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
