Burg Machinery
The battery recycling division, part of Roster Ltd.
Our mission
Batteries are made from raw materials that are difficult to source and shouldn't be lost after a single life cycle. Burg Machinery's mission is to keep those critical resources — lithium, nickel, cobalt, copper and aluminium — in circulation rather than letting them become waste. We apply patented, eco-friendly recycling technologies to recover materials at the highest possible purity and the lowest possible environmental footprint, supporting a genuinely circular economy. In 2023, we redirected our full focus to lithium-ion battery recycling — the area where that contribution is needed most.
Part of Roster Ltd
Burg Machinery EOOD is a wholly owned subsidiary of Roster Ltd, which specialises in the recycling of ferrous and non-ferrous metals. The recycling of aluminium and copper parts is carried out in the mixed metal recycling plant of Roster Ltd, equipped with the latest technology from a large Italian manufacturer.

Technology, safety and a closed loop
Eco-friendly
Our eco-friendly recycling technology saves 8.1 tonnes of CO₂ per tonne of recycled batteries, compared to the primary extraction of the raw materials.
Safety
Safe storage, handling and transportation of lithium-ion batteries is our priority. Safety is ensured by specially designed packaging and discharge to 0 volts.
Efficiency
Highest purity grades due to the low-temperature process; solvents of the electrolyte and lithium can also be returned to the material cycle. Black mass at over 99% purity.
Closed loop
Burg Machinery is committed to achieving complete autonomy in the recycling of lithium-ion batteries by implementing a fully closed-loop system.
