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.
