“PolyOne enables our customers to maximize their productivity, and helps to prevent product recalls,” says Christoph Naef, head of business unit nutrition at Bühler Group.

PolyOne meets the highest food and feed safety standards thanks to its hygienic design. It is a modular system, so it can be adapted to customers’ specific needs, such as higher capacities.
