This study is aimed at estimating economic value of municipal solid waste (MSW) reduction program in the Mekong Delta by employing the willingness-to-accept (WTA) approach. This research will address two important issues in current growing literature about MSW management. First, this is the first research to evaluate economic value of the MSW reduction program in Mekong Delta. The second major contribution is the approach employed - supply curve through the WTA. This program requires community participation and provision incentives to them, therefore the requirement of public acceptance through WTA is estimated. Findings reveal that people are willing to accept an average of 30,000 VND/month for the MSW reduction program. Assume that household's MSW management fee subsidy policy is canceled, and the household is facing a full fee for the MSW collection (about 150,000 VND/month), they are willing to classify MSW at source to get a reduction of 30,000 VND or they are willing to accept a fee of 120,000 VND/month. In addition, it is interesting that more than 70 percent of people are willing to participate in this program. The determinants of WTA identified include the type of MSW at the source, education level, type of urban areas. This research then proposes that MSW management implementation policy should be focused on motivating households and improving people's perception of MSW. In case of government budget deficit, community participation would be more appropriate to manage MSW.

Peningkatan jumlah penduduk dan pertumbuhan pesat proses perbandaran dan faktor lain secara langsung mengakibatkan penghasilan sisa pepejal perbandaran. Jumlah kuantiti besar yang dihasilkan terutamanya di Semenanjung Malaysia merekodkan peningkatan daripada 16,200 tan sehari pada tahun 2001 kepada 19,100 tan sehari pada tahun 2005 atau purata per kapita sebanyak 0.8 kg sehari. Jumlah ini kian meningkat dari tahun ke tahun selari dengan penghasilan sisa pepejal di kawasan perbandaran negara–negara Asia lain yang dianggarkan berjumlah 8 juta tan sehari. Justeru, kertas kerja ini membincangkan secara ringkas senario penghasilan sisa pepejal perbandaran di Malaysia. Perbincangan terfokus kepada aliran penghasilan sisa pepejal perbandaran, jenis komposisi, faktorfaktor penyumbang, selain masalah pengurusan sisa pepejal yang sedang dialami oleh Malaysia. Juga dibincangkan, data statistik terkini yang ada hubungkait dengan pengurusan sisa pepejal perbandaran untuk mengetahui keadaan serta rancangan yang sedang dan akan dilaksanakan oleh kerajaan. Perkembangan terkini menunjukkan kerajaan Malaysia sedang dan akan membuat tindakan kehadapan untuk menangani masalah pengurusan sisa pepejal perbandaran di seluruh Majlis Perbandaran (termasuk dewan bandaraya) di seluruh negara. Antara langkah yang diambil termasuklah menutup operasi beberapa tapak pembuangan terbuka terpilih, menaikkan taraf beberapa tapak pengambusan sedia ada kepada pengambusan jenis sanitari, membina pusat–pusat pemindahan, serta memberi keutamaan sistem pelupusan alternatif di masa terdekat. Selain itu, penubuhan perbadanan pengurusan sisa pepejal negara serta meluluskan pembentukan undang–undang khusus berkaitan pembersihan dan pengurusan sisa pepejal perbandaran pada November 2007 lalu dilihat sebagai langkah proaktif ke arah mencapai sasaran pengurusan sisa pepejal yang mampan untuk penyelesaian jangka masa panjang. Kata kunci: Malaysia; pelupusan; pengurusan sisa pepejal; perbandaran; sisa pepejal perbandaran Increasing population and tremendous urbanisation growth and other factors influence directly the municipal solid waste (MSW) generation in Malaysia. The huge quantity of MSW generation, particularly in Peninsular Malaysia, has increased from 16,200 tonnes per day in 2001 to 19,100 tonnes per day in 2005 or an average of 0.8 kg/capita/day. The amount increases yearly and seems to grow in parallel with the urban areas in many Asian countries which are estimated to produce approximately 8 million tonnes per day. Thus, this paper briefly discusses the scenario of MSW generation in Malaysia. It focuses on the trends of MSW generation, the composition of MSW, the contributing factors as well as the management problems occurring in Malaysia presently. In addition, some updated statistical figures related to the MSW and management aspects are provided to clarify the present situation and the government’s future planning. Recent development indicates that the Malaysian government has taken forward to deal with such problems in MSW management across the municipalities through closed dumping sites, upgrading existing conventional landfills to sanitary status, constructing new transfer stations and giving serious priority for an alternative disposal system in the near future. Moreover, the establishing a new national solid waste and public cleansing management corporation and enacted a new specific regulations for solid waste and public cleansing management which approved on September 2007 is also seen as a proactive step towards achieving the sustainability of MSW management as a long term solution.

