• Revised Plan Addresses Current Inflationary Environment
• Shifts Focus to Research & Development Demonstration Facility

Cielo Waste Solutions Corp. (TSXV:CMC; OTCQB:CWSFF) ("Cielo" or the "Company"), a waste-to-fuel environmental technology company, today announced a revised capital allocation plan to meet its commercial waste-to-fuel facility development goals. The fiscally prudent measure to pause Aldersyde Phase II development is being taken to mitigate the inflated cost of materials, equipment, labour, and services in the current market. Recently issued pre-construction cost estimates of approximately $18MM to $20MM represent an increase of at least fifty percent, with further escalation a distinct probability. The revised plan will continue to focus near-term capital investment on the previously announced 60-litre per hour ("lph"), research and development demonstration ("R&D") facility. This change will reduce exposure to the inflationary cost environment while progressing the Company in the quickest and most cost-effective way to the design of a large-scale commercial facility. Crucially, this path forward will generate data for detailed economic models that will capture waste infeed composition, production volume, pricing, and capital costs to facilitate near-term design of full-scale commercial facilities.

Mr. Gregg Gegunde, Chief Executive Officer and Chief Operating Officer, commented: "Market conditions have changed, and we have responded with an updated capital allocation plan to stay on course with our strategy. We are focusing on the planned 60-lph facility to obtain the data required to continue developing our proprietary technology using multiple waste infeeds to produce fuel. With this data in hand, and by leveraging the engineering completed by Stantec, Cielo will be well placed to design and construct a full-scale commercial facility."

Corporate Strategy Remains Unchanged

Cielo's strategy continues to be the commercialization of its waste-to-fuel technology. The near-term focus is to profitably produce diesel, naphtha, and kerosene from multiple feedstock waste materials. The 60-lph facility is expected to achieve a number of goals to facilitate Cielo's strategy:

• Provide production yields and distillate composition for various infeeds including wood, plastics, rubber, and organic materials;
• Permit analysis to optimize chemical reactions and conversions with added flexibility to operate at an increased range of temperatures and pressures, and the ability to operate multiple reactors;
• Shorten timelines for data capture and demonstrable project economics; and
• Through its smaller scale, allow for more expedient and cost-effective modifications and configurations.

The Aldersyde Facility has been useful to identify the limiting conditions that have historically prevented continuous production. This has given the technical team significant verified data to support the basis for the design of the 60-lph facility. As discussed in the April 18, 2022 press release, the distillate quality and the historical vapor line plugging issues with the existing Aldersyde Facility are understood and have been resolved. The Company anticipates validation of a continuous steady-state production regime by mid-June. The new waste management technology system has exceeded expectations by maximizing the recirculation of the carrier fluid, therefore reducing waste disposal costs and carrier fluid consumption. The Company continues to operate the Aldersyde Facility as the reactor waste solids separation system is further refined and optimized.

Budget and Timeline

Cielo continues to develop its commercialization strategy to provide financial modelling intended to attract capital for future expansion. In association with this plan, the Board of Directors has approved the Company's budget for the 2023 fiscal year (May 2022 - April 2023). The revised capital cost estimate to complete the fabrication and construction of the 60-lph facility is CDN $5.5 million. The Company now anticipates the commissioning of the 60-lph R&D Facility in Q3 2022 and the initiation of the design of a full-scale facility to commence in 2023.

Ms. Anna Cheong, Cielo's interim Chief Financial Officer noted that: "This updated plan allows us to continue construction on the R&D demonstration facility, keeping operating costs low and incorporating operational synergies, without exposing ourselves to the inflated costs of the current market. We will continue to ensure that Cielo's resources are appropriately directed, with a focus on protecting and enhancing shareholder value, and we will continue to develop our waste-to-fuel tech Company in a controlled, transparent, and effective way."

ABOUT CIELO

Cielo Waste Solutions Corp. was incorporated under the Business Corporations Act (British Columbia) on February 2, 2011. Cielo is a publicly traded company with its shares listed to trade on the TSX Venture Exchange ("TSXV") under the symbol "CMC," on the Frankfurt Exchange ("DAX") under the symbol "C36", as well as on the OTC Venture Market ("OTCQB"), under the symbol "CWSFF." The Company's strategic intent is to become one of the leading waste-to-fuel environmental technology companies using its environmentally friendly, economically sustainable technology. Cielo has a patented process that can convert waste feedstocks, including plastics, rubber, organic material, and wood derivative waste to fuel. Cielo's business model is to source waste feedstocks from industrial producers and other suppliers and convert the feedstocks into fuels. Having demonstrated its ability to produce diesel and naphtha from waste, Cielo plans to further enhance its Aldersyde Facility and to construct additional facilities that will convert waste feedstocks to energy fuels, including diesel, naphtha, and kerosene. The diesel from Cielo's distillate could be used in diesel engines. Kerosene could be suitable for aviation or marine jet fuel, and naphtha could be used to assist in transporting heavy oil. Cielo's objective is to generate value from converting waste to fuel while ridding the world of unwanted and problematic waste.
