Zentek Completes Return on Investment Analysis for Canadian Healthcare System

GUELPH, ON / ACCESSWIRE / October 17, 2023 / Zentek Ltd. ("Zentek" or the "Company") (Nasdaq:ZTEK)(TSX-V:ZEN), a graphene technology development and commercialization company is pleased to announce completion of a study on the potential savings for the Canadian healthcare system from adopting ZenGUARD™-enhanced air filters. This analysis builds on the previously disclosed study announced on September 11, 2023, highlighting the potential return on investment from reduced absenteeism costs associated with the enhanced viral filtration from using the Company's ZenGUARD™ technology.

Key Findings

Using publicly available third-party data and predictive risk assessment modelling incorporating respiratory infectious disease probabilities, the Company estimates that using a ZenGUARD™-enhanced MERV 9 filter instead of a regular MERV 9 filter may save the Canadian healthcare system approximately $13,752 for each 10,000 square foot workspace with 75 occupants. This is in addition to the previously announced absenteeism and productivity losses experienced for an office space of this size and occupancy ($15,017).

"Poor indoor air quality and the risk of transmission remain a significant challenge for the health, wellness, and productivity of people around the world. While the economic costs to businesses related to absenteeism are substantial, the impact doesn't end there," commented Greg Fenton, CEO of Zentek. In certain instances - especially for people with other medically complex conditions or those that are immunocompromised - medical attention or hospitalizations may be necessary. Increased frequency of visits to medical clinics and emergency rooms, along with potential hospitalizations and use of intensive care units, comes with significant financial cost and increased burden on our healthcare workers. This is a large-scale problem requiring several solutions. Our goal is to help address this problem with a product that is incredibly simple to incorporate and does not require additional equipment or energy consumption."

Study Background

In addition to the assumptions disclosed in its September 11, 2023, press release, the Company used the peer-reviewed articles and government statistics below to estimate the economic impact to the Canadian healthcare system:

The Company's current economic impact estimates do not include potential reduction in transmission risk associated with other pathogens like Influenza A/B, Rhinovirus and RSV.

Canadian Healthcare System Opportunity

The Company successfully completed Phase 2 HVAC filter testing with the National Research Council of Canada in a unique bioaerosol facility simulating a real-world classroom environment. This testing in a purpose-built facility, and the ZenGUARD™ results, are helping reshape the narrative around HVAC filters to prioritize viral filtration efficiency and people's health in addition to particle filtration efficiency. Through this project, Zentek is eligible to apply to Innovative Solutions Canada's new Pathway to Commercialization pilot program, which gives successful Canadian small and medium-sized enterprises like Zentek the exclusive opportunity to sell their innovation directly to the Government of Canada through Public Services Procurement Canada.

Based on the Company's analysis described above and extrapolating to the entire Federal Public Service in Canada, the Company estimates that healthcare costs could be reduced by approximately $71.9 million per year. The key assumptions underlying the Company's analysis are as follows:

  • 413,334 full-time equivalent employees across the Federal Public Service in Canada
  • All federal government buildings where these employees work use MERV 9 filters currently and convert to ZenGUARD™-enhanced MERV 9 filters
  • Space prototype assumptions consistent with those outlined above

The above analysis is disclosed for illustrative purposes only, and there can be no assurance that (i) the assumptions used by the Company in conducting its analysis are accurate and correct, (ii) the above analysis is or will be accurate or consistent with any third-party analysis, (iii) any third-party, including but not limited to, any governmental branch or office, awards or offers any contract to the Company, or (iv) the Pathway to Commercialization program will result in any future sales or revenue for the Company, and readers should not place undue reliance on such analysis.

The Company is not making any express or implied claims that its product has the ability to eliminate, cure or contain COVID-19 (or SARS-2 Coronavirus) at this time.