Mumbai, the largest metropolitan city in India, generated 6,256 tons of waste per day in 2001. It is the responsibility of the Municipal Corporation of Greater Mumbai (MCGM) to provide Municipal Solid Waste (MSW) management services; however, the MCGM is not able to handle the increasing quantity of waste. As a result, waste litters all over the place giving rise to health and environmental problems. Hence, there is a need to involve private sector and community participation in waste management. In this paper, a linear programming model is developed to integrate different options and stakeholders involved in MSW management in Mumbai. Various economic and environmental costs associated with MSW management are taken into consideration while developing the model.

Because the consumption of materials is generally higher than their recovery rate, improving municipal solid waste (MSW) management is fundamental for increasing the efficiency of natural resource use and consumption in urban areas. More broadly, the characteristics of a MSW management system influence the end-of-life (EOL) impacts of goods consumed by households. We aim to indicate the extent to which greenhouse gas emissions from a MSW management system can be reduced by increasing waste paper recycling. We also address the stakeholders’ contribution for driving transition towards an improved scenario. Life cycle assessment (LCA) addresses the EOL impacts of the paper industry, driven by the characteristics of MSW management in Florianópolis, Brazil, by varying the level of stakeholders’ commitment through different recycling scenarios. The results show that 41% of the climate change impacts from waste paper management could be reduced when increasing the waste paper recycling rates and reducing waste paper landfilling. To achieve such emissions reduction, the industry contribution to the MSW management system would have to increase from 17% in the business-as-usual scenario to 74% in the target scenario. We were able to measure the differences in stakeholders’ contribution by modelling the MSW management system processes that are under the industry’s responsibility separately from the processes that are under the government’s responsibility, based on the Brazilian legal framework. The conclusions indicate that LCA can be used to support policy directions on reducing the impacts of MSW management by increasing resource recovery towards a circular economy.

Municipal solid waste (MSW) management presents an important challenge for all countries. In order to exploit them as a source of energy, a knowledge of their calorific value is essential. In fact, it can be experimentally measured by an oxygen bomb calorimeter. This process is, however, expensive. In this light, the purpose of this paper was to develop empirical models for the prediction of MSW higher heating value (HHV) from ultimate analysis. Two methods were used: multiple regression analysis and genetic programming formalism. Both techniques gave good results. Genetic programming, however, provides more accuracy compared to published works in terms of a great correlation coefficient (CC) and a low root mean square error (RMSE).

Accurate prediction of municipal solid waste (MSW) generation is necessary for choosing appropriate waste treatment methods and for planning the distribution of disposal facilities. In this study, a hybrid model was established to forecast MSW generation through the combination of the ridge regression and GM(1,N) models. The hybrid model is multivariate and involves total urban population, total retail sales of social consumer goods, per capita consumption expenditure of urban areas, tourism, and college graduation. Compared with the constituent models alone, the hybrid model yields higher accuracy, with a mean absolute percentage error (MAPE) of only 2.59%. Through weight allocation and optimal treatment of residuals, the hybrid model also balances the growth trends of the individual models, making the prediction curve smoother. The model coefficients and correlation analysis show that population, economics, and educational factors are influential for waste generation. MSW output in Hangzhou will gradually increase in the future, and is expected to reach 5.12 million tons in 2021. Results can help decision makers to develop the measures and policies of waste management in the future.

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 (MSW) management is internationally recognized for its potential to be both a source and mitigation technology for greenhouse gas (GHG) emissions. Historically, GHG emission estimates have relied upon quantitative knowledge of various MSW components and their carbon contents, information normally presented in waste characterization studies. Aside from errors associated with such studies, existing data do not reflect changes over time or from location to location and are therefore limited in their utility for estimating GHG emissions and mitigation due to proposed projects. This paper presents an alternative approach to estimate GHG emissions and mitigation using the concept of a carbon balance, where key carbon quantities are determined from operational measurements at modern municipal waste combustors (MWCs).
