The tire to tire circular economy constructs a closed-loop industrial system. Driven by advanced tire pyrolysis technology and guaranteed by standardized industry collaboration. The Tire to Tire closed-loop economy has evolved from a conceptual model into an industrial practice, becoming a core direction for global green tire manufacturing and solid waste recycling.
A leading global case demonstrates the effectiveness of this collaborative model: Pirelli, in partnership with Pyrum, BASF, and Synthos, established a European tire recycling closed-loop system. It utilizes recycled carbon black and refined pyrolysis oil from tires to produce new tires. Bridgestone and Versalis have also adopted similar industry collaboration models, achieving standardized reuse of recycled materials in tire production.
This cross-industry collaboration achieves specialized division of labor, forming a seamlessly integrated closed-loop industrial chain. Pyrolysis companies complete the decomposition and primary recycling of waste tires. Chemical companies complete deep purification and material modification. Tire manufacturers complete formula optimization and finished product production.
Core Value of the Tire to Tire Circular Economy
Its core definition is the recovery of high-purity, high-performance raw materials from waste tires and their use in the production of new tires. This achieves the unlimited recycling of materials without compromising quality. Key recyclable materials include recycled carbon black (rCB), refined tire pyrolysis oil (TPO), recycled steel wire, and synthetic rubber monomers.
Recycled carbon black (rCB) can replace virgin carbon black in new tire production. Tire pyrolysis oil (TPO) can be refined into oils used in the production of chemicals required for synthetic rubber.
This tire-to-tire circular model offers both environmental and economic value.
From an ecological perspective, it eliminates pollution from landfills and incineration, reduces over-reliance on natural rubber and fossil fuels, and lowers greenhouse gas emissions throughout the tire's lifecycle.
From an economic perspective, it stabilizes the raw material supply for the recycling industry, reduces production costs for tire companies, and builds a sustainable green supply chain, fully aligning with global carbon neutrality and circular economy policies.
Tire Circular Economy Full-Chain Implementation Strategy
Standardized waste tire collection and pre-sorting systems are the first step in this closed-loop cycle. Tires of different brands, lifespans, and formulations are categorized and grouped to ensure consistency in raw material performance, providing a reliable raw material foundation for subsequent high-precision pyrolysis recycling.
To achieve large-scale production for a tire circular economy, promoting fully continuous pyrolysis plant is crucial. Optimizing temperature control and residence time can significantly improve the yield and stability of pyrolysis oil and recycled carbon black. Combined with deep desulfurization, deashing, and molecular refining processes, recycled materials can be further upgraded to tire-grade standards.
Tire recycling cannot be accomplished by a single company. It requires deep collaboration between tire manufacturers, pyrolysis plant manufacturers, and chemical refining companies.
