There is a general phenomenon of incoordination between garbage classification management and participation behavior, which seriously affects the sustainable management efficiency of domestic garbage. In order to solve this problem, this paper introduced the subject-object-process model into the waste classification management system, and constructed a mandatory classification management model of municipal solid waste and a comprehensive evaluation index system. Taking Beijing, China, as an example, the coupling coordination degree of garbage classification behaviors of residents in different was compared, and the coordination status of household waste management and behaviors was obtained. The results show that the synergy between government management and residents’ household waste classification behavior is between 0.40 and 0.68, and the synergy between enterprises’ participation in governance and residents’ behavior is between 0.45 and 0.75. The coordination degree between domestic waste management and residents’ participation behavior is generally in primary coordination or slight imbalance. The synergy degree between the secondary indicators of domestic waste management and residents’ behavior is higher than that of the tertiary indicators. Superposition effect of integrated management measures is better; among the psychological factors affecting residents’ classification behavior, the awareness rate and recognition degree of waste classification are very high, the awareness of environmental responsibility and social pressure are lagging behind. The study of synergy under the framework of subject-object-process not only quantifies the overall synergy between management and residents’ behavior, but also provides a method to further implement garbage classification management in a targeted manner. Based on the synergy analysis, according to the weak links of various regions, classified management is carried out around publicity and education, supervision and management, assessment, rewards and punishments.

One of the bigest problems cities in Indonesia such as Jakarta is still cannot be solve properly the problem of urban waste. The amount of municipal solid waste of DKI Jakarta based on data from the Ministry of Environment and Forestry in the 2017-2018 period is 6234.44 tons / day with 1.85 tons / day sourced from the city of East Jakarta. East Jakarta with its main market namely Kramat Jati market has a fairly complicated municipal waste problem, this has an impact on the amount of waste around the wholesale market, one of which is the village of Kampung Tengah. Kampung Tengah has a quite serious waste problem because the waste is not only produced from household waste, but from onion peeler craftsmen who later the onions are sold to the Kramat Jati market. To overcome these problems, one of the solution is by empowering the community in managing household waste. Therefor, Kampung Tengah communities are given knowledge about waste management through training. The training conducted is about how to use methods that are easy to apply and effective in reducing the amount of waste generation, namely the Takakura method. Participants given the training were focused on RW.10 with 25 participants. The result of the training is that the community has been able to apply the Takakura method to make compost from household waste.

Abstract Production of refuse derived fuel from municipal solid waste in future shall play a strategic role in an integrated waste management system. The amount of landfilled biodegradable materials thus will be diminished according to provisions of the 1999 Waste Landfill Directive. The aim of this article is to evaluate cost effectiveness based on cost evaluation of the different complication of the waste pre-treatment equipment complectation and based on regenerable waste quantities in Latvia. The comparison of cost estimates is done in 3 scenarios considering potential waste quantities in Latvia: Scenario I - planned annual waste quantity is 20 kT; Scenario II - 40 kT and Scenario III - 160 kT. An increase in amount of waste and processing capacity means the decrease in costs of mechanical pre-treatment of 1 ton of waste. Thus, costs of mechanical sorting line under different scenarios with capacities of 10 t h-1, 20 t h-1 and 80 t h-1 are EUR 32 per t, EUR 24 per t and EUR 15 per t, respectively. Most feasible cost for a set of mechanical pre-treatment equipment for the capacity of 10 t h-1 is EUR 32 per t by using rotating drum screener with the following manual sorting. Mechanical pre-treatment equipment of unsorted municipal waste is economically nonbeneficial, when the use of fine (biologically degradable) fraction is not possible. As the sorting of biodegradable kitchen waste is not developed under the current waste management system in Latvia, the lines for mechanical pre-treatment of household waste would be better to install in landfills.

AbstractMany cities in developing countries lack adequate drainage and waste management infrastructure. Consequently, city residents face economic and health impacts from flooding and waterlogging, which are aggravated by solid waste infiltrating and blocking drains. City governments have recourse to two strategies to address these problems: a) ‘hard’ infrastructure-related interventions through investment in the expansion of drainage and waste transportation networks; and/or, b) ‘soft’, low-cost behavioural interventions that encourage city residents to change waste disposal practices. This research examines whether behavioural interventions, such as information and awareness raising alongside provision of inexpensive street waste bins, can improve waste management in the city. We undertook a cluster randomized controlled trial study in Bharatpur, Nepal, where one group of households was treated with a soft, low-cost intervention (information and street waste bins) while the control group of households did not receive the intervention. We econometrically compared baseline indicators – perceived neighbourhood cleanliness, household waste disposal methods, and at-source waste segregation – from a pre-intervention survey with data from two rounds of post-intervention surveys. Results from analysing household panel data indicate that the intervention increased neighbourhood cleanliness and motivated the treated households to dispose their waste properly through waste collectors. The intervention, however, did not increase household waste segregation at source, which is possibly because of municipal waste collectors mixing segregated and non-segregated waste during collection. At-source segregation, a pre-requisite for efficiently managing municipal solid waste, may improve if municipalities arrange to collect and manage degradable and non-degradable waste separately.

