Management of solid waste is a major challenge for most of the urban local bodies in developing countries primarily due to the rising urban population and per capita waste generation rate. Improper management of municipal solid waste leads to repulsive condition of streets and spreading of diseases. The present study is an attempt to evaluate the user satisfaction on the performance of the Greater Visakhapatnam Municipal Corporation (GVMC) with regard to solid waste management. The findings of the study are going to be useful to the urban local bodies and GVMC in particular to identify the performance gaps and to initiate measures for further improvement.

The present study, dealing with the inequality in consumption of the rural households across the different regions, is based upon the primary data of the Punjab state. The analysis showed that Malwa excelled other two regions in the per capita consumption. The highest average propensity to consume was observed for Doaba, and it was the lowest for Malwa. All the rural households except large farm of all the three regions and medium farm households of Malwa and Majha were in deficit. Considering all households together, the inequality of household consumption expenditure was relatively high in all three regions, with the same being highest in Majha, followed by Malwa and Doaba. The concentration of consumption expenditure among the land-owning households was greater than the landless households.

Msw Composition

Municipal Solid Waste (MSW) disposal has become an increasingly serious problem in many parts of the world. In general, greater economic prosperity and a higher percentage of urban population correspond to a greater amount of solid waste produced. However, less effort has been exerted in the proper management of solid wastes produced by urban dwellers, particularly in developing countries. This chapter introduces the basic MSW rules. MSW composition, production, and collection are also highlighted. Furthermore, the concept of landfilling and waste decomposition is discussed in this chapter.

Waste Gasification

In Brazil, in 2016, 196,050 tonnes day-1 of municipal solid waste (MSW) were collected, which means a waste generation of 1.035 kg per capita per day. Only 59.1% of the waste has adequate destination in sanitary landfills, whereas the remaining 40.9% has inadequate destination in controlled landfills and open dumps (ABRELPE, 2018). Among all the states in the country, the State of São Paulo has the biggest per capita generation: 2.290 kg. Today, the only waste destination practiced in the country is deposition in landfills, but other possibilities can be considered. Among thermal treatment routes, the gasification of MSW is an interesting alternative to be studied, because of its versatility and relatively low emissions. The aim of this work is to evaluate the potential of electricity generation through MSW gasification in Santo André city, Brazil, comparing three waste gasification technologies: TPS Termiska Processer AB, Carbogas and Energos. These alternatives have operated commercially for a few years, and data are available. Specific characteristics of each technology were taken into account, such as the reactor type and fuel properties. For the electricity production scheme, two energy conversion systems were assumed: an internal combustion engine and a steam power cycle. From the process parameters adopted, the results showed that Carbogas technology, coupled to internal combustion engines, presents the highest efficiency of electricity generation (30%) and also the lowest cost of electrical energy produced (US$65.22 MWh-1) when Santo André’s gate fee is applied.

Capita Disposable Income

Based on the IPAT model, this study selects the two-order lag period that is then applied to the dynamic model created to explore the impact of China’s urbanization on the quantity of municipal solid waste (MSW) produced. The study uses panel data collected from 27 provinces, autonomous regions, and municipalities in China that report directly to the central government. Results show that nationwide urbanization and urban per capita disposable income are positively correlated with the quantity of MSW produced. However, specifically, urbanization in the eastern and midwestern areas of China is insignificantly correlated with the quantity of MSW produced. It is, therefore, recommended that citizens should make sensible and environmental consumption decisions based on per capita disposable income. It is also suggested that quality development and Stead’s urbanization plan should become national policy, and that MSW categorization and a recycling policy should be implemented to treat MSW effectively.

While Kerala has been hailed for its development in social sectors, the available data show the remarkable finding that Kerala’s morbidity is the highest in India. Literature reveals two major streams of argument for this, one questioning the comparability of the reported rates of morbidity and the other admitting that the higher rates of morbidity actually represent the situation.  The present study analyses the pattern of morbidity in Kerala, tries to analyse the morbidity pattern and finds out the reasons for highest morbidity in highest Monthly Per Capita Consumption Expenditure (MPCE) group and lower morbidity in ST households. The paper argues that the prevalence of lifestyle diseases among highest MPCE group is one critical reason for the high morbidity rates in Kerala. It also proposes urgent interventions on behalf of the government that can effectively counter the high rates of infectious diseases among ST households.

Current waste management strategies are shifting from waste disposal to recycling and recovery and are considering waste as a potential new resource. This paper aims to quantify reusable and recyclable fractions with status of material recovery from municipal solid waste (MSW) in Kathmandu Valley of Nepal. 550 households, 110 institutions and 110 commercial establishments were sampled to compute the generation, composition and quantify reusable and recyclable fraction of solid waste. In addition, 120 scrap shops were surveyed randomly from Kathmandu Valley to estimate the amount of resource recovered for economic benefits. As per results, the average per capita MSW generation can be estimated at range of 0.25 kg day-1 to 0.47 kg day-1 in municipalities of Kathmandu Valley. Based on these generation rates and population for the year 2011, the total MSW generation of the five municipalities of Kathmandu Valley was estimated to be 620 metric tonnes day-1. The major content of reusable and recyclable materials in MSW comprised with an average of 44% that is equivalent to 271 metric tonnes day-1 among which only 52% (i.e. 140 metric tonnes day-1) of these materials were found to be recovered during survey. The key materials that have been recovered are papers, plastics, metals, glasses, and batteries. Recovery of reusable and recyclable materials not only helps to minimize the quantity of solid waste for land filling, but also provides a potential source of livelihood for the urban poor.

Municipal solid waste (MSW) characterisation across socioeconomic residents is necessary for planning sustainable solid waste management. In view of planning for Kumba municipality in the South West Region of Cameroon, three types of socioeconomic residents classified as low, medium and high income residential areas were randomly sampled. In each residential area, 32 households were sampled following systematic random sampling. Over a period of eight weeks within three periods characterised with varying activities, statistically designed number of samples for waste composition were hand sorted and weighed at source of generation. The study revealed that the per capita generation of putrescible and miscellaneous wastes (predominantly sand, ash and dust) were statistically different (p < 0.05) across residents and were inversely related to income while the generation of plastics, metals, papers, glass except textiles were statistically different across residents and were positively related to income. Putrescible waste was the most predominant waste category constituting more than 75% across residents. No significant differences were observed for per capita waste generation across residents during the entire period of study and within residents during the different periods over which the waste categories were measured. However, within the different periods, waste generation was significantly different across residents with more waste being produced in low income residents. The waste density was found to decrease with increasing income. The observed variation of waste generation and composition has implications for collection frequency, equipment needs, composting and digestion of the biodegradable for biogas generation to sustain the solid waste management sector.
