The first edition of this ICE design and practice guide became one of the most popular ICE publications after it was published in 1994. Since the first edition, there has been a multitude of legislation on the environment and the adoption of many of the principles of the European Landfill Directive. This has meant specialists, regulators and engineers are grappling with interpretation of guidance frameworks, new levels of testing accuracy and increased public perception of environmental damage. This new edition provides an up-to-date overview of the main principles and important aspects of a complex subject.
