Environmental Management

We understand that the raw materials we extracted including stone, sand and gravel and the fuel or other materials we purchased for our operations are finite resources that require us to extract and use them in an increasingly efficient manner.  To practice good environmental stewardship, conserving resources, and restoring our sites for future generations is a commitment we have made in order to create better harmony between our operations and the environment.

Quarry Rehabilitation

When planning and operating our quarry sites, we always consider the impacts that we may have to the environment. The Quarry Restoration Plan we have for our quarry sites addresses the issues of landscaping and habitats, vegetation establishment, species development and other natural resource conservation. The plan also contains professional landscaping designs and recommendations for management programs to restore the quarry sites and create a habitat able to evolve into the kind of advanced ecological community found in the adjacent areas.

Pollution Control & Monitoring

In recognition of our impacts, mainly dust and noise, to the surrounding area, the environmental management at our operations focuses on the isolation of the emissions at their sources. The combined effect from our fully enclosed production lines, the dust extracting and filtering system, and other dust suppression measures that we installed at each emission source point allowed us to meet the most stringent air quality standards.  Our Noise Pollution Control Plan which put together selection of low noise level machinery, isolation of noise source, prevent maintenance measures, and other administrative control ensures the Acceptable Noise Levels suggested by the Environmental Protection Department and other legal requirements can be met.

We put in place environmental monitoring programs to ensure the emissions will be minimal and not harm the surrounding environment. Our Noise Monitoring Program covers 100% of our work sites, monitors the noise levels at the sensitive receivers.  While the Air Quality Monitoring provides accurate data for evaluating the effectiveness of the dust pollution control measures we have in our work sites.  We also monitor the water quality at the discharge points in our quarry sites protect the water body from being polluted.

Waste Reduction

Environmental management - waste reduction

Waste reduction is an integral part of our sustainability strategy.  By improving our communications with customers we have minimized the volume of returned concrete due to previously inaccurate ordering.  With the investment in the slurry treatment at concrete plants and the administrative control for monitoring the waste volume we have reduced our solid waste disposal to landfill sites significantly.

Our aggregate production lines accept surplus rocks from local development projects, turn the natural resources into usable aggregates while prevent them from being disposed to landfill sites or transported to other regions generating excessive Greenhouse Gases.

Water Conservation

Environmental management - Water conservation

In the context of water conservation we aspire to reduce the water consumption in our operations while not polluting any water bodies. The No Discharge policy we have in all our concrete batching plant operations has help drive innovation and good practices to support meeting the challenging target.

At our quarry sites we divert the natural stream courses to prevent them from being polluted, while the artificial lagoons collect the rain water and other surface runoff which is used for dust suppression within the quarry operations.
