The abysmal state of and challenges in municipal solid waste management (MSWM) in urban India is the motivation of the present study. Urbanization contributes enhanced municipal solid waste (MSW) generation and unscientific handling of MSW degrades the urban environment and causes health hazards. In this paper, an attempt is made to evaluate the major parameters of MSWM, in addition to a compre...

In this study, an integrated fuzzy-stochastic linear programming model is developed and applied to municipal solid waste management. Methods of chance-constrained programming and fuzzy linear programming are incorporated within a general interval-parameter mixedinteger linear programming framework. It improves upon the existing optimization methods with advantages in uncertainty reflection, dat...

The management of municipal solid waste is one of the major problems of the present world. The use of microbial enzymes for sustainable management of the solid waste is the need of the time. In the present study, we have isolated a potent amylase producing strain (ISL B5) from municipal solid waste. The strain was identified as Pseudomonas stutzeri (P. stutzeri) both biochemically and by 16S rD...

The biodegradation module of a simulation program for municipal solid waste landfills (MODUELO) was developed. The biodegradation module carries out the balance of organic material starting with the results of the hydrologic simulation and the waste composition. It simulates the biologic reactions of hydrolysis of solids and the gasification of the dissolved biodegradable material. The results ...

The incineration of municipal waste has been the subject of controversy for many years and has been widely opposed because of concerns about the pollution of the air with toxic materials, particularly dioxins. Many incinerators have had to stop operation and many projects have been abandoned. At the same time, communities continue to be faced with the challenge of handling growing amounts of wa...

Hong Kong is also paying an environmental price. Food waste, accounting for about 40% of municipal solid waste, accelerates the depletion of the limited landfill space. Two of the three strategic landfills in Hong Kong have already reached capacity respectively in 2014 and 2016, while the remaining one is expected to be exhausted in 2018. The greenhouse gases generated by food waste are imposin...

Improper solid waste management is causing negative impacts in Pakistan. To investigate the causes Rawalpindi city was selected as a case study. The situation is becoming very complex in the city due to industrialization, urbanization and improved living standards of urban areas, as these things are the cause of drastic increase in the quantity and complexity of generated waste. From this resea...

Plasma pyrolysis integrates thermo-chemical properties of plasma using pyrolysis process for safe disposal of solid wastes. It is an environment friendly technology to generate valuable byproducts by converting municipal solid waste, biomedical waste and hazardous wastes at 800-1000°C. Plasma Pyrolysis of plastic wastes generates pyrolysis gas, which can be utilized for energy recovery via diff...

In today’s world we are living in an age where disposables have become a way of life. In this “use and throw” society, plastics have become a part of our day to-day lifestyle, and affect everyone. Plastics have several drawbacks, and also contain toxins that can trigger the development of cancerous diseases. The hospital today is on the brink of a progressing ecological catastrophe. Excessive u...

This presentation discusses the ecological optimisation of municipal waste management (WM) systems. The purpose is to help local decision-makers in designing the integrated waste management solutions that are optimal from the ecological point of view. The study uses the life cycle methodology (LCA) for building a model and testing different waste management scenarios in order to see whether the...
