Municipal Solid Waste Management and its Energy Potential in Roorkee City, Uttarakhand, India
Journal of The Institution of Engineers (India): Series A, 2016
Energy plays a vital role in the development of any country. With rapid economic growth and multifold urbanization, India faces the problem of municipal solid waste management and disposal. This problem can be mitigate through adoption of environment friendly technologies for treatment and processing of waste before it is disposed off. Currently, urban and industrial wastes throughout India receive partial treatment before its final disposal, except in few exceptional cases. This practice leads to severe environmental pollution problems including major threat to human health. There is an absolute need to provide adequate waste collection and treatment before its disposal. Municipal Solid Waste (MSW) is getting importance in recent years. The MSW management involves collection, transportation, handling and conversion to energy by biological and thermal routes. Based on the energy potential available, the energy conversion through biogas production using available waste is being carried out. Waste-to-energy is now a clean, renewable, sustainable source of energy. The estimation of energy content of MSW in Roorkee city is discussed in this paper. Furthermore this paper also takes into account the benefits of carbon credits.
Study of municipal solid waste of Delhi for energy content
Solid waste management has become a global problem. Littering of wastes on streets not only causes inconvenience and aesthetic problems, but also has a lot of impact on human health Municipal Solid Waste Management (MSWM) is highly neglected aspect of Delhi. At present approximately 6000 tons of waste is generated per day which is disposed in the three existing landfills. The three landfills are almost saturated therefore some alternate method of disposal should be designed. The present paper discusses the energy content of MSW of Delhi so that some suitable technology can be adopted for the disposal of wastes. Generally evaluation of the heating value of Municipal Solid Waste (MSW) is done experimentally by using bomb calorimeter and theoretically by using Dulong’s equation. In this paper, regression analysis is used to develop a predictive model of the energy content for MSW of Delhi.
Waste to Energy-Current Practices and Potential in India
Solid waste generated at domestic level is the single largest component of all wastes generated in our country. A number of research studies have shown that somewhere 300 to 600 gm of solid waste is generated per person per day in our country. Eventually, Municipalities everywhere face the problems of waste collection, processing and disposal or treatment of voluminous solid waste produced by the cities. Moreover, the rains and humidity on the garbage promotes the bacterial multiplication and enhances the spread of infectious diseases. However, due to their rich organic contents, the solid waste can be a good resource to produce manure & energy. It has been estimated that about 70 MW equivalent power could be generated from urban & municipal waste alone. This potential is likely to increase further with our economic growth. The present study includes the current practices of waste to energy in various cities of India. Also challenges and suggestive measures are presented for these cities in this field to achieve sustainability.
Utilization of Municipal Solid Waste of Gwalior City for Energy Generation (A Case Study)
2016
Gwalior is the large city of Madhya Pradesh region which is located 319 kilometers south of Delhi a capital city of India .The population of Gwalior is 1159032 as calculated by ICLEI in Aug 2015. The MSW generated in the city is around 380 tonnes and about 80 % of MSW is collected per day from the various collection points in the city. The uncontrolled and unscientific dumping of such waste has brought about a rising number of incidents of hazards to human health. Based on the Quantum and Quality of MSW generated in Gwalior, Various technological options to recover energy from solid waste are available like Incineration, Pyrolysis, Anaerobic digestion & Landfill gas recovery. The waste composition of Gwalior city mostly shows organic matter approx. 55 %. Wastes to Energy technologies are able to derive renewable energy from organic matter present in municipal solid waste. By using various WTE technology the energy can be recovered in the form of Electricity (i.e. power), Heat, Fuel, Biogas (Methane) ,and Syngas with additional byproducts such as fertilizer from digested sludge and the Ash content which is used for construction material.
