By evaluating each of our operations on its environmental performance, Hanson demonstrates a comprehensive approach to sustainable land management. Our critical focus areas are quarry rehabilitation, water management and biodiversity.

We also have dedicated programs to promote sustainable manufacturing and sustainable transport.

• We are continuing to rehabilitate local ecosystems and reduce our environmental impact through ongoing rehabilitation projects.
• This represents a significant part of our quarrying business, as 80% of our quarry land is actually undisturbed.
• Rehabilitated areas are covered with soil and overburden found on-site using techniques that reproduce the topography of the terrain and tailing ponds are capped with layers of binding materials.
• Horticulturalists often work with our quarry managers, providing expert advice for the rehabilitation of terminal faces and worked-out areas.

• We measure, report and set sustainable water reduction targets for our business operations through a stringent Environmental Management System.
• Our Bass Point quarry’s Water Management Plan won the CCAA Extractive Industries Environmental Award, with a dedicated lab technician on-site to monitor water quality at each discharge point.
• In all of our quarries, water discharge flows are carefully monitored to ensure there is no adverse impact on local waterways or ecosystems.

• Through our rehabilitation work, many rehabilitated quarries are now home to local wildlife including wallabies, wallaroos, echidnas and native bird species.
• Our Clarence quarry won the CCAA’s Quarry Environmental Performance Award after increasing the number of endangered Blue Mountains water skink living in its swampland by carefully monitoring ground water quality with piezometers.
