Re-refined fuel oil from used lubricating oil and industrial waste streams. A cost-effective, environmentally-responsible alternative to virgin industrial diesel for boilers, furnaces, and heavy stationary applications.
Black diesel — also known as recycled diesel, re-refined fuel oil, or used oil fuel — is produced by collecting used lubricating oil (from vehicle oil changes, industrial machinery, hydraulic systems), processing it to remove contaminants (water, heavy metals, solids, and degraded additives), and producing a fuel-grade product suitable for industrial combustion.
At Hibernia Diesel, our black diesel program sources used oil from licensed collectors, processes it through approved re-refining facilities, and supplies the resulting fuel to industrial consumers. Every litre of black diesel used is one litre of virgin diesel not burned — and one litre of used oil responsibly managed rather than improperly disposed.
100% Legal & Documented: Our black diesel is a legitimate, documented, processed recycled product from licensed facilities — fully compliant with UAE regulations. Chain of custody maintained from waste generator to end-user.
The UAE generates millions of litres of used lubricating oil annually — from vehicle servicing, industrial machinery, marine operations, and power generation. Improper disposal contaminates soil, groundwater, and marine environments. 1 litre of used oil can contaminate 1 million litres of fresh water.
Re-refining addresses multiple challenges simultaneously: used oil diverted from dumping, virgin fuel demand reduced, 40–70% lower lifecycle GHG emissions, and processing in controlled facilities with emission controls — far cleaner than informal burning.
Using recycled fuel can be reported as part of corporate sustainability initiatives, waste reduction targets, and circular economy commitments. We provide documentation of the fuel's recycled origin for your ESG reporting.
We source only from licensed, audited collectors and process through approved facilities with environmental permits. Full chain of custody documentation from waste generator to end-user. We do not engage in the informal, unregulated used oil trade.
| Parameter | Typical Range |
|---|---|
| Appearance | Dark amber to black (color from residual carbon and additives) |
| Density at 15°C | 860–920 kg/m³ |
| Sulfur Content | 0.1–1.0% m/m (1,000–10,000 ppm) — lower sulfur available on request |
| Flash Point | ≥ 60°C (safe for industrial storage and handling) |
| Kinematic Viscosity at 40°C | 5.0–20.0 mm²/s (varies by grade) |
| Water Content | ≤ 0.5% v/v (processed to remove free and emulsified water) |
| Sediment | ≤ 0.1% m/m (solids removed during processing) |
| Ash Content | ≤ 0.05% m/m |
| Calorific Value (Gross) | 42–44 MJ/kg (~90–95% of virgin diesel energy content) |
| Heavy Metals (Pb, Cd, Cr, As, etc.) | Within regulatory limits for industrial fuel — heavy metal analysis provided in COA for every batch |
| Pour Point | -10°C to +10°C (varies by grade and processing) |
| Reference Standard | Comparable to ASTM D396 Grade No. 4, 5, or 6 depending on degree of re-refining |
* Actual specifications depend on the used oil feedstock and re-refining process. We provide a batch-specific COA with every delivery including heavy metal analysis. Please discuss your equipment's fuel requirements with our technical team.
Black diesel pricing is partially decoupled from crude oil markets, providing some price stability compared to virgin diesel.
If your company generates used oil as part of operations, supplying it to our re-refining program may reduce your hazardous waste disposal costs.
Reduce your fuel costs and your environmental footprint. Tell us your boiler/heating fuel consumption and we'll provide a quotation for black diesel supply.
