Panasonic's Kinari: A Cellulose-Based Alternative to Plastics

Panasonic Holdings Corporation has developed Kinari, a bio-based composite resin containing up to 85% cellulose fiber, as an alternative to petroleum-based plastics. Since 2015, the company's MI Division has researched reducing plastic use through this plant-derived material, which can be fully compostable depending on composition. Kinari uses an all-dry production process eliminating water, cutting energy consumption and CO₂ emissions. Applications range from electronics casings to automotive parts and building materials. Panasonic has demonstrated a complete lifecycle system for production, disposal, sorting, and recycling. The material can be mechanically recycled or biodegraded within nine months under industrial composting. Raw materials include plant waste like timber from forest thinning, post-consumer wood, straw, and seaweed. Panasonic aims to achieve cost parity with petroleum-based resins while offering a wood-like aesthetic without colorants. The company is also developing fully biodegradable versions with similar strength and performance.
