Nissan and Takayama Group launch sound-insulating sheets from recycled paint shop byproducts
Nissan and Takayama Group have commercialized sound-insulating building materials made from calcium carbonate recovered from vehicle paint shops, cutting waste and CO2 emissions.
- about 1,200 tons
- 25 million yen
What Happened
During automotive painting, paint mist that doesn't adhere to vehicle bodies is captured using a dry booth system at Nissan's Tochigi and Oppama plants. Instead of water, filters filled with calcium carbonate trap the mist, allowing the material to be recovered in dry solid form for reuse.
The recovered calcium carbonate is used by Takayama Group to produce TS-12 and TS-20 sound-insulating sheets for buildings. Compared with conventional alternatives, these products are expected to reduce CO2 emissions by more than 30%.
Nissan expects this initiative to reduce annual waste by approximately 1,200 tons and lower waste disposal costs by 25 million yen. The company is also exploring use of the recycled material in automotive components starting in 2030.
Why this matters
This collaboration turns industrial byproducts into high-value materials, advancing the circular economy and reducing environmental footprint in manufacturing.
