The project partners toured the facilities of battery recycler, Accurec.

The project partners toured the facilities of battery recycler, Accurec, who have designed and tested an innovative microwave treatment technology for Li-ion battery waste as part of the CloseWEEE project. The process enables recovery of critical raw materials – metals and graphite – which with appropriate treatment, can be re-used in battery manufacture or in other applications.

Accurec has long been involved in the recycling of batteries – Founded in 1995 the company now processes 4.5 million kilograms per year of NiCd, NiMH and Li-ion batteries. As part of the CloseWEEE project, Accurec has designed and tested a safe, and environmentally friendly, innovative microwave treatment technology for Li-ion battery waste. In the process, the batteries undergo a pretreatment of discharging and mechanical processing. The Li-ion battery material is then fed into a microwave furnace where the material is heated up rapidly and the organics (electrolytes and separators, etc.) are pyrolyzed/evaporated. It produces electrolyte-free material for subsequent hydrometallurgical treatment for recovery of metals (Co, Ni, Mn, Li) and graphite. For more information, get in touch at info@accurec.de.
