approximately 15,000 metric tons of scrap tyres are produced yearly. We identified

present and future tyre management techniques, through online research as well as

from private sector companies in Hong Kong. Currently, the only major form of tyre

recycling used in Hong Kong is the production of rubberized mats. A very feasible

option, which the government is already looking into, is the use of rubberized asphalt

in their roads. The only other method Hong Kong uses to manage waste tyres is

retreading, done on large government vehicles, on some trucks and minibuses, and on

all buses used by the Kowloon Motor Bus Company. We identified legislation used

around the world to regulate the number of waste tyres and to promote recycling.

Most countries impose a tax on the purchase of new tyres to subsidize the cost of

recycling. Britain has banned scrap tyres from landfills and instead has developed

monofills or dedicated landfills for excess scrap tyres, to promote the eventual

recycling of waste tyres.

By examining Hong Kong’s current system for dealing with waste tyres and

the models created by other countries, we concluded that Hong Kong should

implement five different management techniques to create a sustainable waste tyre

management system. First, inspections and maintenance should be more frequent to

prolong the lives of tyres. Second, Hong Kong should create monofills to allow for all

tyres generated to be recycled at a later time as well as banning tyres from landfills to

save landfill space. Third, a tax should be levied on new tyres to fund recycling and

reuse efforts. Fourth, the Environment, Transportation, and Works Bureau should use

rubberized asphalt in the construction of new roads. Fifth, the use of retreaded tyres

should be encouraged, especially by organizations with fleets of large vehicles.
