OLANGA software is a unique Swiss solution for food waste reduction in the catering industry. Together with renowned designers, IT experts and Swiss researchers we have developed the innovative mobile application OLANGA. An important future is the intuitive interface for a real time communication between customers and canteens. Using OLANGA, our customers can express their food preferences long time before they actually visit the canteen. This allows the canteens to avoid overproduction, to reduce personal costs and to increase customers satisfaction. Any leftover food can be bought at the end of the day through OLANGA at a discounted price. This is the perfect way using OLANGA to eliminate the amount of wasted food in the canteens and to reduce the environmental impact of your company.
