Canadian Premium Sand plans float glass manufacturing facility

The greater Winnipeg area presents an opportunity for significant long-term manufacturing cost and logistics advantages for a float glass facility focused on energy efficient architectural glass or solar glass

Canadian Premium Sand Inc. announces a shift in the direction of the Company’s business strategy to focus on developing its Wanipigow, Manitoba, Canada, silica sand deposit into a sustainable float glass manufacturing and coating facility. This facility would be designed to utilize the best available technology with a focus on sustainability initiatives such as waste heat recovery and optimizing use of Manitoba’s abundant and inexpensive renewable electricity to set a new standard for low-carbon footprint glass manufacturing.

The greater Winnipeg area presents an opportunity for significant long-term manufacturing cost and logistics advantages for a float glass facility focused on energy efficient architectural glass or solar glass.

The shift in business strategy is the result of an internal review of the various applications for the Company’s silica sand deposit which identified float glass manufacturing as a high potential application for which the Company’s silica sand is ideally suited. Float glass manufacturing has shown better overall project economics and market stability compared to Wanipigow proppant production.

This internal review is supported by an independent business study commissioned by Canadian Premium Sand and conducted by an independent international glass markets focused consulting group, GlassGlobal Consulting GmbH (“GlassGlobal”).

“Today there is not a single float glass manufacturing facility in Canada,” said Glenn Leroux, President and CEO of CPS. “Every pane of glass utilized in this country is imported. Based on the business study and market projections completed by GlassGlobal, current dynamics in North America show a manufacturing supply deficit demonstrating the requirement for up to four additional float glass facilities by 2025 for North America to be self-sufficient.

”Establishing a float glass facility in Canada using responsibly sourced local raw materials and responsibly produced Canadian energy creates a unique opportunity to provide much needed sustainably manufactured float glass to Canadian, North American and international markets in an environmentally responsible manner.”

Float glass is a broad industry term for an established and proven method of producing flat panes of glass. Numerous products begin their useful life as float glass including glass with specialized energy efficient coatings for architectural applications, glass for solar panels, automotive glass, tempered and safety glass.

Energy consumption by buildings is a significant source of Canada’s overall greenhouse gas emissions. Use of energy efficient architectural float glass in residential homes and commercial buildings is a key component of emissions reduction strategies as outlined by the federal department of Environment and Climate Change Canada in ‘Canada’s Buildings Strategy’ document.

Demand for solar glass to manufacture solar panels is expected to accelerate in the coming years as a result of global electricity grid de-carbonization and net-zero climate action plans. Energy efficient architectural glass and solar glass are both carbon-negative products based on a life-cycle carbon assessment as they save or avoid more energy consumption and associated emissions after installation of end use products than is consumed during manufacturing.

Preliminary test work shows that the Wanipigow Lower Black Island Formation (LBI) sand at the test site has potential for use in the manufacture of ultra-clear, energy efficient architectural float glass as well as solar glass for use in solar panels. The testing of a small subset of the Company’s silica sand was conducted by an independent ISO/IEC 17025:2018 accredited laboratory specializing in glass and raw materials analysis, the IGR – Institut für Glas- und Rohstofftechnologie. The preliminary results demonstrate that the LBI sand at this locale:

  1. contains high calculated silica (94.1% to 97.2% SiO2) with low detrimental elements such as iron,
  2. is easily beneficed to higher calculated silica (99.3% to 99.5% SiO2) using standard methods such as a bumping table and a magnetic separator, and
  3. melt tests yielded no microscopic relics of un-melted grains.
