Energy Saving & Emission Reduction
Power consumption in stone processing concentrates in polishing, cutting and compressed air, so reduction has to start there. Hengsheng has installed rooftop solar across the production base covering over 80% of plant electricity demand, manages consumption plant-wide through an intelligent energy system, and combines efficient lighting, variable-frequency compressors and waste-heat recovery to target 30% annual carbon reduction with 95% process water recycling.
Core Strengths
- Solar coverage: rooftop photovoltaic systems across the plant cover more than 80% of electricity demand, so daytime high-consumption operations run on self-generated power.
- Energy made visible: the intelligent energy system collects consumption by machine and process, warning on abnormal spikes, so saving becomes a managed indicator rather than a slogan.
- Equipment retrofit: efficient lighting, variable-frequency compressors and waste-heat recovery are fitted throughout, raising efficiency in compressed air and drying.
- Targets that can be checked: a 30% annual carbon reduction target and 95% process water recycling are compiled monthly and reviewed in management review, moving towards carbon neutrality.

Service Process
- Energy audit: consumption baselines built by machine and process to identify the main loads.
- Clean energy substitution: solar installed and self-generated power scheduled to the right hours.
- Equipment retrofit: efficient lighting, variable-frequency compressors and waste-heat recovery installed.
- Intelligent control: consumption monitored and alarmed in real time, with scheduling continuously optimised.
- Performance review: carbon and water indicators compiled monthly into management review.
Applications
- Rooftop solar generation and self-consumption scheduling
- Energy monitoring of polishing and cutting operations
- Compressor variable-frequency retrofit and waste-heat recovery
- Monthly energy performance review and management review
Sustainability & Certification
Solar power, water recycling and waste-heat recovery together form the reduction path: a 30% annual carbon target and 95% process water recycling, compiled monthly and available externally.
Energy and quality management share one set of process records: less rework and scrap lowers energy per unit, with data flowing between the ISO 9001 and ISO 14001 systems.
Deep Selection Guide
Test a reduction commitment by asking where the electricity comes from, where it is used and how much has been cut. Answering all three means a real pathway rather than a stated goal. In ESG or green building documentation, ask suppliers for energy per unit, the share of clean energy and the measurement basis and period behind carbon targets, and prefer partners able to provide monthly data. For power-intensive orders, ask whether production can be scheduled at off-peak hours or during peak solar output.
- Selection criteria：When choosing stone for Rooftop solar generation and self-consumption scheduling, ask first whether Solar coverage holds, then look at colour and veining - reverse the order and the work usually has to be redone.
- Specification & thickness：Set size by Electricity covered by solar (80%+) and thickness according to Energy monitoring of polishing and cutting operations; junction and cut-out positions must be clear on the drawing so no second machining is needed on site.
- Acceptance & records：Energy made visible is a mandatory pre-dispatch check, with results and images archived; accept on site by number, and batch records can be retrieved if a dispute arises.
- Sustainability：Solar power, water recycling and waste-heat recovery together form the reduction path: a 30% annual carbon target and 95% process water recycling, compiled monthly and available externally. Fold this into the acceptance documents and check it against the green material rules that apply locally.
Hengsheng approaches Energy Saving & Emission Reduction by putting quarry, fabrication, testing and delivery on one traceable chain, so the client receives evidence on programme, quality and compliance, not merely a consignment of stone.
FAQ
- How much of the plant's electricity does solar cover?
- Rooftop photovoltaic systems across the production base cover more than 80% of demand, managed through an intelligent energy system that schedules high-consumption operations into hours of stronger solar output.
- How is the 30% carbon reduction calculated?
- It is based on energy consumption per unit, combined with self-generated solar output, equipment retrofits — efficient lighting, variable-frequency compressors, waste-heat recovery — and process optimisation. Figures are compiled monthly and reviewed in management review against the 30% annual target.
