Mitsubishi Sells Vegetable Plant System to Railway Firm
Mitsubishi Chemical Corp sold a vegetable plant system that uses only artificial light of LED and fluorescent lamps to facilitate photosynthesis of vegetables to Hanshin Electric Railway Co Ltd.
With the system, Hanshin Electric Railway will grow baby leaf vegetables and sell them to department stores, hotels and convenience stores run by its group companies.
The vegetable plant system is a hydroponic system that does not require soil. And the temperature inside the plant is kept constant with an air conditioning system. It enables to grow fresh, safe vegetables without agricultural chemicals, Mitsubishi Chemical said.
The area for cultivation is 139.06m2. The time between sowing and harvesting is 21 days. The company will start to ship the system in April 2014.
In February 2012, Hanshin Electric Railway installed "Hanshin Test Vegetable Plant" underneath the elevated railway tracks between the Daimotsu and Kuise stations. The latest system will be installed in a new vegetable plant underneath the elevated railway tracks near Amagasaki Center Pool-mae Station.
In locations such as places underneath railway tracks, where the amount of solar irradiation is low, vegetable plant systems that use only artificial light are preferable, Mitsubishi Chemical said.
