Application of Geographical Information System (GIS) in optimisation of waste collection for Alandur Municipality in South Chennai, India
The population outburst in urban areas had resulted in a substantial increase in the generation of Municipal Solid Waste (MSW) and challenged with waste management. Issam et al. (2007) pointed out that most of the cities which is burning the waste in open dumps lacks in proper health and safety requirements. Alandur which is under Alandur Municipal Corporation (AMC) generate nearly 80 MT MSW ...

Study on accumulation of non–biodegradable solid wastes along Ulhas River of Thane, Mumbai
With the spread of technology, industrialisation and increasing standards of living, the accumulation of non–biodegradable solid waste (NBDSW) is an unwelcome and often unnoticed side effect of 'development' in India. Therefore in the present investigation, attempts are made to quantify major non–biodegradable solid wastes viz. plastics, synthetic rubber and glasses which are accumulated at three ...

Multi–criteria decision aid approach for the selection of the best compromise management scheme for the treatment of municipal solid waste in Morocco
The Municipal Solid Waste (MSW) in developing countries is generally badly controlled and badly managed. Because of the environmental problems bound to this problem, many countries established their national legislation to determine types of reuse, recycling and treatment of waste, to apply the appropriate solutions. In this study, alternate schemes are examined and analysed aiming at the ...

Extent and rate of biodegradation of different organic components in municipal solid waste
Rates and extent of biodegradability of four different organic components of municipal solid waste (leaf litter, newspaper, magazine paper and A4 sheet) were evaluated under optimum conditions. Total solids (TS) removals in biotic samples ranged from 74.7% to 78.8% while volatile solids removals ranged from 75.7% to 84.8%. Significant biodegradation of tannin–lignin was observed for all four ...

Marketisation of public services in China: reforming the provision of solid waste services in Guangzhou's environmental sector
Since Municipal Solid Waste (MSW) collection and disposal has been a free public service in many Chinese cities, many local governments in China are facing the problem of insufficient funding. A number of municipal authorities in China have adopted marketisation (the Chinese equivalence for privatisation) to relieve local governments' financial burdens in solid waste management. This paper will ...

Anaerobic digestion of Organic Fraction of Municipal Solid Waste (OFMSW) in two-phase system
In view of recovering energy resource from the treatment of Organic Fraction of Municipal Solid Waste (OFMSW), anaerobic digestion of OFMSW prior to aerobic composting as post-treatment was considered. This study aimed to determine the operational characteristics and efficiency of a two-phase system composed of a fed-batch hydrolysis reactor (phase I) and a methanogenic Upflow Anaerobic Sludge ...

Alternative stabilisation options of mechanically sorted organic fraction from municipal solid waste prior to landfill disposal
In order to foresee the measures of the Directive 1999/31/EC, waste management policies are focused on the reduction of organic matter landfill disposal, through the recovering of the organic waste stream or the pre-treatment of residual wastes before landfilling. This paper discusses the advantages and disadvantages of possible stabilisation treatments of the mechanically sorted organic fraction ...

An eco–sustainable model on energy recovery from municipal solid waste
In the present day situation, the toxicity in municipal solid waste has increased to a very high level leading to various problems. The main purpose of the study is to improve the quality of mixed solid waste by adding locally available biomass. It was observed that the feedstock for refuse derived fuel and biomethanation contains 12% and 20% toxicity, respectively, as a result degrading the ...

Quantification of municipal solid waste for Patna city
Solid waste includes a good sphere of multidisciplinary source which reflects the life style of the people generating it and the existing process in solid waste management. In developing state of India, an inherent demand of resource increases the waste population that further aggravates the economics of Municipal Solid Waste (MSW) management system. In recent years, due to drastic increase in ...

Compatibility of compacted lateritic soil treated with bagasse ash and Municipal Solid Waste leachate
Compatibility tests were carried out on lateritic soil treated with up to 12% bagasse ash compacted at about 2% wet of their respective optimum moistures using the standard Proctor energy. Samples were sequentially permeated with distilled water and municipal solid waste (MSW) leachate for 22 and 69 days, respectively, until steady flows were established. The final hydraulic conductivity values ...

Composting vs. Recycling – Drawing a Line to Differentiate Between the Two Waste
Being a citizen of the modern day ‘Zero Waste’ community, a person needs to learn where to draw a line of differentiation between the items that need to be recycled and the ones that should be composted, or the unfortunate ones that must find their place in normal trash. Recycling and composting are the two environmental friendly methods for handling solid municipal waste. Using ...

Municipal solid waste: alternative source of energy to the cement kilns in the state of Madhya Pradesh, India
Rapid urbanisation has resulted in large–scale municipal solid waste (MSW) generation in India. Scientific and environment friendly disposal of MSW is a challenge for the municipal local bodies. A survey has been conducted regarding municipal solid waste generation from 342 local bodies in the State of Madhya Pradesh. Total generation of the MSW in the State is estimated around 4,500 MT/day ...

Urban environmental services: valuing the environmental benefits of solid waste recycling in Brazil
Taking into account environmental and economic aspects, this research aims at estimating the environmental services produced by municipal solid waste (MSW) recycling. The text values the urban environmental services associated with the recycling of steel, aluminium, paper, plastic and glass present in MSW in Brazil. Estimates indicate that benefits of current recycling rates reaches something ...

Changes in geotechnical properties of Municipal Solid Waste (MSW) in bioreactor landfill with degradation
The objectives of the research described in this paper are to: study the composition of fresh Municipal Solid Waste (MSW); study the effects of decomposition on physical characteristics of MSW in bioreactor landfill. Initially, composition of the fresh MSW constituents was determined based on 14 bag MSW samples. Then, four small-scale bioreactor landfills were simulated in laboratory and samples ...

Anaerobic Digestion technologies for the treatment of Municipal Solid Waste
Anaerobic Digestion (AD) of Municipal Solid Waste (MSW) is used in several regions worldwide and systems span a range of design options including wet, dry, thermophilic, mesophilic, batch, continuous, single-stage, and multi-stage configurations. This paper reviews a number of commercial and emerging solid waste digestion systems discussing performance and costs. Systems yield 250?710 m³ of ...

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) ...

Evaluation of a sequential aerobic?anaerobic treatment of municipal solid waste in a bioreactor landfill
A sequential aerobic-anaerobic bioreactor landfill was operated and monitored over a period of 184 days. The bioreactor was filled with 120 kg of organic fraction of Municipal Solid Waste. Leachate recirculation was applied. The results showed rapid degradation of organic matter with rapid settlement during the aerobic period. The initial COD and BOD5 were reduced from 46,500 and 41,500 mg/L to ...
