• Calculating Waste
Company Background
Incorporated in 1998, Putrajaya
Perdana Berhad is an investment
holding company and is recognised
as one of Malaysia ’ s most
innovative and reliable construction
groups.
It has successfully delivered several
prominent award winning and large
scale projects on a turnkey design-
and-build basis as well as pioneering
energy efficiency in construction.
PPB’s Green Efforts
We have always held this beliefthat putting a stop to globalwarming and climate change isjust as important as ensuring ahealthy bottom line. In the withthis, we have since 2002, made acommitment to ensure energyefficiency, and now, green in ourprojects.
List of Green Buildings undertaken by PPB
PPB is the LEADER in Designing & Constructing Energy Efficient & Green Buildings.
1. We built the LEO (Low Energy Office) Building for the
Ministry of Energy, Green Technology & Water
(KeTTHA), a 2006 ASEAN Energy Award Winner
3. We built the HQ for Suruhanjaya Tenaga, a Green Mark
and GBI Platinum certified building.
2012 : ASEAN Energy Award Winner
2012 : Emerson Cup for India & SEA (Champion)
2013 : ASHRAE Technology Award (2nd Place)
2013 : Green Apple Award
Energy Policy Maker
Energy Sector Regulator
ENERGY EFFICIENT & GREEN BUILDINGS
2. We built the GEO (Green Energy Office Building)
(formerly known as ZEO) for Pusat Tenaga Malaysia
(PTM).
GEO is Malaysia’s 1st GBI certified green building

• Develop a strategy to reduce and manage
waste
• Assign a Coordinator to implement, monitor
& report
• Identify & estimate the types of waste (
think of reducing waste measures, reuse and
recycle)
• Provide method statement for segregation
of waste during construction.
• Provide list of construction haulers and
recyclers to redirect waste.
• Indentify handling & transportation
procedures
Challenges of implementing Construction Waste Management
Challenges of implementing Construction Waste Management
Challenges of implementing construction waste management
Challenges Action Plan
Lack of education & awareness • Training on awareness on staff and site team
Upfront cost • Allow in tender budget
• Cost savings from better managing the material
supply/storage & recovery/disposal
Insufficient environmental officer • Training
• Appoint a designated person
Challenges of implementing construction waste management
Challenges Action Plan
Resistance to change to adopt the
eco-friendly construction practices
• Company policy and objectives
• Sub contractual requirement
•3Rs•ISO 14001
Challenges of implementing construction waste management
Challenges Action Plan
All relevant requirements for the specific ratings of Green Buildings shall be complied
• Adopt the GBI guideline : provide dedicated areas where on
site sorted waste material can be stored for recycling
• Adopt the GBI guideline : Recycle and/or salvage ≥ 50% (75% for 2 points) volume of non-hazardous construction debris.
Challenges of implementing construction waste management
Challenges Action Plan
Limited space to provide waste bin for segregation
• Early planning i.e. put into the PQHSE Plan
Sourcing waste contractors • Preplanning
Ditto recyclers e.g.. Some manufacturer s refuse to take back timber pallet
• Establish the contractual agreement
• Carry out 3R effort internally
Handling, monitoring & recording • Have standard CWMP & work instructions
/ practices and reports.
Sample of GBI Report by Contractor
•Waste Disposal
- 3Rs: reduce, reuse & recycle.
During Construction
Dedicated area and storage
for collection of non-
hazardous materials for
recycling. Make
arrangement with licensed
waste collector to provide
segregation bins for metal,
tiles, timber, concrete,
glass, bricks and plastic.

•Use precast elements
•Good quality work

Challenges of implementing Construction Waste Management
•Reuse excess concrete
for concrete barrier, lintol &
wheel stopper; concrete
waste e.g.borepile cutoffs
reused for logistic road.

• Return of timber pallet & container for reuse
Challenges: Segregation of waste by types for ease of recycling
•Returned timber pallet

•Transfer usable
plywood and timber to
other project site for
reuse•Sell paper box to recycler

Challenges of implementing Construction Waste Management
GREEN PRACTICES: Calculating Construction Waste
Calculations
1. Calculations are based on the amount of waste diverted from landfill or
incineration compared with the total amount of generated waste at site.
2. Convert all materials to either weight or volume to calculate the
percentage. Exclude excavated soil and land clearing debris.
3. Hazardous materials should be excluded from calculations and should be
disposed of accordingly to relevant regulations
GREEN PRACTICES: Calculating Construction Waste
Material Density (lbs/cy) Density (kg/m3)
Steel 1,000 590
Wood/timber 300 180
Rubble 1,400 830
Mixed Waste 350 210
Cardboard 100 60
Gypsum wall
board
