also in developing nations where up to 90% of rural households rely on unprocessed biomass fuels for cooking, warmth, and light. These issues were addressed at the Seventh International Congress on Combustion By-Products, which convened 4-6 June 2001 in Research Triangle Park, North Carolina. This congress included a diverse group of multidisciplinary researchers and practitioners who discussed recent developments and future goals in the control of combustion by-products and their effects of exposure on human and ecologic health. Participants recommended that interdisciplinary, coordinated research efforts should be focused to capitalize on the important potential synergisms between efforts to reduce the adverse human health effects linked to exposures to combustion by-products and broader efforts to reduce greenhouse gas emissions and save energy through efficiency. In this article we summarize the principal findings and recommendations for research focus and direction.

Review on Gallium in Coal and Coal Waste Materials: Exploring Strategies for Hydrometallurgical Metal Recovery.

Molecules

December 2024

Faculty of Non-Ferrous Metals, AGH University of Krakow, Al. Mickiewicza 30, 30-059 Krakow, Poland.

Gallium, a critical and strategic material for advanced technologies, is anomalously enriched in certain coal deposits and coal by-products. Recovering gallium from solid residues generated during coal production and utilization can yield economic benefits and positive environmental gains through more efficient waste processing. This systematic literature review focuses on gallium concentrations in coal and its combustion or gasification by-products, modes of occurrence, gallium-hosting phases, and hydrometallurgical recovery methods, including pretreatment procedures that facilitate metal release from inert aluminosilicate minerals.

Firecrackers are a vital element of cultural festivities that happen worldwide. However, the hazardous by-products they emit have a significant impact on environmental pollution, leading to the greenhouse effect and climate change. Aluminium powder serves as the fuel in the traditional flash powder mixture, nitrate of potassium serves as an oxidizing agent, and sulphur acts as the igniter at exact concentrations.

Article Synopsis
  • Thermochemical treatment of oily sludge (OS) shows potential for recovering resources and energy, but concerns over pollutant emissions limit its advancement.
  • This study compares the environmental impacts of OS treatment methods (pyrolysis, gasification, and combustion), focusing on pollutants in liquid, gas, and solid products, revealing differing release behaviors and composition among the processes.
  • Results indicate that higher treatment temperatures (like 950 °C) lead to greater concentrations of harmful pollutants (N-, S-, and Cl-containing) and affect organic matter content in residues, highlighting the complexity of managing emissions.

Article Synopsis
  • The Chinese iron and steel industry heavily relies on coal and conventional smelting processes, leading to significant emissions of heavy metals like mercury, arsenic, and lead, posing environmental and health risks.
  • The study found that coal and iron ore are the main sources of these heavy metals, with their chemical transformations influenced by temperature changes during the smelting processes.
  • Sintering is responsible for most mercury emissions, while arsenic and lead mainly come from the blast furnace process, highlighting the need for targeted reduction technologies and better waste management in future policies.
