this prevents the tyres from ever being retrieved and recycled. Creating a monofill
makes tyres available for future use.
Once there is an operational monofill then waste tyres should be banned from
regular landfills, as was done in Britain. This prevents valuable material from being
disposed of where it is inaccessible. This ban will also help to alleviate the burden on
the three landfills in Hong Kong. Due to the relatively small volume of waste tyres
generated yearly only a small parcel of land would be needed to create a monofill.
Levying a tax or disposal fee onto the cost of new tyres would provide revenue to
support recycling. The income from the tax could cover costs such as waste tyre
transportation, monofill management, rubberized asphalt and private industry that
recycle waste tyres into products. With an increase in the cost of new tyres, retreaded
tyres become even more economical.
Using rubberized asphalt in the construction of new roads and highways could
provide the largest outlet for waste tyres. For a small increase in price the roadway
lasts longer, creates less sound pollution and uses approximately one thousand waste
tyres per lane mile.
Retreaded tyres are as safe as new tyres and cost half as much. With the ability to
retread heavier tyres three or four times the life of a tyre can be doubled. This reduces
the number of tyres requiring disposal. By encouraging retreading Hong Kong can
reduce the waste tyre problem and save money. Some truck drivers are still unaware
of the savings associated with retreaded tyres, or they are misinformed that retreads
are not safe tyres.
The implementation of these steps would be a good start for Hong Kong to create
a sustainable tyre waste management system. Although these steps temporarily
alleviate the problem, more work still needs to be done. More research needs to be
