Recent decades have witnessed accelerated growth in the demand for construction aggregates in Taiwan. The ecological pressures caused by riverbed mining of aggregates have resulted in shortages in domestic supply. Simultaneously, Taiwan must contend with the accumulated generation of construction wastes. Industrial ecology offers, solutions that recover resources from construction wastes. For example, in areas of high-density urban construction, the use of crushed concrete can be economically attractive. To investigate environmentally sound and economically feasible solutions for satisfying future demand, researchers at National Taiwan University and Columbia University propose a study of the long-range consequences of utilizing domestic supply sources including construction waste. © 2001 Elsevier Science Ltd.
