To satisfy the needs of the growing number of the world population, it is absolutely necessary to make the food supply chain more efficient and, at the same time, preserve the natural resources and manage the ecosystems adequately. Despite all adopted measures so far, the vegetable industry produces enormous amounts of waste over the year. In diploma thesis, we focused mainly on vegetable waste as a result of crop production, which consists of marketable as well as unmarketable crop parts. Differences in the quantity of waste produced are due to vegetable cultivars, harvest, and part of the season. For instance, most vegetable waste is produced in the middle of the season, where yield is at its peak. On average, 0.35 kg of waste is generated per plant. There are several reasons for such high waste: pests, diseases, high cosmetic standards, and market specifications are just to name a few. Therefore, it is highly unlikely that one quick fix would solve all the problems. A solution that works for a certain vegetable cultivar, production system, or harvest method, might not work for others. In my diploma thesis, we answered questions on the quantity of vegetable waste produce in vegetable production, how can the losses be reduced, and how vegetable waste, which is created in primary production, is handled with.
