ProChem GmbH site Dieburg
Since March 2009 ProChem GmbH operates the synthesis plant(formerly James Robinson GmbH) in Dieburg located in southern Hesse (Darmstadt-Dieburg district). Covering an area of 23,000 square meters, a large number of reactors for synthesis and liquid mixtures, vacuum drying plants and process technologies for the processing of chemical substances are located in five production units. Due to the connection to centrally generated heating, cooling and inertisation media, all production areas in Dieburg have thermal processing technology. The hazardous materials warehouse and the solvent storage facility enable our highly trained employees to handle complex chemical substances. Through our own laboratory with attached pilot plant, we are able to accompany our customers from product development through implementation to the ton scale. In addition, the plant has a wastewater treatment plant, exhaust air combustion, extinguishing water system and corresponding peripherals for contract production. In close cooperation with the authorities and the existing certifications, we are able to serve customers with EFfCI and cGMP requirements in addition to serving classic specialty chemical manufacturers.

ProChem GmbH Rodgau plant
We have been operating a production facility for food additives at our Rodgau location since summer 2024. We have installed various production systems for mixing, powder refining, extraction, compaction and spray drying on site in order to be able to offer our customers in the food industry a wide range of contract processing options. Some of our production cells have air drying systems, so that we can also process highly hygroscopic solids without any problems. We use modern quality assurance measures and have filling systems with protective screening and metal detection. We are aiming for FSSC 22000 certification by 2025.
