Environmental Stewardship


Aggregate products have laid the foundation of contemporary life and our economy. Crushed stone is essential in building homes, schools, hospitals, roads and erosion control projects. Supplying quality stone and asphalt products to meet this need in an environmentally responsible manner is our goal. Aggregate producers recognize that the finite resources of the Earth require wise environmental stewardship to preserve the quality of life for future generations. Tilcon meets all requirements of state and federal environmental regulatory agencies. Our established reputation as an environmental steward, community leader and as a producer of quality aggregates and asphalt contributes to our success.

Our industry constantly strives to minimize the environmental impact of its activities. To find out more about how this applies to our products and production processes please see our Products section and the page 'How Asphalt is Produced' in this Community section.

Our Partnership with the Wildlife Habitat Council

Tilcon and CRH are committed to improving wildlife habitat through the enrichment of pre-existing habitat and the establishment of new habitat on the company’s land. To put this commitment into action, in 2004 CRH Americas began partnering with the Wildlife Habitat Council (WHC), a non-profit organization dedicated to restoring and enhancing wildlife habitat. Created in 1988, the WHC helps large landowners, particularly corporations, manage their unused lands in an ecologically sensitive manner. To learn more, visit

The Mt Hope Wildlife Habitat Site, which was certified in 2010, is the first to be created at Tilcon. The project began in 2009 when a team of employees embarked on three major projects at Mt Hope – fish management, bird boxes and a nature camera. The project was re-certified in October 2012 by the Wildlife Habitat Council for 'outstanding commitment' to a wildlife habitat enhancement program.

The wide variety of fish in Mt Hope Lake is an important part of the habitat because they provide food for the birds and mammals in the area, enabling them to flourish. The team is also partnering with Rockaway Township Sportsman’s club on fish management. The fishermen keep logs and the team analyzes the data and creates maps showing the populations.

Three types of boxes have been constructed throughout the site, for bluebirds, wood ducks, and bats. The project was created to examine a wide variety of bird species and create a home best suited for each of them. As the use of the boxes is monitored, the team has gained a greater understanding of each species’ needs. In the future, placards will be placed to share the findings with the public to foster community awareness, education, and enjoyment.

The use of nature cameras is a baseline project in conjunction with the bird boxes and fish management inventory projects. Through photo documentation, the team can establish a monitored and controlled environment. A motion-sensor infrared camera is set up at a different location each week. It can either be turned in various directions or moved to an entirely different location. The photos will be shared with the public for educational purposes.

Among the types of wildlife on our Site are Canadian geese, mute swans, blue jays, great blue herons, owls, redwing blackbirds, hawks, turkeys, American toads, green frogs, black bears, white-tailed deer, green darners, eastern pondhawks, dragonflies and numerous species of fish. Trees include red maples, yellow birch, ironwoods and scrub oak.

In total, the Wildlife Habitat Council has certified 640 sites as Wildlife At Worksites. The certification program recognizes outstanding wildlife habitat management and environmental education efforts at corporate sites and offers third-party validation of the benefits of such programs. Certification requirements are strict and require that sites apply for periodic renewal.

Keep Rockland Beautiful

In April 2012, Tilcon sponsored local non-profit organization Keep Rockland Beautiful's Great American Clean Up which helped local residents remove debris and litter from parks, streets and local waterways. Keep Rockland Beautiful's mission is to create a cleaner, more beautiful Rockland County. The organization coordinates many community clean-up activities and gives talks in local schools to educate children about how they can get involved in keeping their local environment clean.

In June 2012 several Tilcon volunteers joined forces with Keep Rockland Beautiful's members to clean up a section of Haverstraw Bay, adjacent to Tilcon's Haverstraw Quarry. After several hours hard work, the bay was cleared of several truck and car tires using manpower and a Tilcon long reach excavator.

Tilcon was awarded Keep Rockland Beautiful's Business Sponsor 2012 Award for the work that we have done over recent years. The award was accepted on our behalf by Tilcon NY Environmental Manager John Van Zetta, pictured below with KRB's Gerry Collins. Click below to read our news item about the award presentation.

We have worked with Keep Rockland Beautiful again in 2013 and 2014, sponsoring a Clean Up as part of the Great American Clean Up each spring. In 2013 a group of Tilcon volunteers cleaned up the Tomkins Cove dock, Tomkins Cove, NY of tires and debris washed ashore from the Hudson River and in spring 2014 we cleaned a stretch of Casper Hill Road, Valley Cottage, NY close to our New York corporate headquarters.
