background and objectives: hospitals usually generate large amounts of hazardous waste. if not managed properly, hospital waste can pose threats to public safety and damage the environment. waste minimization is a waste management approach that focuses on reducing the amount and toxicity of hazardous wastes. this study pursues a two-fold purpose: 1) to gain insight into hospital waste minimizat...

context:  medical waste(mw) is all waste materials generated at health care facilities. mw mw naturally is hazardous for environment and subsequently for human.waste minimization (wm) is the latest alternative for risk reduction. all hospital staff generally and nurses specially can play an active role through education and the implementation of measures to reduce medical wastage and their envi...

Measuring resource efficiency can be achieved using different methods, of which primary energy demand is commonly used. The primary energy factor (PEF) is a figure describing how much energy from primary resources is being used per unit of energy delivered. The PEF for nuclear power is typically 3, which refers to thermal energy released from fission in relation to electricity generated. Fuel l...

Every human activity creates waste (Tciiobanoglous et al., 1993). India is the second most populous nation in the world; the uncontrolled growth of urban areas has led to deficiency in infrastructural services such as: water supply, sewage and municipal solid waste management (MSWM). The burgeoning population has resulted in a massive pressure on the health-care services, leading to huge amount...

The paper discusses the characteristics of leachate generated from municipal solid waste landfilling sites of Ludhiana City, Punjab (India). Leachate samples were collected and analyzed for various physico-chemical parameters to estimate its pollution potential. This study aims to serve as a reference for the implementation of the most suitable technique for reducing the negative environmental ...

In the present paper, a new system of purpose built landfill (PBLF) has been proposed for the control of methane emissions from municipal solid waste (MSW), by considering all favourable conditions for improved methane generation in tropical climates. Based on certain theoretical considerations multivariate functional models (MFMs) are developed to estimate methane mitigation and energy generat...

A pilot study was conducted to assess the feasibility of composting of source separated organic matter of municipal solid waste (MSW) generated in low, middle and high income areas of Karachi city with a population over 14 million. Results of MSW analysis indicate the presence of high percentage of biodegradable organic matter (71-74%), acceptable moisture content (40-50%) and C/N ratio (38-40:...

Waste management is an important issue to solve as the assimilative capacity of the biosphere becomes overloaded by human needs and activities. According to European guidelines, reduction of waste generation and recovery of energy and materials are strongly recommended for environmentally sound waste management. In order to adopt a long-term sustainable strategy, it is necessary to assess the v...

The Municipal Solid Waste (MSW) management is a complex service that should be provided with suitable and feasible technologies in developing countries like India. The collection element plays a vital role in the MSW management. Hence, the planning and design of community bins make a greater impact on the environment. In this regard, an application model called Design of Community Storage Syste...
