Project title

Preparation of a feasibility study for hazardous waste management in Malaysia

Project description

For the US Trade and Development Agency, STELLA staff prepared the terms of reference for a Feasibility Study (FS) on hazardous waste management in Malaysia. The FS evaluated whether Kualiti Alam (KA), the 15-year hazardous waste management concessionaire selected by the Malaysian government, could use the plasma technology in their Waste Management Centre in Bukit Nanas. Plasma arc torches use electricity to generate extremely high temperatures (from 5,000 to 14,000 degrees Celsius) that disassociate organics into gases and melt inorganics into lava. During its mission in Malaysia, STELLA staff met with KA's executives who expressed strong interest in plasma and requested TDA's assistance. KA's Waste Management Centre in Bukit Nanas currently includes a hazardous waste storage facility and a hazardous waste landfill. A plasma plant would complement the upcoming 50,000 tons per year incinerator and would handle ash from the incinerator and wastes that cannot be incinerated. To prepare the terms of reference, STELLA staff reviewed the quantities and types of hazardous wastes generated in Malaysia and assessed current waste management practices. STELLA staff also estimated the capital and operation and maintenance costs of KA's proposed 80,000 tons per year Plasma Pyrolysis and Vitrification Plant. STELLA staff recommended that TDA finance a FS to assess the commercial viability of the plasma technology for hazardous waste treatment. TDA signed a $300,000 grant agreement with KA. A consortium of four US companies (Global Plasma System, Westinghouse, SAIC, and Ernst and Young) conducted the FS (under a cost-sharing arrangement) that resulted in a partnership between Global Plasma System and KA.
