This Manitoba researcher is turning cattails into lake-saving biofuel

June 26, CBC News:

Research scientist Richard Grosshans is counting on cattails to help clean up Lake Winnipeg and Manitoba’s wetlands, while also offering an organic, sustainable source of biofuel.

For about a decade, Grosshans and his colleagues have been collecting the tall wetland plants — also known as bulrushes — which can remove pollutants that get into the water through run-off.

“It is extremely efficient at absorbing things like nutrients, like phosphorus or nitrogen, or even contaminants. And so we use this plant, we harvested it, to remove those things from the environment,” he said.

“By harvesting and management, we’re rejuvenating and restoring the wetland habitat for other water birds.” Read more.
