ISO 14001:2015 Environmental Management System
Stone is an industry of extraction as much as fabrication, so environmental performance cannot be judged only inside the factory fence. Hengsheng's ISO 14001 system treats quarry and plant as one chain: dust, wastewater, waste and energy are controlled together, audited and certified by SGS under certificate HK-EMS-0412-2024, valid 2024 to 2027.
Core Strengths
- Full-chain control: environmental management spans quarry restoration, block transport and plant polishing and resin treatment — not merely the discharge points at the factory boundary.
- Quantified indicators: annual targets are set for dust emission, water recycling, waste utilisation and unit energy use, tracked monthly and reduced through rooftop solar and variable-frequency equipment.
- Independent surveillance: audited by SGS with annual visits; environmental non-conformities enter the corrective and preventive action process and must be verified as closed.
- Support for green procurement: system certificates and environmental indicators are available to support green building assessment and owner ESG reporting.
Key Figures
Service Process
- Aspect identification: wastewater, dust, noise, waste and energy sources listed for each process.
- Targets and programmes: annual reduction and recycling targets set with supporting equipment and management plans.
- Operational control: settling and recycling water systems, dust extraction and noise monitoring run to procedure and logged.
- Performance monitoring: indicators compiled monthly, deviations triggering corrective and preventive action.
- Third-party audit: annual surveillance by SGS with recertification every three years.
Applications
- Environmental performance evidence for green building rating projects
- Supply-chain environmental data collection for owner ESG reports
- Prequalification requirements for environmental systems on government works
- Due diligence on mining and processing compliance for overseas projects
Sustainability & Certification
The system brings quarry ecological restoration into scope: partner quarries carry out staged vegetation restoration and soil and water conservation with a 1:1.2 extraction-to-restoration ratio, and undergo periodic third-party environmental impact assessment.
At the plant, settling and recycling systems deliver 95% water reuse, while sorted waste is reused in mosaic, engineered slab and construction aggregate at over 85% utilisation; rooftop solar covers more than 80% of electricity demand.
Deep Selection Guide
The value of environmental certification lies in whether the data can be cited. When requesting indicators, fix the measurement basis and period, and confirm third-party audit, so you are not left with unverifiable self-declared numbers. In tender documents and ESG reports, cite the certificate number and auditing body directly, and attach key indicators such as water recycling and waste utilisation. Where a project targets green building rating, also request radionuclide testing and low-VOC evidence such as GREENGUARD Gold, so the environmental system certificate sits within a complete chain of proof.
- Selection criteria：Put Environmental performance evidence for green building rating projects first in the selection and Full-chain control second - that order avoids most downstream disputes.
- Specification & thickness：Certificate number (HK-EMS-0412-2024) is the core of the specification and the rest is fine-tuned to Supply-chain environmental data collection for owner ESG reports; junctions, cut-outs and shaped edges must be spelled out on the fabrication drawing.
- Acceptance & records：Checks on Quantified indicators are completed and evidenced before dispatch and accepted on site by number; production and test records can be pulled by batch when needed.
- Sustainability：The system brings quarry ecological restoration into scope: partner quarries carry out staged vegetation restoration and soil and water conservation with a 1:1.2 extraction-to-restoration ratio, and undergo periodic third-party environmental impact assessment. Include this requirement in the acceptance pack and confirm it against local green material standards.
With ISO 14001:2015 Environmental Management System, what Hengsheng emphasises is auditability: selection has a basis, fabrication has records, delivery has milestones, and the client holds commitments that can be checked on quality and programme.
FAQ
- How far does the environmental system reach?
- It covers the full production chain: quarry restoration, block transport, and polishing and resin treatment at the plant, with dust, wastewater, waste and energy controlled together and reviewed by SGS annually.
- Can you supply environmental data usable for green building rating?
- Yes. Beyond the ISO 14001 certificate, indicators such as water recycling rate, waste utilisation, unit energy use and the carbon reduction target are available, and can be combined with product-level documents including GREENGUARD Gold and CE to support green building assessment and ESG reporting.
