Collection and transportation of municipal solid waste (MSW) is a critical factor that governs the overall cost of the MSW management system. With the help of various technological interventions, optimal usage of available resources could bring about a considerable amount of savings. In this study, an attempt has been made to optimize the MSW colle...
Article
Recirculation of leachate in bioreactor landfills accelerates the waste stabilization process. Due to biodegradation-induced changes in waste density, the waste parameters such as hydraulic conductivity and moisture retention characteristics (MRCs) evolve continuously within the landfill. In this study, an approach to evaluate the temporal variatio...
Article
The study aims to investigate the application of anaerobic (AN), aerobic (AER) and semi-aerobic (SA) laboratory scale landfill bioreactors for stabilization of mechanically and biologically treated (MBT) waste of Bangalore city. All major parameters pertaining to the waste, leachate and biogas are continuously monitored during the experiment. Carbo...
Article
Due to the anthropogenic activity, the soil environment is deteriorated by various organic and inorganic contaminants to a greater extent in Bangalore industrial area. The movement of heavy metals in soil is driven by various physical and chemical properties of the soil. This soil contamination leads to groundwater pollution through infiltration. I...
Article
The sustainable landfilling concept has several advantages over conventional waste management practices in addressing various socio-economic and environmental concerns. This study presents an overview of the sustainable landfilling concept and various unit processes associated with it. The waste management approaches followed in the city of Bangalo...

The current practices of containing the waste in dumpsite/landfill are considered as unsustainable due to their negative impact on the environment, society and economy. Remediation of the existing open dumpsite into bioreactor landfills helps in recovering the valuable land area at a faster rate due to the reduction in the time required for waste s...
Chapter
Landfills are one of the major sources of atmospheric methane (CH4), which causes global warming. The microbial oxidation of methane in engineered covers is considered a potent option for the mitigation of methane emissions from landfills or sites containing wastes of low methane generation rates. Studies have shown that microbial oxidation of CH4...
Chapter
The hydraulic conductivity of waste is an important parameter that influences the design of leachate recirculation system in a bioreactor landfill. The hydraulic conductivity of waste varies with respect to depth and time in a landfill. These variations can be attributed to the settlement of waste, and the corresponding changes in the void ratio ca...
Conference Paper
Full-text available
In this study, the environmental benefits and the feasibility of utilizing landfill gas as an alternative source of energy from two landfill sites of Bangalore and Mysore are evaluated. Bangalore generates around 4,500 tons of municipal solid waste (MSW) per day and the majority of this is collected and disposed in landfills. About 2.1 million tons...
Conference Paper
Full-text available
Bangalore generates around 3,500 tons of municipal solid waste (MSW) per day. The current waste management practices involve preliminary mechanical and biological treatment before landfilling. Assessment of the waste management practices followed by the municipality by using life cycle analysis (LCA) is presented in this study. LCA is also used in...
Chapter
Experimental studies on small-scale bioreactor landfills treating mechanically and biologically treated waste under aerobic and anaerobic conditions are presented in this study. The waste was collected from one of the Municipal Solid waste processing units of Bangalore City. The performance of the bioreactors in terms of organic content, gas emissi...
Article
The paper presents results of a comprehensive study on characterization of mechanically biologically treated waste generated in Bangalore, India. Physical, biochemical and engineering characteristics of the waste are presented. The methodology to separate the components of consolidation which includes primary, secondary and biodegradation strains i...
Article
The performance of an anaerobic bioreactor in treating mechanically biologically treated municipal solid waste was investigated using experimental and modelling techniques. The key parameters measured during the experimental test period included the gas yield, leachate generation and settlement under applied load. Modelling of the anaerobic bioreac...

... This technology is effectively used to restore environmental resources like water, soil and air (Sughosh et al. 2021). The bioreactor system comprises mechanical vessels in which microbes are cultured in controlled conditions. ...
... Ignoring the effect of artificial facilities on a regional scale would affect the accuracy of water level simulation results. For the numerical tools used to create groundwater flow models, mature commercial software and codes like MODFLOW, FEFLOW, POREFLOW, TOUGH3, and HydroGeoSphere (Cornelissen et al., 2016;Welch et al., 2019;De Caro et al., 2020;Santos et al., 2020;Parameswaran et al., 2021) was mainly adopted. Software and codes were generally selected by site conditions and research objectives. ...
... The leachate head increased marginally in this condition but is within the permissible limit. Recirculation of leachate enhances the waste degradation rate and Fig. 7 HELP model output for leachate collection and 50% recirculation (Reprinted from sughosh et al. [10]. With permission from ASCE) reduces the time required for stabilization of the waste. ...
... Recently, Gollapalli and Kota (2018) also investigated methane emission from the Boragaon landfill of Guwahati city using IPCC, MTM and LandGEM models and compared the methane flux with Gas chamber method. Sughosh et al. (2019) estimated maximum LFG flow rates using LandGEM version 3.02 for Mysore and Bangalore landfill sites respectively. Singh, Kumar, and Roy (2018) also reported total 1084 Gg methane emission for the year 2015 from an Indian landfill site and correlated LFG emission with gross domestic product (GDP) rate of the country. ...
... The existence of the reinforced layer and the increase of unit weight and particle size affected the cohesion and increased the internal friction angle. Lakshmikanthan et al. (2018) obtained the cohesion of 4-5 kPa and the internal friction angle of 32°-33° for 20% axial strain by triaxial test, which are lower than the c′ (18.04-27.94 kPa) and φ′ (31°-45°) of this study at 20% axial strain. ...
... Bio-mechanical treatment in European countries is mainly used for reduction of active biomass in the waste [2] or for stabilization of the landfill site [3] by more compacted mass after mechanical shredding. How efficient mechanical pre-treatment technologies are to sort out useful secondary materials was investigated by Meirhofer et al. [4], improving sorting schemas with spectral sensors in Austria. ...
