It is an environmentally friendly activated carbon material that strongly adsorbs oil and does not sink in water for a long time.
"Sumirei" is an environmentally friendly recycled carbon material (floating activated carbon) made solely from carbonized coffee bean extraction residues. It has unique properties that allow it to strongly adsorb oil (hydrophobic liquids), repel water, and float on water. It can also adsorb oils mixed with surfactants, which cannot be adsorbed by conventional adsorbents at all. For more details, please contact us or download the catalog.

Company information
To reliably address oil leaks in all locations, such as road surfaces and water surfaces, we are pursuing performance that is not found in conventional oil absorbents, oil fences, and oil mats. Our products include "AC Light," the number one brand of oil absorbents for road surfaces, and the "Sumirei" oil fence and oil mat, which enable precise prevention of thin oil films spreading on inland water surfaces. Additionally, we develop and sell unique materials that are useful for "preventing the spread of turbidity and debris in rivers and waterways," "monitoring pipeline leaks," "anti-fogging for convex mirrors," and "first-time asphalt surface repairs."
