Identification of the Municipal Solid Waste Characteristics and Potential of Plastic Recovery at Bakri Landfill, Muar, Malaysia

Abstract

The objective of this study was to evaluate the composition and characteristics of the generated municipal solid waste (MSW) in order to obtain information about the quantity of recoverable plastic at Bukit Bakri landfill Muar, Malaysia. Solid waste sampling and laboratory analysis were carried out according to the random sampling method based on American Society of Testing and Materials (ASTM) standards to determine the waste compositions and proximate analysis (moisture content, volatile matter, ash content and fixed carbon). The total quantity of MSW generated at the site was 330 ton/day made up of 25 individual types of waste. The main compositions of the generated waste were 39% food waste, 12% plastic waste and 16% paper which accounted for about 67% by weight. About 12% of disposed materials at Bakri landfill consisted of recoverable plastics of which 9% plastic film, 2% rigid plastic and 1% plastic foam. The average moisture content of the waste was between 50-58%. Although, there is significant volume of recoverable plastic at the disposal site (approximately 35 tons/day), this materials are still being land filled without any form of treatments. Based on the results obtained, this study has recommended the plastic recovery plan as a feasible MSW strategy to reduce the amount of disposed waste at Bakri landfill.

Characterization of chrome buffing dust (CBD) generated from NILEST tannery associated with pathogenic fungi

“…Organic carbon is the carbon remaining on surface as charcoal. The high percentage of the organic carbon in waste materials such as metals (74%) shows that this element requires a longer detention time on the surface of the furnace to achieve complete combustion compared to paper waste, food waste or even textile that has been reported by Kalanatarifard and Go (2012). In this study, the result obtained due to low organic content in chrome buffing dust agreed with the report of Kalanatarifard and Go (2012).…”

“…This represents the natural substances after carbon, oxygen, sulfur and water. Kalanatarifard and Go (2012) recorded high percentage of ash content in fruit husk, rubber and leather with 27 and 22%, res-pectively, dominating in the ash content percentage. In this current investigation, low or moderate percentage of ash content is an evident that favoured the activity fungi in solution or medium.…”

End- of- Life Scenarios for Municipal Solid Waste of Defence Housing Authority Lahore, Pakistan

“…Organic waste is feedstock for anaerobic digestion in S3. As a result of this process not only fuel gas is produced, but also soil fertilizer in the form of compost [26]. This process on the whole generates some benefits and some burdens to the environment.…”

Composition of Solid Waste in Al Jabal Al Akhdar, a Mountain Region Undergoing Rapid Urbanization in Northern Oman

“…It is useful therefore to make a comparison between this study and other studies from both developing and developed countries. Studies in San Quintin and Vicente Guerrero, northern Mexico [24], Darjeeling, India [4] and Muar, Malaysia [25], representing rural regions and developing countries, showed similarities to Al Jabal Al Akhdar in that food is one of the major categories in the household and municipal waste along with paper and plastic. In developed countries however, paper and paper board are the dominant waste, followed by food.…”
