Circular Food Processes

Waste management towards a circular food system

Generation of food losses (during food production and processing) and food waste (during transport, retailing and consumption) occur at every step of the food system. We need to develop new technologies that valorize the different streams and by-products generated during agricultural production and food processing into novel food and non-food products. In this context, the design and implementation of integrated biorefinery (chemical and biotechnological) processes is required. On the other hand, minimizing food waste at the distribution and consumption stages requires the integration of improved logistics and digitalization approaches. KTH FOOD researchers are designing new processes to upgrade by-products from agricultural production and also designing new active packaging material that fights food losses and waste, respectively. Also, industrial symbiosis can be used to use resources in multifunctional ways. For example, CO2 in ventilation air in buildings can be redirected to cultivation of edible plants.
