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.

Using gray relational analysis, the relational degree between the production and impact factors of municipal solid waste (MSW) is calculated. Based on gray model GM(1,5) and gray model GM(1,1), the prediction models of MSW production were set up, on which base, MSW production from 2010 to 2020 in Changchun city is predicted. The result shows the waste production prediction models on gray theory have minimal residuals, higher precision and a relatively high relational degree, and by 2020, MSW production in Changchun City will reach 228.67×104 t by estimation.

Abstract Accurate prediction of Municipal Solid Waste electricity generation is very important for the fine management of cities. In this study, Shanghai was taken as the research object, and six influencing factors of Municipal Solid Waste production were used as input indexes to realize the effective prediction of Municipal Solid Waste production through constructing a neural network model based on bidirectional long short term memory. At the same time, based on the predicted results and the forecast formula of MSW electricity generation, this study realized the harmless treatment of Municipal Solid Waste in Shanghai. Firstly, the economic, demographic, and social indicators related to Municipal Solid Waste were determined. Secondly, the bidirectional long and short time memory model is used to learn the features of the input indexes. Finally, the electricity generation capacity of Shanghai municipal solid waste in the next six years is predicted with the municipal solid waste electricity generation formula. The experimental results show that, firstly, the MAPE value of the bidirectional long and short time memory combination model established in this paper is 7.390, and the prediction performance of this model is better than that of the other five structural methods. Second, it is predicted that in 2025, the maximum electricity generation of Shanghai Municipal Solid Waste under the three scenarios will be 512752MkW, and the minimum electricity generation of Shanghai Municipal Solid Waste will be 260668MkW. Finally, this paper can be used as a scientific information source for environmental sustainability decision-making of domestic Municipal Solid Waste electricity generation technology.

Waste Production

The European Commission has adopted a very ambitious circular economy package and has consequently revised many legislative proposals on waste. The new targets include achieving a recycling rate of 65% by 2030 and imposing a cap on landfilled waste to no more than 10% (as a percentage of weight). Using available European and national databases on municipal solid waste indicators, we have analysed municipal solid waste production trends for Croatia and have benchmarked the indicators against other EU member states and EU averages. Our analysis points out that the production of municipal solid waste has steadily risen over the last two decades. Although Croatia produces a relatively low amount of municipal solid waste compared with other EU countries and EU averages, gross domestic product adjusted waste production reveals that for every euro of gross domestic product Croatia produces substantial amounts of municipal solid waste. As a matter of fact, among all the EU member states, only Bulgaria had a worse performance than Croatia. Regarding recycling rates, Croatia recycles 15% of its municipal solid waste and incinerates approximately 3% (by weight). The rest (82% by weight) is currently being landfilled. Regarding the treatment of waste, Croatia has implemented mechanical–biological treatment technology, but our analysis reveals that the initial number of mechanical–biological treatment plants will likely have to be scaled down taking into consideration the new EU waste management targets.

Starting Point

<p>Municipal Solid Waste (MSW) management activities are an important tasks of both national and municipal governments as they can induce significant impacts on the environment, the economy and the living quality of the population involved.</p><p>The optimal design of a MSW management plan depends greatly on the waste production values and its distribution over the territory. This production depends mainly on the socioeconomic level of its inhabitants. On the scientific literature several studies have already been carried out, concluding that there exist a direct relationship between the waste production of a certain country or region and its Gross Domestic Product (GDP). Therefore, if GDP increases, so will the rate of waste production, although not necessarily at the same rate.</p><p>The objective of the work was to carry out an evaluation of the future production of (MSW) within the V5 production area inside Valencia Region (Spain) in the 2012-2034 time horizon. The year 2011 was used as the starting point for the simulation as this was the last year in which the population census was taken. The correlation between the evolution of the economic growth indicators and the waste production indicators was analyzed. Results showed a linear correlation between all the variables studied so that variations in one of them are reflected in the same direction in the others.</p>
