Sustainability is a central issue in food business and food retailing since approximately 3 years (See Teitscheid 2011). Various influential factors are significant for this development. On the one hand consumers choices are changing (See GFK et al. 2009). They are looking for natural, good and healthy food; they have a longing for home and an intact world (See iSuN 2010). The image of a highly efficient, but often ruthless industrial food production in regards to mankind and nature is not appropriate here. On the other hand, raw materials are scarce and, thus, very valuable. Bad harvests, mostly interpreted as a result of climate change, worldwide increasing consumption and the production of food in favor of energy production instead of nutritional aims, lead to a re-evaluation of agricultural resources and their producers. Within this context, food industry is searching for new forms of cooperation and partnership along the value chain in order to secure their resource basis. In the light of their significant environmental impact, an increasing number of companies also start to work on the environmental assessment and optimization of their products and value chains. Therefore they need employees with valid knowledge and competencies in sustainability and resources management. Based on this demand, the master's program "Sustainable Services and Nutrition Management" started in 2009 in the University of Applied Sciences in Münster (Germany)1. This text reports about how the topic of resource efficiency in food/nutrition industry has been integrated within the study program, which projects have been worked on and what experience could be gained from them.

In the last decade, in many European Countries more and more measures have been initiated aiming at the prevention of food losses and wastes along the entire value chain. In order to evaluate or monitor such important measures it is crucial to obtain quantitative information on generated food waste amounts, subsequently enabling the quantitative evaluation of the measure’s outcomes and efficiency. Currently there is a paucity of quantitative information, particularly on food losses that are directly generated during harvesting processes. Up to date, no method is available or standardised aiming at the in-situ or on-site quantification of food losses during harvest. Using the example of the potato harvest, this study presents a practical approach for determining potato losses. To test the applicability of the developed method, on-site measurements were conducted directly on the field at five different locations in Austria and Germany. Our method enables the quantification of food losses based on defined areas along the harvested potato rows, where the analyser manually collects potatoes during their harvest. Hereby, two types of potato losses needs to be considered: non-harvested, under-sized potatoes that remain under the earth and the harvested ones, which are rejected on-site because of quality requirements regarding their size, shape, and state of health. Our study shows that between 1 and 9% of field losses (based on yield potential) can be generated during the potato harvest. In future, this method may be the basis for standardised protocols in order to be able to derive cultivar-specific benchmarks and, consequently, to develop measures for preventing food losses. In general, more case studies and evidence-based ground-up measurements on other cultivars and for other regions are needed focusing on the on-site quantification of post-harvest losses.
Food-processing companies are controlled by societal influences and economic interests, but their efforts with regard to reducing food loss and waste are very different. This qualitative study aims to identify basic recommendations of good practice for the food-processing industry in order to prevent and handle food loss and waste. For this purpose, a comprehensive literature review was conducted in the field of food waste prevention and data was collected from thirteen German companies. The findings summarize the recommendations of good practice, which cover the entire supply chain from supplier to consumer and beyond. The analysis showed that the participating companies are already partially aware of operational measures, even if they are applied or mentioned without a systematic approach. Furthermore, the analysis revealed that most activities relate to internal matters, like processing, employees and utilization. However, the responsibility of foodprocessing companies does not end with internal processes to reduce food waste. The results show that some companies are already aware of their responsibility to be involved along the entire supply chain. Finally, the results show that the needs of consumers and suppliers must also be considered in order to reduce food waste, in addition to direct reduction measures. This paper highlights nine important stages and 53 basic recommendations for companies to address food loss and waste in order to improve their practices.
