View DetailsThe Democratic Republic of the Congo (DR Congo) holds a critical position in the global transition to clean energy, possessing over 70% of the world's cobalt reserves and substantial copper deposits. This booming mineral extraction sector, concentrated in provinces like Lualaba and Haut-Katanga, drives massive logistics and heavy machinery operations. Consequently, the region generates an unprecedented volume of Off-The-Road (OTR) tires and industrial rubber waste.
Traditionally, disposing of giant mining tires weighing up to several tons has been an environmental bottleneck for global mining companies operating in Kolwezi and Lubumbashi. Storing them poses severe fire hazards and biological risks. However, the introduction of continuous pyrolysis and recovered carbon black (rCB) refining systems transforms these liabilities into high-value raw materials.
By implementing localized pyrolysis refineries, Congolese enterprises can process OTR tires into heavy fuel oil—critical for supplying energy-intensive copper and cobalt smelters—and commercial-grade recovered carbon black, establishing a highly profitable closed-loop industrial economy within the country.
Convert heavy mining dump truck tires directly into industrial carbon black and pyrolysis oil, eliminating costly transportation and storage overheads.
Refined pyrolysis oil acts as an direct substitute for expensive imported diesel and heavy fuel oils in mining processing furnaces.
Raw carbon black obtained from standard tire pyrolysis contains inorganic residues and high ash content. The Huayuan Tech refining process utilizes chemical and mechanical upgrades to meet ASTM D8178 standard specifications.
Reduces the particle size of the raw pyrolysis char down to D97 < 10 microns. This ensures dispersion characteristics similar to virgin N330 / N550 carbon black grades.
Proprietary de-ashing mechanisms systematically lower sulfur, zinc, and ash compositions, preventing degradation in compounding performance.
Wet pelletization increases product bulk density, transforming fine, dusty powder into clean, transportable granules ready for pneumatic handling.
| Parameters | Raw Pyrolysis Char | Huayuan Refined rCB (ASTM Grade) | Typical Applications in DR Congo |
|---|---|---|---|
| Ash Content (%) | 15% - 20% | < 12% | Rubber Conveyor Belts, Footwear |
| Mean Particle Size | 30 - 50 μm | < 5 μm | Plastic Masterbatches, Printing Inks |
| Sulfur Content (%) | 2.0% - 2.5% | < 1.2% | Industrial Gaskets, Cable Sheathing |
| Carbon Purity (%) | 75% - 80% | > 88% | Reinforcement agent for Mining Hoses |
