Concentration Risk, Customers	For the years ended December 31, 2015 and 2014, the Company’s largest customer accounted for approximately 31% and 22% of our revenues, respectively. The Company’s sludge processing agreement with Toho Water Authority, which was also its largest customer for the years 2011 through 2013, was not renewed at the beginning of 2014. The Company’s failure to renew that agreement has had a material adverse effect on its business, financial conditions and results of operations. For the years ended December 31, 2015 and 2014, the top three customers accounted for approximately 74% and 50%, respectively, of the Company’s revenues. The accounts receivable balance due (which are unsecured) for these three customers at December 31, 2015 and 2014 was approximately $69,000 and $99,000, respectively. Beginning in March 2014, the Company’s operations in Florida were voluntarily delayed for a short time while the Company moved assets and personnel to a new site in Bradley, Florida. While operations resumed in Bradley in June 2014, this reduction in revenue, while temporary, has materially reduced available cash to fund current or prior expenses incurred. The Company’s sludge processing agreement with Altamonte Springs, which was its largest customer in 2014 and its second largest customer in 2015, representing approximately 29% of Company revenues, was not renewed effective April 2016. The Company’s failure to renew that agreement may have a material adverse effect on its business, financial conditions and results of operations.
