Team and roots

Energy-IO started with measuring cases in 2009. The driving force behind the operation is Ton van Ewijk, with over 25 years of experience as a process technologist and plant manager at companies such as Tetra Pak, Akzo Nobel, Nedmag, Remag Delfzijl, DSM, Foxfire and FrieslandCampina. Says it like he sees it, is genuinely upset by waste and likes to challenge in order to transform line managers into energy administrators.
