Nissan implements building sheets from paint waste

Nissan has partnered with the Takayama Group in Japan to commercialise calcium carbonate recovered from its vehicle paint shops.

The materials are being reused in two newly launched building products, TS-12 and TS-20 sound-insulating sheets.

Nissan expects this initiative to reduce annual waste by approximately 1,200 tonnes and lower waste disposal costs by 25 million yen.

The recovered material comes from Nissan’s dry booth system at its Tochigi and Oppama plants. Instead of water, the system uses filters filled with calcium carbonate to capture paint mist, enabling the material to be recovered in a dry, solid form.

This breakthrough allows the byproduct to be reused efficiently as a raw material rather than discarded.

The TS-12 and TS-20 incorporate the recovered calcium carbonate into sound-insulating sheets for building applications.

Nissan said it is exploring additional applications for recovered calcium carbonate, including its potential use in automotive components beginning in 2030.
