CHAPTER 5 Project Description ENVIRONMENTAL IMPACT ASSESSMENT FOR PROPOSED CLINICAL WASTE TREATMENT PLANT AT TELUK KALONG INDUSTRIAL ESTATE, KEMAMAN, TERENGGANU FOR RADICARE (M) SDN BHD CHAPTER 5 – PROJECT DESCRIPTION Chapter 5 PROJECT DESCRIPTION 5.1 Introduction This chapter describes the Project location, components and layout as well as the Project activities. The Project management structure and implementation schedule are also presented. 5.2 Project Location The Proposed Project site is located at PT 9653, Telok Kalong Industrial Estate (TKIE), Kemaman, Terengganu. The site covers an area of 21,000 m2 (about 5.2 ha) approximately 169 km southeast from Kuala Terengganu township and about 6 km from Chukai town. The Proposed site is a vacant land surrounded by industries mainly related to chemical and petrochemical industries. The Project location map is as shown in Figure 1.2.1. Approximate coordinates of the Project area are tabulated in Table 1.2.1. 5.3 Project Components and Layout The Project involves planning, construction, installation and operation of a counter-current rotary kiln type incinerator with a capacity to treat 15 MT/day x 2 lines of clinical waste per unit of incinerator. The project shall include 2 units of incinerator which will be developed in 2 phases. This counter-current rotary kiln type incinerator is developed by BIC Systems Asia Pacific Pte Ltd. Generally, the main components of the incinerator plant facility include waste reception and storage, waste combustion, gas cooling, air pollution control and ash receiving and storage system, truck and bin washing system. Also included is the industrial effluent treatment system (IETS) to treat the wastewater from the bin and truck washing. Figure 5.3.1(a) shows the layout of the Project components that consist of proposed incinerator area, storage areas (for clinical waste, chemicals and ash), administration building, bin washing/ disinfection area and the IETS area. The Project components are elaborated in the following sub-sections. 5.3.1 Clinical Waste Reception Area This area is allocated to house the unloading and weighing of received clinical waste. It is for temporary storage before further feeding process in the system.

As a safety measure, a cold room shall be provided to accommodate abnormal operation events such as plant shut down, maintenance and over generation of CW, probably from disease outbreak etc. At the end of the day, untreated CW will be stored in the cold storage area before being processed during the following day. There will be cold room stores which can accommodate 250 tonnes per month and able to store untreated wastes up to 16 days, temperature of below 6 °C. 5.3.3 Infrastructures and Utilities 5.3.3.1.1 Water Supply Water supply requirement for ancillary facilities is estimated at 250m3/month (average). Among relevant components are water supply distribution pipe, water pump house and storm water drainage. 5.3.3.1.2 Electricity Electricity supply requirement for the incinerator is estimated about 50 kWh. Meanwhile for the ancillary facilities the electricity requirement is 80 kWh (average). 5.3.3.1.3 Internet Network The Project site requires internet speed of 4Mbps for computer networking. 5.3.3.1.4 Storm Water Drainage System Storm water drainage system shall be prepared around the Project boundary. Storm water within the Project area will be channelled to perimeter drainage system and it will be discharged to the existing drainage system available within the Telok Kalong Industrial Estate. 5.3.3.1.5 Other Facilities Sewerage treatment plant shall be provided with compliance to Standard B of the Environmental Quality (Sewerage) Regulation 2009.The STP shall cater for about 30 personnel. The discharged from the septic tank shall be to the nearest existing drain. Detail for the intended types of sewage treatment system is attached in Appendix 5.3.3. Other facilities to be included are main office, workshop, scheduled waste store, general room and staff room. 5.3.4 Incinerator Plant The incinerator plant will be divided in 2 phases, Phase 1 and Phase 2. For each phase the proposed incinerator system is for an operation capacity of 15 MT/day (625 kg/hr) utilising rotary kiln type with Flue Gas Thermal Oil (FGTO) heat exchanger. However, the design capacity is higher, at 18 MT/day (750 kg/hr). Designed plant life is 20 years with thermal capacity 3,750,000 Kcal/hr or 15,750 MJ/hr. An opened but roofed pad area will accommodate for combustion / incineration process block. Components of the incinerator plant are summarised in the following subsection. Figure 5.3.1(a) shows the layout of the Project components that consist of incinerator area, storage area (for clinical waste, chemicals and ash), administration building and bin washing/ disinfection area.

Feed hopper height is 5 meters, from where the waste is introduced. Suitable level indication/switches are incorporated. Suitable weight monitoring system is incorporated. The bottom of the hopper that feeds to the incinerator has interlocks to protect the hopper from the high temperature in the incinerator. The bottom of the hopper is designed sufficiently strong to receive impact from the waste dropping and not bend over time. Dumping the waste from the feed hopper to the incinerator is monitored by the interlock system, so that the incinerator is not overloaded or running without feed. Feeding ram design is trouble free and very versatile. A scraper will be installed to prevent waste from adhering onto the ram. The ram has improved stiffeners to prevent it from bending over time. Cooling water injection is foreseen in the feeding area.
