Safety Moment
• The IWMF Project will strongly focus on safety throughout the complete lifecycle of the project by:
• Building a Strong Safety Culture amongst ALL Stakeholders
• Ensuring Responsibility for and Leadership in Safety
• Exceed the “Business as Usual” Approach to Safety; let us all make a difference !!
• Safety Initiatives Associated with the Project: Introducing a Safety Incentive and Disincentive Scheme for all Contractors
• Join us in our Goal to make IWMF an outstanding example of the implementation of a major project with a Strong Safety Culture and Outstanding Safety Performance

We aim for ZERO HARM
and Promote Health and Safety for Life of Everyone at Work and Outside Work
We Strive to achieve our goal of Zero Harm by
consistently implementing:
Site and Task Specific Processes; Empowering All Individuals to Stop Unsafe Practices; Safety Training & Coaching; Leading by Example, Implementing Safety Rewards & Recognition; Developing a Positive
Safety Culture; Ensuring Visibility of Leadership; Communicating Safety Accountability at All Levels; Actively Reporting Incidents, Near Misses
and Unsafe Behaviors and Conditions; Adopting a “See Something: Say Something” Culture; Designing for Safety and Identifying Hazards
Thus continuously improving to be the Best –in- Class
No Task is so Important that it Cannot be Done Safely

Waste-To-Energy Facility: Incinerable Waste
• Facility to treat Incinerable Waste with Advanced Moving Grate Technology • Goal: To ensure high volume reduction in waste and maximise energy and resource recovery
• Key Criteria for Technology Selection
• Commercially available
• Volume reduction: Min 90%
• Phase 1 (2900t/d; 4 lines) and 2 (2900t/d; 4 lines) Reliable Capacity = total 5800 t/d (8 lines)
• Key design features: • State of the art furnace and boiler design
• Innovative energy system leading to high power production efficiency
• Wet flue gas treatment system leading to clean air emissions
• Reliability and Robustness: 8000 hours per year availability (approx 90%)
6
IWMF: Powering a Green Singapore
Project Innovation – Improved Power Production • IWMF will be able to achieve high overall plant thermal efficiency (~ 28%) through:
• Optimised combustion process including grate and boiler designs, SNCR
• Increased steam parameters 370C/35 bar 440C/55 bar
• Use of external biogas superheaters to boost steam parameters from 440 C/55 bar 480 C/55 bar
• Optimised Air Cooled Condenser System
7
Annual power production of IWMF will be ~ 2 Million MWh
Can power more than 300,000 apartments (4-room apartments)
IWMF: Powering a Green Singapore
Project Innovation – Minimise Environmental Impact
• IWMF will be designed with Catalytic Baghouse Filters and Wet FGT system to produce clean air emissions to exceed current Singapore Air Emission Requirements and meet or exceed EU Requirements
• This will allow IWMF to future-proof against further tightening of air emission requirements
• The Wet FGT will allow IWMF to minimise solid residue disposal as less chemicals are required
• This will extend the lifespan of the existing Semakau Landfill

RECYCLABLES
13
Materials Recovery Facility (MRF) • Materials Recovery Facility (MRF)
• Co-mingled dry recyclables received from households including apartments, condos and also from commercial premises
• Goal: High sorting efficiency, high product quality, minimisation of manpower and reduced land-take
• Technology based on advanced automatic systems to sort metals, glass, paper, cardboard and plastics to produce high quality, low contamination output.
• 250T/d total capacity (likely to be equipped with trommel screens, ballistic separators, magnetic separators, eddy current separators, wind sifters, near- infrared (NIR), balers etc. )
14
Food Waste Treatment Facility (FWTF) • Facility to treat source-segregated food waste to produce high
quality bio-pulp for co-digestion with used water sludge at Tuas WRP • Food Waste: collected from restaurants, hawkers centres, supermarkets,
canteens, flight kitchens etc. (not from households)
• Goal: To recover more energy from food waste via co-digestion with used water sludge
• Well-proven technology based on screw press or other proven technology with effective odour control and minimal manpower intervention High quality bio-pulp with rejects sent to WTE bunker
• 2 lines x 200 t/d
16
IWMF: Powering a Green Singapore
Sludge Incineration Facility (SIF) • Goal: Treatment of TWRP’s dewatered sludge and provide steam to TWRP
for use in Biosolids and Greasy Wastes processing
• Dewatered sludge (25 to 28%DS) conveyed from TWRP to SIF
• Fluidised Bed Technology has been selected due to extensive track record on used water sludges
• 2 x 400 t/d at 28% DS FBI’s for treatment of dewatered sludge with pre-drying to around 40% DS prior to feeding to FBI. Boilers, Baghouse Filters and Wet FGT that meets international standards

• A single PQ document has been prepared in Draft and is under review by NEA with target date to release on GEBIZ in July. The PQ document
allows the tenderers to PQ for EPC Tender 1 and/or EPC Tender 2.
• EPC tenderers must have the necessary expertise and experience in the design, engineering, procurement, construction and commissioning of
the facilities.
• The PQ document has specific track record and financial strength requirements for the main EPC Contractor as well as track record requirements
for the key technology areas in each Package.
• It is likely that the main EPC Contractor applicants will be a Consortium of companies. Any consortium must be Unincorporated and Joint and
Several.
• Each Applicant whether a single company and in the case of a Consortium, all members of the Consortium, must be BCA Registered ME11 L6 or
CW02 A1. The Consortium Lead shall be ME11 L6.
• A BCA “Conditional Registration” process to obtain ME11 L6 (Limited) will be put in place for international companies who currently do not hold
BCA registration in ME11 L6.
