- Astemo Recycling Technology strengthens recycled PBT for automotive applications.
- New recycling method improves recycled material quality and durability.
Astemo Ltd announced on July 15 that it has jointly developed an innovative recycling technology with Japan-based Tohoku University Graduate School of Environmental Studies to restore the mechanical strength of degraded plastics. The technology is expected to support automotive parts manufacturing by improving the quality of recycled engineering plastics while promoting a circular economy. Through this development, the company aims to increase the practical use of recycled materials without compromising product performance or reliability.
New Process Restores Strength of Degraded PBT
The jointly developed technology focuses on degraded polybutylene terephthalate (PBT), an engineering plastic widely used in automotive components. By introducing a specially designed additive, the process reconnects broken polymer chains that have deteriorated over time. This restoration technique enables degraded PBT to regain its physical characteristics, allowing recycled material to perform much closer to newly manufactured resin while extending its potential use across automotive applications.
Property Recovery Verified Through Material Analysis
Astemo confirmed that the newly developed process successfully restores reduced tensile strength to levels close to those of the original material. In addition, researchers evaluated different additive mixing ratios and processing techniques to determine the optimal conditions for restoring material properties. According to the company, these findings are expected to improve the consistency and overall quality of recycled plastics while expanding the range of applications where recycled engineering materials can be utilized.
Potential Automotive Applications of the Recycling Technology
The company plans to apply this technology across future automotive products that incorporate recycled materials. Initial applications are expected to include automotive electronic component housings, where stable mechanical performance is essential. By maintaining consistent material quality, the technology could also support mass production while enabling broader adoption of circular materials throughout vehicle component development and manufacturing.
Expected Benefits of the Technology
The recycling technology is expected to provide several advantages for automotive manufacturers and material suppliers.
- Restores the strength of degraded PBT plastics.
- Improves the quality of recycled engineering materials.
- Supports wider adoption of recycled automotive components.
- Enables more stable material quality for mass production.
- Advances product development using circular materials.
Astemo's Planned Utilization Strategy
Looking ahead, Astemo intends to expand the use of this recycling technology within future automotive products while supporting broader sustainability initiatives. The company expects the process to increase recycled material utilization, stabilize manufacturing quality, and promote product designs based on circular materials. These efforts are intended to contribute to resource conservation and strengthen the role of recycled engineering plastics in next-generation automotive manufacturing.
