I. INTRODUCTION

Nagpur is the winter capital and the third largest city of Maharashtra and largest city of central India. It has one of the highest literacy rates of 91.92% among all the urban agglomerations in India. NMC divides city in 10 zones and each zone is divided into several wards. As per provisional reports of Census India, population of Nagpur in 2011 was 2,405,665; of which male and female are 1,225,405 and 1,180,260 respectively (Census Nagpur, 2011).

Solid Waste Management is todays emerging issue for the safe environment and healthy life. The primary goal of solid

waste management is reducing and eliminating adverse impact of waste on human health and environment to support economic development and superior quality of life.Waste generation has increased day by day due to increasing population, industrialization and urbanization.

The most important point in which we are lagging in implementation of waste management projects is public unawareness. People in Nagpur are not aware about segregation of household waste which is main step involved in waste management. In this paper, we have given the various types of waste generated under solid

waste, their contribution in total waste generated, current news related to upcoming projects. Solid waste is categorized as household waste,

electronic waste and biomedical waste. The household waste contains food, paper, plastic, glass waste etc. In India, the 45% of waste is biodegradable, 13% is electronic waste, 11% is metal & glass and about 13% of waste consist of inert materials.

According to a survey by ABP News-Ipsos, Nagpur was identified as the best city in India topping in livability, greenery, public transport, and health care indices in 2013.The city was adjudged the 20th cleanest city in India and the top mover in the western zone as per Swachh Sarvekshan 2016. It was awarded as the best city for innovation and best practice in Swachh Sarvekshan 2018. It was also declared as open defecation free in January 2018 under Swachh Bharat Mission. It is also one of the safest cities for women in India. The city also ranks 31st in Ease of Living index among 111 cities in India.It was ranked the 8th most competitive city in the country by the Institute for Competitiveness for the year 2017.
