N-Fiber Oil Absorbent Roll by Bignanotech: The Detailed “Green Carpet” Solution Helping Businesses Proactively Control Oil Spills and Fully Comply with Decision 04/2026/QD-TTg
From February 10, 2026, Decision 04/2026/QD-TTg of the Prime Minister officially took effect, completely replacing Decision 12/2021/QD-TTg and Decision 24/2025/QD-TTg. The new regulation tightens requirements for oil spill response preparedness under the “4 on-site” principle, clearly specifying the minimum list of equipment and materials for each level (facility, provincial, and national) and each type of facility (fuel depots, ports, retail stations, factories, etc.).
In particular, facilities on land, rivers, and coastal areas must contain oil spills within a maximum of 02 hours for incidents under 20 m³ using on-site forces and materials. This is no longer a recommendation but a legal obligation. Businesses lacking specialized materials risk administrative penalties, operational suspension, and very high environmental remediation costs.
In this context, the N-Fiber Oil Absorbent Roll from Bignanotech has become the most practical, flexible, and highly effective choice available today — meeting legal requirements while directly addressing the real concerns of businesses: response speed, operating costs, occupational safety, and environmental protection.
1. Japanese Nano Technology – Superior Selective Absorption Mechanism
The N-Fiber Oil Absorbent Roll is 100% manufactured in Vietnam by Bignanotech, applying Japanese Melt-blown nano-fiber technology on a base of 100% virgin polypropylene.
The ultra-fine fiber structure (diameter under 30–100 nm) creates a 3D capillary network with high void ratio, delivering key characteristics:
- Absolute selective absorption: Absorbs only oil and hydrocarbon-based substances (gasoline, diesel DO, machine oil, hydraulic oil, industrial grease, oil-based solvents, etc.).
- Completely hydrophobic: Does not absorb water even when left on water surfaces for long periods, remains buoyant, and continues to absorb oil effectively.
- No fiber shedding, no oil re-release: Oil is tightly locked inside the fiber structure even when fully saturated.
- Evenly spaced small surface perforations: Allow oil to penetrate faster than conventional polypropylene materials.
- Easy color indication: Starts white and gradually darkens (to gray–black) when saturated, enabling users to monitor and replace it in time.
Actual absorption capacity reaches approximately 15–30 times its own weight, depending on the type of oil and usage conditions. The product is anti-static, reducing fire and explosion risks in fuel storage and chemical areas.
2. Detailed Technical Specifications of the Two Most Popular Models
| Specification | N-FIBER R504 | N-FIBER R508 |

| Absorption capacity (estimated) | Up to ~160 liters of oil per roll | Up to ~320 liters of oil per roll |
| Dry weight | ~6.5 kg/roll | ~12–14 kg/roll |
| Material | 100% Polypropylene + Japanese nano technology | 100% Polypropylene + Japanese nano technology |
| Color | White (changes color when saturated) | White (changes color when saturated) |
| Packaging | 1 roll per box | 1 roll per box |
| Reusability | 3–5 times (absorbency decreases ~30% after each wringing) | 3–5 times (absorbency decreases ~30% after each wringing) |
| Main applications | Medium-to-small factories, walkways, under machinery, daily leaks | Large spills, seaports, rivers, wide areas, emergency response |
The product can be easily cut with ordinary scissors to any required length without reducing absorption performance.
3. Practical Applications Of N-Fiber Oil Absorbent Roll – Addressing the Exact Needs of Different Business Types
In factories, production workshops, and garages:
Cut into mats placed under machinery, engines, hydraulic pumps, and gearboxes to proactively prevent daily oil drips. Lay as safe walkways in oily areas to reduce slip hazards and floor contamination.
At fuel depots, retail stations, river and seaports:
Deploy on water surfaces to recover thin oil sheens, create temporary response corridors, or combine with N-Fiber containment booms to quickly control incidents within the 02-hour timeframe required by regulations.
In equipment maintenance and cleaning:
Use to wipe oil from machinery surfaces and metal parts without scratching or leaving fiber residue.
Outdoor incident response:
Thanks to its hydrophobic and buoyant properties, the N-Fiber oil absorbent roll performs effectively on rivers, canals, rainwater surfaces, and flooded areas.
4. Specific Benefits for Businesses under Decision 04/2026
- Clear legal compliance: The product belongs to the specialized absorbent materials group and can be easily included in the minimum equipment list of facility-level response plans. It helps businesses demonstrate on-site response capability as required to “contain within 02 hours.”
- Real cost savings: More competitive pricing than imported products (no import tax, stable domestic supply). Reusability of 3–5 times significantly reduces average cost per incident.
- Faster response speed: Rapid absorption limits oil spread, reduces machine downtime, and lowers environmental remediation costs.
- Improved occupational safety: Creates a dry, clean surface and reduces slip-and-fall accident risks.
- Environmental protection and corporate image: Minimizes oil released into the environment, aligning with sustainable development trends and ISO 14001 standards.
5. Detailed Usage Instructions – Only 4 Simple Steps
- Preparation: Remove the roll from the box and cut to the required length (can be cut into small sheets of 40×40 cm, 50×50 cm, or tens of meters depending on the situation).
- Deployment: Lay directly onto the oil spill, under leak points, create walkways, or float on water surfaces.
- Monitoring: Observe the color change to darker shades — a sign of saturation. Absorption time typically ranges from a few seconds to several minutes depending on oil viscosity.
- Collection & disposal: Wring out the oil (if reusing), then send the saturated product to a hazardous waste collection point according to regulations. Keep away from heat sources or open flames.
Expert tip: Combine the N-Fiber oil absorbent roll with oil absorbent booms and N-Fiber absorbent pillows to create a complete response kit that better meets the requirements of the appendices attached to Decision 04/2026.
Conclusion: Prepare Correctly – Stay Truly Safe – Ensure Solid Compliance
The N-Fiber Oil Absorbent Roll is not just a consumable material. It is a practical tool that helps businesses proactively control oil spill risks, fully meet the “4 on-site” spirit of Decision 04/2026/QD-TTg, while optimizing costs and protecting the environment.
At a time when regulatory authorities are intensifying inspections of the new regulation’s implementation, equipping a Vietnamese solution of international quality like N-Fiber is the smartest, most cost-effective, and sustainable step.
