【The Importance of Eco-Friendly Product Development】
From the perspectives of climate change mitigation and resource circulation, adopting environmentally conscious materials has become an urgent priority in manufacturing. In particular, the use of recycled materials and biomass resins is increasingly required in plastic product development.

Kawamura Kikai Co., Ltd. leverages its CFRTP (Carbon Fiber Reinforced Thermoplastic) molding technology to reduce environmental impact through the introduction of bio-based materials and the reuse of recycled resins.

【What Are Biomass Resins?】
Biomass resins are renewable plastic materials derived from plant-based resources. Representative examples include:
・Polylactic acid (PLA): Derived from corn, offering high rigidity and biodegradability
・Polyamide 11 (PA11): Derived from castor oil, balancing flexibility and heat resistance

These materials are increasingly used as alternatives to petroleum-based resins.
The company is also developing NFRTP technology that combines natural fibers with biomass resins.

【Remolding with Recycled Pellets (Re-Pellet Materials)】
Re-pelletized materials made by crushing and reprocessing scrap and production offcuts are key to circular manufacturing. By leveraging the characteristics of thermoplastic resins, reheating and remolding processes have been established.
・Reduction of cost and environmental impact through reuse of CFRTP scrap
・Adjustment of mechanical properties by blending recycled and virgin materials
・Prototyping and general-purpose part production using reclaimed material

This system promotes environmentally responsible product development while minimizing material loss.

【Composite Technology with Natural Fibers】
The company also supports composite development using natural materials:
・Compatible with natural fibers such as hemp (HEMP), linen (flax), and coconut fiber
・Biodegradable product molding possible through combinations with PA11 or PLA
By utilizing these bio-based materials, eco-design that considers end-of-life disposal becomes achievable.

【Product Applications Through Integration with CFRTP】
NFRTP technology combining natural fibers and biomass resins is being applied to various products:
・Lightweight, high-strength drone components
・Automotive lightweight brackets and interior parts
・Sports and leisure housing products
・Eco-designed appliance housings and consumer goods

With molding capabilities exceeding 400°C, heat & cool control systems, and dedicated heating equipment, Kawamura Kikai Co., Ltd. continues to expand its support for advanced composite materials.

【Integrated Support Toward Sustainable Product Commercialization】
A comprehensive in-house system supports the commercialization of environmentally friendly materials—from material selection and prototyping to molding and post-processing.
This approach reduces design workload and outsourcing management burdens while ensuring reliable quality in sustainable product development.

【Summary】
As the transition toward a decarbonized society accelerates, product development utilizing recycled materials and biomass resins is gaining increasing attention. Building on its expertise in CFRTP molding and composite processing, Kawamura Kikai Co., Ltd. delivers proposals for environmentally friendly products using next-generation materials.
