Toyota recycled materials cut CO2 emissions in vehicle soundproofing

Toyota Motor Corporation has started collecting used clothing internally to use as a raw material for recycled fibers in vehicle soundproofing components. By shifting to soundproofing parts made from recycled fibers instead of new ones, the company can cut carbon dioxide emissions by about 50% while maintaining the same functional performance in vehicle bodies.

Toyota recycled materials in soundproofing components

The recycled fibers are used in soundproofing components such as dash silencers, which separate the engine room from the cabin, and floor silencers installed beneath the vehicle floor. These components together account for around five kilograms of material per vehicle, making them a meaningful area for emissions reduction.

Replacing imported fibers with recycled alternatives

Toyota currently imports most of its fiber materials from China. Through this initiative, the company is gradually replacing those imported fibers with recycled materials sourced from used clothing, strengthening supply resilience while lowering the overall environmental footprint of vehicle production.

In-house clothing collection and future targets

Toyota has been collecting used clothing in collaboration with Toyota City in Aichi Prefecture and other partners. In December 2025, collection boxes were installed inside company buildings, enabling regular in-house collection that has already reached about 400 kilograms per week.

Raising recycled material usage in new models

Looking ahead, Toyota aims to increase the recycled-material usage rate in new vehicle models launched in 2030 and beyond to more than 30% on average. The expanded use of recycled fibers in soundproofing components is positioned as a practical step toward achieving that broader sustainability target.