Level Of Significance

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 need for resilience and an agile waste management system in Saudi Arabia is vital to control safely the rapid growth of its municipal solid waste (MSW) with minimal environment toll. Similarly, the domestic energy production in Saudi Arabia is thriving and putting a tremendous pressure on its huge reserves of fossil oil. Waste to energy (WTE) plants provides a golden opportunity for Saudi Arabia; however, both challenges (MSW mitigation and energy production) are usually looked at in isolation. This paper at first explores the potential of expanding the WTE energy production in the eastern province in Saudi Arabia under two scenarios (complete mass burn with and without recycling). Secondly, this study analyzes the effect of 3Rs (reduce, reuse, recycle) practices implementation in a residential camp (11,000 population) to influence the behavior of the camp’s citizens to reduce their average waste (kg/capita). The results of the 3R-WTE framework show a potential may reach 254 Megawatt (MW) of electricity by year 2030. The 3R system implementation in the camp reduced MSW production from 5,625 tons to 3000 tons of household waste every year, which is considered lower than what the surrounding communities to be produced in the same area.

The results of experimental studies of humidity, ash content, calorific value for сomponents of municipal solid waste in Cherkassy city are presented. The results of the research are used to develop an integrated waste management and recycling system in the Cherkassy city.  The waste management strategy has been adopted in Ukraine. It determines the main directions of reforming the system of sanitary cleaning of cities in order to minimize environmental pollution in accordance with EU standards. In the process of preparation of the regional implementation plan for the Strategy in Cherkassy, a study of the morphology, energy and environmental characteristics of the components of solid domestic waste (SDW) was made. This article presents the results of experimental studies of humidity, calorific value and ash content for 8 components of waste: paper, cardboard, composite materials, textiles, hygiene products, plastic, other combustible materials, wood shavings are presented. Humidity is also determined in organic residues and in fine fractions. The investigations were carried out at the experimental stand of the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine. Due to the absence in Ukraine of standards for the study of energy characteristics of solid waste, the measurements were carried out in accordance with standards for solid organic fuels, which slightly differ from the EU methods for the study of solid waste. In order to develop regional integrated waste management plans within the framework of the strategy implementation, based on the qualitative analysis of MSW components, it is necessary to develop standards for determining the energy characteristics of SDW in line with European normative documents. The study of the energy characteristics of solid waste showed a significant heterogeneity in the components of solid waste, which significantly complicated the determination of characteristics and led to a considerable scatter of results and an increase in measurement uncertainty. This happened due to low weight and the need for thorough homogenization of the sample, which was experimentally investigated in accordance with the method of preparation of an analytical sample. The article analyzes need for adaptation of the European methods of detailed morphology of solid domestic waste in Ukraine, which is necessary for separate waste collection. The results of the research are used to develop an integrated waste management and recycling system in the city of Cherkassy.

Households’ contribution in solid waste classification and recycling of municipal household solid waste is one of the essential factors influencing municipal solid waste management. We identify and investigate the factors influencing solid waste management classification as well as mechanism used by households to dispose waste in their communities. Based on the survey data of households in Hangzhou China in three different communities, factors that affect household disposal and their degree of influence have been analyzed, followed by discussion on decision-making mechanisms. The results show that household behavioral selection has been linked to several key factors which are Environmental attitude, knowledge and education, classification facilities and services, and policies. The research has also determined to reveal the response of the people to solid waste classification, and the combined effect of the factors is almost twice that of the former. In addition, environmentally friendly facilities and programs are most successful in encouraging the involvement of household in identification and recycling. Finally, the research put forward applicable policy suggestions for the comprehensive management of municipal Household Solid Waste classification and recycling.

The ineffective management of household solid waste (HSW) in most developing cities in Africa including Monrovia has become a major issue threatening the environment and public health. In response to these waste challenges, developed countries have embarked upon major environmental reforms, and have made advances in best practices and sustainable management of their Municipal Solid Waste (MSW). However, in most developing countries like Liberia, such environmental reforms have not been initiated and therefore the situation has become compounded; this is due to several factors impeding the development of a sustainable municipal solid waste system. This study, therefore, aims to critically analyze the influencing factors of solid waste management; the characteristics of household waste and suggest management solutions for effective and sustainable management.<br/> Results from the analysis of data, using The Ordinary Least Square Regression (OLS) method estimates the average household waste per capita generation as 0.76kg/capita/day. Regarding the composition of the waste stream, the results show that 67% of the waste sampled from Monrovia is biodegradable and mostly comprised of high wet weight and high moisture content kitchen waste. On the other hand, the remaining percentage is mostly non-degradable but recyclable materials such as glass ceramics and metals. This suggests that due to the high moisture content in the waste, samples are suitable for composting and other mechanical and biological management options. Using the stratified sampling method, 300 households were chosen. Multiple regressions were conducted to determine the relationship between waste generation and socio-economic factors and these showed that the effect of income, household size and the environmental concern on HSW generation is statistically significant at a 1% significance. However, further findings revealed a negative relationship between income and HSW generation at a 1% level of significance. These findings provide new insight regarding the role of socio-economic characteristics affecting the generation of household waste in Monrovia.
