“…The present annual quantity of solid waste generated in Indian cities has increased from six million tons, in 1947, to 48 million tons, in 1997, and to 90 million tons in 2009; this is expected to increase to 300 million tons by 2047 [1][2][3]. This massive increase in the amount of municipal solid waste (MSW) generated is because of changing lifestyles, food habits, and the standard of living of the urban population [4]. The characterization of MSW has indicated that the waste consists of 30%-45% organic matter, 6%-10% recyclables, and the rest is inert matter [5].…”

“…Composting plants are not presently operating to their intended treatment capacities. In the absence of leachate and landfill gas collection systems, these landfills are a source of groundwater contamination, as well as of air pollution [4]. The low calorific value of waste, the presence of inert material, as well as construction and demolition waste in municipal solid waste, makes it inappropriate for incineration of waste for energy production.…”

“…The purpose of Bhagidari was to develop awareness, public participation, and to improve segregation and the primary collection of the waste [4]. However, it failed to introduce segregation due to a lack of public cooperation [11].…”

Abstract:Delhi generates about 8360 tons of municipal solid waste per day, and there is low compliance to rules regarding waste management. The objective of this paper was to understand the situation in Delhi with respect to the segregation, storage, collection, and disposal of household waste, and to assess the knowledge of the residents of Delhi, and their willingness to engage in solid-waste management. A stratified random sample, comprising 3047 respondents, was chosen for a questionnaire survey, covering all municipalities of Delhi, with socio-economic classification as the stratifying variable. Survey results indicate that 60% of residents do not know the difference between biodegradable and non-biodegradable waste, and only 2% of them segregate waste. Fifty-eight percent of respondents reported that the waste collector mixes the segregated waste, 97% of respondents reported that they sold items to an itinerant waste buyer, and 87% of households are covered by doorstep waste collection services. Abstract knowledge (general knowledge about waste management) is seen to have a significant correlation with willingness to engage in waste management. Differences between the socio-economic groups indicate that the highest (most educated and wealthy), as well as the lowest socio-economic category (least educated and poor), older age-groups, and women, have greater abstract knowledge. Socio-economic categories having higher abstract knowledge can be active participants in decentralized models of waste management.

“…Several works in the literature (Ramos et al, 2013;Guerreo et al, 2013;Talyan et al, 2008;Rockson et al, 2013;Medina, 2000) presented a conflict situation between local government, population and waste pickers. Therefore, this work presents the results of a case study based on the participation of formal scavengers in the municipal waste management of Caxias do Sul city.…”

Abstract:Solid waste management is becoming a challenge for the cities' authorities in developing countries mainly due to the rapid economic growth and population increasing. In cities of the developing world, the informal sector plays an important role in the management of urban solid waste. This work examines the participation of scavengers in an integrated municipal solid waste management system. The paper is based on direct field observations, interviews with scavengers and characterization of the urban solid waste generated in Caxias do Sul. The partnership between municipal government and local scavengers were also evaluated as well as the contribution of the scavengers in the urban solid waste management system. The study reveals that it is necessary to realize a campaign for improving the waste segregation at source. The infrastructure of the scavengers associations need to be improved and finally the scavengers need to be more deeply involved in the policies associated with the urban solid waste management system adopted in the city.
