# Arduro

> Arduro is a Pennsylvania-based recovered materials company that uses a patented, low-temperature chemical devulcanization process to reclaim high-quality carbon black, rubber and silica from end-of-life tires and industrial rubber waste. Its process breaks the sulfur cross-links in vulcanized rubber without cutting the carbon-carbon polymer backbone, letting manufacturers replace virgin raw materials with recovered ones at comparable performance and lower carbon footprint. Its first commercial product, ELDARIX r1000 recovered carbon black, is PAH-compliant and 6PPD-free.

- **Founded:** 2019
- **Headquarters:** Bala Cynwyd, Pennsylvania, United States
- **Founders:** Ian Lowe (CEO), Patrick Kroeger (VP of Technology / Inventor), Dr. Gerold Willing (Co-inventor, University of Louisville Chemical Engineering Chair)
- **Team size:** 13 (approx. 11-20 range)
- **Products:** ELDARIX r1000 Recovered Carbon Black (rCB), Recovered Sustainable Rubber, Recovered Silica, Circularity as a Service (CAAS)
- **Notable:** Commercialized ELDARIX r1000 recovered carbon black that can replace virgin carbon black without loss of performance, Developed a patented chloramine-based devulcanization process operating below 100C without hazardous chemicals, Reports up to 75% lower carbon footprint vs. traditional rubber disposal (per LCA data)

## Products & services

- **ELDARIX r1000 Recovered Carbon Black (rCB)** — A sustainable, drop-in alternative to virgin carbon black with low ash content and small particle size; PAH-compliant and 6PPD-free, for tires, automotive parts, industrial rubber goods, inks, coatings and plastics. Available for sampling.
- **Recovered Sustainable Rubber** — Recovered rubber that Arduro states is molecularly identical to oil-produced rubber, targeting virgin-grade performance for tire manufacturing. In independent lab and scale-up trials.
- **Recovered Silica** — A reinforcing filler for green tire treads in electric vehicles, offering high tear strength, high modulus, fatigue resistance, low rolling resistance and superior wet traction. Initial testing completed.
- **Circularity as a Service (CAAS)** — A closed-loop service that lets rubber manufacturers send in their own rubber waste and receive recovered raw materials to reintegrate into new products, addressing Scope 3 emissions. Debuted October 2024.
