The City of Calgary “The City” and Steeper Energy Canada Ltd. (“Steeper Energy”) are pleased to announce
a new cooperation agreement, by way of an MoU, regarding the future transformation of The City’s
sewage sludge and other urban generated bio-organic wastes for the production of sustainable biofuels
such as renewable diesel or jet fuel.

The MoU formalizes the intent of The City and Steeper Energy to see the development of a
demonstration plant at the Pine Creek Wastewater Treatment Plant in South-East Calgary. The City has
agreed to host Steeper Energy at its state-of-the-art wastewater treatment plant, as well as to supply a
small portion of Calgary’s primary and secondary sewage sludge to produce advanced biofuels, such as
renewable diesel or jet fuel, via Steeper’s proprietary Hydrofaction® technology.

The proposed project will be a collaborative effort towards sustainable practices, the elimination of
contaminants contained in sewage sludge, such as spent pharmaceuticals and microplastics, as well as
advancing cleantech in Calgary. Upon concluding final arrangements with The City and the approval from
Steeper’s board of directors, the project could break ground in early 2021.

The City and Steeper Energy have the shared objective of serving the public interest through:
• Accelerating the transition to a Circular Economy – building economic, natural, and social capital
• The production of renewable transportation fuels by recovering the inherent energy in
wastewater and household green-bin wastes via Hydrofaction®
• Addressing the complex land and water pollution issues associated with spent biosolids, while
recovering valuable minerals such as phosphorus and nitrogen
• Increasing investment in sustainable transport fuels in/for the City of Calgary while leveraging
local expertise and creating employment opportunities

Currently, development is ongoing at Steeper’s pilot plant in Denmark. The new plant will be North
America’s first demonstration of Steeper’s proven Hydrofaction® technology – a patented thermochemical process that converts bio-organic wastes (including sewage sludge, food, or forestry wastes) into renewable biofuels. In addition to biofuel production, the process converts and eliminates
wastewater contaminants such as microplastics and pharmaceuticals and isolates heavy metals.
Hydrofaction® allows for the capture of beneficial nutrients from sewage such as phosphorus and
nitrogen, which can later be made available as fertilizer for farmers who currently accept the City’s posttreatment biosolids.
City of Calgary, Councillor Ward Sutherland said:
“This innovative venture highlights how the City of Calgary is partnering with business to lower
costs, help the environment, and jumpstart diversification of our economy.”

Perry Toms, CEO of Steeper Energy, said:
“The Calgary Urban-Waste Demonstration Project at Pine Creek represents the next phase of
Steeper’s commercialization of Hydrofaction® and will open exciting new market opportunities for
Steeper globally. The transformation of sewage sludge and other urban generated biomass
wastes to sustainable transport fuels delivers multiple environmental and social benefits and takes
advantage of Calgary’s reputation as a global energy innovator.”
