and implementers from the start of R&D. The authors propose an R&D
implementation and evaluation team (Fig. 28.2). The role of each member is as
follows: researchers conduct laboratory-scale cold and hot tests for collecting
basic information on waste inventory and treatment technology, implementers
carry out engineering-scale cold and hot tests for commercializing the technology, and system engineers carry out the system design and cost evaluation of
