The first edition described the concept of Integrated Waste Management (IWM), and the use of Life Cycle Inventory (LCI) to provide a way to assess the environmental and economic performance of solid waste systems. Actual examples of IWM systems and published accounts of LCI models for solid waste are now appearing in the literature. To draw out the lessons learned from these experiences a significant part of this 2nd edition focuses on case studies - both of IWM systems, and of where LCI has been used to assess such systems. The 2nd edition also includes updated chapters on waste generation, waste collection, central sorting, biological treatment, thermal treatment, landfill and materials recycling.

This 2nd edition also provides a more user-friendly model (IWM-2) for waste managers. To make it more widely accessible, this edition provides the new tool in Windows format, with greatly improved input and output features, and the ability to compare different scenarios. A detailed user's guide is provided, to take the reader through the use of the IWM-2 model, step by step. IWM-2 is designed to be an "entry level" LCI model for solid waste - user-friendly and appropriate to users starting to apply life cycle thinking to waste systems - while more expert users will also find many of the advanced features of the IWM-2 model helpful. IWM-2 is delivered on CD inside the book.

First published in 1992, the purpose of this book is to identify and describe the most important factors that must be considered in making decisions about the optimal ways to provide access to information - in short the best way to use the humans, the machines, and the intangible resources known as information, particularly at the organizational level. In recent years executives have begun to outsource computing and telecommunications functions primarily to control costs. Traditional libraries and information centres have been disbanded in favour of service contracts or outright leasing of staff. Both the private and public sector are examining their information service operations from the point of view of cost effectiveness. Decisions about owning versus leasing of information are being made daily. Decision makers are finding that they must deal differently with funding and budgeting of information systems and libraries than they have in the past. New paradigms for these service functions already exist. Not only have corporations and governments begun to contract out entire information service operations, but libraries themselves have begun to consider the costs, effectiveness, and implications of outsourcing some of their operations and services. This book provides a framework for decision-makers to view and review information services within their organizations. Entire units, components of libraries and information centres are defined and untangled so that the widest variety of organizations can analyse their own environments. Although there is a minimal use of library and computing jargon, a short glossary at the end explains terms for which there is no simple English language substitute. Each chapter is accompanied by comments from a broad range of experts in the information field.
