Key Takeaways
- Norway’s first fully automated vertical farming facility produces lettuce without human contact, enhancing hygiene and shelf life.
- The technology extends lettuce shelf life from 2-4 weeks to 12 weeks, significantly reducing food waste.
- Automation alleviates workforce challenges, making it suitable for future crop production, contributing to food security.
Revolutionizing Vegetable Production
Norway has launched its first fully automated vertical farming facility, located near Oslo. Operated by Himmelgrønt AS, a collaboration between Coop Norge and Avisomo, this facility enables year-round production of vegetables without pesticides or imports. Since its opening last fall, the first products have begun reaching store shelves.
The vertical farming method used here allows crops to grow in controlled stacked layers, with robots managing every task from sowing to packaging. SINTEF researcher Ottar Bakås explains that because the crops are grown and processed without human touch, the risk of disease contamination is significantly minimized. Lettuce can be harvested within just over two weeks, with nutrients delivered through flowing water directly to the roots, while the plants grow above.
One of the most impactful aspects of this technology is the extension of shelf life. By increasing the longevity of lettuce and herbs from a mere 2-4 weeks to an impressive 12 weeks, the facility helps reduce food waste in supermarkets. Aleksander Lillienskiold, a former SINTEF researcher, indicates that a longer shelf life enables stores to offer a wider variety of vegetables, potentially encouraging higher consumer purchasing and promoting public health.
This automated approach addresses labor shortages in Norway, particularly in the agricultural sector, by utilizing robots for harvesting, which reduces the need for a large workforce. The technology not only minimizes heavy labor tasks but also allows for a more varied range of roles within the workforce.
Researchers at SINTEF are actively exploring how the automation methods used here can be applied to other agricultural production tasks, while also determining suitable levels of automation based on investment needs. This adaptability is crucial for scaling up production volumes.
Furthermore, a report from the Norwegian Defence Research Establishment identifies food supply as a vulnerability during crises. Thus, local and automated vegetable production strengthens national preparedness and overall food security.
In tandem with this project, SINTEF has initiated another focused on meat automation, AutoMeat. This initiative assesses whether knowledge from the fishing industry’s quicker adoption of automation can be leveraged in vegetable production.
This pioneering facility not only underscores advancements in food technology but also elevates the standards of hygiene, efficiency, and sustainability within Norway’s agricultural landscape.
