Bukit Tagar Sanitary Landfill
Executive Summary

  Tai Hoe Resources made a tremendous achievement in line with our mission for excellence as we enhanced our capabilities as an environmental solutions provider. In the year 2010, one of the key highlighted projects that was taken on and completed; was the design of landfill gas (LFG) extraction, collection and flaring system at Bukit Tagar Sanitary Landfill. This project was made possible together with our technology partner, Nanjing Yuanfeng Energy Development Co Ltd of Beijing, China.

  The project spans for 11 months from design stages to complete handover. There were three components: Horizontal Extraction Wells (Wells), Transfer Pipes (TP) and Flaring Plants and Mechanism (Flaring).

  The Wells structures were gas pipes and leachate pipes. The pipes were horizontal in nature, where it is deemed to be more optimized and able to collect significant amount of LFG. LFGs produced from bio-chemical process were collected in the pipes and transferred. By having the leachate pipes in the wells, this will aid the leachate management in the landfill.

  LFG collected was transferred in a TP system where it is purified, removing dust and water. The utilization of a blower is to create negative pressure to move the gas. Compressed gas is unsuitable as it will create rise in temperature. This is necessary to obtain the optimum nature of the LFG for the flaring system to work efficiently and maintain plant integrity.

  The Flaring system consists of filters, valves, roots blower, instruments of measurement ignition system and flare stacks. The system measure the composition of the LFG to ensure methane and other contents are in the right percentage for the efficient flaring process.

  Key capabilities proven by Tai Hoe Resources were the organization of the project, skills obtained during construction process and technology transfer. This project was a milestone in Tai Hoe Resources history as environmental solutions provider.

Project Overview

  Bukit Tagar Sanitary Landfill (BTSL) is a project under Malaysia’s Local Government and Housing Ministry (Kementerian Perumahan dan Kerajaan Tempatan). It is operated by KUB-Berjaya Enviro Sdn Bhd (KBE), a joint-venture of KUB Malaysia and Berjaya Group. Within this project, KBE aims to provide environmental solutions consist of solid waste management and to be the pioneer of the development of green energy technology.

  In our mission as a partner in nation building, Tai Hoe Resources strive to take up the challenge to give a great contribution to this purpose, while enhancing our capabilities. Hence, we undertook the project with great pride, of the Design, Construct and Commission of Landfill Gas (LFG) Extraction and Flaring System project works for Phase 1 at BTSL.

  The project took 11 months to complete and have the system fully operational. Together with our technology partner, Nanjing Yuanfeng Energy Co. Ltd (Partner), we develop an extraction and flaring system. The alignment of the wells used is horizontal in nature, where our own design studies with our Partner shows that this alignment can extract a better number for volume of gas extracted. Other showcase of our design is in our transfer pipe system where we incorporate connections for future link up for potentially new construction of the extraction wells.

  We also have add-in for landfill leachate management by including leachate pipes in the wells. Hence, we have dual system of managing the release of methane gas and leachate in landfills.

  In our design, we have allow in the future that the extraction of LFG is to be harvested that could serve to produce fuel for electricity power generation.

  Tai Hoe Resources is very proud to say that we achieved and enhanced what we do best in our civil engineering knowledge and skills, of digging up trenches, earthworks, pipe laying and others. But in producing our own design and built work, we have taken a big leap in the milestone of our organization.
