Chapter 4: Results and Analysis
In this section we will present the results of our data gathering in Hong Kong.
Having determined the scale of the problem we were able to single out methods of
recycling that were capable of dealing with the volume of tyres, while rejecting
measures too expensive to be used with the volume of tyres available. We then
analyzed the options applicable to Hong Kong by contrasting possible techniques of
waste tyre recycling with legislation both present and applicable in the future.
4.1 Scale of the Waste Tyre Problem in Hong Kong
Through an interview with Mr. Simon Lee (Appendix E) of the Hong Kong
Environmental Protection Department (EPD), we determined the scale of the problem
with waste tyres in Hong Kong. We found that while waste tyres are a very small
percentage of the total waste in Hong Kong, almost nothing is currently done to
prevent their accumulation in landfills. The EPD estimates that there are
approximately 18,000 tons of waste tyres dumped annually in the landfills, by a 2005
estimate. EPD estimates also put waste tyre accumulation at 50 tons per day.
Unfortunately, the only action taken to alleviate the problem with waste tyres is
legislation requiring all waste tyres to be split in half before burial in the landfill. The
tyres are buried with the rest of the trash, not in a monofill, a separate burial site for
waste tyres only, and therefore cannot be collected for recycling at a later date.
Mr. Lee also informed us of a resource that deals with the statistics of motor
vehicles. In this source, government records and surveys are detailed, and most
notable is a breakdown of the different kinds of motor vehicles. To our surprise, we
found cars and taxis make up the largest percentage of all motor vehicles (see Figure
