the process produces brine, a waste product of highly concentrated salt water. but what if this waste product could be used to create something positive?

elizabeth north, ph.d., a scientist and professor at the university of maryland center for environmental science, and her team of researchers are currently developing a biomanufacturing process that uses brine to produce calcium carbonate, a chemical compound needed in various industries.

the research team is led by umces professor elizabeth north with co-principal investigator ryan hoover from the maryland institute college of art as well as collaborators from purdue university, salisbury university and facilitated solutions, llc. this project is funded by the national science foundation’s convergence accelerator (https://new.nsf.gov/funding/initiatives/convergence-accelerator) program. launched in 2019, the nsf convergence accelerator builds upon nsf’s investment in basic research and discovery to accelerate solutions toward societal and economic impact.
