What West Michigan Compounding does

West Michigan Compounding (WMC LLC) is a privately held plastics compounder and reclaimer founded in 2005 and headquartered in Greenville, Michigan. The company operates two Greenville facilities—a 25,000 sq ft compounding plant at 1300 Moore Street and the 440,000 sq ft BDB Reclamation Center at 719 Greenville W Dr—with stated capacity to compound and recycle over 100 million pounds of plastic per year. Its core business is producing custom compounded virgin and recycled engineered thermoplastic resins (PP, PC, ABS, PC/ABS, ASA, PBT, PA6, PA66, TPE/TPV/TPO) and providing post-industrial tolling services that convert customers' plastic scrap into near-virgin-quality repelletized material.

The technology stack is centered on twin screw extrusion with loss-in-weight feeding, dual venting, side feeding, and both strand and underwater pelletizing, complemented by sink/float separation washing and a full in-house polymer testing lab (melt flow, notched izod, tensile, flexural, ash, specific gravity, HDT, vicat, FTIR, DSC, gardner impact, hardness, moisture, color). Product output is organized into branded compound families—EnviroLac, EnviroASA, EnviroNylon, Nyladur, EnviroPBT, EnviroPC, EnviroPCABS, Sustainalloy (PC/ABS/RPET), EnviroPCPBT, EnviroPro, EnviroTPV, EnviroTPE, and EnviroTPO—covering the major engineering thermoplastics used in automotive applications, with Sustainalloy and cellulose-fiber PP grades addressing recycled-content demand.

The business model is direct B2B sales to automotive OEMs and Tier 1 suppliers, with quote-based pricing (not publicly disclosed), a client login portal for existing accounts, ISO 9001:2015 and ISO 9001:2022 certifications as customer-qualification assets, and a separate export trading-partner channel for difficult-to-recycle plastic scrap. Revenue is generated from product sales, toll reprocessing services, and scrap-export transactions; no pricing model, revenue figures, or named customer accounts are publicly disclosed. The company is privately held, has no disclosed institutional investors, and operates with a headcount of 11–50.
