Obsoleszenz - auch ein Thema bei Lebensmitteln : Ergebnisse einer Expertenbefragung
(2018) Gebhardt, Beate; Ding, Jana-Lisa; Feisthauer, Philipp
Obsolescence is a topic that also concerns food products. Popular science has speculated that to a more or less significant extent, actors involved in food value chains were responsible for preliminary spoilage of food products. This speculation is true. Research and food experts in the field confirmed this during an expert survey conducted in 2015. This paper presents this survey. Experts confirm the main issue of this analysis which sheds light on the relevance of the following idea: Is obsolescence a topic regarding food products or does it only concern (technical) consumer goods? Only the latter is currently under debate. In total, 19 researchers and practicians from food value chains were surveyed and the majority shares this view. However, not all of them agree. The topic polarises researchers in particular. Eventually, issues such as the waste of ressources and social disparity due to food waste are not very disputed, irrespective of the reasons they emerged, but rather those responsible for the issue as well as the term that is to be used when food products spoil or are disposed preliminarily: obsolescence, food waste, avoidance, or other. The ensuing question focuses on this by addressing the advantages or added value if food waste was introduced into the debate on obsolescence or, on the contrary, if food waste was perceived in light of the debate on obsolescence. In this regard, we must emphasise the following key topics: 1) Avoiding arbitrary authority of definition: Shifting a term and generating authority of definition regarding (planned) obsolescence in merely specific areas is arbitrary. There are no objective reasons to apply obsolescence solely to consumer goods or technical devices. Irrespective of the type of industry, product, or the product’s shelf life, the reasons and circumstances for which products spoil preliminarily are similar in many aspects. Problems and reasons of unnecessary use of resources arise along the value chain due to processes and practices on all markets of modern and innovative societies. 2) Corrective of consumer responsibility: Addressing manufacturers and retailers represents a corrective when handing over responsibility for food waste. Especially in the food sector, to much responsibility is falling on consumers. In general, the aims of mitigating waste of resources are disputed. It should not pursue the way of least resistance and address primarily consumers. The corrective of consumer responsibility enables a corrective for solution-oriented approaches with greater diversity along the whole food value chain. 3) Problem-centred revision of definitions: In light of food waste, the use of natural materials and the role of agriculture are often neglected, described as inevitable, or excluded by definition or regulation (e.g. harvesting losses). However, obsolescence and its clear distinction between natural and artificial (planned) obsolescence does not fundamentally alter the view on natural resources of food and their use. Moreover, the necessity to critically revise regulation (e.g. the German Waste Management and Product Recycling Act) becomes clear. 4) Learning from and with each other: Changes in perspective and exchange among experts in debates on obsolescence and food waste are the bedrock to learn about tools, solutions, as well as experiences and mistakes made by others (e.g. proposal for a shelf life indication for technical devices without referring to experience with best-before indications of food products). Topics for further research include interdependencies and conflicts of targets which concern innovation for sustainability, shortage of product life cycles as well as the establishment of standards as means for more transparency to check their contribution to obsolescence and identify approaches for more appreciation in the overall concept considering all market participants.
