N-Fiber Oil absorbent cotton from Bignanotech: Breakthrough Vietnamese Nano Solution, Perfectly Compliant with Decision 04/2026/QĐ-TTg
In the context of increasingly stringent legal regulations on oil spill response, Decision 04/2026/QĐ-TTg (issued on January 23, 2026, effective from February 10, 2026) has replaced the old regulations (12/2021 and 24/2025), marking an important shift in environmental incident prevention and response. This Decision clearly classifies incidents by scale: minor (<20m³), medium (20-500m³), and major (>500m³); it specifies detailed requirements for minimum equipment and supplies, response plans at facility, provincial, and national levels. Businesses that fail to prepare adequately face heavy fines, operational suspension, or enormous environmental compensation liabilities.
N-Fiber Oil absorbent cotton from Bignanotech is the “superhero weapon” of Vietnamese nano technology, helping you take proactive, cost-effective action and easily demonstrate full legal compliance immediately.

What is N-Fiber Oil absorbent cotton? Advanced Technology from Japan – Produced in Vietnam
N-Fiber Oil absorbent cotton is an oil absorbent cotton product made from 100% high-quality polypropylene, applying Japanese nano technology. Bignanotech – Big Nano Technology Co., Ltd. – is the pioneer in bringing this technology to Vietnam, creating a high-quality Vietnamese product line with tax incentives, competitive pricing, and stable supply.
Unlike conventional absorbent cotton, N-Fiber Oil absorbent cotton features an ultra-fine nano fiber structure that creates enormous surface contact area, enabling extremely fast and highly selective absorption.

Outstanding Technical Features – Detailed & Superior
- Absorbs only oil, absolutely does not absorb water: Strong hydrophobicity, floats on water even when fully saturated with oil. Perfect for both onshore incidents (factory floors, garages) and water surface incidents (seaports, canals, rivers, seas). Does not sink under waves, heavy rain, or currents.
- Superb absorption capacity: Absorbs 14-50 times its own weight depending on oil type (crude oil, DO, gasoline, lubricants, machine oil…). For example: 1kg of N-Fiber absorbs approximately 14-50 liters of oil. The PULP5 bucket (5kg) can handle hundreds of liters in just 3-10 minutes.
- Lightning-fast absorption speed: Thanks to the nano fibers, it absorbs many times faster than traditional products. Easily visible to the naked eye: fibers change from white to dark color when fully saturated.
- Easy collection & reuse: Floats on water, easily retrieved with nets, vacuum, or by hand. Can be wrung dry and reused 3-5 times (efficiency gradually decreases by about 30% each time). Recovered oil can be recycled, minimizing secondary pollution.
- High safety: Anti-static, withstands temperatures from -20°C to +80°C, chemical resistant, leaves no toxic residue. Especially suitable for explosive environments such as fuel depots and factories.
- Flexible design: Loose fiber form, easily spread into tight spaces – drains, field crevices, muddy areas, rock gaps, grass patches – where traditional absorbent pads or booms are difficult to reach.
- Sustainable & Economical: Vietnamese-made → 30-50% cheaper than imported products from the US or Australia; proactive supply, no risk of disruption.

Decision 04/2026/QĐ-TTg: N-Fiber Oil absorbent cotton Helps Businesses “Sleep Soundly”
The new Decision requires all facilities with oil spill risks (fuel depots, seaports, factories, drilling rigs…) to develop detailed response plans, equip appropriate materials, and conduct regular drills. N-Fiber Oil absorbent cotton perfectly meets the minimum equipment list, helping you:
- Quickly control minor incidents and support medium-level incidents.
- Reduce response time and limit spread.
- Easily prove compliance during inspections.
- Save costs compared to chemical dispersants or traditional methods (savings of 60-70%).

Real-World Applications Across All Industries
- Oil & Gas and Seaports: Recovers up to 98% of spilled oil on water surfaces, protecting marine ecosystems.
- Manufacturing Plants & Warehouses: Keep ready in machinery areas and storage tanks for daily leak handling.
- Auto Garages and Repair Workshops: Quickly clean up spilled lubricants without leaving stains.
- Agriculture & Environment: Protects canals, ditches, and fields from machinery oil.
- Complex Terrains: Urban drains, industrial zones, beaches.

Detailed Usage Instructions (Only 4 Simple Steps)
- Assessment & Preparation: Determine the spill level, area, and oil type. Wear gloves and safety glasses.
- Spread N-Fiber: Spread an even thin layer (approximately 1kg for 5-10m² depending on oil thickness). Use more in thicker areas.
- Wait & Observe: 3-10 minutes. Fibers change color → fully saturated. Flip if necessary.
- Collection & Disposal: Retrieve with nets, wring dry to recover recyclable oil. Reuse the fiber or dispose of as hazardous waste according to regulations.
Note: Store in a dry place, away from direct fire. Once fully saturated, dispose of according to hazardous waste regulations.
