Public Fill

Public fill arises from construction, excavation, renovation, demolition and road works. Comprising of rocks, concrete, asphalt, rubbles, bricks, stones and earth, public fill is suitable for reuse in reclamation and site formation. Hard materials such as rocks and concrete can be recycled as aggregates for concrete/asphalt production or as granular materials for road sub-base and drainage layers, etc.

Management Strategy

The strategy to manage public fill comprises three major tasks - reduce, reuse and recycle. Concerted efforts in the construction industry are required in the following areas -

(a) Reducing

public fill at source through better planning, design and construction management to reduce the overall volume of public fill produced. Government departments are required to prepare management plans for public works projects to critically examine alternatives to reduce public fill produced during design stage and to monitor its implementation during construction.;

(b) Separating

out waste such as timber, paper, plastic etc. to prevent public fill that could be reused or recycled from going to landfills. Contractors of Government works contracts are required to prepare and implement waste management plan to carry out on-site sorting and implement a trip-ticket system to ensure that public fill and waste are delivered to the appropriate reception sites/facilities.

(c) Reusing

public fill in reclamation, site formation and other earth filling works where possible. Whilst sustaining the overall development of the territory, the construction industry has generated large amount of construction and demolition materials from construction, excavation and demolition works every year. About 90% of these construction and demolition materials are recyclable or reusable inert materials, which are commonly known as public fill, and can be used as fill materials in reclamation, site formation and other earth filling projects. We provide reception facilities to receive surplus public fill arising from the construction industry. The surplus public fill is temporarily stored in the fill banks, pending opportunity for reuse. This not only helps to combat fly-tipping but also serves as a stable source of public fill for future reclamation projects. In recent years, local projects had only been able to reuse a portion of surplus public fill generated. As a result, it is necessary for us to deliver part of the surplus public fill to designated area in the Mainland for beneficial reuse.

Placing order and collection of public fill for reuse in construction works are simple. Relevant procedures are summarized in the following flow chart.

Public Filling Service

The beneficial use of public fill provides an economical source of fill materials for reclamation and earth-filling projects and also helps preserve the precious landfill space in Hong Kong, which would otherwise have to be used for the disposal of such material. Marine mud, household refuse, plastic, metal, industrial and chemical waste, animal and vegetable matter and other unsuitable materials are not allowed to be disposed of at any public fill reception facility.

Statistics of construction and demolition materials received at the Public Fill Reception Facilities and Landfills

The Public Fill Committee (PFC) is responsible for implementing measures to promote avoidance, minimization, re-use and recycling of construction and demolition material. It also oversees the management of public filling operations and facilities. In addition, the PFC produces and circulates the Forecast of Public Fill Generation and Demand Tables and designates the public fill reception facilities for public works projects. The Secretariat of the Committee is provided by the Fill Management Division.

For further information on Public Filling Service, please contact Senior Engineer / Strategy 2 of Fill Management Division mtleung@cedd.gov.hk.

Dumping Licences         

Truck owners shall apply licences for dumping public fill within the public fill reception facilities from Fill Management Division. The licences are free of charge, valid for three years and renewable. (Normally, it takes 1 and 2 working days for issue of electronic and paper licences respectively.)

Trip-Ticket System

The Development Bureau has promulgated under Development Bureau Technical Circular (Works) No. 6/2010 the policy to implement a trip-ticket system in public works contracts for the proper disposal of construction and demolition materials at public fill reception facilities or landfills in order to minimise the incidence of illegal dumping. In the planning stage of a contract, the project officer shall seek confirmation from the Public Fill Committee (PFC) through the Secretary of PFC as to whether public fill reception facilities will be available for the disposal of public fill generated or shall seek confirmation from the Director of Environmental Protection as to whether landfills will be available for the disposal of non-inert construction and demolition materials generated.
