The papers from this IMechE conference deal with all aspects of environmental management relating to land, water and air, describing the technologies applicable to these areas. With the advent of Landfill Tax and the growing realization that the landfilling of unprocessed wastes may pose environmental problems for future generations, there is considerable interest in alternative and /or improved methods of waste management including minimization, recycling and energy recovery. Environmental concerns are raising awareness amongst engineers and also highlighting opportunities for new products, systems and operating techniques. The papers identify these opportunities through current technologies, on-going research and deveopment and feedback from case studies.
