Aerial view of the FUNMETAL secondary lead refinery in Mariara, Carabobo, Venezuela

Recovered lead. Recycled plastic. Managed at one facility.

We separate spent batteries into lead, polypropylene and electrolyte. The lead is refined, the plastic pelletized and the acid neutralized on site.

The circular economy of lead.

When a lead-acid battery reaches the end of its life, it does not have to end up in a landfill. A spent battery arrives at our facility, and we break it apart to separate the lead paste, metallic grids, polypropylene casing, and sulfuric acid.

The lead is smelted, refined to 99.98% purity, and cast into new ingots. The plastic is pelletized, and the acid is neutralized and treated. Those ingots become new batteries, and when those batteries reach the end of their life, the cycle starts again. Every ingot we produce was a battery, and every battery we process gets a second life.

Why secondary lead matters.

Every battery we recover means energy saved, ore left in the ground, hazardous waste diverted, and compliance made simpler.

01 · Energy

Energy savings

Recovering lead from a spent battery takes less energy than mining and smelting ore for the same tonne. No pit, no tailings.

02 · Resources

Resource conservation

Our feedstock is recovered from spent batteries. We refine existing lead into new ingots for industrial use.

03 · Waste

Waste diversion

Lead-acid batteries contain lead, acid, and plastic, all hazardous if improperly disposed. Our process separates these materials for recovery and treatment.

04 · Compliance

Regulatory alignment

Sourcing recycled lead supports your organization's ESG commitments and compliance with extended producer responsibility (EPR) regulations worldwide.

03  /  Our commitment
Engineered controls

Environmental responsibility, engineered in.

We built an acid neutralization line, a baghouse and a water treatment plant on the same campus as the furnaces. Qualified buyers walk all three on a plant visit.

Circular supply

Every container is lead that was never mined.

Sourcing recycled lead supports the circular economy, and your compliance requirements. Every container you buy from FUNMETAL is a container of lead that was never mined.
