Development of knowledge to react to possible banning of single-use petroleum-based plastics that impact post-harvest management of stone and pome fruit quality

With increasing public awareness of the negative impact of plastic on the environment, retailers have started rejecting the use of single-use packaging. It is suggested that the fruit industry assists in developing intellectual capital relating to environmentally friendly packaging solutions, for which a knowledge gap exists.

The objective of this study is therefore to start equipping post-harvest fruit scientists with knowledge to address these needs, so that research can commence that aims at replacing, reducing and/or removing single-use plastics.

A literature review was conducted, referencing existing information with regards to single-use plastics, its alternatives and potential challenges. This review includes results from a comprehensive survey circulated to representatives of the fruit industry.

The functionality of plastic packaging is very much seen as an important factor in the fruit industry, as it relates to fruit quality management, which needs to be taken into consideration when alternatives are being looked at. There is potential in fruit coatings, as well as biodegradable packaging, however this needs to be combined with the re-use of plastic, i.e. returnable packaging.

A co-operative effort will be required to successfully perform industry specific research and develop technologies for replacement of disposable plastics within commercial settings, and test market acceptability by monitoring and redesign.

There is potential in fruit coatings and biodegradable packaging as alternatives to single-use plastics, however, this needs to be combined with replacing plastics typically used in fruit boxes for export with more environmentally friendly options. Fruit quality management is key to prevent food waste where alternatives are being considered.
