In an era where oil spill incidents are increasingly frequent due to industrial activities, maritime transport, and natural disasters, the demand for high-quality oil absorbent materials has never been more critical. Bignanotech (Big Nano Technology Company Limited), established on May 15, 2019, in Thai Binh, Vietnam, is a pioneering company in researching and manufacturing oil absorbent products using proprietary nano technology.
With its flagship product lines N-Fiber (tailored for the Vietnamese market) and ECOSAS (optimized for Japan), Bignanotech not only meets domestic needs but also successfully exports to international markets, notably Japan through its strategic partner ASPiA JAPAN Co., Ltd.. These products have been featured in prestigious Japanese media such as ASPiA Japan and JPRSI documents, earning the “Outstanding Environmental Contribution” award from Japan’s Ministry of Agriculture, Forestry, and Fisheries on October 12, 2024, for their exceptional performance and environmental commitment. Let’s dive into the success story of Bignanotech and why its products are the top choice for oil spill response.
About Bignanotech: Breakthrough Nano Technology “Made in Vietnam”
Bignanotech is a Vietnamese leader in producing oil absorbent and chemical materials, with its main office at Building A The Manor Me Tri, My Dinh 1 Ward, Nam Tu Liem District, Hanoi. The manufacturing factory is located in Tien La Commune, Hung Yen Province, Vietnam (previously in Phuong La Hamlet, Thai Phuong Commune, Hung Ha District, Thai Binh Province), spanning 5,000m², where a proprietary process using nano polypropylene fibers under 100nm is employed.
This enables products to absorb up to 50 times their weight in oil without water absorption—a 3-5 times improvement over traditional materials (10-15 times). Products are treated for anti-static compliance with ISO 9563:2006, fire resistance per NFPA 652, and use RoHS-certified recycled PP materials for environmental friendliness.
Bignanotech adheres to Vietnam’s Decree 08/2022/NĐ-CP on hazardous waste management and offers mobile Spill Kits (absorbing 10-15 times their weight, including gloves, bags, and scissors) for rapid 5-10 minute responses. Through a partnership with ASPiA JAPAN—a leading nano fiber company in Tokyo—Bignanotech launched the ECOSAS line in 2022, expanding its global reach.
