Potato waste and sweet potato waste utilization – some research trends

The aim of the present paper was to show in a summarized and systematized form, with the help of a search of relevant keywords in scientific databases and applying a descriptive approach, some current research trends concerning possibilities for potato waste and sweet potato waste utilization. The areas in which intense work is being done in the field of potato waste and sweet potato waste valorization are heterogeneous and diverse, such as bioethanol production, anaerobic digestion, adsorption of dyes and heavy metals, recovery of bioactive compounds, production of composite films, synthesis of nanoparticles, application as components in animal nutrition, attempts to include them as ingredients in food production. The goal of proper treatment and sustainable handling of these waste materials is to give them additional value and utility, to derive the greatest possible benefit from them, to minimize risks and negative consequences for the environment, and to protect the wellbeing of society as a whole.
