“…The main purpose to manage MSW efficiently include reducing (i) the amount of MSW generated, (ii) the impact on the environment with a lower cost of disposal of MSW, and (iii) the impact on human health [14]. In MSW management in developing countries, five typical problems can be identified: (i) inadequate service coverage, (ii) operational inefficiency of services, (iii) limited utilization of recycling activities, (iv) poor management of non-industrial hazardous waste, and (v) shortage of landfill disposal sites [15].…”

The generation of municipal solid waste (MSW) is increasing globally every year, including in Malaysia. Approaching the year 2020, Malaysia still has MSW disposal issues since most waste goes to landfills rather than being utilized as energy. Process network synthesis (PNS) is a tool to optimize the conversion technologies of MSW. This study optimizes MSW conversion technologies using a PNS tool, the "process graph" (P-graph). The four highest compositions (i.e., food waste, agriculture waste, paper, and plastics) of MSW generated in Malaysia were optimized using a P-graph. Two types of conversion technologies were considered, biological conversion (anaerobic digestion) and thermal conversion (pyrolysis and incinerator), since limited data were available for use as optimization input. All these conversion technologies were compared with the standard method used: landfilling. One hundred feasible structure were generated using a P-graph. Two feasible structures were selected from nine, based on the maximum economic performance and minimal environmental impact. Feasible structure 9 was appointed as the design with the maximum economic performance (MYR 6.65 billion per annum) and feasible structure 7 as the design with the minimal environmental impact (89,600 m 3 /year of greenhouse gas emission).

“…Rapid population growth and urbanization have generated a large amount of municipal solid waste (MSW) nowadays. The generation of municipal solid waste (MSW) has increased by 95 percent over the past 10 years due to the rapid development in the urban area [1]. Solid waste covers all domestic wastes and non-hazardous waste such as commercial and institutional discharge, waste from roads and waste from construction activities.…”

Today, the increasing of solid waste generation became the major issue in Malaysia due to high population growth. The greenhouse emission and high energy consumption resulted from improper management of solid waste have caused a significant effect on the inhabitants and the environment. Hence, it is necessary to develop an integrated solid waste management plan to combat this problem. The challenges are to educate the communities in managing their own waste in a good manner. Recycling awareness among society should also be emphasized to ensure that waste generated can be properly managed. This paper focused on the greenhouse gases (GHG) emissions and energy consumption of municipal solid waste management. The aim of this research is to estimate the income generated from recycling activities from the municipal authority in Shah Alam and Klang district in Selangor. The analysis was done using waste reduction model (WARM) created by the Environmental Protection Agency (EPA), United States. The results indicated that the GHG emission that can be reduced by the Klang authority was 3,024.20 metric tons of carbon dioxide equivalents (MTCO2E) compared to 2,577.80 MTCO2E for Shah Alam authority. The same result has been obtained for the energy emission which indicated the highest saving was 824.90 metric tons of coal equivalents (MTCE) by the Klang authority. However, the Shah Alam authority can only save the amount of 702.80 MTCE. The total incremental of energy used generated by WARM showed that Klang authority can save 23,290.20 million British thermal unit (MBTU) compared to Shah Alam authority of 19,862.80 MBTU. The percentage difference between the Klang authority and the Shah Alam authority in the GHG and energy emission reduction was approximately 14.80%. The total income from recyclable materials for Klang and Shah Alam authority was obtained as RM 918, 638.16. The estimation of GHG emission from both Klang and Shah Alam authority was depending on the solid waste generated and disposal method. In terms of GHG emission, waste separation includes recycling activities could reduce the GHG emission, less air pollution and more environmentally friendly.

“…Consequently, such uncollected waste often get mixed with human and animal excreta and indiscriminately dumped into the streets and drainage flow which contributes in flashfloods along with acting as breeding house of insects and rodent vectors (USEPA, 1995). Herein, SWM encompasses all aspects concerned with generation, on-site handling and storage, collection, transportation, reuse, recycling, and final disposal; therefore, it is considered as multi-disciplinary approach based on engineering principles (Samsudin and Don, 2013). Due to the dearth of financial resources, institutional weakness, and improper choice of technology SWM services is still far from satisfactory level in Bangladesh.…”

Status of Household Solid Waste and People’s Perception on its Management at Sitakunda Upazila, Chittagong

Urban household solid waste (HSW) is well-known, but has little knowledge about the rural areas and sub-cities. The quest of the study was to investigate current HSW management system and people's attitude towards it's at Sitakunda Upazila. The study was conducted through a semi-structured questionnaire survey by interviewing 150 households from 3 different socioeconomic groups. The results showed that on an average each household generated 1.26 kg/day wastes which stands at 0.24 kg/person/day in the study area. However, HSW generation is positively correlated with family size (r xy =0.991, p˂0.05), average age of family members (r xy =0.455, p˂0.01), and monthly earnings (r xy =0.999, p˂0.01) of the households. Amidst the various categories of wastes, vegetable and food wastes (VFWs) were identified as the highest value 68.4%. In contrast, 24.6% of the generated wastes were recyclable and 75.4% non-recyclable; 82.1% organic and 17.9% inorganic. A large percentage of sampled households opined that present HSW management involves merely partial collection that is also irregular in urban areas but absent in rural areas. Unfair HSW collection was noticed by 58.7% and partial source segregation is also rare 14%. Besides, 42.7% people were found to dispose their daily generated wastes by open dumping and 25.3% nearby lagoon. A large number of people were dissatisfied 68% and only 6.7% were satisfied with the existing HSW management system. In addition, most of the people encountered bad odor problems by 28.7% and wastes spread on roadside by 38%. Significant quantity of recyclable wastes was noticed to collect from households by hawkers/scraps in the study area and very few household were found to use VFWs with cow-dung to generate biogas.
