Resource-efficient Production of Convenience Salads

Project duration: April 2019 to December 2020

Wiegert Convenience GmbH, a Viennese family business with a decades-long tradition of growing, processing and trading vegetables and fruit, is improving its range of ready-to-eat sliced and packaged salads, known as convenience salads.

These products currently only have a shelf life of 4 to 5 days, meaning that a relatively large proportion of them do not reach consumers in time to be consumed and have to be discarded as waste. Together with FH Campus Wien and the Food Research Institute, modifications to the production and packaging process are being developed to ensure an extended shelf life of 6 to 7 days while reducing the use of other resources in production, such as water. This gives the producer-consumer supply chain more time to get the products to the table so that fewer products spoil and become waste. The most precious resources besides land, food and water, are conserved and utilised more sensibly through an improved production process.
