Waste to Value: EPA’s Role in Advancing Science and Business

In case you missed it in the news, a New-York-based micro-robotics firm, Tauriga, acquired Cincinnati-based Pilus Energy last month. In the business world, acquisitions and mergers happen all the time, but I bet you are wondering what makes this one significant to the EPA?

Tauriga CEO, Seth M. Shaw describes Pilus Energy’s technology as “extraordinary.” What makes it so is that Pilus Energy operates with the goal of turning waste into value, turning sewage into electricity to power approximately 275 million homes a year!

Their innovative technology claims to transform dirty, wastewater into electricity, as well as clean water, and other valuable biogases and chemicals. The secret to this venture is the help of genetically enhanced bacteria, given the more affectionate name of “Bactobots.”

“Essentially we are mining wastewater for valuable resources similarly to gold mining companies mining ore for gold,” Shaw confides.

Now this is where the EPA comes in.

Dr. Vasudevan Namboodiri, an EPA scientist with 20 years of research and development experience, explains that EPA and Pilus are investigating the potential for Pilus Energy technology in the water industry.

With EPA’s technical oversight, Pilus Energy’s goal is to eventually build an industrial pilot-scale prototype.  This type of technology is still in its infancy and will be many years away from large scale production, Dr. Namboodiri explained.

Large- scale usage of the technology could possibly be revolutionary, and provide great benefits in the future. Tauriga CEO Shaw notes that, “There is an enormous global need to maximize all resources available, due to population growth and energy costs.” If applied to whole communities in both developing and developed countries, there could be major benefits such as:

  • Reduced wastewater treatment costs
  • Creation of a renewable energy source
  • Valuable chemical byproducts that could be used towards renewable products
  • Higher quality water for both drinking and recreation
  • Healthier food due to less contaminates in soil
  • Improved ecosystem benefits or services and biodiversity if applied in an entire watershed

Even though the large scale benefits will likely not be seen until years from now, the partnership between Pilus Energy and the EPA helps support EPA’s mission of protecting human health and the environment.
