Since 2002, we have been providing comprehensive advice to biogas plant operators and offering our customers specific solutions.
Our product portfolio has grown along with the tasks. Today, our portfolio includes not only liquid iron salts and activated carbons for desulphurisation – we also offer other important products and services for the efficient operation of a biogas plant from a single source.
