With Tradition and Clear Values for a Future Worth Living.

We believe in a better future and want to do our part to make it happen. That’s why we use our innovative JRS plant fiber technology to improve food products, pharmaceuticals, and industrial processes. In this way, we create solutions for today’s needs and tomorrow’s challenges — for people, the environment, and a future worth living.

That Makes Us Uniquely Different.

Fibers from Nature.
Solutions from JRS.

As global active manufacturer we produce our high quality functional fiber products from renewable raw materials such as cereal and fruit fibers, marine plants, wood and the cellulose derived from it. 
With every fiber, we work to use resources responsibly.

Plant fibers offer a wide range of functional properties. Our mission is to understand these properties and harness them for industrial applications. With our innovative JRS plant fiber technology, we unlock the potential of plant-based raw materials for a wide range of applications. We translate the diverse functions of these raw materials into holistic, customized solutions for customers around the world and across nearly every industrial sector.

The Right Solution for Every Challenge

Uniquely Diverse - JRS Plant Fiber Technology

In this way, a wide variety of plant-based raw materials are transformed into functional products made from cellulose, grain and fruit fibers, algae, or wood fibers. The focus of our work is on developing functional solutions based on plant-based raw materials. Because only by thinking and acting with a long-term perspective today can we be successful together tomorrow.

Unlike the textile fiber our fiber products consist of very short fibers which usually appear as to the bare eye. Generally the difference and the wide range of functions they perform are only visible under a microscope. Diversity is the common theme that drives our company and it is expressed most clearly in the many different fiber products we offer.

Our unique technological know-how, many years of production and application experience and global presence provide our customers with confidence and deliver collaborative solutions which are precisely tailored to the customer’s needs. So you gain a competitive advantage through our leading position in process technology.
