Material Aspects Mr. Benny Au 10 November 2012 Material aspects is about reduce material consumption, promote recyclable materials and waste management ~ • Material reuse • Standardized design • Flexibility design • Renewable material • Sustainable timber • Ozone depleting substances • Waste management Ecological Footprint • Definition: The amount of biologically productive land and sea area needed to regenerate the resources human population consumes and to absorb and render harmless the corresponding waste • If the whole world would consume resources at the rate Hong Kong does presently, we would need the equivalent of TWO PLANETS to satisfy those needs • REDUCE, RE-USE, RECYCLE!!!

BEAM Plus NB Ma 11 Landfill sites in HK 3 strategic landfills are: • West New Territories (WENT) Landfill (in Nim Wan, Tuen Mun); • South East New Territories (SENT) Landfill (in Tai Chik Sha, Tseung Kwan O); • North East New Territories (NENT) Landfill (in Ta Kwu Ling) from EPD website Public Fill in HK Public filling areas, public filling barging points, public fill stockpiling areas, fill banks and C&D material recycling facility are managed by the Civil Engineering and Development Department to accept 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. The strategy to manage public fill comprises the followings: Reducing public fill at source through better planning, design and construction management to reduce the overall volume of public fill produced. Separating out waste such as timber, paper, plastic etc. to prevent public fill that could be reused or recycled from going to landfills. Reusing public fill in reclamation and site formation works where possible. However, this is becoming increasingly difficult because of the drastic reduction of reclamation and site formation works. Recycling suitable public fill as recycled aggregates Public Fill in HK Requirement: Using no Chlorofluorocarbon (CFC)-based refrigerants in HVAC&R systems.
