Wastewater from olive oil production used to be dumped in ponds and left to create a big stink. But now researchers from the Institute for Agricultural Research and Training and the Institute of Fat have found a new use for it: fertilizer.
Despite its versatility and low production cost, palm oil has been proven to be harmful to both human health and the environment. A new creation from Sevilla could act as its replacement: Nutrisun, a combined sunflower seed oil. It´s patented by the Institute of Fat, part of the Spanish National Research Council.
