In these pages, case studies of waste characterization and waste management have been collected to provide data on the performance of the characterisation methods and closure technologies. Case studies presented will show both successful and unsuccessful use of various technologies. Stucture of the case study articles is based on the case study evaluation template.

Case studies on the use of characterization methods

Use of field studies in evaluating drainage quality from waste facilities:

• Lysimeter study of explosives originated nitrogen and in-situ sulphide oxidation

Waste management case studies

• ARD control using waste rock layering – Samatosum mine site
• Subaqueous disposal of tailings in a waste management facility – Stekenjokk mine site case study
• Waste management for mine closure – Aitik Cu mine, Sweden
• In-pit backfilling of waste rocks under dry cover – a case study from Kimheden Cu mine, Sweden
• Design, construction, instrumentation, and monitoring of pilot scale waste rock cover systems: concept review and case studies
