We take our responsibility for protecting the environment seriously. Our commitment to build a better community includes: being resource efficient, minimizing impact on the natural environment, and eliminating unnecessary energy waste from our equipment and operations.

Asphalt and concrete materials are crushed and filtered to create new aggregate for recycled products, and hundreds of thousands of gallons of oil have been recycled.

Minimize Distribution of Vehicular Pollution

Sunroc maintains strict idling and driving standards for all company vehicles and operational machinery, helping us eliminate unnecessary pollutants from our communities.

Recycled Materials as a Product Offering

Recycled concrete and asphalt products are available to all our customers. We make it that much easier for our clients to build sustainably.
