As cities shrink and sites are slated for demolition, a costly process of demolition and urban consolidation begins, this process could be reversed with the goal of becoming a profitable industry through salvage. There may be a business case in some areas for greater value to be ‘mined’ from a ‘decommissioned’ dwelling than can be earnt from its sale as a standing house.
Unfortunately not all material will be appropriate for salvage and this approach could be carried further through the introduction of a sustainable energy network fuelled by combustible demolition waste. Trigeneration (decentralized combined heat and power plants) fuelled by unsalvageable combustible material from demolished dwellings could help fuel remnant communities in denser areas and new settlements as they emerge to consolidate preservation areas.
By seeing waste as an economic resource, urban decline can be seen as a new resource for local economic gain.
