Plant factories with artificial lighting (PFALs) toward sustainable plant production
This paper briefly describes the past and current status of plant factories with artificial lighting (PFALs) and the perspectives on environmental and economic sustainability, based on the authors' previous work and views. First, the resource consumption and production cost kg‑1 of fresh produce in the PFAL are reviewed. Then, the relative operation and initial costs for controlling environmental factors are roughly estimated. Next, preferable plant traits for commercial production using PFALs are discussed. Furthermore, yearly sales and electricity cost as well as production costs kg‑1 of produce are estimated for PFAL-grown leaf lettuce, rice, and strawberry, assuming representative parameter values in Japan as of 2018. Based on the above, recent technologies to be implemented for the next-generation PFALs are described. Among those technologies, the potential importance of plant phenotyping is discussed in terms of resource efficient plant production and breeding of plants suited to PFALs.
