Reducing food waste with novel biomaterials technologies

Food waste reduction offers multi-faceted wins for people and planet, improving food security, addressing climate change, saving money and reducing pressures on land, water, biodiversity and waste management systems. Numerous approaches are being taken to tackle the food waste problem. Some of them are technology-based with the goal of sustainably producing more food with less inputs and to minimize food waste from farm to fork. Particularly interesting is the case of precision agriculture, where nanotechnology and artificial intelligence (AI), combined with robotics, geolocalization, smart sensors, and big data analysis, could hold the key to unlocking global food security challenge.
