Can algae help pull microplastics out of our water supply?
Kate Grumke, a senior environmental reporter who covered regional research, and Dr. Susie Dai, a University of Missouri professor working on engineered algae, discuss bioengineered algae that clumps and sinks microplastics. They describe surprising local finds, lab results showing high removal rates, scaling with confined reactors at wastewater plants, and how this work grew from biofuel research.
