Abstract: Construction and Demolition (C&D) waste constitutes a large part of the total waste generated in Malta with an amount of 68.9% (NSO, 2017). Directive 2008/98/EC obliges Member States to recover 70% of C&D waste generated by 2020. The Waste Management Plan for the Maltese Islands 2014-2020 aims to increase awareness and undertake efforts to manage C&D waste. Malta is largely dependent on backfilling in disused quarries. In order to upgrade the recovery action to a higher status within the waste hierarchy, this study explores measures for C&D waste management in the context of four criteria; economic, environmental, social and ease of implementation, with the intention of formulating viable reduce, reuse and recycle strategic plans. By means of an interview, stakeholders of the construction industry set the background against which C&D waste management strategies can be discussed so as to deviate from the linear traditional approach of the disposal of C&D waste and move towards a circular economy. During a second interview with major developers, contractors, architects, engineers, and government entities, the list of circular strategies was ranked. The strategies preferred most resulted from allocated weightings according to economic feasibility, environmental impact, social considerations and ease of implementation on the basis of the stakeholder' s knowledge and experience in the Maltese construction industry. Multi-Criteria Decision Analysis (MDCA) was used to examine the order of preference of the proposed strategies. The study concludes with an analysis of some of the proposed strategies on the basis of the findings.
