End-of-Life Tires to Carbon Black
Magister Operis presents a worldwide-patented circular waste-to-value opportunity to collateral providers and qualified investors: a sealed, low-temperature process that converts end-of-life tires into industrial-grade carbon black and related products, recovering the material value that combustion destroys. The technology is proven at full scale, modular, and ready for funding and implementation.
Magister Operis works alongside the technology principals and an affiliated institution that owns the intellectual property and provides governance, economic modelling, and capital-mobilization support.
The opportunity
End-of-life tires are one of the world’s largest untapped material resources. More than four billion already sit in stockpiles, with over a billion added every year. Roughly two in five are landfilled or dumped, and most of the remainder are burned as tire-derived fuel — a practice that destroys the material value of the tire while generating emissions. Only an estimated 20–30% undergoes genuine material recovery. Stockpiled tires also carry real liabilities: catastrophic fire risk, heavy-metal and toxin leaching into soil and groundwater, and microplastic pollution.
At the same time, demand for high-grade carbon black is rising across rubber, plastics, pigments, and coatings, while supply remains tied to expensive, oil-derived feedstocks. Carbon black recovered from tires closes that gap — turning a waste liability into a commodity-grade asset.
| Output market | Scale | Why it matters |
|---|---|---|
| Carbon black | ~15 million tonnes a year | Demand rising across rubber, plastics, pigments and coatings; supply still tied to oil-derived feedstocks. |
| Industrial solvents & diluents | Multi-billion-litre markets | High-aromatic, BTX-rich streams serve refining, chemical-feedstock and diluent-blending demand. |
| Renewable gas | Captured on-site | Powers the process itself, removing external fuel and supporting heat, hydrogen and fuel-cell uses. |
How it works
The process is a sealed, low-temperature thermal-mechanical depolymerization carried out under vacuum. Unlike conventional pyrolysis — which cracks material at 400–800°C and downgrades it to char and fuel oil — this approach separates the tire into its valuable fractions without combustion, preserving their commercial grade. Nothing is burned, and nothing is wasted.
Feedstock is end-of-life tire crumb (0.25″–0.75″). Each modular unit runs continuously, 24/7, and becomes self-powered after a one-time grid start-up. The technology has accumulated more than 10,000 hours of full-scale operation across feedstocks.
| Output | Indicative specification | Commercial result |
|---|---|---|
| Carbon black | ASTM N330 grade · ~29 nm particle size · ~85 mg/kg iodine absorption | Independently validated as a direct N330 replacement; sold into rubber and industrial markets |
| Aromatic diluent / solvent | 85–95% aromatic content · 40–200°C boiling range · BTX plus naturally occurring d-limonene | Sold as industrial solvent, chemical feedstock and refining diluent |
| Renewable syngas | ~1,600 BTU/scf | Captured to power the unit; surplus suitable for heat, hydrogen and fuel cells |
| Waste streams | None | Every fraction is recovered and either sold or used |
Three commodity-grade revenue streams
Every output is a market-ready material, not a downgraded by-product. Independent laboratory analysis confirms performance consistent with virgin-produced equivalents.
N330 carbon black. Recovered carbon black validated to ASTM N330 — confirmed in independent rubber testing to deliver comparable cure behaviour, strong tensile and elongation values, and equal or better abrasion resistance than the N330 control. It serves as a high-ratio replacement in tread rubber, belts, hoses and mechanical rubber goods, with further markets in plastics, pigments, inks and coatings.
High-aromatic diluent and solvent. A multi-component aromatic stream (85–95% aromatic content) carrying a BTX signature and naturally occurring d-limonene. It is sold as an industrial solvent, a chemical feedstock, a blending diluent and a refining feedstock.
Renewable syngas. Non-condensable gas captured during processing powers the unit itself, creating a self-sustaining closed loop that needs no external fuel after start-up. Surplus supports industrial heating, hydrogen production and fuel-cell applications.
Why it suits collateral providers and investors
The model is built on product value, not subsidies. A single waste feedstock yields multiple independent revenue lines, and every unit is modular, on-site and self-powered.
| Feedstock secured | ~17,500 tonnes of end-of-life tire feedstock processed per unit each year — roughly 875,000 tires diverted from disposal |
|---|---|
| Revenue lines | Carbon black, aromatic diluent/solvent, and carbon credits — not dependent on any single market |
| Capital security | The investor’s capital is collateral-protected: an affiliated institution brings forward top-rated securities — at least three times the investment value — as security held against the investor’s cash. |
| Deployment | Modular and scalable — capacity is added as demand grows; ~48 tonnes processed per unit per day |
| ESG & environment | Zero waste streams · ~21,900 net tonnes of CO₂e avoided per unit each year · ~18,000 carbon credits generated · equivalent to ~4,760 cars off the road annually |
