Sustainable development is a major concern for developing nations as they strive to preserve their ecological balance along with economic growth. It has been noticed that economic growth results in environmental degradation as it influences lifestyle practices and leads to increased consumption of goods thus generating the large volume of municipal solid waste. Patna, the capital city of Bihar, is an ideal example of this condition. Here, central and local government and pollution committees fail to effectively tackle the large and increasing volume of municipal solid waste. Such scenario of municipal solid waste management in the city can cause serious health hazards, environmental degradation, and ecological destruction. Recycling the inorganic fraction of municipal solid waste can reduce the threat. In the present study, based on an extensive literature review propose a theoretical sustainable recycling model for Patna. This model is based on the similitudes in the recommendations required to attain ‘sustainable development’ and ‘sustainable recycling’. Sustainable recycling model has six gears drive by various variables. Each gear has been tested for its existence in Patna. As a result, ‘social aspect gear drive by three variables in sustainable recycling model is public health; public awareness; health of workers involves in recycling’ shows complete non-existence behaviour. Hence, a survey ( n = 127) has been performed to evaluate the success factors for social aspect gear existence in sustainable recycling model. Multivariate statistical analysis has been executed the comparison of respondents’ perception on success factors and success factor groups affecting sustainable recycling of municipal solid waste in Patna. The study contends that if the proposed model has been successfully applied, then the problem of municipal solid waste can be effectively addressed.

“…However, its exploitation in these areas presents several health concerns as a result of possible contamination associated with urbanization. Similar to other African countries, possible contamination can arise from sewage intrusion from septic systems and latrines, indiscriminate disposal of waste, agricultural runof, and natural factors [9][10][11].…”

Groundwater sources provide an important supply of alternative drinking water in most urban areas in Malawi. This study was conducted to assess the quality of groundwater in Area 25, a typical urban residential area in Malawi. Samples were collected from wells and analyzed for physicochemical and bacteriological parameters following standard methods. Results were compared to Malawi Standards (MS) and World Health Organization (WHO) drinking water quality guidelines. The overall water quality index was computed to ascertain the general quality of the water. Levels of pH, phosphate, sulfate, arsenic, lead, and potassium were below the guideline limits while, electrical conductivity, total dissolved solids, chloride, fluoride, nitrate, total hardness, calcium, and magnesium were observed above permissible limits, posing a health risk to the residents. The quality index ranged from 22 (excellent quality) to 64 (Poor quality) with an average of 41 (good quality). Fecal coliforms were present in 70% of the sampled locations with an average of 7.9 cfu/100 ml. The presence of these bacteria presents a serious risk for waterborne disease outbreaks. This study, therefore, recommends the provision of basic treatment techniques to improve the quality of water in the area before consumption, regular monitoring of groundwater resources, and proper design and setting of septic systems.

“…The rate of urbanization has improved quality of life but at same time it has adverse effect on environment. Urbanization is increasing the level of air, noise, water pollution and solid waste generation their complexities 2 . Few decades ago, environment was not of any concern of scientific efforts for developing countries like India and even solid waste management was not prime concern in developing countries.…”

Solid waste management is one of the biggest issues in India as well as in the world. The generation of solid waste should be estimated for proper management of municipal solid waste (MSW) of the cities. The segregation, collection, transportation and disposal of MSW are currently done in very unscientific and causal way in India and in many other developing countries. This creates problem for environment in terms of water, air and odour pollution. In this study, the characteristics of MSW have been estimated for Patna city and management has been carried out for recovery of resources. The components of MSW have been estimated and based on that, moisture, density and energy content have been quantified. Afterwards, chemical compositions have been calculated and chemical formula has been made for MSW. This composition can help to estimate requirement of oxygen to degrade MSW and recovery of methane and carbon dioxide from MSW. Generally, landfill for solid waste management is planned for fifteen years or more than that. It is carried out in several parts or layers which take many years. In this paper, the calculation of energy content, requirement of oxygen to degrade MSW and recovery of methane, carbon dioxide from MSW have been carried out for a year which can be done for whole landfill period.
