We, the JRS, J. RETTENMAIER & SÖHNE group of companies, have dedicated ourselves to the research, development and processing of high-quality, functional organic fibers made from renewable, vegetable raw materials.

In doing so, we make the many functions of these valuable natural materials available to industry.

These include functional products made from cellulose, cereal and fruit fibers, or wood fibers, processed as needed into ultrafine fibers, compacts, granules, blends, or special dosage forms.

Behind this is the innovative 'EPT', Enhanced JRS Process Technology' with its unique, innovative process engineering modular system.
