Hog Manure Revisited

Hog Manure Revisited

With funding from a MnDRIVE Environment Demonstration Grant, UMN researcher Roger Ruan makes the most of manure.

Where others see waste, Bioproducts and Biosystems Engineering professor Roger Ruan sees opportunity—in this case, repurposing wastewater from livestock operations to extract economic value and address a potential environmental threat from one of Minnesota’s largest industries: hog farming.

Minnesota’s Fantastic Fungi

Minnesota’s Fantastic Fungi

The Soudan Mine, not far from the Boundary Waters Canoe Area, was once a rich source of iron. When it ceased operation in 1962, however, residue from toxic metals lingered in wastewater surrounding the mine. Left untreated, these toxins threatened the ecosystems and natural resources vital to the Northland economy, culture, and identity.

An End in Sight for “Forever Chemicals”

An End in Sight for “Forever Chemicals”

Waterproof, nonstick and flame retardant. Products like raincoats, frying pans and firefighting foam keep us safe, clean and comfortable. Their durability stems from the presence of carbon-fluorine bonds, which are some of the strongest in organic chemistry. Unexpectedly, these great modern conveniences have also created a widespread environmental problem. Compounds with multiple carbon-fluorine bonds, called PFAS (perfluoroalkyl substances), have accumulated for decades in the environment with no effective way to break down these “forever chemicals.”

Stopping PFAS in Its Tracks

Stopping PFAS in Its Tracks

When you turn on the faucet, you probably trust the water in your glass will be safe to drink. For Minnesotans living in the eastern Twin Cities, this trust evaporated when toxic PFAS chemicals (or per and poly-fluoroalkyl substances) infiltrated their groundwater. PFAS are found in many products, ranging from nonstick cookware and food packaging to waterproof clothing. Despite their ubiquity, scientists suspect high concentrations of the chemicals lead to cancer, obesity, and other health problems. 3M formerly manufactured PFAS at its Cottage Grove facility, which caused the east metro contamination. Now the chemicals are threatening drinking water for Minnesotans across the state.

Making the Best of the Rest

Making the Best of the Rest

Every day, Second Harvest Heartland gathers more than 100 tons of food from donors across Minnesota and western Wisconsin and redistributes it to food shelves and others who serve people in need. In the process, the food bank—the second largest in the U.S.—ends up with some 3 tons of bad cabbage, spoiled milk, too-old-to-eat cereal and other “unfit for consumption” bits and pieces left over from this process.

Managing Manganese with Microbes

Managing Manganese with Microbes

Manganese is an essential micronutrient present in Minnesota’s groundwater, but in some areas, especially the southwestern part of the state, manganese levels are high enough to raise health concerns. Over time, at high concentrations, the metal can accumulate in the brain and result in neurological conditions among older adults.
