In an era where sustainable energy and resource efficiency are paramount, the demand for innovative solutions to environmental challenges is growing rapidly. Waste oil, a significant pollutant if improperly disposed of, also represents a valuable untapped energy source. Transforming this waste into usable fuel not only addresses a critical environmental concern but also offers a compelling economic advantage.

DOING Holdings, a leading manufacturer of waste oil distillation equipment, provides advanced solutions designed to convert various types of waste oil (waste engine oil, used motor oil, oily sludge, mazut, tire plastic pyrolysis oil, old black oil, etc.) into high-quality non-standard diesel fuels.

The Fuel Produced: "Non-Standard Diesel"

The primary output of DOING's waste oil distillation process is commonly known as "non-standard diesel" or industrial fuel oil. This fuel possesses excellent characteristics, making it highly valuable for specific applications.

Key Characteristics of Non-Standard Diesel:

High Calorific Value: With calorific value approximately 44MJ/kg, meaning it releases a significant amount of heat upon combustion, making it an efficient fuel.

Excellent Combustion Performance: The fuel has high energy content and consistently, , making it a solid choice for for industrial applications.

Distinction from Commercial Diesel:

It's important to note that DOING's non-standard diesel does not typically meet the stringent specifications of commercial automotive diesel fuel, such as Euro V or Euro VI standards. These commercial standards dictate extremely low sulfur content, precise cetane numbers, and specific additive packages required for modern automotive engines to meet emissions regulations and ensure engine longevity.

Non-standard diesel from DOING's process retains more natural properties from the source oil, leading to higher sulfur content and potential impurities. While this makes it unsuitable for standard road vehicles, it performs well in less demanding setups where fuel quality standards are more relaxed.

For industrial applications where these ultra-low sulfur and specific additive requirements are not critical, DOING's non-standard diesel performs exceptionally well and offers a cost-effective alternative.

AspectNon-Standard Diesel (from Waste Oil Distillation)Commercial Diesel (On-Road Standard)
Sulfur ContentSulfur Content High (up to 500 ppm or more)Ultra-low (≤15 ppm)
Cetane NumberLower (typically<40)High (45-55)
Calorific Value~44 MJ/kg~42-45 MJ/kg
Purity/ImpuritiesHigher aromatics, metals; potential depositsHighly refined; minimal impurities 
AdditivesMinimal or noneIncludes detergents, lubricity enhancers
Cost20-30% cheaperHigher due to refining and taxes 
ApplicationsIndustrial heating, generators, off-road/agricultureOn-road vehicles, modern engines
Regulatory SuitabilityOff-road/industrial only; not for public roadsRoad-legal; engine warranty compliant

Key uses of DOING's Non-Standard Diesel

Industrial Heating: The non-standard diesel is an ideal direct heat source for various industrial heating applications. This fuel is commonly used in furnaces and boilers for steady heat generation. For example, factories, cement plants, and steel mills can use it to fuel boilers, keeping production lines running replacing the commercial diesel. It's particularly effective in textile or food processing facilities that need consistent, affordable heating.

Power Generation: Many factories and remote areas rely on generators for power. The non-standard diesel produced by DOING distillation units is perfectly suited for industrial generator sets. It provides a reliable and consistent power source at a cost significantly lower than purchasing new commercial diesel, making it a popular choice for manufacturing plants to reduce operating expenses.

Agricultural Equipment: For agricultural machinery that does not require ultra-low sulfur automotive diesel – particularly older models or equipment with less sensitive engines – this recycled fuel offers a viable and economical option.

Marine Fuel (with specific conditions): In certain applications, after further blending or processing, this non-standard diesel can be utilized as a cost-effective fuel component for marine boilers or low-speed marine engines. This helps shipping companies manage and control their substantial fuel costs.

Non-standard diesel uses

Environmental and Economic Benefits

Converting waste oil through recycling and distillation into usable non-standard diesel fuel is not only an environmentally friendly and sustainable waste solution, but also an economic decision.

Environmental Benefits:

Instead of being improperly dumped into soil or water, where it causes severe pollution and environmental harm, waste oil is transformed into a valuable energy source. Burning recycled non-standard diesel as fuel can reduce the extraction of primary fossil fuels to a certain extent, thus reducing the overall environmental footprint.

Economic Benefits:

Businesses gain a dual advantage: solving a costly waste disposal problem and securing a low-cost, reliable energy supply. This sustainable approach reduces reliance on fluctuating fossil fuel markets, enhances operational efficiency, and significantly boosts the bottom line. It embodies the principles of a circular economy, turning a waste stream into a revenue stream.
