Turning waste water into three valuable products: nutrient rich irrigation water, high quality compost and fish. That’s the plan of Jelmer van Veen (the Netherlands) and Priska Prasetya (Indonesia), which was worth a first prize in the. International Climate Adaptation Business Challenge today. The finals took place during the international conference Deltas in Times of Climate Change II in Rotterdam.
Their idea is to use domestic household waste water in Vietnam. First they separate the solid excrements and turn them into fertilizers. After that, the remaining fluids are filtered in a constructed wetland filled with gravel and sand. At last they use fish to eat the microplankton that grows on remaining nutrients. The clean water can be used as irrigation water for coffee plantations and the fish can be sold on local markets.
Jelmer and Priska receive € 25.000,- for implementing their business plan. ‘With the prize money we’ll go to Vietnam in December and, together with some partners, we’ll look for locations to start a pilot project, ’ says Priska.
