Waste reduction through incentives : a case study

To motivate construction workers to adopt a waste construction strategy, a reward scheme was implemented. A Stepwise Incentive System (SIS) was used to measure the cost save on purchasing material and controlling waste generation. The key difference of this method is that it harnesses employees' awareness on waste reduction by contributing incentive funding to staff involved in projects producing lower waste levels. The lower the waste, the higher the incentive. The effectiveness of the SIS is shown by using a local case study in which waste can be reduced by up to 23%.
