Shinnippou, a company which has been in business in Yaizu for around 40 years, has been running 808FACTORY since January 2014. According to the company, 'With food security and safety being a modern-day necessity, it is our mission to deliver fresh and tasty vegetables cultivated in a factory subject to careful quality control.'
Yaizu, Shizuoka Prefecture
Looking inside the facility, it can be seen that 12-level cultivation racks have been installed in the 2,000 m2 cultivation room to improve the cultivation efficiency per unit area. These provide space for at least 300,000 plants, and a daily harvest of 20,000 plants.
The right lighting
Katashi Kai describes: 'The greatest advantage of a plant factory with artificial light is that it can produce and supply steadily throughout the year, irrespective of climate and environmental variations. Also, by completely eliminating dust, insects and foreign substance contamination through advanced cultivation management and hygiene control, we can produce very safe vegetables of high quality without using pesticides at all.'
The company has now installed around 12,000 Philips LEDs. As a result, electricity costs are around 40% lower than when fluorescent lights were used, and the growth rate of the vegetables is 20 to 30% faster. The higher growth rate means higher yields in the same facility of a given area, which in turn means that the cost of producing a vegetable of the same quality and the same size can be reduced. Meanwhile, there was no change at all in the taste or nutritional value of the vegetables.'
