Recycling

Battery parts can be recycled without crushing or melting

Researchers at Aalto University have discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy.

Is battery recycling environmentally friendly?

In a new study, researchers at Aalto University have investigated the environmental effects of a hydrometallurgical recycling process for electric car batteries. The carbon footprint of the raw material obtained by the recycling process studied is 38% smaller than that of the virgin raw material. The difference is even greater if copper and aluminium recovered during mechanical pre-treatment are included.

Not all plastics are created equally – from milk jugs and soda bottles, which are readily recyclable, to multi-layered packaging that increases shelf life and requires less material but is less recyclable – the challenge is for researchers to design a process that allows more of the plastics we use in our everyday lives to end up in our recycle bins rather than the local landfill.
