RoseDowns and Serptec combined design technology and manufacturing expertise are a major contributor in the processing of animal and other waste products.

RoseDowns have an unrivaled reputation worldwide for the manufacture of screw presses and the supply of high-quality spare parts to the rendering market.

With the acquisition in 2020 of Serptec, based in Verden, Germany the Desmet Ballestra Group has strengthened its position in the market and added to more than 30 years of expertise in animal bi-product processing.


We believe that RoseDowns have much more to offer to customers than merely manufacturing of presses and press components.
