Abstract
The construction industry is increasingly challenged to reduce its waste production, resource consumption and energy emissions. Moving towards more circular and sustainable practices therefore seems imperative. Demolition contractors play a vital role in this move as they need to select waste management strategies for distinct obsolete building elements. Previous research has nevertheless overlooked how demolition contractors can gain insights into the consequences of such strategies. This research therefore adopts a design science research methodology to iteratively develop a decision-support tool for selecting demolition waste management strategies. Through collaborating with a pioneering demolition contractor in the Netherlands, in-depth insights into actual decision-making processes were obtained. A tool was subsequently designed that compares and ranks three different waste management strategies (reuse, recycle and recover) by evaluating their impacts in terms of technical feasibility, economic costs, environmental gain and social gain. This tool enables demolition contractors to make more informed waste management decisions and, as such, offers new opportunities to adopt circular and sustainable demolition methods. PRACTICE RELEVANCE Demolition contractors are pressured to adopt more circular and sustainable methods. This requires these firms to consider waste management strategies other than traditional energy recovery or landfilling. A new decision-support tool offers demolition firms insights into the consequences of different waste management strategies. This tool compares and ranks reuse, recycle, and recover waste management strategies. The tool was demonstrated and evaluated by a demolition contractor in the Netherlands. It was found that the decision-support tool assists in making more informed waste management decisions through illuminating technical feasibility, economic costs, environmental gains and social gains. A suggested ranking of strategies is provided for distinct obsolete building elements. Implementing the tool will require changes to local project routines.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
