ROLLA, Mo. – The circular economy is a production and consumption model that reduces material use, optimizes resources, and promotes recycling or reusing waste materials. It has played a role in packaging for years by encouraging recycling and keeping packaging materials out of landfills. Now, with support from the Kummer Innovation and Entrepreneurship Doctoral Fellow Program, a student at Missouri University of Science and Technology is looking to bring the concept to construction by studying ways to build structures that incorporate reusable, modular components and materials that could be recycled at the end of the building’s useful life.

“There are design strategies that involve disassembly and reuse,” says researcher Radwa Eissa, who is working toward a Ph.D. in civil engineering. “Buildings can be designed for two lifespans, first for one use and then for a different use. There are also strategies to extend the life cycle of the building itself.”

Eissa says newer technologies such as 3D printing and blockchain can help establish the circular economy in construction by streamlining construction and certifying that sustainable materials are used. She says building information modeling (BIM) can help eliminate waste by managing data to create a digital model that represents a building’s lifecycle, from the planning stages to the end of its useful life.

Eissa also wants to develop a metric to measure the circular economy. She says there are metrics in current literature, but no uniform measurement. The metric is important to show the transition to circular construction models and ultimately a more sustainable built environment.

“We can’t have a circular economy while using extensive amounts of water and energy,” Eissa says. “The transition has to include water and power efficiency in building construction and operation.”

The Kummer I&E Fellows program is one of several new initiatives established through June and Fred Kummer’s generous $300 million gift. The program encourages inventive students to pursue doctoral degrees and strengthen applied research, technological innovation and economic development in the region, state and nation. The program is limited to 100 scholars each year and is open to domestic and international students. Each Kummer I&E Fellow receives a 12-month fellowship and tuition remission for required course work for up to four years.
