We ensure the air we release is pure, safe and fit for breathing.
A lead smelter is only as good as its controls. Ours are built into every stage: sealed furnaces, filtered air, recycled water, recovered plastic — and monitoring that we publish.
What "advanced green technology" actually means here.
Sealed air filtration
Furnace and process gases are captured at source and passed through the air filter and scrubber system, which removes smoke and particulate before any air leaves the building.
Closed-loop water
Wastewater from battery breaking is treated to clean, reusable water and returned to the process. Treated and untreated water are both contained on site — nothing goes to the river.
Plastic recovery
Polypropylene casings are separated in the breaking system and sent on as recyclable plastic, becoming new products instead of landfill.
Continuous monitoring
Stack, fence-line and water quality are measured on a fixed schedule against Thai DIW and MNRE limits.
How battery scrap becomes clean lead
One battery in, one battery's worth of lead out — and the plastic, acid and water accounted for along the way.
Scrap received
Weighed, assayed, stored under cover
Battery breaking
Plastic, acid, grids and paste separated
Desulfurisation
Paste conditioned to cut furnace emissions
Rotary smelting
Oxygen-burner furnace, gases to filter & scrubber
Electrolytic refining
Bullion to 99.994% pure lead, or alloyed to spec
Casting
Ingots, bundled and certified
→ Air
Captured at every hood and furnace. Filtered. Monitored at the stack.
→ Water & acid
Acid neutralised; water treated and reused in-process. Zero discharge to the environment.
→ Plastic
PP casings recovered and recycled into new products.
A treatment plant, not a drain.
Acid and wash water from battery breaking go straight into our on-site treatment plant. The acid is neutralised, solids are separated, and the water comes back clean enough to reuse in production.
Treated and untreated water are both contained inside the site. Nothing is discharged to the river.
Electrolytic refining, not just fire.
Rotary-furnace bullion is cast into anodes and refined electrolytically: lead deposits on the cathode while impurities stay behind in the anode slime. It is the route to our 99.994% grade — and the electrolyte circulates in a closed system.
Anode plates → electrolytic cells → cathode lead → melting and casting → XIN XIN.BML99.994 ingots.
Inside the plant.
Air filtration
The system that scrubs every cubic metre leaving the process.
Rotary furnace
Oxygen-burner rotary furnace with hooded charging and tapping.
Electrolytic refining
Bullion anodes to 99.994% cathode lead, then cast into the two LME brands.
Quality laboratory
Spectrometer analysis of every incoming lot and every cast.
Environmental performance
What leaves the plant, in numbers.
Wastewater treated and reused
Water from battery breaking is treated on site and returned to the process. Treated and untreated water are both kept inside the plant.
Waste leaving the factory
Nothing is discharged to the river or dumped. Acid is neutralised, plastic is recovered, slag and residues are handled inside the licensed site.
Recycled input
Every tonne of lead we sell started life as a used battery or lead scrap — no mined ore.
Quarterly stack, fence-line and water monitoring results will be published here against the DIW / MNRE legal limits.
Care that goes past the fence.
Our factory is laid out as a garden — a safe, clean and healthy place to work. We run health check-ups twice a year for every employee, and extend them to children and elders in the neighbouring community.
Regular sporting events keep the team close. Relationships here go beyond the job: our people treat each other as one team, at work and outside it.
Biannual health checks
Every employee, every six months — including blood-lead monitoring.
Community clinic days
Free check-ups for neighbouring children and elders.
