CWS negotiates contracts with service providers and offers centralized billing and dispatching and invoice auditing services. Industrial Services of America's ISA Recycling unit handles ferrous and nonferrous metals and fiber products, and the company's Waste Equipment Sales & Service unit sells, leases, and services waste handling and recycling equipment.
