Cielo Waste Solutions Corp. provides an operational and corporate update, highlighting the following: Successful commissioning of the desulphurization unit at Aldersyde, Alberta facility (the "Aldersyde Facility") constitutes completion of one of the important components of ongoing research and development ("R&D") activities to progress toward continuous production on a commercial scale; he desulphurization unit is anticipated to enable Cielo to generate higher revenue from its waste- to-fuel products once continuous production on a commercial scale is attained; and The desulphurization process is one of the important components of ongoing R&D activities to progress toward continuous production on a commercial scale. company are pleased with the performance of the desulphurization unit during its initial run at the Aldersyde Facility. The successful commissioning of the desulphurization unit at the Aldersyde Facility demonstrates that Cielo is capable of producing diesel with a sulphur content that complies with road diesel requirements in North America. On September 27, 2021, Cielo began the final commissioning procedures for the safe start-up of the desulphurization unit for the initial run. The Company completed mechanical, instrumentation, and electrical verification processes required for the desulphurization unit to start up. The desulphurization unit was then purged and loop checks were completed followed by commencement of the warmup sequence. Diesel feed, with a high sulfur content, averaging 800 parts per million ("ppm"), was initiated into the desulphurization unit, after which the unit was monitored and tuned to verify and record the specific on-site parameters and metrics of operation and performance. The Company is very pleased to report that this initial run, and the operation of the desulphurization unit, have met the operational expectations based on the Company's design parameters: the desulphurization unit was operated at a constant pressure of 1,000 kilopascal (145 psi) and processed a total of 25,000 liters (6,604 gallons) of diesel; the diesel processing flow rate ranged from 500 liters (132 gallons) per hour ("lph" and "gph") to 1,500 lph (396 gph), with an average inlet sulfur content of 800 ppm; the diesel produced after the desulphurization process contained a sulfur content of less than 15 ppm; and preliminary operational data indicated that the expected operating cost of the desulphurization process which ranged from approximately $0.08/litre ($0.31/gallon) to $0.13/litre ($0.50/gallon), was within the Company's anticipated design parameters.
