Innovations and challenges in sustainable management of Construction and Demolition Waste (CDW): proposal to eco-efficient and circular construction
| Resumo: | This dissertation explores the management of construction and demolition waste (CDW), emphasizing sustainable practices, innovations, and the critical environmental impacts of improper waste management, which exacerbate climate change. It highlights the challenges faced by companies, especially SMEs, in implementing effective CDW management due to financial limitations and insufficient recycling infrastructure. Additionally, the limited adoption of advanced technologies like Building Information Modeling (BIM) and Automation underscores the need for greater awareness and financial support to integrate these innovations into waste processes. Drawing on EU waste management data, the study underscores that in 2022, over 61% of the EU's 1,992 million tonnes of waste (including CDW) were treated through recovery methods such as recycling and energy recovery. This makes for a significant improvement from the 45.9% of waste treated in 2004. However, significant disparities exist among member states, with some excelling in recycling while others rely heavily on landfilling. The case of Portugal is no different from some of these countries given that, within the same time frame, less than 50% of its waste was treated, a figure which happens to be below the EU average. This calls for stringent and urgent measures some of which are projected in this study. |
