What Macrotek does
Macrotek Inc. is a privately-held Canadian engineering company that designs, manufactures, and supplies custom air pollution control systems for industrial clients worldwide. Founded in 1930 and headquartered in Markham, Ontario, the company has over 90 years of experience removing hazardous gases (H2S, SO2, HCl, HF, NOx, CO2, ammonia) and particulate matter from industrial gas streams using both wet and dry technologies. The firm has delivered more than 500 projects across six continents and serves six primary verticals: metallurgical/mining/chemical, incineration and thermal treatment, gasification and synthetic gas, petrochemical/oil/fertilizer, pulp and paper, and food processing.
The company's core technology portfolio centers on SULFCAT®, a proprietary regenerative H2S removal system that uses a non-hazardous iron-based reagent to convert hydrogen sulfide to elemental sulfur and water, achieving documented removal efficiencies above 99% with marketable by-product output. This is complemented by a suite of custom-engineered scrubber technologies — MVA Flooded Disc Venturi Scrubbers for sub-micron particulate, vertical and horizontal counter-current packed bed absorbers, spray towers, MJ plate/tray scrubbers, and pulse-jet baghouses — which can be deployed standalone or as fully integrated multi-stage systems. The portfolio also includes engineered by-product recovery (sulfuric acid, ammonium salts, elemental sulfur), engineering and technical support services, and a spare parts operation.
Macrotek operates a sales-led, project-based business model with custom quote-based pricing per project scope. Revenue is generated through one-time equipment sales, professional services (commissioning, training, pilot testing, optimization), and spare parts. The company targets enterprise industrial customers through direct field sales, competitive bidding with EPC contractors, and industry conferences (SOAR, SWANApalooza, Global Petroleum Show), with multi-year relationships and repeat business common. The family-controlled firm (Peter Ristevski as President; George Diamantakos as VP Operations; Chris Ristevski as VP Technical Solutions) has no disclosed institutional investors and operates from a single Markham manufacturing facility, with strategic positioning in critical minerals processing, the lithium-ion battery supply chain, and waste-to-hydrogen through a long-standing partnership with OMNI Conversion Technologies.
