Speciation and Leachability of Zinc in Energy-From-Waste AIr Pollution Control Residues and Effects of Partial Neutralisation

Key Points

• The aim is to investigate the speciation and leachability of zinc in air pollution control residues before and after partial neutralisation.
• Analyzed seven UK air pollution control residues from municipal solid waste combustion.
• Examined zinc speciation before and after partial neutralisation using acid.
• Investigated changes in leachability post-neutralisation.
• Results indicated changes in zinc speciation following neutralisation.
• Leachability of zinc was altered, suggesting reduced ecological risk after treatment.
• Data supports the potential for improved management of waste materials.
