An integrated sustainability analysis of construction waste management strategies

A multi-criteria optimization model has been developed to propose economically sound and environmentally benign construction waste management strategies for LEED© certified green buildings. First, an input-output based hybrid life cycle assessment model has been developed to quantify the net environmental impacts of different waste management options such as recycling, conventional landfilling and incineration. After quantifying the net environmental burdens associated with these waste management alternatives, a compromised programming model has been utilized to determine the optimum recycling strategy considering environmental and economic impacts, simultaneously.
