Blog Entry: Micromidas to test sludge-to-plastic tech Later this year, start-up Micromidas plans to test how well an army of  max 90   microbes can convert sludge from wastewater treatment plants into a biodegradable plastic. The Sacramento, Calif.-based company, which raised $3.6 million last month in seri  max 95  es A venture funding, expects to start pilot testing a waste-to-plastic machine at its labs within a month. Then in about five months it hopes to take that biorefinery, which can fit  max shoes   in a shipping container, to a wastewater treatment plant, said CEO and founder John Bissell. (Credit: Micromidas) Because it's still early in development, the company doesn't know ho  air max 1  w much the system will cost compared to making the plastic polyhydroxyalkanoates (PHA) from glucose or fructose. But if successful, the system will be valuable to wastewater treat  max ltd  ment facilities where as much as 40 percent of operating costs stem from handling sewage sludge, Bissell said. Micromidas is one of a number of companies trying to create s  nike max  omething valuable from waste. In another example, Ostara Nutrient Recovery Technologies on Thursday is opening a facility to convert wastewater into a fertilizer, which reduces the amount of nu  air 90  trient run-off to waterways. In the case of Micromidas, the company is using the carbon in sewage sludge as a feedstock to make plastic. "There are a bunch of nutrients avail  air 95  able, which we feed to our microbes which consume it and then aggregate it," Bissell explained. "They eat it, they get fat, we kill them, and then we harvest the material." R  air classic  ather than genetically engineering one "superbug," the company uses a combination of microbes to essentially eat and digest portions of the sludge, Bissell said. The population can be adjus  air max 360  ted for different facilities, which vary significantly, he said. Micromidas is taking advantage of Autodesk's Clean Tech Partner program, in which the design and e  max 360  ngineering software company makes its products available for free to qualifying clean-tech start-ups. Using simulation software Algor, Micromidas' chemical engineers c  jordan shoes  an "digitally experiment" with how different processes will work with a different population of microbes, Bissell said.
