Unbuilders deconstructs buildings, instead of demolishing them, keeping at least 80 per cent of building materials out of landfill and reducing carbon footprints.
The demolition industry is one of the largest contributors to pollution in Canada. We need to change this immediately,” says Adam Corneil, Founder and CEO of Unbuilders. Instead of demolition, they deconstruct and salvage the building components and yield less than 5 per cent waste on average.
Every year, 40 per cent of the waste going into landfills around B.C.’s Lower Mainland is from construction and demolition. When an average single-family home in Metro Vancouver is torn down, it creates approximately 50 tonnes of waste which are taken to a landfill or incinerated. Approximately 3,000 houses are demolished annually in Metro Vancouver. While 95 per cent of the materials in those houses could be recycled or re-used, the vast majority are discarded.
Deconstruction keeps at least 80 per cent of building materials out of landfill. While rescuing and selling old growth lumber is a byproduct of the deconstruction process, keeping demolition waste out of landfill is Unbuilders’ main goal. Building homes with re-used materials reduces the carbon footprint of their construction. This practice is a key part of a circular economy, in which resources and materials are recovered and re-used in home construction. Beyond the environmental benefits, a transition from demolition to deconstruction would create approximately 13,300 jobs in the Lower Mainland.
