Summary: The EPA contracted Ipsos B&A to conduct research to understand the attitudes and practices towards waste circularity within the Construction and Demolition (C&D) industry in Ireland. Through interviews with those working in the construction sector, this work sought to identify the attitudes to waste generation, the drivers for excessive waste in the sector and identifying the barriers and opportunities to reducing waste generation (including reuse) from design stage (client scope/specifications) to delivery of infrastructure projects. 14 in depth interviews were completed in August/September 2024. The sample included clients, design/engineers as well as contractors in the industry.
