Abstract - Waste treatment and management has now
become a crucial problem due to the inadequate and insufficient collection, disposal and treatment techniques, we are facing a severe problem of environmental pollution. It is the duty of the local governing authorities to provide proper solid waste treatment and management techniques in order to keep our city hygienically clean and environmentally healthy. Even though disposal of the solid waste has become a serious techno-economic problem for treatment, Kagal Municipal Council is working & planning towards making the city clean. One method used in order to reduce this grave problem of disposal is the conversion of the wet waste to electricity. This paper includes the technology adopted by the Kagal Municipal Council that involves the utilization of the solid waste generated as a resource for the generation of electricity. This paper includes everything right from the way collection of solid waste is done to the generation of electricity using the anaerobic digester. Key Words: Solid waste management, anaerobic treatment, methane, electricity, manure.
1. INTRODUCTION Rapid urbanization and industrialization in India has led to the migration of people to towns and cities thus generating thousands of tons of Municipal Solid Waste (MSW) daily. According to the 2015, CPCB report, the estimated solid waste generation in the country is around 1.43 lakh tons per day. The report said that cities like Pune, Mumbai, Ahmedabad, Agra, Bangalore, Bhopal, Chennai, Delhi, Hyderabad, Jaipur, Kanpur, Kolkata, Lucknow, Nagpur and Surat, among others, have an estimated waste generation of more than 500 tons per day. Poor collection, inadequate transportation and insufficient space to treat the waste of entire city are responsible for the accumulation of MSW at every corner. Unscientific disposal and treatment has lead to an adverse impact on all components of the environment and human health. Solid wastes are usually defined as the organic and inorganic waste materials produced by various activities of the society and which have lost their value to the first user. Rapid increase in population has lead to the © 2017, IRJET

increased rate in waste generated from several sources such as domestic wastes, commercial wastes, institutional wastes and industrial wastes etc. Rapid population growth and increase in per capita waste generation have resulted in a 50% increase in the waste generated by Indian cities within only a decade since 2001. There are 53 cities in India with a million plus population, which together generate 86,000 TPD (31.5 million tons per year) of MSW at a per capita waste generation rate of 500 grams/day. Such a steep increase in waste generation has severed the stress on all available natural and budgetary resources.
1.1 Kagal Solid Waste Treatments Kagal situated 12 km from Kolhapur city (16.58°N 74.32°E) is a historically rich city located in the south west of Maharashtra State. Kagal has the honor of having the first textile cluster (5star MIDC) in western Maharashtra. Kagal has been on the tourist map of India, both Hindu and Muslim pilgrims visit the famous Gaibee Peer. The Kagal Municipal Council is collecting 10 to 11 Tons MSW per day. The average waste generation is only 200gm per capita per day. The city is registering almost 15% extra growth rate compared to similar other cities in India. This is leading to rapid development of real estates, housing, complexes etc. Consequently the per capita MSW quantity has been estimated to reach 300 gm/day by 2016 as per DPR. The present population as per census 2011 is 35,075. The population growth rate of the city during the last decade has been 35% according to this calculation the estimated population in 2016 will be 47,351 and by the year 2032 it will be 63,993. Keeping above facts in view the projected quantity of MSW is 10 TPD by the year 2016 and 22 TPD by the year 2032. KMC is doing collection & segregation on its own. Collection and transportation includes door to door collection of solid waste through Ghanta Gadi and transportation to Municipal Solid Waste Treatment Facility center. Solid waste is collected from 6000+ households in 17 wards of the city through 6 vehicles. Approximately 14-15 trips per day are done by these vehicles.
