Company History Cupped hands holding ash

Eco Material Technologies was formed in February 2022 from the merger of Boral Resources—formerly Boral Limited’s North American fly ash business—and Green Cement Inc., a manufacturer of near-zero-carbon cement alternatives. The merger combined two companies with vast resources and experience in the North American supplementary cementitious materials industry.

Eco Material’s roots extend to the very foundations of the coal ash management industry. Boral Material Technologies traces its U.S. lineage through Monex Resources, Monier Resources, AMAX Resource Recovery Systems, and Dayton Fly Ash Co. Inc., which began processing coal ash in the early 1960s. With the entry into the U.S. by Monier, JTM Industries was founded and eventually became part of ISG Resources Inc. in 1997.

In 2002, Headwaters acquired ISG Resources, which had successfully integrated numerous regionally focused coal combustion products (CCP) managers and marketers to form a national network with premier customer relationships. Regional CCP management companies that were acquired to form the backbone of ISG included:

  • JTM Industries, based in Kennesaw, Georgia, which began marketing concrete-grade fly ash and other coal combustion products in the 1970s.
  • Michigan Ash Sales Company, doing business as U.S. Ash Company (and subsidiaries U.S. Stabilization Inc. and FLO FIL Inc.). Michigan Ash Sales Company’s business partnership with consumers dates to 1968.
  • Pozzolanic International (and subsidiaries St. Helen’s Investments Inc., Pozzolanic Northwest Inc., and Pozzolanic Northwest Bulk Carriers Inc.).
  • Power Plant Aggregates of Iowa Inc. (and subsidiaries Midwest Fly Ash & Materials Inc. and Livestock Waste Management Inc.).
  • Fly Ash Products Inc.
  • Mineral Specialties Inc.
  • VFL Technology Corporation.

In 2014, Headwaters Resources acquired the assets of Sinew Inc. and LA Ash Products and Services. In 2016, Headwaters Construction Materials acquired the assets of Synthetic Materials, LLC (SynMat). The following year, Boral Limited acquired Headwaters Incorporated, including its Resources and Plant Services divisions.

Green Cement Inc. commenced operations in 2011 as VHSC Cement, LLC. Based in The Woodlands, Texas, the company developed and introduced a concrete binder, PozzoSlag® (“1.0”), capable of 50 percent or higher portland cement replacement, plus performance characteristics that included early set times and long-term strength development. Produced in an environmentally friendly way, PozzoSlag® enabled reductions in carbon dioxide emissions approximately 90 percent below those associated with the manufacture of ordinary portland cement. The newest generation of Pozzoslag® can replace up to 100 percent of the ordinary portland cement in concrete and generates up to 99 percent less CO2 emissions. VHSC became known as Green Cement Inc. in 2021 and Green Cement, LLC in 2023.
