A few highlights (from my perspective)
• Few papers on constructed covers, scaling factors, and climate-
related topics
• More postgraduate research papers
• Fewer case studies
• More open discussion/acceptance of the limitations of models
• More papers on coal mines and pit lakes
What was different this time?
• Kinetic tests (including NAG) tailored to the questions asked
and the mineralogy of waste
• Scaling laboratory to field remains a challenge
• Real opportunities for life cycle approach for reducing liabilities
and unlocking the value of waste
• Accepting and acknowledging the limitations of models
• Opportunities for data sharing
