Dear Mr. Thompson,
Thank you for your inquiry into the current status of ozone layer protection efforts in Taiwan.
I would like to briefly describe some of the related activities undertaken by our organization,
the Industrial Technology Research Institute (ITRI).
Organizational background ITRI is a non-proft research and
development institute funded primarily by government and industry. Governmental funding is
used to develop and perform national mid- to long-term application/research programs, as
well as to assist medium and small-sized enterprises. On the other hand, private (industrial)
funding is invested in jointly cooperative projects and technical assistance.
Governmental relations In light of the importance of protecting
the ozone layer and of the need to alleviate the possible economic impacts of CFC phaseout,
the government of the Republic of China has assigned ITRI to conduct a long term project to
research application technologies that have been implemented to protect the ozone layer
Previous efforts in the area of concern During the past five
years, ITRI has published a monthly CFC Newsletter, five volumes of a "Handbook on CFC
Utilization," and more than twenty special investigation reports, so as to provide local
industries with updated information on alternative technologies. More than twenty seminars
on technology development have also been organized by ITRI to assist domestic industries
alleviate CFC problems.
ITRI also continuously visits hundreds of industries to collect information on the current status
of CFCs and the major obstacles we will face in the future. ITRI also provides promotion and
other services related to the reduction and recovery of CFCs and the use of new alternative
technologies. Technological developments Major achievements
attained so far include the following:
A. Development of a CFC refrigerant recovery machine and successful transfer to four local
B. Completion of performance evaluation of automobile air-condition systems and refrigerators
with HCFC blends
C. Completion of a feasibility study and computer simulation on replacement of R-12 by
D. Development of non-CFC mobile refrigerant technology and its successful transfer to ABC
E. Completion of two sessions of non-CFC refrigerant substitution technology, with 60
2. Foam blowing
A. Completion of a study aimed at replacing CFC-12 with HCFC-22 on PE/PS foaming
B. Completion of a study of PU integral skin aimed at replacing CFC-11 with HCFC-123 or
C. Assistance provided to DEF Corporation in their evaluation of the introduction of
HCFC-141b on rigid PU refrigerator foam
A. Completion of a study of IPC standard tests of electronic test boards
B. Completion of an evaluation of aqueous, semi-aqueous, and no-cleaning processes
C. Establishment of a DEMO Center for electronic cleaning to assist local industry in the
evaluation of cleaning effectiveness
D. Successful introduction of a non-cleaning process at five local electronics plants
E. Successful assistance provided during the introduction of an IPA cleaning process to an
optical lense plant
4. Chemical analysis and testing for CFCs
A. Development of analytical methods for analyzing CFC residues found in foam products
B. Offering of certification services for the export of foam products
C. Development of an analytical technology for refrigerant purity
ITRI's efforts have resulted in a significant ODS phaseout in Taiwan, with a 30% reduction, in
1992, over that of the base-line consumption level. Enclosed please find two tables summarizing
ITRI's major achievements in CFC phaseout for the 1993 Fiscal Year (July 1992 to June 1992).
Acknowledgements from the EPA, GHI Corporation, the Tools and Machinery Association, as
well as news clippings on ITRI's related work are also appended.
In addition to assisting the government in related policies and regulations (e.g., CFC phaseout
strategy, CFC control strategy, and the recycling and reuse of mobile refrigerant CFC-12),
ITRI also took an active role in organizing Taiwan's Association of Ozone Layer Protection.
In January 1993, the association was established to continue work on ozone layer protection
and to integrate resources from industrial associations, research institutes, academia and
Related international activities ITRI has also sent delegations to
attend the Montreal Protocol Meetings, where our delegations exchanged information and
established collaborative relations with representatives from many countries. The R.O.C.'s
willingness to participate in global ozone protection efforts, as well as to comply with the
Protocol was expressed during those meetings.
I hope that this above information clarifies some of our involvements in the area of ozone
layer protection. I would be happy to answer any questions you might have.
