Sustainabilityis our mission, and it drivesevery action at Blue Ocean Biotech. Taking sustainability to an all-new level we are poised to transform the precipitated silica market with our latest innovation - Green Silica.
Made from Rice Husk Ash (RHA), Green Silica demonstrates our commitment to sustainability with the transformation of waste into a valuable resource.
Green, eco-friendly and renewable Green Silica is ideal for an array of industries - tire and rubber manufacturing, food processing, pharmaceuticals, footwear, oral care, agrochemicals, and detergent manufacturing, among others.
Blue Ocean Biotech has the distinction of setting up India's first 100% green precipitated silica plant for harnessing the potential of Rice Husk Ash. The plant is powered exclusively by green energy and uses green processes end-to-end.
Presently boasting a capacity of 10,000 metric tons per annum (MTA), we are on track to soon expand plant capacity to 20,000 MTA, strategically aligning ourselves with the projected demand in the market. We have already made significant in roads into the industrial rubber manufacturing sector.
