In architecture we are so caught up in creating something new, we often forget about what happens at the end of a building’s life cycle—the unfortunate, inevitable demolition. We may want our buildings to be timeless and live on forever, but the harsh reality is that they do not, so where is all the waste expected to go?
As with most non-recyclable waste, it ends up in the landfill and, as the land required for landfill becomes an increasingly scarce resource, we must find an alternative solution. Each year in the UK alone, 70–105 million tonnes of waste is created from demolishing buildings, and only 20% of that is biodegradable according to a study by Cardiff University. With clever design and a better awareness of the biodegradable materials available in construction, it’s up to us as architects to make the right decisions for the entirety of a building’s lifetime.
