MINERALOGY has many applications in the business of waste and waste disposal:

• precipitation of minerals and adsorption of elements and compounds to mineral surfaces can serve to immobilize pollutants or concentrate them for recycling
  
• release of elements and compounds can occur by the converse processes of dissolution and desorption
  
• minerals can act as impermeable barriers between pollutants and the environment
  
• minerals can be used as analogues to determine the long-term stability of engineered materials used for the encapsulation of waste.
  

The Applied Mineralogy Group of the Mineralogical Society organized a meeting ‘The mineralogy of waste and waste disposal’ held at the British Geological Survey, Keyworth, Nottingham, on 25^th September 2000. The meeting attracted members of both the academic (Earth Science, Chemistry and Material Science departments) and industrial communities. A wide variety of papers was presented dealing with such diverse issues as nuclear waste disposal and the recycling of phosphorus from wastewater. Seven of the papers are collected here.

One widely suggested method of disposing of radioactive waste is to immobilize it in cement, either by incorporating the components of the waste into the cement structure or by encapsulating the waste with cement. Glasser (2001) reviews the mineralogy and chemistry of cements and impure limestones metamorphosed . . . [Full Text of this Article]
