Origin Core Solution - Our Philosophy
OCS Co., Ltd. proposes a new paradigm of resource circulation based on the philosophy embedded in the name Origin Core Solution.
Origin - The Origin of New Value
We recognize discarded materials not as mere waste, but as the origin of new value and a latent resource. This embodies our ambition to create a sustainable future by redesigning resource circulation systems from their very foundation.
Core - Core Technology and Expertise
We lead the industry based on core resource recycling technology and unparalleled expertise. We provide innovative solutions that penetrate the essence, or core, of the resource circulation process.
Solution - Effective Solutions
Beyond simply recycling resources, we present clear and effective solutions to resource scarcity and environmental pollution. We provide optimized solutions for sustainable resource management that meet the demands of customers and society.
Revolutionary Transformation of Rice Husks - Our Core Technology
OCS Co., Ltd. transforms discarded rice husks into high-value industrial materials through its patented technology.
Silica
High-purity silica extracted through eco-friendly processes is used as a core material in the tire industry. It improves durability and grip while also enhancing fuel efficiency.
Microcellulose
Natural cellulose microparticles are utilized as stabilizers and fillers in the toothpaste and pharmaceutical industries. Its excellent biodegradability minimizes environmental burden.
Lignin
Used as a natural additive in the food industry, lignin, with its antioxidant properties, holds potential for application in various industrial fields.
Our innovative technology not only reduces waste but also aims to complete the circular economy by sustainably supplying high-quality materials required by industries.
Patented Technology - Our Competitive Edge
OCS Co., Ltd. holds core patented technologies to secure a unique position in the field of resource circulation.

Patent 1: Rice Husk Separation and Purification Technology
This eco-friendly process efficiently separates silica, micro-cellulose, and lignin from rice husks, significantly reducing energy consumption and chemical use compared to existing methods.

Patent 2: High-Purity Bio-Silica Extraction Technology
This technology enables the eco-friendly extraction of over 99% pure silica from rice husks, allowing for the production of high-quality bio-silica that can replace synthetic silica.
Our R&D team, composed of experts in each field, continuously improves technological capabilities through ongoing research and is dedicated to developing further patents.
