The Foundation for Applied Research in Water Management (STOWA) is the expertise institute of regional water managers in the Netherlands. STOWA develops, gathers and disseminates the knowledge needed to properly carry out the challenges and tasks faced by Water Authorities. Examples are climate change and energy efficiency. But also the recovery and recycling of raw materials from the water chain, such as biopolymer from sludge from Nereda® purification plants. With this in mind, STOWA has signed the Green Deal Raw Materials. You can find more information about us and our work at
