Abstract
The technology to manufacture ‘designer waste’ is now available. This paper examines the very important and positive impact that the International Paste and Thickened Tailings Seminars have had on developing this technology, examines the current technology and challenges, looks at the broader environmental perspective and finally, lists some recommendations. The major conclusion and recommendation is that traditional tailings dams can and should be eliminated for flocculated fine particle suspensions by producing and stacking a designer paste. Reclamation can and should then occur concurrently with the paste stacking.
