Plant Factory as a Resource-Efficient Closed Plant Production System Chapter uri icon

  • 2016 Elsevier Inc. All rights reserved. To improve the resource use efficiency of a "plant factory with artificial lighting" (PFAL), it is important to understand the characteristics of the principal components of the PFAL. The primary input resources for the PFAL are light, water, CO2, and electricity and inorganic nutrients (fertilizer). This chapter describes and defines the resource use efficiency (RUE) for each component and explains the concept of a closed plant production system (CPPS) in order to improve RUE. The characteristics of the PFAL are compared with those of a greenhouse, mainly from the viewpoint of RUE. It is shown that the use efficiencies of water, CO2 and light energy are considerably higher in the PFAL than in a greenhouse. On the other hand, there is much room for improvement in the light and electric energy use efficiencies of the PFAL. Challenging issues for the PFAL and RUE are also discussed.
