The GreenSource system is an example of what open innovation can lead to. Royal TenCate, Pentair and Drain Products joint their efforts to find a sustainable solution for the drinkwater problem of the North-West province in South Africa. In this way, knowledge of synthetic turf systems, water handling & storage and water filtration was combined in a pragmatic way. The joined forces of these multinationals in East Netherlands are combined with the Saxion University, Landscape Solutions, Mmapula Community Development, Royal Turf SA, local public bodies in South Africa and the Dutch Ministry of Foreign affairs to install the first 20 GreenSource systems.
