LCQ17: Handling of waste vehicle tyres
Question:
According to the paper submitted by the Environment and Ecology Bureau to the Panel on Environmental Affairs of this Council in November 2023 (the paper), nearly 30 000 tonnes of waste vehicle tyres were generated in Hong Kong in 2021, of which 70 per cent were generally first cut and disposed of at landfills, and only some 20 per cent were retreaded and reused or recycled. It has been learnt that although waste vehicle tyres disposed of at landfills will be cut first, it still takes a long time for them to decompose, which also leads to the problem of landfills being exhausted. In this connection, will the Government inform this Council:
(1) of the total weight of waste vehicle tyres generated in Hong Kong in each of the past three years, with a breakdown by the following methods for their disposal: (i) recovered and recycled locally, (ii) recovered and exported after treatment, and (iii) disposed of at landfills;
(2) of the weight of landfilled waste vehicle tyres that were handled by the Government in the past three years, and its percentage in the weight of all waste vehicle tyres disposed of at landfills; the reasons for not recovering and recycling such waste vehicle tyres;
(3) Whether the Government has compiled statistics on the maximum handling capacity, actual handling capacity and remaining handling capacity of waste vehicle tyre recyclers in the market at present; if so, of the details; if not, whether it will compile such statistics;
(4) Given that it has been learnt that in order to promote the local recycling industry, the Government had allocated 20 sites for lease to the industry by January 2024, of the details of such sites, including their location and size, the recycling projects involved, and the number of such sites used for handling waste vehicle tyres; and
(5) Given that the paper proposes that landfills no longer accept and handle the disposal of waste vehicle tyres, when the proposal is expected to be formally implemented?
Reply:
President,
About 20 000 tonnes of vehicle tyre waste are generated in Hong Kong every year, of which some are retreaded for reuse or recycled. Vehicle tyre waste can be processed to recover metals, cut and shredded into crumb rubber as raw materials for other products, or utilised as alternative fuel as a means of converting waste to energy.
The reply to the question raised by the Hon Frankie Yick is as follows:
(1) Statistics on vehicle tyre waste generation by weight and handling method each year from 2021 to 2023 are tabulated below. The figures show that the proportion of vehicle tyre waste being recycled and retreaded for reuse is increasing year by year. Statistics for 2024 are still under compilation.

(2) and (5) At present, tyres replaced during vehicle maintenance services undertaken by government departments are usually sent to contractors for retreading and reuse, or to recyclers for shredding and recycling. Vehicle tyre waste collected in public places by government departments and their outsourced service contractors is currently delivered to landfills for disposal. The relevant figures from 2021 to 2023 are tabulated below. Statistics of 2024 are still under compilation.
