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.
