The story
RETHMANN first became active in the field of recycling animal by-products when it took over the firm "Gebr. Schaap" in Marl, Germany in 1977. SARIA Bio-Industries AG & Co. KG was then founded in 1998 as an independent division of the RETHMANN Group. The new company united all of the Group's activities within the product and service segments that had previously been run by a number of companies including RETHMANN TBA GmbH & Co. KG.
Processing plants were already being operated at the time of the company's foundation in:
Germany (7 plants)
Austria (1 plant)
Czech Republic (1 plant)
France (10 plants, previously Soporga and SFM)
Spain (1 plant)
Poland (1 plant)

Since 1998, the company has been steadily growing in size by expanding into new areas, extending existing processing plants, and by taking over existing companies operating in the same sector of business. The company now operates approximately 200 sites which are located in 26 countries worldwide. A milestone in the company's history was, for example, when it put Germany's first ever plant into operation in 2001 to produce biodiesel from animal fat. This plant is located in Malchin, Germany. Further plants have followed, with vegetable oils now also being used to produce biofuels.
