Problem
The production of virgin carbon black relies on fossil fuels, consumes significant amounts of water, and releases substantial CO2 emissions, contributing to greenhouse gas emissions and environmental degradation. Traditional disposal methods for end-of-life tires result in substantial landfill waste and potential environmental hazards. The raw recovered carbon black (rCB) obtained from tire pyrolysis contains ash impurities that limit its direct use in high-value applications.
Solution
RCB Nanotechnologies provides a technology for recovering high-quality carbon black from end-of-life tires through a thermal and chemical process. The process involves pyrolyzing the tires to produce raw rCB, followed by thermal and wet-chemical treatments to remove ash and other impurities. The resulting recovered carbon black (rCB) has a high carbon content (+96%) and can be used as a sustainable alternative to virgin carbon black in various applications. The company's technology also enables the recovery of valuable byproducts such as silicates and zinc-based products from the separated ash, closing the loop in the tire industry's material cycles.
Target Audience
The primary target audience includes manufacturers in the tire, automotive, plastics, electronics, and dye industries seeking sustainable alternatives to virgin carbon black, as well as companies interested in high-quality recovered materials.
