Announced: January 8, 2026

Deal Overview

Rubberize has developed a microwave-assisted devulcanization process that converts scrap tires into high-quality reclaimed rubber suitable for new tire manufacturing—something the industry has pursued for decades without success. Their process breaks sulfur cross-links in vulcanized rubber while preserving polymer chain length, yielding reclaimed rubber with 85% of virgin rubber properties. With 1 billion tires reaching end-of-life annually and only 40% recycled (mostly into low-value crumb rubber), Rubberize addresses a massive market gap.

Key Highlights

  • Reclaimed rubber retains 85% of virgin properties
  • 1 billion scrap tires generated annually worldwide
  • Pilot validation with major tire OEM
  • IP portfolio: 12 patents filed, 4 granted
