Construction and Demolition Waste Recycling in a Broader Environmental Perspective
The scope of this chapter is to analyse the prospects for recycling the mineral fraction of construction and demolition wastes as aggregates within the frame of sustainable construction, and to identify research needs. Sustainable construction is defined by life-cycle evaluation of environmental, economic and social aspects, and is dependent not only from production processes but also from local constraints and market alternatives. Environmental performance of recycling construction and demolition waste must be evaluated cradle-to-grave, using multi-criteria life-cycle assessment tools. Economic performance depends on life cycle cost and has to consider externalities. Social assessment can be done using the new social life cycle assessment methodology. The flows of aggregates and construction waste in the near future, as well as the presence of informal activities in the supply chain, have strong influence on the sustainability in every location. Attractiveness of recycling CDW as aggregates will depend of local environmental, social and economic conditions. Examples of life cycle thinking applied to CDW aggregates are given and research needs discussed.
