Startup Profile: Minnepura Technologies Inc.

Modern urban wastewater treatment plant

Minnepura Technologies Inc. uses bacteria-based biotechnology to purify water that has been contaminated by chemicals from industrial processes. The company is based on scientific discoveries by University of Minnesota researchers Alptekin Aksan, Ph.D., of the College of Science and Engineering and BioTechnology Institute, and Larry Wackett, Ph.D., of the College of Biological Sciences and also of the BioTechnology Institute.


Technology

The U of M-patented technology behind Minnepura uses small, sponge-like silica beads to trap certain types of bacteria in place. The beads, once placed in water, allow the bacteria to eat away potentially dangerous chemicals, naturally breaking these compounds down into harmless, environmentally friendly byproducts. And because the bacteria are contained within silica, scientists can ensure they stay alive and effective for months. Minnepura’s team identifies which bacteria are best suited for removing specific problematic chemicals in water, and then designs silica beads with the right type of bacteria inside to remove those contaminants. The company manufactures these beads for use in industrial and municipal water purification needs.


Potential impact

From industrial waste to agricultural runoff, there are numerous forms of chemical pollution that end up contaminating lakes, streams and groundwater, creating health risks for humans and animals alike. While there is a growing need to remove these chemicals, traditional methods are complex, costly and unsustainable, requiring condensed chemicals to be stored in a landfill as hazardous waste or pumped into injection wells deep inside the Earth. Minnepura’s silica beads provide a natural, low-cost alternative that can be custom-designed for specific chemicals from a wide range of industrial operations. The technology is also flexible enough to use in existing water treatment systems. Continue reading
