Evaluation of cost benefit analysis of municipal solid waste management systems
No full textThe rate of municipal solid waste (MSW) generation in developing countries is continuously growing in proportion to the gross national product. Landfilling, incineration, composting, and waste to energy (WtE) have a brief history as management strategies for MSW in India. Economic evaluation via cost benefit analysis (CBA) of MSW is establishing the most appropriate treatment/disposal strategy and it is often a major concern for solid waste management (SWM) policymakers. Thus, this study aims to analyze the municipal solid waste management (MSWM) activities in India's capital, Delhi, and the CBA of MSWM systems to identify the major problems and limitations involved. Sixty-six samples totaling 6,600 kg were collected and analyzed at random from various locations, including the sources of generation, composting plants, and disposal sites. Storage, collection, transportation, and recycling information were gathered from departments such as Municipal Corporation of Delhi (MCD), New Delhi Municipal Corporation (NDMC), Central Pollution Control Board (CPCB), and self-surveys. The total costs of each MSW option were calculated for cost analysis. The results revealed a high organic moisture content, indicating the possibility of composting and bio-methanation, except for waste from commercial, institutional area and restaurants that can be used to develop Refuse Derived Fuel (RDF). It was also revealed that only about 80% of the garbage generated in Delhi is collected. In terms of treatment and disposal, the MCD has proposed additional facilities such as disposal through sanitary landfills with linings, as well as a system for leachate collection and disposal. Furthermore, construction and demolition waste are used in the construction of various pavement components, such as base coarse, surface coarse, and so on. The total social value added by garbage trade operations in Delhi is expected to be INR 358.7 crores (approximately 46.60 million USD) between 2017 and 2020. Recycling saves the municipal budget about INR 17.6 crores (approximately 2.3 million USD per year).(c) 2022 The Author(s). Published by Elsevier B.V. on behalf of King Saud University.

A Study on the Landfill Leachate and Its Impact on Groundwater Quality of Ghazipur Area, New Delhi, India
No full textNoise pollution mitigation and control in urban areas near international borders through 2D noise mapping
No full textAbstract Noise pollution is defined as any disturbing or unwanted sound that disrupts or harms human health or wildlife. Noise pollution can have profound effects on both human health and the environment. For humans, exposure to excessive noise levels has been linked to a range of health issues, including hearing damage, stress, and sleep disturbances. Noise monitoring and mapping play a crucial role in understanding, managing, and mitigating the impacts of noise pollution on communities and the environment. Urban areas near borders are generally less studied due to restrictions. Therefore, a study has been conducted aiming the monitoring of noise level and looking into its propagation through 2D noise maps in the urban areas of Jammu and Kashmir lying near the Indian border. The monitoring results revealed that even boarder areas are exposed to high noise levels. Bhatindi in Jammu city recorded highest equivalent noise level, Leq of 91.2 dB(A) during evening. Nowshera is calmest among other study area with noise level, Leq of 80.1 dB(A). Further, 2D noise mapping showed some critical locations in study areas of Jammu and Kashmir that the noise propagates to the nearby residential and commercial areas which require immediate remedial measures. The findings not only contribute to the scientific understanding of noise patterns in border regions but also hold practical implications for urban planning, public health, and environmental conservation
