N-FIBER PULP2 and PULP5 Oil Absorbent Cotton from Bignanotech: Vietnam’s Leading Solution for Oil Spill Response and Environmental Protection in 2025
In the context of Vietnam’s robust industrial growth in 2025, oil spills and leaks of lubricants from machinery, vessels, storage tanks, offshore platforms, or factories remain a serious threat to water, soil, and ecosystems. Under strict regulations such as Decree 45/2022/NĐ-CP on administrative penalties for environmental violations, businesses bear significant responsibility for rapid response. The N-FIBER oil absorbent cotton PULP2 (packaged in 2kg boxes) and PULP5 (packaged in 5kg boxes) products from BIG Nano Technology Co., Ltd. (Bignanotech) – the only manufacturer in Vietnam applying nano technology to oil absorbent materials – stand out as the optimal solution, delivering superior performance and serving as a perfect alternative to imported brands like 3M or Spilfyter.
This article provides the most detailed and accurate information updated to late 2025 from Bignanotech’s official sources: production technology, technical specifications, diverse applications, superior benefits, usage instructions, and why Bignanotech is the top choice for Vietnamese enterprises.
1. Bignanotech – The Sole Manufacturer in Vietnam with Advanced Nano Technology
Established in 2019, Bignanotech is a Vietnamese pioneer in researching and applying Japanese nano melt-blown technology to produce oil and chemical absorbent materials. It is the only company in Vietnam manufacturing industrial-scale oil absorbents using nano technology, with a modern factory at Phuong La Industrial Cluster, Phuong La Village, Thai Phuong Commune, Hung Ha District, Thai Binh Province. The representative office is located in Hanoi (The Manor, My Dinh).
Key advantages of Bignanotech:
- Sole domestic manufacturer: Ensures complete documentation (CO, CQ, ISO quality certifications, environmental testing from the Ministry of Natural Resources and Environment), facilitating legal procedures and environmental reporting for businesses.
- Custom production: Flexible customization of fiber density, anti-static versions, or specialized chemical variants; packaging tailored to needs (currently, N-Fiber oil absorbent cotton products are conveniently boxed in 2kg as PULP2 and 5kg as PULP5).
- International quality commitment: Products meet Japanese and European standards, eco-friendly, widely used in Vietnam, and exported to Japan in 2025.
The N-FIBER brand encompasses a full range: oil absorbent pads, containment booms, pillows, rolls, and loose pulp – forming a comprehensive ecosystem for oil spill response.
2. Nano Melt-Blown Technology – The Superior Foundation of N-FIBER PULP2 and PULP5
N-FIBER Oil absorbent Cotton PULP2 and PULP5 are made from 100% virgin polypropylene through the nano melt-blown process: molten material is extruded into ultra-fine fibers (diameter <100nm), creating a dense capillary network with millions of contact points.
Advantages of nano technology:
- Selective absorption: Exclusively absorbs oil and hydrocarbons (diesel, hydraulic oil, machine lubricants, organic solvents, oil-based paints…), completely hydrophobic – repels water even after prolonged immersion.
- Ultra-fast absorption rate: 5-10 times faster than standard polypropylene products due to uniform micro-pores.
- Strong oil retention: No dripping even when saturated, minimizing secondary contamination.
- Excellent buoyancy: Remains afloat on water long-term for easy recovery.
- High durability: Does not disintegrate, withstands waves, wind, rain, sunlight, and mild acid/alkaline environments.
Compared to natural cellulose loose absorbents or non-nano imported products, the N-FIBER Oil absorbent cotton PULP series is lighter, faster-absorbing, more reusable, and environmentally superior.

4. Most Versatile Applications of N-FIBER PULP2 and PULP5 Oil Absorbent Cotton
Cotton is the most flexible product in the N-FIBER line, excelling in hard-to-reach areas where pads, pillows, or booms are ineffective:
- On water surfaces: Absorbs oil slicks on rivers, lakes, seas, aquaculture ponds; handles oil/water emulsions in oil & gas and port operations (PULP5 ideal for large-scale).
- Narrow and complex areas: Scatter into drains, machine crevices, rocky shores, bushes, rice fields, mangrove forests (PULP2 convenient for small, portable needs).
- Daily industrial use: Cleans leaks on factory floors, under CNC machines, warehouses; maintains hydraulic and lubricant oils in mechanical, automotive, and food production.
- Large-scale emergency response: Integrates into spill kits with containment booms and pads for vessel, tanker, or offshore platform spills.
- Sensitive environments: Protected ecosystems, beaches – hydrophobic nature avoids impacting aquatic life.
Numerous oil & gas enterprises, ports, and major manufacturing facilities in Vietnam trust the N-FIBER Oil absorbent cotton PULP series to maintain workplace safety and avoid environmental penalties.
5. Superior Benefits of Choosing Oil Absorbent Cotton from Bignanotech
- Optimal response efficiency: Fast absorption, high capacity, significantly reduces remediation time and labor (PULP5 for large spills, PULP2 flexible for minor incidents).
- Sustainable environmental protection: No secondary toxins, supports oil recovery and recycling, minimizes soil and water pollution.
- Absolute safety: Lightweight, easy handling, no additional slips; special anti-static versions for fuel storage and refineries.
- Flexibility and customization: As Vietnam’s sole manufacturer, Bignanotech offers tailored production (density, features, packaging) for rapid enterprise needs.

6. Detailed Usage Instructions and Post-Use Handling
- Application process: Evenly scatter loose pulp over the spill area (quantity based on oil thickness and box size 2kg/5kg). Wait 1-5 minutes for full absorption. Collect with shovel, net, or specialized vacuum.
- Oil recovery: Use mechanical pressing, centrifugation, or manual wringing for reuse, enhancing economics.
- Waste disposal: Controlled high-temperature incineration or handover to licensed hazardous waste processors.
- Safety notes: Always wear PPE (gloves, goggles, mask) for large incidents. Store in dry areas away from open flame.
