When buildings are torn down, much of their material ends up as waste, even though a lot of it could be recycled or reused. Efforts to use materials better have mostly focused on the design and construction stages of a building.

What they work on
- Develop a stochastic model of building owners' maintenance, repair and rehabilitation (MR&R) decisions over a building's service life that accounts for the carbon-saving potential of recycled demolition materials.
- Quantify the time-performance and productivity of different demolition methods under varied management and operational conditions, and their effect on material recovery.
- Build a policy-planning framework, applied at the community level in Tallahassee, Florida, that links stakeholder decisions under different environmental policies to maximize recyclable and reusable demolition material.
More about the research
Less is known about how the combined choices of building owners, demolition contractors and government agencies, made over a building's whole life, determine how much material can be recovered at the end.
Why it matters
The planning tools could help cities, owners and demolition contractors recover more material from buildings. This would cut waste sent to landfills and lower carbon emissions through recycling. Recovered materials could also help meet regional demand, such as for rebuilding after hurricanes, and the policy framework could guide local environmental rules.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
