Every year, 300,000 to 400,000 homes are demolished in the United States. That means that every day, anywhere between 800 and 1,100 homes are visited by bulldozers. This leads to an enormous amount of demolition waste that eventually ends up in our nation's landfills. Every year, the US Environmental Protection Agency (EPA) publishes an "Advancing Sustainable Materials Management: Facts and Figures Report." In 2017, this report showed that around 569 million tons of construction and demolition debris was generated in the United States. That adds up to more than twice the total amount of municipal solid waste. While construction waste is undoubtedly a problem (and also a source of salvaged materials for home construction or remodeling), over 90 percent of this debris comes from the demolition of residential and commercial buildings.
A major concern of the sustainable building movement is how to limit the embodied energy that goes into the construction of a home. Exploration of the carbon footprint of houses has mostly been confined to energy efficiency measures. However, the greenhouse gas emissions embodied in the materials that go into the home is a significant contributor to the overall carbon footprint.
Opting to use salvaged construction materials from the demolition of older buildings can significantly prolong the life cycle of these building materials. This recycling or "upcycling" process can help reduce the construction industry's demand for raw materials and lower the embodied energy associated with any home construction project. One home demolition company in Australia estimates that upwards of 98% of all materials in homes destined for demolition can find a new use and purpose.
Below, we offer a series of innovative, creative, and practical ideas for incorporating salvaged building materials into a unique and modern home design.
