St. Petersburg, as the second most important Russian city in Russia is facing with waste related problems which requires taking immediate actions. The excessive diurnal volume of municipal waste generation and insufficient waste management system ring the bells to warn the decision makers. Focusing on problems, insufficiencies and opportunities of the waste management system, the paper goes through the evaluation of details of the dominant situation in St. Petersburg and two models are introduced to improve the system. At the end, an estimation of biofuel, heat and electricity generation will be provided for four incineration facility installments with design capacity of each 315,000 tons of waste per day. It will be shown that the contributing share of bioconversion processes is significant and an acceptable portion of 8% of annual electricity consumption can be supplied via those processes as well as production of 477 million liters of ethanol.

An efficient and effective waste management system is one of the key issues for urban areas. Such a waste management system should be effective and economically viable with minimal environmental impact. The Life Cycle Assessment (LCA) methodology is an effective tool for identifying and assessing environmental impacts, it also enables comparing alternative waste management options. The aim of this study is to identify and assess the environmental impacts caused by the waste management system of mixed municipal waste for the city of Krakow for the year 2017. Three scenarios are evaluated for mixed waste: 1) incineration in a new waste-to-energy plant, 2) mechanical-biological treatment (MBT), ballast and stabilized waste is landfilled, refuse derived fuel (RDF) is produced but not incinerated, 3) treatment in the MBT plant, with incineration of RDF in the waste-to-energy plant. The results of modelling show that all scenarios exert a negative impact on the environment in some impact categories, while in other categories - a positive impact. Taking into account the values in all impact categories, the scenario with the lowest overall environmental impact is MBT with incineration.

Abstract Increasing the amount of waste generation is a problem in every city. This research aims to know the waste transportation and management system to analyze its compliance with the applicable national and local regulations in Indonesia. Demak Regency produced 208 kg/day of waste which this number represent 35.18% of waste generated in Demak Regency from domestic and non domestic sector. The waste is transported and not sorted at sources, as the same with many other cities in Indonesia. Therefore, a proper waste management system is needed for Demak Regency that includes five aspects, which include technical, institutional, financial, regulation, and community aspects. The Environmental Agency of Demak Regency is the institution in charge of waste management in Demak Regency. The analysis shows that improvements are needed to achieve appropriate waste management system in Demak Regency. Therefore, efforts should be made to improve waste management in the Regency, for example, by improving technical performance, human resources, and promoting community-based waste management in the studied area.

"The reality remains uncomfortable, the climate crisis is coming with extreme phenomena more and more devastating around the globe and more and more people and more and more parts of ecosystems are suffering from the greed of large companies and lack of constructive action and coherent decision-makers. There are various types of waste generated during operation, and to be able to implement a waste management system, it is necessary to identify and quantify the different types of waste on board. The purpose of this paper is to examine the responsibilities, management, handling and disposal of ship-generated waste and the requirements for the preparation of an on-board waste management plan.

This article outlines the problem of waste accumulation as well as the associated environmental consequences in Ukraine due to the disparities between waste generation and utilization capacities. The analysis of quantitative parameters of waste generation sources and the territorial structure of Ukraine’s utilization capacities was carried out, and the spatial assessment of waste management system balance within regions was made. The work also identifies stages of territorially balanced management systems formation within the scope of current recycling technologies in the regional dimension. Methodological approaches to researching the balance conditions of waste management systems at the regional level are substantiated, which presupposes a mathematical model of these processes through the development of a system of equations, which depending on the tasks determine either the timing of the outlined phases of solving waste management issues based on available investment resources, or the amount of funds required to ensure proper timing of the innovative disposal facilities commissioning.

The municipal waste management system of the region of Irkutsk is described and a life cycle assessment (LCA) performed to assess the environmental performance of the system. Annually about 500 000 tons of waste are managed. The waste originates from three sources: household waste (27%), commercial waste (23%) and office & institutional waste (44%). Other waste of unknown composition constitutes 6%. Only 3% of the waste is recycled; 97% of the municipal waste is disposed of at the old Alexandrovsky landfill. The environmental impact from the current system is dominated by the landfill, which has no gas or leachate collection system. The global warming contribution is due to the emission of methane of the order of 420 000 tons CO2-equivalents per year. Collection and transport of the waste are insignificant compared with impacts from the landfill. As the old landfill runs out of capacity in a few years, the LCA modelling showed that introduction of a new and modern landfill with gas and leachate collection could improve the performance of the waste management system significantly. Collection of landfill gas and utilization for 30 years for electricity production (gas turbine) would reduce the global warming completely and result in a net saving of 100 000 CO2-equivalents per year due to storage of biogenic carbon in the landfill beyond 100 years. Considering other first-order degradation rates for the landfilled organic matter did not overtly affect the results, while assumptions about the top cover oxidation of methane significantly affected the results. This shows the importance of controlling the gas escape from the landfill.
