Incineration and its implications: the need for a sustainable waste management system in Malaysia
This study examines the current global situations of incineration as a waste management method. The objectives are to reiterate that incineration is not a sustainable waste management system in this 21 st century in Malaysia. Though, the proponents of incineration are trying to convince us to accept it is the best solution to reduce the large quantities of waste generated in Malaysia. However, studies around the world has shown strong oppositions of incineration even though it is been touted as another source of energy generation. This is because its environmental externalities overwhelms its advantages as there is no economic sense in building a waste management system that has a limited time of existence in this age of sustainable development. Recycling and composting of waste has proven that of all waste management methods to be generally accepted as only options which we could use to turn waste into wealth. The argument that incineration is waste to energy does not hold water as the end justifies the means. It is being myopic and not making a right decision in this contemporary world sustainable development has become a buzz word.
Investigating the Standard Process of Incineration in Langkawi Island, Malaysia
American Journal of Environmental Sciences, 2014
Development activities and increasing urbanization have direct impact on solid waste generation, especially in municipalities of the developing countries, which poses a major challenge to the authorities. Many various technologies and strategies can be used in the field of garbage procedures. Incineration is a well-organized approach and tool to decrease the volume of waste and insist for additional landfill area. One of the important benefits of using the incineration is its ability to decrease a significant amount of waste combustibles by 80 to 95%. Controlling air pollution in the process of using the incineration poses a challenge for solid waste disposal. The data utilized in this article include personal interview of the experts handling the incineration process in Langkawi and personal observation. Secondary data obtained from the Ministry of Housing and Local Government was used to investigate the external air pollution from using the incinerator in Langkawi. The results showed, through the analysis of raw data with SPSS IBM 19 and Pearson correlation analysis and identify cluster of dendrogram generated by UPGMA, an external pollution minimum (p<0.05) between sampling sites inside the incinerator. The reasons for the difference are related to untimely and inappropriate opening of the combustion chamber door, exorbitance blowing and improper use of the installed air pollution control devices. The proper treatment of solid waste is very crucial, especially in Langkawi Island which is a tourist destination. The use of incinerator can enhance solid waste treatment, but only when the standard operating procedure is observed. Without properly observing the procedure, the use of an incinerator can cause more environmental and personal health issues like air pollution and the releasing of hazardous waste and clinical waste s into the landfill. These are some of the reasons that motivated this study to investigate the use of incineration in Langkawi Island.
Incinerator in Malaysia: Really Needs?
Increasing population, tremendous urbanisation growth and rapid economic growth influence directly the Municipal Solid Waste generation in Malaysia. Thus, incineration is one of the considered methods of waste treatment that is quickly attracting the municipal authorities' attention in this country because incineration solves many of the problems so common to other methods of municipal garbage disposal. The advantages of incinerator plant including will not have rodent problems, produce bad odours, require large plots of land or require many employees. Therefore, incineration will become one of the best practical choices in treating municipal solid wastes in Malaysia in the near future due to the various constraints such as limited landfill sites, immature recycling and biological treatment infrastructures. However, the advantages and disadvantages of this method need to study deeply and properly before installing such system in Malaysia.
Exponential population growth in cities have generated huge amounts of municipal solid waste (MSW). This includes Melaka which in addition has experienced a rising number of tourists over recent years. The two factors combined have brought to the production of approximately 1200 tonnes of waste per day. Landfilling is the general method of disposal but has brought with it challenges of insufficient territory. To address the issue, this study suggests the use of incineration technology as an alternative method. Experts' opinions are generated regarding the suitability of implementing the technology in Melaka. A qualitative method is used by interviewing top management of the secretariat of Melaka Green Technology Council and Melaka Green Technology Corporation. PESTLE analysis approach is incorporated as an explorative research tool. The findings showed that Melaka has the capabilities of implementing the incineration technology on a large scale.

Globally, the most used waste treatment method is landfilling, although (improper) landfilling, which is typical for developing countries, has no material or energy recovery possibility compared with other treatment methods. In Indonesia, open dumping on final disposal sites covers most of the treated waste, which is an even worse method than landfilling in terms of environmental issues. The main objective of this article is to evaluate the feasibility of the waste-to-energy solution/waste incineration approach for proper and sustainable waste management in Bandung. A big issue of municipal solid waste is the organic portion of waste, as most emissions and pollution come from organic waste and improper handling. A specific objective is to conduct the risk analysis of an incineration plant model and to compare the environmental impact of incineration vs landfilling. The input data for the assessment will be obtained from the laboratory analyses of solid waste samples collected from t...

The incineration of municipal solid waste (MSW) effectively reduces waste and has a side product, such as electricity. The waste-to-energy (WTE) power plant in Bantargebang is the first national pilot plant facility in Indonesia using moving grate incinerator (MGI) technology, with a 100 tons/day design capacity and a maximum design of electricity power output of 750 kW. The main challenge of WTE in Indonesia is high moisture content (MC) and unsorted waste. Hence, it is imperative to include the pre-treatment facility through waste drying and sorting. In this work, over 241 working days from January to December 2022, approximately 15,451.35 tons of MSW (averaging 70.55 tons/day) have been incinerated at an average temperature of 613.8 o C. Waste pretreatment alleviates waste MC from 20.13% to 8.59%. This process achieves a significant waste mass reduction of 81.52-96.50%. In addition, the system generates superheated steam at maximum values of 5000 kg/h, 340 o C, and 38-39 barA. The total electrical energy generated (956.04 MWh) is used to supply the electrical energy demand of the internal plant operation (1368.78 MWh). Moreover, the wastewater and flue gas in this WTE have successfully been processed by the pollution control systems to meet national standards. The fly and bottom ash from MSW incineration have proven harmless and suitable for construction material or cement admixture. This work conclusively shows that WTE Bantargebang provides positive implementation in almost all aspects, encompasses a significant amount of waste reduction, satisfying incineration performance, a significant amount of electricity generated, and the environmental performance does not harm the surroundings. Related to the performance deficiencies found is expected can be a valuable input for WTE development in Indonesia.
Case preliminary study for municipal waste incineration
Human activities in huge agglomerations generate important amounts of domestic waste and waste water that count on the municipality administration to be ecologically resolved. In this paper, it is proposed incineration unit architecture for removing the mud resulted from waste water treatment, completed with ordinary human generated pollutants, collected as solids. From basic physical principles, as mass balance, thermal balance, thermodynamic cycle for energy recovery in mechanical or electrical form and thermal heat energy indirect exchange, there is done an estimation of the energetic efficiency and energy rate produced.
Municipal solid waste management in Malaysia: Practices and challenges
Waste Management, 2009
Rapid economic development and population growth, inadequate infrastructure and expertise, and land scarcity make the management of municipal solid waste become one of Malaysia's most critical environmental issues. The study is aimed at evaluating the generation, characteristics, and management of solid waste in Malaysia based on published information. In general, the per capita generation rate is about 0.5-0.8 kg/person/day in which domestic waste is the primary source. Currently, solid waste is managed by the Ministry of Housing and Local Government, with the participation of the private sector. A new institutional and legislation framework has been structured with the objectives to establish a holistic, integrated, and cost-effective solid waste management system, with an emphasis on environmental protection and public health. Therefore, the hierarchy of solid waste management has given the highest priority to source reduction through 3R, intermediate treatment and final disposal.
