Stewart Materials


Material processing customizes aggregate, sand and rock for a variety of applications, and to meet and match virtually any specification stipulated by a municipality, project partner, or other governing body.

These same processes preserve and sustain the local environment.


Once a site completes its mining lifecycle, it is reclaimed. Stewart Materials’ responsible reclamation practices dictate site-specific measures that include terraforming the lake edges and specifying and planting beneficial trees in appropriate densities. Depending on the site and its characteristics, we typically exceed the slope requirements, often by a two-to-one ratio.

Care in the selection and planting of native and beneficial grasses are another element in the formation of new natural habitats and environments. Over time, natural habitats for freshwater fish and plant populations regenerate.

Ours is a temporary land use.

Stewart Materials extracts aggregate materials as an environmentally safe, repeatable, low-impact sustainable mining practice. In-house geologists team with hydrogeology and restorative ecology professionals and regulatory policymakers to develop improved methods.

Aggregate material recovery and processing are subject to a stringent regulatory structure. Local regulations focus on land uses and growth, natural resources and public safety. In part, state regulation addresses water quality and quantity, wetlands, safe reclamation and state-protected, wetland-dependent wildlife. State regulation also solicits input from the Florida Fish and Wildlife Conservation Commission and the Florida Department of State Division of Historical Resources.

In addition to being subject to multiple local, state and federal safety regulations and mandates, including the U.S. Department of Labor, Mine Safety and Health Administration (“MSHA”) bi-annual safety inspections, Stewart Materials has an established safety policy which includes, in part that Stewart Materials:

  • Uses only safe, sustainable processes and practices.
  • Provides employees a safe working environment with the tools, equipment, education, training, intervention and support to maintain safe-working conditions at all times.
  • Maintains an aggressive, proactive stance on waste reduction, energy conservation, and recycling and reclamation.
  • Promotes the same responsible stewardship among its partners, suppliers, sub-contractors, carriers, haulers and customers.
  • Conducts scheduled and periodic reviews of safety, health and environmental practices, on site, in the field and throughout all its processes.
  • Identifies, corrects and applies interventions, updates and amendments to any and all safety practices, equipment and methods, as necessary.
  • Engages and promotes development of logical, science-based and cost-efficient safety, health and environmental legislation and regulation.
