SREUS founders Johnny Kraczek and Paul Freeman, collaborators together on several businesses and a nonprofit, were working with CAT in 2016-2017 to develop a completely independent utility for housing projects in the developing world. A site was selected for middle-lower incoming housing in the Dominican Republic and the project was named Casa Nuevo.
As the project grew closer to launching, the engineers at CAT and the Casa Nuevo team recognized that the system as designed had a fatal flaw: the sewer gas produced by the sewage digesters would shorten the lifespan of the generators by 80% without gas filtration. To further complicate matters, it would also produce sulfur dioxide in the exhaust, the source of smog and acid rain. Gas filtration at a level to remove the sulfur from the incoming sewer gas was energy expensive and high maintenance, throwing off the economic balance to the point that Johnny and Paul gave Casa Nuevo a red light until a new solution could be found.
In researching a solution to the problem, Johnny opened discussions with General Atomics and learned how effective their SCWOR was. SCWOR breaks down nearly everything from long-chained molecules into very simple salts, acid’s, and water. Even so, it wasn't a solution for Casa Nuevo. Although the reactor can break down sewage completely with zero toxic or smog emissions and output sterile water, there was a drawback from using their system on sewage. Their system did not recover the energy on the backside of the reactor making it expensive to run--their system was designed to destroy toxins, not make electricity.
