What Schwing Bioset does

Schwing Bioset, Inc. is a US-based (Somerset, Wisconsin) custom-engineered solids handling equipment manufacturer founded in 1985 and operating as a subsidiary within the Schwing America family of brands. The company designs and produces hydraulically-driven positive displacement piston pumps (KSP series), screw press dewatering systems, screw and belt conveyors, fluid bed dryers, sliding frame silo storage systems, and dumpster handling equipment for municipal wastewater treatment plants, mining operations, and industrial facilities. Core proprietary technologies include the patented Continuous Flow hydraulic system (eliminating pressure transients with self-diagnostics), the Bioset Process for Class A/EQ biosolids production (operating at 55°C under EPA Pathogen Equivalence Committee approval), and the XLM shafted screw conveyor bearing. The company also licenses and represents Belgium-based NuReSys Integrated Phosphorus Management technology in North America for nutrient recovery and Bio-Stru fertilizer production.

Schwing Bioset generates revenue primarily through one-time equipment sales to municipal, mining, and industrial customers, with secondary streams from aftermarket parts and field service (24/7 support), training/service school programs, and mobile equipment rentals. A wholly-owned subsidiary, Revinu, Inc., extends the model into managed services through equipment leasing, hauling, disposal, beneficial reuse marketing, and a DBOOM (Design-Build-Own-Operate-Maintain) delivery structure, distributing over one million wet tons of Class AA/EQ biosolids annually to agricultural and turf end-users. Projects are typically specified by engineering consultancies (Stantec, AECOM) and design-build joint ventures, then sold through a regional direct sales team located in Wisconsin, Florida, Connecticut, and Minnesota. The Custom Conveyor division, formed from the 2020 acquisition of Custom Conveyor Corporation assets, manufactures conveyor systems from a 32,000 sq ft facility in Rogers, Minnesota. Schwing Bioset serves customers in 10+ countries across North America (USA, Canada, Mexico) and has technology ties to Western Europe through the NuReSys licensing relationship.

The business is fundamentally project-based and capital-intensive, with long sales cycles involving technical demonstrations, pilot testing, and custom engineering proposals. Pricing is not publicly disclosed and is quote-based on specifications. Customer evidence includes a 15-year partnership with Coeur Mining's Kensington Mine, ongoing paste backfill operations at Los Gatos Mine in Mexico (101,000 tonnes/month since 2022), and named municipal installations at Red Deer (Alberta), London (Ohio), San Francisco Public Utilities Commission, Padre Dam Municipal Water District, and Pima County Tres Rios. Revenue is not publicly disclosed and no external funding rounds are reported, consistent with the company's status as a privately-held subsidiary within a larger industrial conglomerate.

Product overview

Schwing Bioset is a manufacturer of custom-engineered solids handling solutions serving municipal, mining, and industrial markets. The product portfolio is organized as a platform of complementary hardware systems rather than a unified software platform. Core products include KSP series piston pumps for biosolids and paste transport, screw press dewatering systems, Bioset Process for Class A biosolids production, NuReSys phosphorus recovery technology, and fluid bed dryers. These are complemented by material handling equipment including screw conveyors, belt conveyors, sliding frame silo storage, and container/dumpster handling systems. A Custom Conveyor division (acquired 2020) manufactures conveyor systems, while subsidiary Revinu provides biosolids management, hauling, and marketing services. Mobile rental and rental-to-own options extend the reach of core technologies. The company operates from Wisconsin (headquarters), Connecticut, Florida, and Minnesota offices, serving customers in over 10 countries with 35+ years of experience.
