N-Fiber Oil Absorbent Pillow by Bignanotech – The Most Detailed Nano Solution Helping Enterprises Fully Meet the Requirements of Decision 04/2026/QĐ-TTg on Oil Spill Response
Effective from February 10, 2026, Decision 04/2026/QĐ-TTg issued by the Prime Minister officially came into force. This is currently the most important legal document governing oil spill response activities in Vietnam. The Decision completely replaces Decision 12/2021/QĐ-TTg and Decision 24/2025/QĐ-TTg, while introducing clearer and more specific regulations on spill classification, facility responsibilities, and equipment requirements.
According to Decision 04/2026/QĐ-TTg, oil spills are classified into three levels:
- Small spill: oil volume under 20 m³
- Medium spill: from 20 m³ to 500 m³
- Large spill: over 500 m³
The Decision particularly emphasizes the principle of “response close to the source,” requiring all facilities with potential risks (factories, oil depots, ports, petrol stations, vessels, aquaculture areas, etc.) to develop detailed response plans, equip adequate minimum materials, and control small-scale spills using on-site forces within the shortest possible time (typically a maximum of 2 hours).
In this context, the N-Fiber Oil Absorbent Pillow from Bignanotech is the most specific, practical, and easy-to-deploy nano solution that enables enterprises to fully meet the above requirements, especially in hard-to-reach locations where other products are often ineffective.
1. Detailed Technology and Structure of the N-Fiber Oil Absorbent Pillow
The N-Fiber Oil Absorbent Pillow is manufactured 100% at Bignanotech’s factory in Vietnam (Thai Binh), using high-grade polypropylene combined with Japanese nano technology transfer.
- Oil Absorbent Pillow core: Made from ultra-fine polypropylene fibers with a diameter of approximately 50–400 nm (much thinner than a human hair). The dense 3D capillary network structure significantly increases the contact surface area with oil, thereby enhancing both absorption speed and capacity.
- Outer cover: A combination of spunbond non-woven fabric and anti-tear polyester mesh. The outer layer allows rapid oil penetration into the core while securely retaining the absorbed oil inside, and protects the oil absorbent pillow from fraying or tearing even when fully saturated.
- Core properties:
- Completely hydrophobic (water absorption rate ≈ 0%). Selectively absorbs only hydrocarbons such as gasoline, diesel, lubricating oil, hydraulic oil, industrial grease, vegetable oil, etc.
- Extremely secure oil retention thanks to nano capillary force. Oil does not leak back even when the pillow is inverted, strongly compressed, or moved.
- Long-term buoyancy on water surfaces (over 72 hours even when fully saturated).
- Anti-static treatment, good heat resistance in the range of -40°C to +120°C (some sources record up to 150°C), suitable for use in flammable and explosive areas such as oil depots and chemical plants.
- Color: Pure white in its original state. When saturated with oil, the oil absorbent pillow gradually changes to the color of the oil (yellow, brown, or black), allowing users to easily monitor the saturation level by visual inspection.
2. Detailed and Specific Technical Specifications of Popular Product Codes
Based on official data and 2026 updates from Bignanotech:
| Product Code | Dimensions | Actual Absorption Capacity (Light Oil / Heavy Oil) | Approximate Weight | Packaging | Estimated Saturation Time | Priority Applications |
|---|---|---|---|---|---|---|
| N-FIBER W20 | 20 × 20 cm | 2.2–2.5 liters / 1.8–2.2 liters | 100–200 g | 32 pieces/carton | 1–3 minutes | Narrow gaps under pumps, small machine parts, small-scale garages |
| N-FIBER W23 | 20 × 30 cm | 3.2–4.2 liters / 2.5–3.5 liters | 150–300 g | 32 pieces/carton | 2–5 minutes | Most versatile: repair workshops, continuously leaking pipelines, under industrial machinery |
| N-FIBER W40 | 40 × 40 cm | approximately 8.0–8.8 liters | 350–450 g | 16 pieces/carton | 4–8 minutes | Settling tanks, small ports, medium-scale incidents |
| N-FIBER W45 | 40 × 50 cm | 9–10 liters / 7–9 liters | 400–500 g | 16 pieces/carton | 5–10 minutes | Large factories, water surfaces, rapid recovery of oil slicks |
- Average absorption ratio: 25–30 times its own weight. With light oils (diesel, gasoline) it can achieve higher ratios depending on actual conditions.
