A consortium led by Fujitsu Home & Office Services Ltd will start a test of large-scale cultivation of low-potassium vegetables in a vegetable plant that was once a clean room for semiconductor production in Aizuwakamatsu City, Fukushima Prefecture, Japan.

There is a strong demand for low-potassium vegetables for those who cannot eat normal fresh vegetables because of the restriction of potassium intake such as dialysis patients and chronic kidney disease patients.

The area of the vegetable plant is 2,000m2. And it is the largest plant for low-potassium vegetables in Japan. Fujitsu Home & Office Services will start test production in October 2013 and volume production with a production rate of 3,500 units per day in January 2014.

The member of the consortium includes the Fujitsu Group, Aizufujikako Co Ltd and Fukushima Medical University. The project will be subsidized by Japan's Reconstruction Agency and Ministry of Economy, Trade and Industry.

Aizufujikako will provide knowhow for reducing the amount of potassium. Fukushima Medical University will conduct clinical tests.

As for the Fujitsu Group, Fujitsu Home & Office Services manages the project, improves production technologies and develops sales channels. Fujitsu Semiconductor Ltd calculates optimal production conditions in the clean room and provides knowhow for controlling bacteria in the aim of realizing an optimal cultivation environment for low-potassium vegetables by meticulously controlling the components of air and liquid fertilizer.

Fujitsu Facilities Engineering Ltd provides and improves the infrastructure and lowers power consumption. Also, it controls the entire business operation by using Fujitsu's "Akisai" cloud network to continually analyze cultivation data and keep productivity.
