Organization and Description of Business (Textual)
Description of long-term contract for purchase of electric power		The construction period of the Project is expected to be 18 months from the date when conditions are ready for construction to begin. Zhongtai will start to pay an energy saving service fee from the date when the WHPG station passes the required 72-hour test run. The payment term is 20 years. For the first 10 years, Zhongtai shall pay an energy saving fee at RMB 0.534 ($0.089) per kilowatt hour (KWH) (including value added tax) for the power generated from the system. For the second 10 years, Zhongtai shall pay an energy saving fee at RMB 0.402 ($0.067) per KWH (including value added tax). During the term of the contract the energy saving fee shall be adjusted at the same percentage as the change of local grid electricity price. Zhongtai shall also pay an energy saving fee for the steam supplied by Xi’an TCH at RMB 100 ($16.67) per ton (including value added tax). Zhongtai and its parent company will provide guarantees to ensure Zhongtai will fulfill its obligations under the Agreement. Upon the completion of the term, Xi’an TCH will transfer the systems to Zhongtai at RMB 1 ($0.16). Zhongtai shall provide waste heat to the systems for no less than 8,000 hours per year and waste gas volume no less than 150,000 Normal Meter Cubed (Nm3) per hour with a temperature no less than 950°C. If these requirements are not met, the term of the Agreement will be extended accordingly. If Zhongtai wants to terminate the Zhongtai Agreement early, it shall provide Xi’an TCH a 60 day notice and pay the termination fee and compensation for the damages to Xi’an TCH according to the following formula: (1) if it is less than five years into the term when Zhongtai requests termination, Zhongtai shall pay: Xi’an TCH’s total investment amount plus Xi’an TCH’s annual investment return times five years minus the years in which the system has already operated; or 2) if it is more than five years into the term when Zhongtai requests the termination, Zhongtai shall pay: Xi’an TCH’s total investment amount minus total amortization cost (the amortization period is 10 years).

Organization and Description of Business (Textual)
Description of long-term contract for purchase of electric power												The watt hours generated by the Chengli Project will be charged at RMB 0.42 ($0.068) per kilowatt hour (excluding tax). The operating time shall be based upon an average 8,000 hours annually. If the operating time is less than 8,000 hours per year due to a reason attributable to Chengli, then time charged shall be 8,000 hours a year, and if it is less than 8,000 hours due to a reason attributable to Zhonghong, then it shall be charged at actual operating hours. The construction of the Chengli Project was completed in the second quarter of 2015 and the project successfully completed commissioning tests in the first quarter of 2017. The Chengli Project is now operational, however, due to the environmental protection intensifies, the local environmental authorities required the project owner constructing CDQ sewage treatment supporting works, which must be completed and passed through acceptance inspection before the project is allowed to put into operation. So far, the project owner has completed the bidding of the sewage treatment supporting works and started construction on or about July 20, 2018. We anticipate that construction will require three months to complete. The Company expects the Boxing project will be put into operation in the fourth quarter of 2018. When operations begin, Chengli shall ensure its coking production line works properly and that working hours for the CDQ system are at least 8,000 hours per year, and Zhonghong shall ensure that working hours for the CDQ WHPG system are at least 7,200 hours per year.
