Significant Factors

Illegal waste dumping has become a threat to human health and the global environment. In Hong Kong, the government has proposed a quantity-based municipal solid waste charging scheme to reduce waste. However, individuals may still dispose of waste improperly, even if such a scheme has been implemented. In this study, the neutralization theory was adopted and an online survey with 273 respondents was conducted to examine the reasons for improper dumping intentions. A principal component analysis identified two types of neutralization: intrinsic neutralization (including denial of responsibility, denial of injury, and defense of necessity) and extrinsic neutralization (including condemnation of the condemners and appeal to higher loyalties). A regression analysis showed that intrinsic neutralization and gender were significant factors for illegal waste dumping intentions when attitude toward illegal waste dumping was controlled.

Abstract The government has regulated the use of RDF biomass for coal co-firing in power plants. This paper examines biomass (Eichhornia Crassipes and municipal solid waste) characteristics and its potential use as RDF for co-firing in CPP. The method includes the analysis of the composition, supply of raw materials, and biomass characteristics. These results will compare with the coal’s characteristics in CPP. The density of Eichhornia Crassipes in Lake Tondano was 25 kg/m2, with the wet mass of 45,350 tons. The results of the Eichhornia Crassipes sample test for parameters of moisture content, volatile matter, ash content, fix carbon and gross calorific value have a value range of 93%, 5.8-7.1%, 60.21-63.5%, 17.9-22%, 11.4% and 2681-3068 kcal/kg. Amurang CPP uses coal with 4200 kcal/kg calories as much as 1056 tons/day. The co-firing target of 5% requires 52.8 tons of biomass per day. The existing Eichhornia Crassipes biomass in Lake Tondano only supplies the CPP for 62 days. MSW typically has calorific values and moisture with Eichhornia Crassipes biomass, about 3766-4194 kcal/kg and 31.7-87.1%. The use of MSW to cover the lack of Eichhornia Crassipes will ensure the sustainability of the supply of biomass raw materials in the co-firing program at CPP.

This study is proposing a System Dynamics Model for estimating Greenhouse Gas (GHG) emission from treating Municipal Solid Waste (MSW) in South Korea for years 2000 to 2030. The government of country decided to decrease the total GHG emission from waste sector in 2030 as per Business-as-usual level. In context, four scenarios are generated to predict GHG emission from treating the MSW with three processes i.e., landfill, incineration and recycling. For prior step, MSW generation rate is projected for present and future case using population and waste generation per capita data. It is found that population and total MSW are directly correlated. The total population will increase to 56.27 million and total MSW will be 21.59 million tons in 2030. The methods for estimating GHG emission from landfill, incineration and recycling are adopted from IPCC, 2006 guidelines. The study indicates that Scenario 2 is best to adopt for decreasing the total GHG emission in future where recycling waste is increased to 75% and landfill waste is decreased to 7.6%. Lastly, it is concluded that choosing proper method for treating the MSW in country can result into savings of GHG emission.

The Government

The Chinese government is committed to ensuring separation of municipal solid waste (MSW), promoting the integrated development of the MSW management system with the renewable resource recovery system, and achieving construction of ecological civilization. Guided by the methods in Intergovernmental Panel on Climate Change (IPCC) guidelines, the greenhouse gas (GHG) emissions under five waste disposal scenarios in Beijing under the life cycle framework were assessed in this research. The study included collection and transportation, as well as three end disposal methods (sanitary landfill, incineration, and composting), and the emission reduction benefits of electricity generation from incineration and recycling of renewable resources were taken into account. The results show that an emission reduction benefit of 70.82% could be achieved under Scenario 5 in which kitchen waste and recyclables are sorted and recycled and the residue is incinerated, and the selection of the optimal strategy was not affected by changes in the separation rate. In addition, landfill would emit more GHG than incineration and composting. The results of this study are helpful for the government to make a decision on MSW management considering the goal of GHG emission reduction.

Municipal solid waste management is a huge challenge specially in the developing countries. The first and fundamental step to solve the problem of municipal solid waste management is by waste segregation at source and separate collection of waste, which will help to recover recyclable materials and reduce the amount of waste that needs to be disposed at the dumpsite or landfill site. In Nepal, waste segregation at source is mandated by law but the government is not able to implement it successfully. This paper assesses the willingness of the households to practice waste segregation in future if the government enforces the law and various factors that influences the practice. Data was collected from 401 households which was selected using stratified sampling technique from all the municipal wards, the lowest administrative units in Nepal. The finding shows that about 67% of the respondents are willing to segregate waste in future if the government enforces the law. Logit regression model was employed to identify the factors that influence waste segregation practice. The significant variables found from this study are environmental awareness, waste collection service, willingness to pay, make compost, and segregated waste for a week variables, which are statistically significant at 1% level of significance. Income variable is significant at 5% level of significance and gender variable is significant at 10% level of significance. It is recommended that the concerned stakeholders should educate the households on the importance of waste segregation and consider these traits of households before enforcing the law.

