Following is a question by the Hon Judy Chan and a written reply by the Secretary for Environment and Ecology, Mr Tse Chin-wan, in the Legislative Council today (April 30):
 
Question:
 
     Under the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal (the Convention), member countries (Parties) are expected to treat and dispose of wastes as close as possible to their place of generation and to prevent and minimise the generation of wastes at source, and waste lead-acid batteries are hazardous waste regulated under the Convention. China is a Party to the Convention, the Convention is therefore applicable to Hong Kong as well. It has been reported that at present, most of the waste lead-acid batteries in Hong Kong were exported to other places (including Korea) after treatment, and those recycled locally only accounted for a small portion. In this connection, will the Government inform this Council:
 
(1) of the quantity of waste lead-acid batteries generated in Hong Kong in each of the past three years, as well as the respective quantities of waste lead-acid batteries preliminarily processed locally, exported to overseas advanced facilities for recycling (with a breakdown by export areas) and recycled locally;
 
(2) of the respective maximum annual treatment capacities of the facilities for (i) preliminary treatment and (ii) recycling of waste lead-acid batteries in Hong Kong;
 
(3) of the details of projects relating to waste lead-acid batteries subsidised by the Recycling Fund in the past three years (including but not limited to the amount of subsidy granted for each project and the content of the subsidy);
 
(4) of the current progress of the implementation of the Producer Responsibility Scheme on waste lead-acid batteries, as well as the recovery target for local waste lead-acid batteries after the implementation of the Scheme; and
 
(5) whether the authorities have formulated a contingency plan to cope with the situation where the collection of treated waste lead-acid batteries exported from Hong Kong will be suspended in the event of policy adjustments by Korea or other places; if so, of the specific proposals; if not, the reasons for that?
 
Reply:
 
President,
 
     Handling of waste lead-acid batteries is strictly regulated under the Waste Disposal Ordinance, and the Waste Disposal (Chemical Waste) (General) Regulation including registration as chemical waste producers, applications for chemical waste collection and disposal licences, reporting the quantities of waste lead-acid batteries produced, collected and disposed of, and regulating the transboundary movements of waste lead-acid batteries according to the Basel Convention (the Convention).
 
    Any person intending to export waste lead-acid batteries for recycling should apply to the Environmental Protection Department (EPD) for an export permit. Prior to issuing the permit, the EPD will obtain written consent from the relevant authority of the concerned state of import to ensure that the waste lead-acid batteries will be transported to an approved recycling facility in the destination location for recycling in an environmentally sound manner.
 
     The Convention encourages the Parties of the Convention to dispose of controlled waste within the country of origin as far as possible, but it does not prohibit the import or export of such waste under certain conditions, including that the state of import needs the waste as a raw material for recycling or recovery use. Currently, the waste lead-acid batteries exported from the Hong Kong Special Administrative Region comply with the above principles. Under the permit control system, approval from the competent authority of the concerned state of import must be obtained prior to the export of waste lead-acid batteries, which must be recycled in facilities equipped with processing capacity in waste lead-acid batteries.
 
     The EPD will continue to combat illegal collection and disposal of waste lead-acid batteries, and promote proper disposal of waste lead-acid batteries and the relevant legal requirements to the trade.
 
     The reply to the question raised by the Hon Judy Chan is as follows:
 
(1) and (2) Currently, there are approximately 700 000 fuel-powered or gas-powered vehicles in Hong Kong, amounting to an estimation of around 3 000 tonnes of waste lead-acid batteries generated annually. In addition to other applications including uninterruptible power supply systems (e.g. data centres and emergency lighting), non-road mobile machineries (e.g. forklifts), vessels, and emergency generators in industrial and commercial buildings, an additional 3 500 to 4 000 tonnes of waste lead-acid batteries are generated each year. Thus, it is estimated that a total of 6 500 to 7 000 tonnes of waste lead-acid batteries are generated in Hong Kong annually. In recent years, the number of electric vehicles in Hong Kong has been steadily increasing. There were 110 014 electric vehicles in Hong Kong in 2024, representing about 12.2 per cent of the total number of vehicles. As newly launched electric vehicles no longer use lead-acid batteries, it is expected that the quantity of waste lead-acid batteries generated will gradually decline in the future.         
 
     Currently, there are eight licensed disposal facilities for disposal of waste lead-acid batteries, seven of which conduct preliminary treatment such as sorting, insulation, and packaging before exporting the waste lead-acid batteries to overseas facilities for recycling. According to the capacity stipulated in their licences, these seven facilities can collectively process up to approximately 42 000 tonnes of waste lead-acid batteries annually. Another licensed facility located at the EcoPark in Tuen Mun processes waste lead-acid batteries into lead bullion by dismantling waste lead-acid batteries into lead grid and lead paste by means of high temperature smelting. The maximum annual disposal capacity (for lead bullion production) stipulated in its licence is about 8 000 tonnes.
 
     In the past three years, the quantities of waste lead-acid batteries treated locally and exported overseas are listed as follows:
 

Year	Quantity of waste lead-acid batteries delivered to local licensed disposal facilities for preliminary treatment and export to overseas recycling facilities (Note)	Quantity of waste lead-acid batteries disposed of by the local recycling facility
2022	5 790 tonnes	765 tonnes
2023	4 355 tonnes	853 tonnes
2024	5 096 tonnes	1 102 tonnes

Note: All licensed disposal facilities holding export permits for waste lead-acid batteries exported waste lead-acid batteries to Korea for recycling.
 
(3) Over the past three years (i.e. 2022 to 2024), the Recycling Fund approved a total subsidy of about $1.03 million for seven waste lead-acid batteries recyclers. The approved funding was to subsidise the purchase of equipment, such as packaging machine, scissor lift and electric pallet truck for enhancing their productivity, and provide a one-off subsidy to frontline recycling staff to help the recycling industry to cope with the COVID-19 epidemic.
 
(4) The Government has introduced the Promotion of Recycling and Proper Disposal of Products (Miscellaneous Amendments) Bill 2025 (Amendment Bill) to the Legislative Council on April 2 this year to establish a common legislative framework for the producer responsibility schemes (PRSs) applicable to different products. After the passage of the Amendment Bill, we will extend PRSs to more products (including lead-acid batteries) as and when appropriate by means of subsidiary legislation.
 
     The EPD has conducted consultations on the proposed PRS on lead-acid batteries from June 2023 to April 2025. We hitherto have met with more than 40 companies or organisations including trade associations of automotive batteries and tyres industry, traders of automotive parts, suppliers of uninterrupted power supplies, medical devices and forklifts, as well as engineering contractors and recyclers, with a view to considering the trade's opinions when drawing up the implementation details. We will maintain a close communication with the trades and take into account their views for the sake of fine-tuning the operational details of the scheme as appropriate, including setting appropriate recycling targets in light of the prevailing circumstances.
 
(5) After proper treatment of waste lead-acid batteries, valuable lead materials can be recovered, which have considerable value in the international recycling market. Therefore, there is a market for purchasing waste lead-acid batteries for recycling. Apart from Korea, many countries including Poland, the Czech Republic, Spain, Mexico, Greece, and Canada, possess the capability to process waste lead-acid batteries and import them from other places for recycling purposes. The local recycling facility located at the EcoPark is also capable of treating locally generated waste lead-acid batteries. Therefore, even if certain places adjust their policies and cease importing treated waste lead-acid batteries, the market is still capable of handling them.
