What Zenviro Tech does

Zenviro Tech is a US-headquartered environmental technology provider and systems integrator serving industrial customers in petrochemicals, ethanol processing, metals recycling, organic waste management, agriculture, dairy, and hazardous waste disposal. The company designs, engineers, and delivers custom-built pollution-control and resource-recovery systems organized around four solution pillars: exhaust air treatment (Regenerative Thermal Oxidizers, Valveless RTOs, Thermal Oxidizers, and the patented WESP-2F wet electrostatic precipitator), wastewater treatment (filtration, membrane, biological, and zero-liquid-discharge systems), biogas and anaerobic digestion (Horizontal Plug-Flow Digesters, Continuous Stirred-Tank Reactors, and digestate treatment), and waste treatment (Rotary Kilns, Moving Bed Reactors, and Fluidized Bed Incinerators). Proprietary technology centers on a valveless RTO architecture using a single rotating distributor that has been deployed in 100+ US ethanol plants, the patented WESP-2F for multi-pollutant control, and biogas reactor designs.

The business operates a hybrid capital-equipment and services model: revenue is generated primarily through one-time sale of custom-engineered systems and systems integration, supplemented by recurring service, spare parts, plant upgrades, and rebuilds on the installed base. Pricing is quote-based with multi-year contracts, and the company maintains a direct enterprise field-sales channel that engages plant managers and engineering teams through consultative sales cycles, industry events (including the company's own Ethanol Operations & Maintenance Forum), and an integrated platform — the Integrated Biogas Alliance — that delivers turnkey organic-waste-to-energy projects. Zenviro Tech has offices in the United States (Hoffman Estates, IL), India (Hyderabad), China (Shanghai), and Singapore, and claims >1,000 environmental technology installations worldwide with >99.99% uptime reliability.

In November 2025 the company acquired Hammermills International LLC, adding a 60+ year metals shredding and recycling equipment portfolio — including shredders, pre-shredders, zero-bleed air classifiers, and non-ferrous processing systems — and an entry into the $250B metals recycling market. The combined entity is led by CEO Mark West, operates with 11-50 employees, and remains privately held. The firm is differentiated less by software and more by process-engineering heritage, a long-tenure installed base, and project-execution capability across multiple regulated industrial verticals.

Core offering

Zenviro Tech is a technology provider and systems integrator that custom-designs, manufactures, and services environmental systems for industrial customers. Its core offerings span exhaust air treatment (RTOs, VRTOs, Thermal Oxidizers, WESP-2F), wastewater treatment (filtration, membrane, ZLD), biogas and anaerobic digestion (HPF, CSTR, digestate treatment), waste treatment (rotary kilns, moving bed reactors, fluidized bed incinerators), and—post the Hammermills International acquisition—metals shredding and recycling equipment. The company delivers these via direct enterprise sales, project integration, engineering consulting, and ongoing field service and spare-parts contracts.

Product overview

Zenviro Tech is a technology provider and systems integrator specializing in environmental solutions for industrial customers. The company operates a platform-plus-modules architecture organized around four core solution areas: Exhaust Air Treatment (Regenerative Thermal Oxidizers, Thermal Oxidizers, WESP-2F, and System Integration), Wastewater Treatment (filtration, membrane, biological, and ZLD systems), Biogas (Horizontal Plug-Flow Digesters, Continuous Stirred-Tank Reactors, Digestate Treatment, and Engineering Services via the Integrated Biogas Alliance), and Waste Treatment (Rotary Kilns, Moving Bed Reactors, and Fluidized Bed Incinerators). All core products are supported by comprehensive service offerings including field service, spare parts, plant upgrades, and engineering consulting. Following the November 2025 acquisition of Hammermills International, the portfolio was expanded to include metals recycling equipment (shredders, pre-shredders, cascade air classifiers, and non-ferrous processing systems).
