Waste Tire Recycling & Resource Recovery · Water Healer
01 / Tire Recycling Value

Turning Every Waste Tire
Back Into the Value Chain

Water Healer's continuous pyrolysis — multi-stage process control, precise temperature regulation and a self-sustaining reaction — converts waste tires (end-of-life tires, ELTs) into recovered carbon black, pyrolysis oil, fuel gas and steel wire: full-component resource recovery, with every output stream returned to industrial use.

02 / Carbon Black Value

From End-of-Life Tires,
Back Into New Tires

Pyrolysis char is upgraded into recovered carbon black (rCB), which can substitute for virgin carbon black in tires and rubber products. In 2023, less than 1% of tire-grade carbon black was sourced from end-of-life tires — that supply gap is the market opportunity.

03 / Pyrolysis Oil Value

Pyrolysis Oil: An Urban Oil Field
Yield Above 50%

Oil yield reaches 52.4%, against a 40–46% industry mainstream — an extra 60–120 kg of oil per tonne of feedstock. Each tonne can be directed to two applications: fuel for stable demand, or chemical feedstock for higher-value use.

Measured Total Yield
52.4%

Oil-1 48.08% + Oil-2 4.32%

Industry Mainstream

A 6–12 percentage-point advantage over the industry mainstream

Extra Yield per Tonne

Styrene, limonene and BTX extraction: the highest unit value, feeding chemical feedstock streams
Middle fractionStable revenue
Substitutes for heavy fuel oil in industrial boilers; also usable as a low-sulfur marine blendstock
Heavy fractionClosed loop
Substitutes carbon black feedstock oil (CBFS) for our own furnace black line, with surplus sold to third parties
Sales Outlets and Premium over Fuel Grade

Premium ranges are indicative; actual prices depend on market conditions and long-term contracts.

04 / Pyrolysis Gas Value

Non-Condensable Gas Reuse:
The Logic of Energy Self-Sufficiency

Non-condensable gas from pyrolysis is recovered and used for process heat, making the plant energy self-sufficient in normal operation. This lowers operating cost and makes the resulting carbon reductions a net gain.

Unit energy reduction >25%
Value 1 · Lower Cost

Self-supplied energy removes most purchased fuel; savings grow with capacity.

Value 2 · Stable Operation

Staged grading, precise temperature control and a self-sustained reaction enable continuous runs of 60+ days.

Value 3 · Net Reduction

Plant emissions are accounted for first, so the remaining reductions are net and claimable.

05 / Carbon Reduction Value

Turning Carbon From a Cost Line
Into a Revenue Line

As carbon constraints tighten, the choice of treatment route determines the carbon bill. Per tonne of waste tires, pyrolysis delivers the largest emission reduction of any treatment route — reportable in ESG disclosure and developable into carbon credit assets.

CO₂ Reduction per Tonne of Waste Tires, by Treatment Route (tCO₂e/t)
Pyrolysis 1.1 t
Crumb rubber 0.5 t
Retreading 0.45 t
Reclaimed rubber 0.37 t

Notes: (1) Full-component shares are indicative mass-balance ranges (steel wire 15–20%, pyrolysis oil 39–42%, char 32–34%, gas 8–10%); measured data from on-site weighbridge tests (10,400 kg feed, 97.85% accounted, 2.15% loss and measurement error). (2) Per-tonne reductions follow the ISO 14040/14044 substitution method with literature-based substitution factors; full-scope ≈2.4–2.5 tCO₂e/t and 1.1 tCO₂e/t is the conservative figure currently cited. Figures are internal estimates pending third-party verification (ISO 14064 / GHG Protocol) before external use. (3) Premium and carbon-asset ranges are order-of-magnitude estimates for commercial positioning, not revenue commitments; actual values depend on market prices, long-term contracts and carbon market rules.
