Municipal solid waste management in Jodhpur city, Rajasthan (India) - current status
Jodhpur city is the second largest city of Rajasthan State, having population of about 1,077,717 and an area of 232 sq km. The city generates around 380 t/d of municipal solid waste (MSW). With the increase in population, urbanisation and industrialisation, the problems of handling MSW have significantly increased in the past few years. There is no arrangement for segregation of waste at source. ...

Fuelling ultra light rail public transport from a Gloucestershire organic waste treatment plant: a feasibility analysis
Many medium-sized towns and cities face separate problems of traffic congestion and increasing pressure to reduce waste sent to landfill. The intent of the study was to determine whether the utilisation of biohydrogen from organic waste, as a transport fuel, can provide a holistic solution for municipalities to meet renewable energy and waste reduction targets in medium-sized towns. The study ...

The modelling of biochemical–thermal coupling effect on gas generation and transport in MSW landfill
The landfill gas generation was investigated based on the theories of the thermodynamics, microbial dynamics and chemical dynamics. The coupling model was developed for describing the gas transport and heat release. And the relationship between the gas generation rate and the temperature was proposed. The parameters in the gas generation model were obtained by bioreactor test in order to evaluate ...

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 ...

Russia is building new sanitary landfills – how to prolong their lifecycle from the start?
A high-quality landfill compactor is the minimum requirement when operating a safe, sanitary, and profitable landfill. However, to really maximize profitability, a mobile slow-speed industrial waste shredder is a great next step. With the right equipment, you can process waste to extend the lifecycle of a sanitary landfill and get profit from recovering valuable materials from municipal solid ...

MSW recycling as a mechanism for the social inclusion in Brazil
This paper presents an evaluation of the recycling as a mechanism that can promote the social inclusion in Brazil. The analysis is based on the data from a Brazilian metropolitan, city of Campinas and is extended to Brazil. The results show that the municipality of Campinas collects monthly 8000 tons of recyclables, which if recycled can avail jobs to nearly 5000 waste collectors each receiving a ...

Waste dynamics, decoupling and ex post policy effectiveness: evidence from the EU15
This paper provides a comprehensive analysis of municipal and packaging waste generation dynamics, based on panel data for the EU15. The evidence provides some valuable policy implications since it analyses the extent to which decoupling has occurred for the two waste streams and if and how effectively EU waste policy has influenced the waste generation-income relationship since 1995. We ...

Optimization model for integrated municipal solid waste management in Mumbai, India
Mumbai, the largest metropolitan city in India, generated 6,256 tons of waste per day in 2001. It is the responsibility of the Municipal Corporation of Greater Mumbai (MCGM) to provide Municipal Solid Waste (MSW) management services; however, the MCGM is not able to handle the increasing quantity of waste. As a result, waste litters all over the place giving rise to health and environmental ...

Role of final cover soil in regulating volatile organic compounds: emissions from solid waste disposal sites in developing countries
The objective of this study was to investigate the emission of Volatile Organic Compounds (VOCs) from solid waste disposal sites and their remediation at final cover soil. This research was conducted using field cover soil lysimeters placed at the surface of a solid waste dumping area and batch experiments in the laboratory. It was found that benzene, toluene, chloroform and perchloroethylene ...

Remediation of heavy metals from urban waste by vermicomposting using earthworms: Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
This study revealed that three earthworm species, viz., Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus, through vermicomposting remediated heavy metals - Pb, Zn, Cd, Cu and Mn from the urban waste - organic fraction of Municipal Solid Waste [M(O)SW], vegetable Market Waste (MW) and Floral Waste (FW). The concentrations of Zn, Cd and Cu were 36.1, 50.9 and 70.2% higher in M(O)SW compared ...

Low cost pre-treatment of waste landfill emissions - does mechanically-biologically treated waste facilitate the operation of low environmental impact landfills?
Rules and regulations contained in the German Federal Waste Management Act are specified and complemented in administrative directives. One of them is the so called ”Technische Anleitung Siedlungsabfall” (TASi), in other words the Technical Directive for Municipal Solid Waste, which stipulates criteria for the use, treatment and disposal of waste materials. Where it is not possible to ...

New model of municipal solid waste management
In the current scenario, the waste is an indicator of socioeconomic development. So, the more booming economy is, the greater the volume of produced waste. The downside of this scenario is the result of technological bottlenecks of conventional management models. In this context, this paper discusses and proposes a new model for urban solid waste (USW) management, based on the ...

Daily Cover Challenges and Solutions at Puente Hills Landfill
Abstract Time constraints in working with daily cover have been among the main concerns at Puente Hills. The landfill serving Los Angeles County California was one of the world’s largest, and has until recently received up to a maximum allowable daily limit of 13,200 tons (12,000 tonnes) of municipal solid waste a day. With that waste intake and being a “canyon fill”, large and ...

Waste management facility expansion planning using simulation–optimisation with grey programming and penalty functions
Simulation–Optimisation (SO) techniques, which incorporate inherent system uncertainties using probability distributions, have been used for optimal waste management planning. While SO can be applied to numerous stochastic problems, its solution times vary considerably from one implementation to the next. In this study, SO has been concurrently combined with both penalty functions and a Grey ...
