The lead recycling process in Torishima is designed to reduce the environmental burden by using top of the line equipment and machinery, and by housing the entire lead-handling process indoors.
We are diligent about our quality assurance and keeping our environmentally friendly promise.
Our products are the fruits of our teams’ metallurgical and technical process development, aided by online monitoring of the process itself.
With the newest recycling and environmental professional know-how, our lead recycling process is still evolving.

The adjustment of the composition of raw materials to feed the furnace takes place under a flow hood.
The raw materials are smelted in a reducing environment, to produce pig lead.
Pig lead is then refined in the refining kettle to remove undesired elements.
The final product is continually cast into 25 and 50kg ingots.
The line can stock 50t of ingots. The final appearance check is performed here.
Only materials that meet our quality standards are loaded onto trucks inside the factory, and shipped to our customers.
