As an international systems and technology partner, JRS, J. Rettenmaier & Söhne GmbH + Co KG offers manufacturing capacity for market support, special projects and pilot projects. JRS carries out contract manufacturing in the fields of pharmaceuticals, foodstuffs, animal feed, plastics and other technical applications.

Newly developed products are manufactured in JRS facilities at several locations in any desired volume. JRS customers have access to already existing facilities and can offer new products faster. Demand fluctuations are buffered by JRS as a contract manufacturer that usually handles several manufacturing orders during the year on the respective system provided. Speed, reasonable prices and an environment that adapts to the constantly changing legal requirements are the decisive basic motivations of customers to make use of outsourcing. In the life sciences areas, the main motivations for working together with JRS are the high regulatory requirements and the high amount of documentation work as well as the high minimum hygienic requirements.

The focal points of the product range cover:


-active ingredient and auxiliary material grinding in jet mills in an FDA certified active ingredient grinding operation
-adaptation of pharmaceutical auxiliary materials through spray agglomerate, process granulation, mixing, size reduction, screening, dust removal, drying and pelletizing
-development of tablet press and coating formulations at the customer’s request

Foodstuffs and animal feed:

-mixing, granulation, coating, compacting and pelletising of thickener systems, sweeteners, minerals, plant fibres and feed components
-special manufacturing lines for halal/kosher products and different GMP requirements
-size reduction, screening, dust removal, drying and pelletizing
-special treatment of products for export to Japan


-recycling on shredding systems, e.g. parts, punching waste, V-belts, flat gaskets etc.
-grinding of polymers, elastomers, hot melt adhesives, and water-soluble polymers on custom grinding machines, optionally under cryogenic or moisture control
-conversion of plastic additives into dosable free-flowing shapes by means of press granulation

Technical application fields:

-adaptation of detergent raw materials and diverse other raw materials to market-compatible delivery forms by means of different granulation and coating methods
-production of mixes
-size reduction, screening, dust removal, drying and pelletizing

The system and technology partner offers individual customer solution approaches along the value creation chain, starting with innovation management, continuing with dosing and conveyor technology of the products, up to production and logistics management.
