OBJECTIVE Ensure that the design, installation and facilities waste disposal and
recycling are such as to reduce the risk of odours entering occupied
areas or public areas.
CREDITS ATTAINABLE 1
PREREQUISITES Compliance with the Building (Refuse Storage Chambers and Material
Recovery Chambers and Refuse Chutes) Regulations.
CREDIT REQUIREMENT 1 credit for the provision of a de-odourising system in all refuse collection
rooms and chambers.
ASSESSMENT The Client shall submit details of the de-odourising systems, noise
control abatement system and fire protection provisions. The system
shall comply with those recommendations contained in PNAP No. APP-
35 [1] in respect of refuse storage and recovery chambers appropriate to
the given circumstances.
The provision of a purpose-designed automated/mechanical system for
waste disposal is deemed to meet the requirements.
BACKGROUND Where refuse contains large amounts of food and other organic waste
there are potential odours and health problems if refuse is not well
contained from the points of disposal by users to the place of final
collection. Automatic systems are available to isolate refuse from users.
REFUSE CHAMBERS Where a centralised ventilation system is adopted, a single air purifier
may be installed before final discharge into the atmosphere. Alternatively
where there is no particular odour problem a mechanical fan coupled
with a particulate filter at each RS&MRR/MRC may be considered. The
main exhaust outlet for a centralised ventilation system should be
located at upper roof level away from other buildings; however in the
case where the building is surrounded by taller buildings the discharge
may be located at the main RS&MRC.
The noise level of the system should conform with the Technical
Memorandum [2] published under the Noise Control Ordinance (Cap
400). Fire dampers should be provided if the system has exhaust grilles
and ducting at each floor.
Air purifying devices such as ‘Chemical Air Scrubber’, ‘Bio-oxygen
Generator’, ‘Photo-oxidation Generator’ or other appropriate devices
should be provided within a RS&MRC.
