The 2012 Audit Report revealed that only one out of the four waste incinerators is up and running.
Out of the four projects, only one is in operation. Another two projects have been completed but not in operation yet, while the fourth was still under construction.
Under the Ninth and Tenth Malaysia Plan, a total of RM199.09 million ut of the RM337.45 million allocated by the Federal Government was spent on the construction of the incinerators.
The ministry built incinerators using the combustion technology proposed by XCN Technology Sdn Bhd in Pulau Langkawi, Pulau Pangkor, Cameron Highlands and Pulau Tioman.
The audit finding proved that the all the incinerators were not completed during the scheduled period and only one was ready within the extended deadline.
Another two incinerators were completed between 46 days and 104 days after the extended deadline while one is still under construction.
Even the Pangkor incinerator could not operate at the set temperature range and is inefficient.
There were also flaws in the documents on the plant operation and maintenance contract.
The report also revealed that there were design flaws resulting in the incinerator not operating at optimal level.
Bad management was also due to non-compliance of the Enviromental Impact Assesment (EIA), Occupational Safety and Health Act and the Factories and Machinery Act.
The National Audit Department advised the ministry to provide an effective management of solid waste.
The audit also recommended raising public awareness on the importance of separation of solid waste.
The ministry was urged to improve the solid waste treatment so that autogenous combustion could be achieved in a more efficient manner.
