Abstract
Globally, the construction, renovation, and demolition sectors are increasingly responsible for growing resource demand and structural waste, even given progress in energy efficient technologies, 'green' building design, and local planning regulations. In response, the Circular Economy has become a popular agenda in the construction, renovation, and demolition sector as it offers a new model that not only maximizes materials reuse and recovery but also reframes urban systems and the built environment in a closed-loop (cradle-to-cradle) paradigm. In particular, popular visions of the Circular Economy promote, among other actions, 'optimizing' the end-of-the-life of buildings and their materials. Deconstruction (i.e. piece-by-piece demolition) is one key optimization strategy that has received increasing, yet limited, attention by researchers. This paper traces the development of an incipient deconstruction sector in Vancouver, focusing on the possibilities and challenges of deconstruction and material recovery practices as viable strategies for a transformative Circular Economy. I investigate two related aspects: first, the emerging policy landscape surrounding green demolition, and second, the development of 'unbuilding' practices and more formal 'Deconstruction Hubs'. Overall, the paper finds that while these developments represent fundamental steps towards a more sustainable built environment, there remain a number of significant social, political and economic limitations that must be confronted if we are to meet the growing demands for more radical sustainability and 'circularity' not only in Canadian construction, renovation, and demolition sectors, but across Canadian cities and beyond.
期刊介绍:
Environment and Planning A: Economy and Space is a pluralist and heterodox journal of economic research, principally concerned with questions of urban and regional restructuring, globalization, inequality, and uneven development. International in outlook and interdisciplinary in spirit, the journal is positioned at the forefront of theoretical and methodological innovation, welcoming substantive and empirical contributions that probe and problematize significant issues of economic, social, and political concern, especially where these advance new approaches. The horizons of Economy and Space are wide, but themes of recurrent concern for the journal include: global production and consumption networks; urban policy and politics; race, gender, and class; economies of technology, information and knowledge; money, banking, and finance; migration and mobility; resource production and distribution; and land, housing, labor, and commodity markets. To these ends, Economy and Space values a diverse array of theories, methods, and approaches, especially where these engage with research traditions, evolving debates, and new directions in urban and regional studies, in human geography, and in allied fields such as socioeconomics and the various traditions of political economy.
