Environmental pressures have forced a major rethink on the management and use of landfill. The engineering questions are considerable, and have not been discussed much in the literature to date. This new work provides an up to date Handbook on the engineering of landfill materials from design and construction of new facilities to the re-use and development on closed landfill sites.Following the EU Landfill Directive and in response to pressure, the UK now needs to comply with the diversion and separation of biodegradable domestic waste from hazardous waste and to give greater emphasis to the re-cycling of waste materials. This will change the character of landfills in the future as the materials changes. The engineering properties of landfill materials are a function not only of their physical characteristics but also of the chemistry of degradation. Additionally, increasing government pressure to redevelop brownfield land is driving the re-use of landfill. This is making engineers re-think the techniques of disposal of wastes in new landfill to ultimately allow safe redevelopment of these sites. It also prompts the understanding of the characteristics of existing landfills to develop safe engineering solutions.This book provides a reference to landfill characteristics, measurement, analysis and modelling landfill behaviour, recycling materials and engineering design. It presents the background science and engineering methods to solve these issues.
