The long-term consequences on the environment of materials containing potentially toxic elements must be assessed on the basis of experimental data obtained over short time-scales and from models of the phenomena involved over several tens of thousands of years. Predicting the future is only possible through the study of collection of past events to infer a possible long-term behaviour. However, not everything we would like to predict has already occurred in the past, nor is it necessarily observable under perfectly similar circumstances. Considering natural or artificial analogues permits us to study materials that, even if not homologous, are similar or equivalent to some of the properties of the unknown materials. Examples presented in this paper illustrates the fact that some reactions observed in short-term experiments can be validated over the long term only by examining such natural analogues.

Energy, Waste and the Environment: a Geochemical Perspective
This book provides incentives for further development of sustainable fuel cycles through a novel and interdisciplinary approach to an Earth science-related topic. The main focus is on geochemical concepts in immobilizing, isolating or neutralizing waste derived from energy production and consumption. The book also addresses the issue of using some types of energy-derived waste as alternative raw materials. Moreover, it highlights research on how certain wastes can be used for energy production, an increasingly important aspect of modern integrated waste management strategies. The main objectives are to: (a) identify the most serious environmental problems related to various types of power generation and associated waste accumulation; (b) present strategies, based on natural analogue materials, for the immobilization of toxic and radioactive waste components through mineralogical barriers; (c) discuss modern procedures for reuse of waste or certain waste components; and (d) review the importance of geochemical modelling in describing and predicting the interaction between waste and the environment.
