Abstract

The Construction and Demolition (C&D) industry is very close to various waste management issues as the generation of waste is inevitable in every construction. In Indonesia, to make an applicable implementation of C&D Waste Management, the improvement must be made by looking into the actual field process. The improvement uses DMAIC as the lean tools and VSM to state the current process of material from its delivery on the site into a waste. Waste that is being monitored is the most used materials in the case study project which are concrete. A notable project was taken for the study as it will help other structure projects to imitate the down-to-earth future state, aiming at the reduction of waste generation rate and also business process improvement. The result shows that the process of concrete from orders to waste took eight steps, and three of them are improved, producing 3% lesser waste from the current state. The best scenario WGR were analyzed to also answer the stakeholder interest within the case study.
