Present Status of Completely-controlled Plant Factories

Abstract

A plant factory is an all-year-round plant cultivation system under a controlled environment. It facilitates very efficient and stable production of vegetables that are chemical free, fresh, clean, and nutritious regardless of season or geographic location. The current drawback is the high depreciation expenses and high running cost. Recent incentive subsidies from METI and MAFF, however, are expected to achieve both cost reduction and production technology improvements.
