Components and structures of the pillars of sustainability.

The focus of this Special Volume (SV) of the Journal of Cleaner Production is “Sustainable Development of Energy, Water and Environmental Systems”. It is of interest to practitioners in various branches of industry including the energy and water & wastewater sectors and environmental services, governmental policy makers, researchers, educators and the general public. The purpose of this SV is to increase public awareness of key issues of sustainable development and to stimulate exchange of research results, practical experience and new ideas among actors involved in investigating, planning and implementing sustainable development, regarding energy, transport, water, environment and production systems. The SV is focused upon four main fields that are of strategic importance to the sustainable development: energy resources and energy management, water management and wastewater treatment, environmental engineering and management, and promotion of sustainability concepts. The systems under consideration are differentiated in scale, ranging from countries or groups of countries, through regions or branches of industry, municipalities or industrial plants, down to single processes or equipment pieces. Examples of on-going research including case studies are presented along with examples of innovative practical solutions. In the energy field, examples are presented of the development and applications of energy systems analysis, planning and design methods and tools, which can be used to analyse the coherency of the whole systems and to augment the creation of sustainable energy policies and action plans on a large scale, as well as small-scale systems for efficient energy management. Regarding water issues, water management in water stressed regions is discussed indicating the usefulness of advanced mathematical models that take system dynamics and the stochastic nature of rainwater availability as planning tools, and LCA-based methods for assessing the diverse water supply alternatives within a dry region. In the field of environmental engineering and management, large-scale systems for solid waste collection, management and recovery are analysed, and the formation of air pollutants in industrial sources and diesel engines is studied by simulation. Finally, sustainable use of biomass resources and the role of sustainability thinking in the investment planning and management are addressed. In each of the four fields, strategically important challenges for future research are identified including the use of advanced mathematical models and multi-criteria analysis for the optimisation, from the sustainability point of view, of the systems for energy and water supply and management, solid waste management and the utilisation of biomass resources.
