Technology options for treatment, storage, transportation, and disposal have
been proposed by domestic and international organizations. These options should
be integrated and managed in a database of technology options. R&D results should
also be added in the database as soon as possible. To manage the technology
options, a database should be prepared and used to share information among the
related organizations. The authors proposed a set of items to be managed in the
database of treatment technology options (Table 28.2).
When an appropriate technology is being selected from several options, it is
important to evaluate each technology option and compare them. At the end, it is
also important to evaluate the combination of technologies from treatment to
disposal to make the final selection of an appropriate set of these technologies
and to establish a total system for specific wastes. The authors propose a set of
indexes for evaluation of the combination of waste management technologies
(Table 28.3). Evaluation of the total system should include the long-term safety
of disposal because this is the most important issue and goal of waste management.
28.4 Formation of an R&D Implementation
and Evaluation Team
The development of a waste inventory database and waste treatment technology
and the evaluation of the feasibility of each technology and the total system of
waste management requires a team composed of system engineers, researchers,