The increase of solid waste production is a general problem in municipality, particularly of plastic waste. The durability, light-weight, anticorrosiveness, and inexpensiveness properties of plastic make it favorable to be used in daily life, including in Salatiga. However, plastic is one of some non-biodegradable materials that could lead to soil and water pollution as it contains toxic compounds such as aromatic hydrocarbons, phthalates, and organochlorine. Various studies in municipal solid waste management have been conducted. While those studies often applied various approaches separately, researches in regard to the role of stakeholders in municipal solid waste management are very limited. This study aims to explain the plastic waste management in Salatiga based on the role of the corresponding stakeholders. This qualitative study shows that there are four stakeholders who were involved in municipal plastic waste management in Salatiga. They were the households who generate wastes, the scavengers who sorts the wastes, Bank Sampah and collectors who have the same role in order to collect the wastes and treat the plastic wastes through reusing or recycling processes, and the government. Currently, efforts in waste treatment in Salatiga are focused on the system of collecting-tranferring-disposal mode, waste treatment by reuse and recycle processing, and landfilling. Reducing plastic consumption must take into account the sociocultural aspect and environmental awareness, as the people still interested to use plastic instead of using other materials in substitution. Finally, the role of government is central to educate the community in term of sorting activities and reducing waste production, build the capacity of Bank Sampah, and manage the role of scavengers and collectors. Other alternatives include creating synergy between the collectors and Bank Sampah, as well as ensuring final treatment of the unprocessed wastes disposed by collectors and Bank Sampah.

With the rapid growth of urban economy and population in China, the output of municipal solid waste (MSW) has dramatically increased becoming a constant threat to residents’ living environment and health. The classification intention of residents plays a pivotal role in solving the problem of MSW disposal. While numerous studies have examined the classification behavior of MSW from the perspective of ordinary residents and households, few studies have attempted to understand young people’s sorting intention. The novelty of this research is to explore the determinants that affect young people’s intention toward municipal solid waste sorting (MSWS) by extending the predictive factors of environmental concern and personal moral obligation into the theory of planned behavior (TPB). A sample of 524 young respondents from Hebei Province in China were used to conduct a structural equation model (SEM) validation. The empirical results revealed that, according to the rankings of significance, personal moral obligation, perceived behavioral control, and subjective norm had positive influences on young people’s intention toward MSWS, while attitude and environmental concern did not. Furthermore, the multi-group comparison showed that, compared with the male and rural group, the intention of female and urban respondents to classify MSW was not affected by subjective norms. Some targeted managerial implications were ultimately proposed to promote young people’s intention toward MSWS. This study contributes to the existing knowledge system of MSWS by revealing the classification intention of young people as a group. The findings and implications provide the government with useful insights for encouraging young people to actively participate in MSWS.

A study on the mass flow of municipal solid waste in a mediumsize-city was conducted to analyze the potential waste reduction through the informal sector. The city was opted since the local government targets to improve the informal sector’s role to reduce the waste, which is relatively reasonable to implement the informal sector involvement rather than high technology in waste management requiring high investment, which can be challenging for the local government. Waste Bank and scavengers are informal sectors mainly involved in waste reduction in the area of study. Their capacity to reduce domestic waste was evaluated using a mass balance method. The recovery factor of each waste type was also calculated to determine the average reduction rate. The result showed that scavengers and cleaning staff working in temporary waste disposal sites (TWDSs) could reduce the waste collected daily up to 70%, 61%, 48%, 50%, 3% for paper, plastic, glass, metal, and organic waste respectively. Calculation using mass balance showed that 17 TWDS reduce a total of 8% waste per year, while 13 waste banks reduce 2% waste per year. It indicated that waste reduction in the city was only 10%. The reduction rate is far below the target of the government, which is 20% by 2020. Therefore, the study proposes improving the mass balance by increasing the waste treatment capacity in TWDSs and waste banks. By adding the shredder and composting heaps in some TWDSs and the number of active members in waste banks, the waste reduction may increases from 10% to 24%.

Waste has always been a part of human life settlement and we have been either very careless with our waste by discarding it into the streets, the air, water, and in our backyards, or consciously dumping it close to those least powerful segments of the society at all times. Waste has been a problem for human beings and people have been least concerned about its eco-friendly disposal. Developed countries came up with many programmes, regulations and policies to address the municipal solid waste crisis, but still it is an unresolved problem. Municipal solid waste management is still a complex issue everywhere in the globalized and techno scientific world due to the carefree mindset, rapid urbanization process, unscientific development process and lack of social responsibility. In these circumstances, municipal solid waste managementcannot be addressed by mere technological innovations or adoptions. Moreover, the responsibility of municipal solid waste managementcannot be left to the Government alone. Instead, participation of various stakeholders needs to be ensured and coordinated for achieving sustainability. Taking Thiruvananthapuram Municipal Corporation in the state of Kerala, India as a case, this paper discusses the extent and ways in which various stakeholders engage in the two main approaches for municipal solid waste management, namely- centralized approach and decentralized approach. The research study was conducted during the period June, 2020 to December, 2020.
