Circular Economy
Stone processing inevitably produces offcuts and slurry; the question is whether they go to landfill or back into production. Hengsheng runs a sorting and recovery system: offcuts return as mosaic, engineered slab and construction aggregate, while slurry by-product becomes coating filler and road base material. Comprehensive waste utilisation exceeds 85%, with the aim of a demonstration plant for the circular economy.
Core Strengths
- Sorting at source: offcuts and slurry are collected by stone type, size and cleanliness beside the line, so mixing does not destroy reuse value.
- Offcuts returned to use: sized offcuts go to mosaic and inlay; crushed material becomes engineered slab and construction aggregate, re-entering the building materials supply chain.
- Slurry converted: stone powder is processed into coating filler and road base material, displacing part of the virgin mineral input.
- Measurable utilisation: comprehensive waste utilisation exceeds 85%, compiled monthly into management review, with new reuse routes continually sought.
Key Figures
Service Process
- Sorted collection: offcuts and slurry gathered by category beside cutting, polishing and forming.
- Crushing and screening: crushed material separated by particle size for different reuse routes.
- Slurry treatment: settled, dewatered and dried into a usable powder.
- Reuse production: offcuts feed mosaic and engineered slab lines; powder supplies filler and road base.
- Statistics and review: utilisation and destinations compiled monthly, with unrecovered fractions analysed.
Applications
- Mosaic and inlay product manufacturing
- Batching for engineered slab and construction aggregate
- Supply of coating filler and road base material
- In-plant waste sorting and slurry treatment
Sustainability & Certification
Recycling reduces landfill and virgin mineral extraction, closing the loop with quarry reclamation: 99.7% utilisation at quarry level and above 85% in processing.
Reuse lowers the material and energy footprint per unit, and with 95% water recycling and solar power the overall environmental burden falls year on year.
Deep Selection Guide
Circularity hinges on sorting: mixed waste can only be landfilled, sorted waste is a raw material. Ask how material is sorted and where it actually goes, not only the utilisation percentage. Prefer products with recycled content — mosaic, engineered slab — and ask suppliers to state the recycled proportion and performance data. Modular layout at design stage also reduces complex cutting and cuts waste at source.
- Selection criteria：The conditions of use at Mosaic and inlay product manufacturing dictate the stone and the process, while Sorting at source governs how the finished face reads; only when both are settled should an order be placed.
- Specification & thickness：Control tolerance with Overall waste utilisation (>85%) and set panel size to Batching for engineered slab and construction aggregate; corners and cut-outs must be called out on the detail drawing beforehand.
- Acceptance & records：Acceptance focuses on Offcuts returned to use, with figures and images retained; if a dispute arises it can be traced by batch code back to production and testing.
- Sustainability：Recycling reduces landfill and virgin mineral extraction, closing the loop with quarry reclamation: 99.7% utilisation at quarry level and above 85% in processing. Set it out in the contract and acceptance documents, and bring it into line with local environmental rules.
On Circular Economy, the value Hengsheng brings is not the material alone but whether selection, fabrication, QC and delivery can be closed into an auditable loop that keeps programme and quality under control together.
FAQ
- Do products made from recycled material perform worse?
- No. Offcuts are routed by use: sized pieces become mosaic and inlay, crushed material becomes engineered slab and aggregate, and powder becomes filler and road base. Each reused product is tested to the relevant standard and released only where performance matches its intended use.
- How is the 85% utilisation calculated?
- Recovered waste weight divided by total waste generated over the period, covering both offcuts and slurry. Figures are compiled monthly into management review, and unrecovered fractions are analysed with new routes sought.
