waste issues, because tyre waste is a relatively small problem in comparison to air
pollution and other municipal wastes.
Any recycling technology that contributes to pollution should be considered as
a less favorable option even if within regulations. Tyre derived fuel is an unfavorable
option based on both legislative and sociological factors. The pollution created in
making and using tyre derived fuel would not be acceptable in Hong Kong. Also, the
limited space in Hong Kong makes it difficult to build a factory.
Hong Kong is listed as having the world’s highest economic freedom rating
(Gwartney, 2006) by several comparisons. The government has very little impact on
business, because legislation or other means of government intervention is generally
frowned upon. Any recycling method that relies on government legislation, subsidies,
or any form of intervention would be unfavorable for the investors in Hong Kong,
who prefer free market incentives (John So, personal communication, February 5,
See Appendix H).
Due to the complicated structure and composition of tyres, recycling is very
troublesome. Despite this, there are many methods that have been proven in several
countries to be profitable. Based on existing laws and regulations, some of these
options, such as tyre derived fuel were found not to be feasible in Hong Kong.
Sociopolitical factors further reduced the options, although there are still numerous
recycling methods available that need to be analyzed. The objectives and the methods
we implemented to determine the most effective solution for Hong Kong will be
outlined in the subsequent chapter.
