The transport of roses to the Netherlands, followed by days of export simulation and then flowering tests, were part of the GreenCHAINge project. 

Good vase life after sea transport

The GreenCHAINge consortium, made up of trading companies and research institutions, says it was satisfied with the results of the first sea transport of roses in 2014. 

The practical test involved transporting both large and small-flowered roses between the port cities of Mombasa and Antwerp. Conditions in the air-conditioned reefer containers (such as the required low temperature and relative humidity) were controlled remotely. After the 25-day transport, the roses were subjected to another eight days of simulated conditions of export to various European destinations (two days of cold storage, two days in transport containers, and four days of retail outlet conditions) and finally a test for keeping quality in the vase. 

The average vase life for these roses was ten days, which was not at all inferior to the roses transported via air-freight in which, unlike sea transport, the temperature is often difficult to control. 

Environmentally friendly

“The results were fantastic”, said Robbert van Willegen of GreenCHAINge, manager of this project. “The sea transport of roses imported from distant locations or exported to distant destinations is not only less expensive but also much more environmentally friendly. It generates 87% less CO2 emissions than transport as airfreight. We also transported all the varieties we loaded onto the ship onto an aircraft for the purpose of making a reliable comparison of keeping quality. Other kinds of practical tests will be conducted over the course of the year. In the upcoming months, other aspects involving the differences between transport modes will be investigated. Seasonal factors will also be examined.’” 

About GreenCHAINge

This project, which is being coordinated by the VGB, the branch organisation for the wholesale floriculture sector, is focusing on transport by ship and rail instead of by air or road. Also involved are plant breeding companies (Plantum), growers and wholesalers (FleuraMetz, Dutch Flower Group and Hilverda de Boer). 

Wageningen UR Food & Biobased Research (WUR), the Kenyan Flower Council (KFC), FlowerWatch, and logistics services provider, Maersk Line, is supporting the project. GreenCHAINge is being subsidised by the Dutch Ministry of Economic Affairs via the Topsector Tuinbouw programme, and by contributions from funds provided by traders and producers affiliated with Productschap Tuinbouw (PT).
