  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • Municipal solid waste - waste to energy conversion in India: an overview

    Municipal solid waste (MSW) is generated in enormous quantities, in India, causing environmental problems. It is collected primarily by sweeping in India and dumped on the outskirts of urban areas, which pollute the environment. Such MSWs also release methane and carbon dioxide, which are important greenhouse gases. MSW comprises biodegradable material. The MSW disposal methods in India mainly ...

  • Specific Technologies for Separation of Recyclable Materials From Municipal Solid Waste (MSW), Applicable in Bucharest - Romania

    Urban waste usually comes from household and public activities that mean private lodgings, shops, hotels, restaurants, offices, etc. Taking into consideration the year 2000 as a standard level, we estimate about 11,200 t/day of urban waste to be produced in Romania, from which about 2,200 t/day only in ...


  • Extraction of fuel from municipality solid wastes using an updraft gasifier

    In Bangladesh, cities are confronted with the problem of how to dispose large quantities of municipal solid waste (MSW). Gasification is a process that uses heat, pressure and steam to convert materials (MSW) directly into a gas composed primarily of carbon monoxide and hydrogen. The main objectives of this paper are: 1) to study gasification processes; 2) to design, fabrication and performance ...

  • New guidelines for characterization of municipal solid waste: the Portuguese case

    This report proposes a new set of guidelines for the characterization of municipal solid waste. It is based on an analysis of reference methodologies, used internationally, and a case study of Valorsul (a company that handles recovery and treatment of solid waste in the North Lisbon Metropolitan Area). In particular, the suggested guidelines present a new definition of the waste to be analysed, ...

  • Mesophilic and thermophilic anaerobic digestion of source-sorted municipal solid waste

    A change in existing collection systems for household waste is presently in progress in many Swedish municipalities. The objective is to separate the decomposable fraction from non-biodegradable waste in order to facilitate biological treatment and recycling of nutrients. The main reason for this development is the effort to replace landfilling of nutrient-rich, wet organic waste with sustainable ...

  • Anaerobic fermentation of organic solid wastes: volatile fatty acid production and separation

    Anaerobic fermentation of organic municipal solid waste was investigated using a leach-bed reactor (LBR) to assess the volatile fatty acid (VFA) production efficiency. The leachate recycle rate in the LBR affected the VFA composition of the leachate. A six-fold increase in the recycle rate resulted in an increase of the acetic acid fraction of leachate from 24.7 to 43.0%. The separation ...

  • Effect of co-managing organic waste using municipal wastewater and solid waste treatment systems in megacities

    A model was developed to calculate the mass and heat balances of wastewater and municipal solid waste treatment plants when these plants operate either separately or together with a mutual dependence on mass and energy. Then the energy consumption, life cycle costs (LCCs), greenhouse gas (GHG) emissions and effluent quality were evaluated under various scenarios to identify the most effective ...

  • Sorting and Recycling Municipal Solid Waste (MSW) in Xiamen City, China - Case Study

    TOMRA Sorting Recycling is playing a pivotal role in the implementation of automatic sorting at the MSW plant in Xiamen Background The city of Xiamen, renowned for its natural beauty, is located on China's southeast coast, in Fujian Province. Its famous seascape and clean natural environment are a magnet for tourists, and the city government wants to keep things ...

  • Economic Analysis of Options for Managing Biodegradable Municipal Waste

    The main objective of the study was: To conduct an economic evaluation, that considers both private and social welfare costs and benefits, of existing options for managing the biodegradable fraction of municipal solid waste. Although all management options (anaerobic digestion, composting, landfilling, incineration, etc.) receive some consideration in the study, the main emphasis has been on the ...


  • Application of LCA to support solid waste management policy in Phuket

    Life Cycle Assessment (LCA) is employed to evaluate the environmental performance of the existing Municipal Solid Waste (MSW) management system in Phuket and compared with different possible alternative Integrated Waste Management Systems (IWMSs). The results show that the scenario comprising source separation of waste for anaerobic digestion and recycling plus incineration (with energy recovery) ...

  • Solid Waste Management: A Case Study of National Refinery Limited

    Investigations have been carried out to assess and characterize the waste being generated in one of the largest petrochemical refinery of Pakistan. It was found that the refinery complex generates about 2000 metric tons of solid waste and about 0.55 million gallons of waste water per day. Besides these gaseous pollutants like H2S, CO, CO2 NO2, and particulate matter are also emitted in the ...


  • Evaluating Citizen Attitudes and Participation in Solid Waste Management in Tehran, Iran

    Recently, increasing attention has been paid to the environmental impact of solid waste in Iran. Consequently, solid waste management has become a remarkably important issue. Solid waste comprises a wide range of materials and comes from a variety of sources. Having a population of about 10 million (about 1/7 of Iran’s total population), Tehran is among the most populated capitals in the world. ...

  • Environmental efficiency of composting versus anaerobic digestion of separately collected, organic waste

    Environmental policy in the Netherlands among others aims at closing material cycles and minimising the amount of waste requiring final disposal. In this policy the highest priority is given to the prevention of waste production followed by (in descending order of preference) reuse, incineration with energy recovery and sanitary landfilling. In the implementation of this solid waste policy also ...

  • National Separation Strategy for MSW in Finland

    Abstract A spreadsheet model, TASAR, was developed for analysing national separation strategies of municipal solid waste (MSW) in Finland. The model was used to answer the following question: What kind of a strategy is needed to attain the recovery rate target of 70 %wt set for MSW in Finland? TASAR proved to be a useful planning tool. Firstly, source separation was studied resulting in ...


  • Source Separated MSW Composting in the US

    MUNICIPAL solid waste composting projects are being launched based on residential separation of the compostable stream from recyclables and trash - quite widespread in Europe and increasingly in Canada. One trend - typically in cities and suburban communities - is to add source separated residential organics to existing yard trimmings collection programs. Composting facilities permitted to ...

  • Source separated residential composting in the US

    THE Field of Dreams movie theme, “if you build it they will come,” is definitely à propos to source separated residential organics composting. While conducting this year's survey, we asked program managers what they think the key ingredients are to offering households the ability to divert more than just yard trimmings at the curb - a practice that is widely adopted in some Canadian provinces and ...
