Urbanization and rapid growth of population in India has led to drastic increase in municipal solid waste. Unscientific disposal of municipal solid waste is one of the main reasons attributed for environmental degradation. The present work concentrates on municipal solid waste management in Tiruchirappalli City which comprises of four zones namely Srirangam, Goldenrock, Araiyamangalam and Abish...

Because human societies have not closed solid waste loops in the production and consumption of gaDds,methods of solid waste treatment are still necessary. In this work the author examines two modem methods of municipal solid waste (MSW) treatment as employed in Sweden. These methods are waste treatment in a bioreactor cell and MSW incineration. The investigation analyzes the critical economic c...

This paper deals with the study of radioactive waste generation and their treatment techniques. The wastes that are generated during the front and back end of the nuclear power production are classified are low, intermediate and high level waste. The various existing process for the treatment for the waste like, reprocessing, pyroprocessing, transmutation, and options available for the disposal...

As a clean energy source and industrial material, hydrogen is very valuable. Electrolysis of water and chemical methods are well-known for producing hydrogen, however, all of these methods need additional energy supply. Besides highly energy cost, the chemical methods will lead to serious environment pollution. Compared with traditional methods, biological production of hydrogen has showed sign...

Background: Laboratory wastes are one of the environmental issues of developing countries and cause diseases and epidemics. Laboratory waste management is planned with the aim of preventing unfavorable effects on human health and the environment. The aim of the present study was to determine the status of medical waste management in clinical laboratories affiliated with Rafsanjan University of ...

The biological treatment processes found wide applications in wastewater, air & solid waste pollution control. The need for alternate cost effective treatment technologies led to similar biological treatment processes for waste gas streams. One such treatment technology is biofiltration. Biofiltration technology utilizes the microorganisms to biologically degrade Volatile Organic Compounds (VOC...

Solid Waste management (SWM) is an acute and complex problem in developing economies like India. Progressing states have inadequate budget for waste management, out of which major portion of which goes to collection and transportation rather than its treatment. Various techniques like land filling, incineration and composting have been used for waste management, but none of them fully assure th...

On behalf of the International Solid Waste and Public Cleansing Association (lSWA), it is a pleasure to open this First Annual North American Waste-to-Energy Conference. Solid waste management has moved to the forefront of the environmental agenda. The level of activity and concern by citizens and governments worldwide has reached unprecedented levels. Nations are considering restrictions on pa...

In this study, waste edible oil was prepared by both heat and aeration treatment, and the increasing inhibitive effect of tocopherol treatment on the acid value (AV) and carbonyl value (CV) of the oil was investigated. The AV and CV of waste edible oil treated with tocopherol were 0.1-1.0% lower than those of the nontreated oil, indicating that tocopherol exerted a radical-scavenging activity. ...

A team of Purdue University engineers and scientists has been involved in studying sources, translocation mechanisms, and fate of cadmium in the environment. One of the principal results of this work has been the development of a cadmium flow model for the U. S. which involves simulating sources, use patterns, waste treatment and recovery techniques, waste disposal options, and environmental fl...