Electrical Energy Potential from Municipal Solid Waste in Rajshahi City Corporation, Bangladesh
This paper presents the assessment of the electrical power generation potential from municipal solid waste (MSW) in Rajshahi City Corporation (RCC), Bangladesh. RCC generates huge amount of solid waste (SW) which is left very poorly managed due to crisis in governance. About 80% of organic food wastes are the major constituents of SW generated in RCC in the year 2012. Electrical energy can be produced from SW generated in RCC as a sustainable commercial solution. The average calculated value of heat content of MSW of the year 2012 based on the data of MSW of 2005 (MSW: 2005) and MSW of 2012 (MSW: 2012) is 7234.5 kJ/kg, which is sufficient to produce electricity. Integrated sustainable waste management (ISWM) has to be put into operation to harness energy from MSW. A 645.543 ton/day energy recovery Mass Burn Incinerator (MBI) system of 19.71% overall efficiency is to be used. It is found that potential of electrical energy generation from MSW in RCC during the years 2012 and 2025 is 5.336 MW and 10.568 MW respectively.
The Sustainable City VIII, 2013
In Delhi, in recent years, central, state and local level authorities have moved firmly towards the goal of scientific and sustainable management of solid waste generated from homes, offices and commercial establishments. A major initiative has been the decision to construct three waste-to-energy (WTE) projects. The government has pushed forward, despite the protests of environmental researchers and citizen groups who say these involve flawed, outdated and costly technologies which will add to pollution and erode livelihoods of the some of the poorest people in the city, without impacting much on its sanitation. Given the low calorific heterogeneous nature of the waste, they maintain, there is no alternative to waste reduction, composting, recycling and landfilling of residues. This paper will suggest that if the solid waste management hierarchy which expresses the spirit of the consensus that was arrived at in Rio de Janeiro in 1992 is the criterion, then, after two decades of economic reforms, WTE with its basis in advanced technology is an appropriate waste management strategy choice for Delhi. With the commissioning of the Okhla plant in January 2012, controversies relating to WTE regularly make the news. It is important that authorities address these concerns through appropriate measures such as transparent emission monitoring mechanisms and legal protection and benefits for waste workers in the informal sector. Dearth of land to accommodate mounting levels of mixed waste is creating an oppressive situation for urban planners in the developing world. Delhi's endeavour to resolve this problem by installing WTE facilities with the avowed object of enhancing public health, environment quality and economic efficiency and, as of now, staying with this decision, can be instructive for them.
A Survey on Waste to Energy Potential in Odisha
2017
Urban human habitation discharges unwanted materials, refuses and waste of heterogeneous mixture. Collection and removal of these municipal wastes are the primary duties of the urban local bodies in order to make the urban life as well as the environment free from pollution. The Environment (Protection) Act, 1986 compels for management of this municipal solid waste effectively. Management of MSW involves the processes like collection, treatment and final disposal. Treatment of Municipal solid waste by way of waste to energy conversion has proved that the energy generated from solid wastes contributes substantially to the total energy demand of the country and source of renewable energy. As per the statistics from MNRE, as much as 62 million tonnes of municipal solid waste is generated annually in India. In Odisha the figure is 2239 tonnes per day (2012). As per data, 100 tonnes of raw MSW with 50-60% organic matter can generate about1-1.5 MW power depending on the waste characterist...
Studies On Energy Recovery From Municipal Solid Waste; A Case Study At Solapur, Maharashtra, India
The generation of Municipal Solid Waste (MSW) is expected to rise tremendously in the coming decade due to the rapid urbanization and growth in population. On average, 75%–85% of the weight of MSW is converted into RDF (Refuse Derived Fuel). The RDF values in the MSW range from 4800 – 6800 Btu/lab along with the other benefits like its higher heating value, more homogeneous compositions, lower pollutant emissions, reduced excess air requirement during combustion, easier storage, handling, and transportation. In present investigation, the efforts were made to identify different compositions of organic solid wastes which have remained neglected as an alternative source of energy. These waste samples from Solapur city were collected, segregated, dried, crushed and pellets were prepared which were further tested for their energy contents. The results reveal that, in market waste the calorific value was 1754 Kcal/Kg, in paper waste 543 Kcal/Kg, in household waste it was 927 Kcal/Kg and in municipal solid waste after separating digestible leaf litter was 1940 Kal/Kg. It is concluded that the municipal organic waste based fuel pellets are good supplementary fuel energy source for small scale energy needs.
