From linear to circular : advancing resource efficiency in the built environment in remote and arid regions. The case of the town of Hotazel

Abstract

The transition from linear to circular spatial economies represents a pivotal shift towards resource management practices in the built environment. This thesis explores the advancement of resource efficiency in residential built environment within remote and arid regions, focusing on the town of Hotazel as a case study. Hotazel, situated in the Northern Cape province of South Africa, serves as an economic hub driven primarily by manganese mining activities. With its arid and remote location, the town faces challenges related to resource management and environmental management. Through a comprehensive literature review and analysis of existing literature, this study investigates the principles of circularity applicable to residential construction in such challenging environments. Key research questions explore the guiding principles of circularity, alternative construction systems aligned with circular economy principles, and strategies promoting resource efficiency. The findings highlight the importance of integrating circular design practices, enhancing waste management systems, and optimizing resource utilization to mitigate environmental impact allowing for resilience in remote arid regions. This research contributes to the discourse on circular principles adoption in arid and remote regions, offering insights and strategies for transitioning towards circular spatial economies in the built environment.
