Abstract

The objectives of this study were to explore how to manage waste tires in Chiang Mai area, and to propose guidelines on energetic utilization of waste tires. Data collection was conducted using a survey of waste tires collected in the study area, and from secondary data from various sources. It was found that waste tires mainly were available at auto - repair services, car service centers and driving schools. The amount of waste tires were about 900 wheels per day, or 27,000 wheels per month. Waste tires of about 1600 wheels were dumped in various places. Those that were found around Don Chan Ring Road accouted for about 22%, followed by Khuang Singh Road of 20.72%. It was reported that waste tires were either donated to the government offices, sold as used tires, and discarded. The waste tires contained up to 37,185 kJ/kg. They can be processed into fuel. There are three methods of the use of waste tires, (i) to convert into crumb rubber, (ii) to set a pyrolysis plant to senate pyrolysis oil, and (iii) to set up a power plant to senate electricity. From economic and investment analysis, it was found that the pyrolysis plant is the most suitable option. The payback period is not long. There are many product ranges. Setting up power plant requires high investment. Operation cost is a loss every year.