- Reusability: Hand or machine wringing can recover approximately 80–90% of the oil. The pillow can be reused 3–5 times (absorption capacity decreases by approximately 30% after each wringing). In some well-managed cases, it can be reused more times.
- Shelf life: Over 5 years when stored in a dry, cool place away from direct sunlight.
- Economic advantage: Domestically manufactured, therefore not subject to import duties, offering clearly competitive pricing compared to imported products from the USA, Australia, or Europe, with nationwide delivery within 1–3 days.
3. Specific Importance of the N-Fiber Oil Absorbent Pillow in Implementing Decision 04/2026/QĐ-TTg
Decision 04/2026 sets out very practical and mandatory requirements for enterprises. The N-Fiber Oil Absorbent Pillow directly supports the following key points:
- Rapid control of small spills under 20 m³ within a short time: The pillow can be placed or inserted directly at the leak point (under machines, pipe gaps, bilge compartments, drainage pipes). Absorption time of only 1–10 minutes enables enterprises to control the incident using on-site forces, fully meeting the requirement of “control within a maximum of 2 hours” for small spills.
- Response close to the oil spill source: The compact and flexible design allows immediate treatment at the point of origin, minimizing the spread of oil into the surrounding environment — fully aligned with the core principle of the Decision.
- Easy integration into response plans and minimum equipment lists: The product is lightweight, easy to store, and easy to inventory. Enterprises can combine N-Fiber oil absorbent pillows with N-Fiber oil absorbent pads, N-Fiber oil absorbent booms, and N-Fiber oil absorbent cotton to form a complete response kit that can be readily demonstrated during inspections by competent authorities at communal or provincial levels.
- Support for the “four on-the-spot” principle: No complex equipment or external specialized forces are required. Factory workers, port staff, or petrol station personnel can deploy it immediately.
- Reduction of legal risks and long-term costs: Having the oil absorbent pillows ready helps enterprises avoid being assessed as unprepared for oil spill response (which may lead to administrative fines or suspension of operations). At the same time, reusability and competitive pricing deliver significant savings on material costs.
4. Specific Applications by Environment and Spill Scale
- Mechanical, thermal power, electronics, and chemical plants: Place under presses, turbines, hydraulic pipelines, and CNC machines to handle continuous daily leaks.
- Seaports, oil depots, and vessels: Float on the water surface to collect oil slicks or insert into bilge water compartments and drainage pipes.
- Garages, petrol stations, and industrial zones: Control daily oil drips under vehicles, air compressors, and lifting equipment.
- Aquaculture: Protect ponds and lakes from oil originating from water pumps and backup generators.
- Flexible combination according to spill scale:
- Very small incidents: Only 1 or a few W20 or W23 pillows are needed.
- Small to medium incidents: Combine pillows + oil absorbent pads + oil absorbent booms to simultaneously treat narrow points and prevent spread.
5. Detailed Step-by-Step Usage Instructions
- Accurately identify the location and type of oil leak.
- Select the appropriate product code (W20/W23 for narrow gaps, W45 for larger areas).
- Place or insert directly at the leak point on land, or float freely on the water surface.
- Wait according to the saturation time of each code (1–10 minutes). Observe the color change to darker shades to confirm full saturation.
- Carefully lift the pillow out and wring the oil into a dedicated container (clean oil can be reused or recycled).
- Allow the pillow to air-dry in a well-ventilated place and reuse, or treat it as hazardous waste (code 19 02 08) when absorption capacity is exhausted.
Important safety notes: Always wear gloves and safety glasses. Do not burn used oil-saturated oil absorbent pillows directly. Store unused pillows in a dry place, away from sunlight and heat sources.
