A secondary lead smelter built to keep the world green.
Bergsoe Metals Co., Ltd (BML) converts waste battery scrap into valuable commodities at our Saraburi plant — with technology and processes engineered for efficiency and environmental stewardship.
"Keep the world green — with our committed team of talents and advanced green technologies."Bergsoe Metals Co., Ltd
Battery waste is generated at an alarming rate across the globe and is a serious risk to the environment if it isn't managed responsibly. We exist to close that loop: recycling lead-acid battery scrap into pure lead, lead alloys, recyclable plastics and reusable clean water.
Pure lead and alloys go back into new batteries that power vehicles and industry. Recycled plastics become new products. Treated water goes back into our own production. We aim to create value for society, for our customers and for our suppliers — and to be trusted by all three.
What we hold ourselves to
- Continuously improving products and services to meet customer needs
- Making customers satisfied and becoming the most trusted supplier
- An interdependent balance between our responsibilities to customers, employees, society and shareholders
- Successfully implementing our commitments
Reliable for society, customers and suppliers.
