Abstract

On a local scale, municipalities often incur high costs as a result of the illegal dumping of construction and demolition waste (CDW), due to gaps in awareness and training, a lack of adequate oversight actions or infrastructure and equipment. Moreover, there is a loss of resources, failing to close the loop of the circular economy. Six participatory workshops were implemented in 2021, via videoconference due to the Covid-19 pandemic, in a rural Portuguese region, to understand the contribution of local scale dynamics in the promotion of CDW management from an operational perspective. Three of them were dedicated to municipal technicians (39 participants, on average) and the other three to representatives of micro and small construction companies (25 participants, on average). The results reveal that strategies must rely on investment in local solutions to optimise logistics and cost issues, cooperation between stakeholders, and improving the market for recycled aggregates. Also, support for information, awareness, and training is essential, focusing on good practices onsite and oversight procedures. Additionally, municipalities were involved in the prioritisation of legal framework issues, and micro and small construction companies concerning the determinants contributing for their behaviour change. These findings contribute to solving gaps in the literature, useful for researchers and decision-makers in rural or less developed areas.
