The implementation of sustainable concept in waste management through project life cycle process in Gold Coast

The issue regarding sustainability has emerged significantly in the construction industry. The appealing concept and the future benefits of sustainability have enamoured people to implement this notion progressively. This situation resulted in a trend in the architectural and engineering world. The Gold Coast city, which is located in the southeast of the Australian state of Queensland, is one of the world leading examples in which a government has put a green legacy as the concern in its development. One of the implementations of its sustainability concept is described in its waste management. This study explores the waste management in Gold Coast city in three stages of the project life cycle (PLC): design, construction, and operation. The cost-benefit analysis in qualitative and quantitative approach will be employed to provide the explanation of cost reduction that is achieved by the implementation of specific actions. However, the result of this study shows that the implementation of waste management does not only benefit in cost, but also many other aspects such as energy, built-environment, diversity, carbon critical design, and community lifestyle. This exploration can be the reference to the best practice of sustainability concept implementation in waste management.
