ENVIRONMENTAL STEWARDSHIP

Engineering, Vertical Integration and a Sustainable

Business Model Drive Success at Hunter Facility

Our Hunter facility operates across all our business lines -- aggregates, cement and ready mix plants. The aggregates
facility, completed just five years ago, operates with some of the newest and most efficient equipment on the market.
And, while vertical integration is a financial benefit for the Company, it’s also an environmentally friendly business model.

Our Hunter Cement The site uses a filter press system that allows Hunter
Plant New Braunfels, Stone to use recycled water for as much as 70 percent
Texas
of its production needs, greatly reducing the need
for underground water in a water-challenged area.
“Our filter press system allows us to truly minimize
the amount of water we need to pump from
underground sources,” Aggregate Plant Manager
Pat Kinser said. “That has greatly reduced our
environmental impact and has helped preserve the
Trinity Aquifer.”

Additionally, the filter press system allows Hunter
Stone to operate without an inground settling pond,
a fact that Kinser said is greatly appreciated. “While
necessary at most operations, settling ponds take
up real estate, mean more work hours and more
hours on the equipment for building the ponds and
maintaining the accompanying berms and dams,”
he said. “The filter press system allows us to operate
without those concerns. It replenishes itself daily and
makes us incredibly efficient.”

In 2019, Hunter Cement installed an alternative
fuel handling system that allows the site to utilize
a substantial amount of tire-derived fuel to make
its product. The method allows Hunter to better
regulate the temperature in its kiln, making for a
more stable production environment. Additionally,
the system helps Hunter minimize the amount of
fossil fuels it consumes and pulls discarded tires out
of communities across Texas, helping the state rid
itself of an unwanted environmental hazard.
