The mission of Dr. Morawicki's research is to develop the use of processing techniques to improve the long term sustainability of the food supply chain. As natural resources decline, the concept of sustainability will affect all areas of human activity, especially food production. Currently, food production operates as a linear open system that takes energy and materials from non-renewable resources along with water to produce food. Once these resources become less available, the capability to produce enough food for a growing population will be compromised. 

Research Goals

  1. Use of byproducts from food processing
  2. Production of compounds from waste materials via fermentation of chemical reactions
  3. Promote energy and water efficiency in food processing
