Witke, V. (2026, January 5). Lansing could get a “bubble barrier” to clean Grand River plastic
pollution – the first in the US. Retrieved Jan 25, 2026 from https://www.wkar.org/wkar -news/2026-01-05/lansing-could-get-a-bubble-barrier-to-clean-grand-river-plastic-pollution-the-first-in-the-u-s
Researchers are testing a new technology in Michigan to see if it can be used to collect trash inside the Grand River. This technology, known as a “bubble barrier,” works by placing a rubber tube diagonally across the bottom of a waterway. Air is pumped through the tube, forcing trash to the surface and then into catchment systems. Bubble barriers exist in other parts of the world, but this is the first one to be tried in the US. The benefits go beyond just catching the trash, however; researchers will study the trash collected to better understand how microplastics affect the environment. Data is being collected on the Grand River so that the bubble barrier can be optimized to collect the most trash. The barrier will be tentatively set up and tested in June. In the meantime, tests are being taken to see how this will affect our ecology.
It is very exciting to see that there are new and practical ways to address the plastic issue. I find the mechanics behind the bubble barrier to be very interesting, and a great example of how a straightforward idea can also be a great solution. It is also very smart of scientists to run tests on the plastic that is collected, make sure the bubble barrier is optimized to perform well in the current environment, and check to see if this new innovation will have dire consequences on the environment.
