plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. people’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. this study aims to determine community’s perception of usage and disposal of plastic bags in eastern ethiopia. a quantitative cross-sectional study has been condu...

Background & Aims of the Study: One of the most important pollutants in drinking water, air and soils is heavy metals. It is very harmful for humans and other live organisms. The purpose of this study was the usage of a co-composting process for removal of heavy metals from municipal solid waste and sewage sludge. Materials and Methods: This experimental study was a condu...

Not all heavy metals are toxic. Some at lower concentrations are essential to the physiological status of the organism. Under certain conditions, induced toxicity occurs when the heavy metals are in the form of cations which tends to bind to certain biomolecules, thus becoming toxic to organisms. In many industries, toxic heavy metals such as As, Cd, Cr, Cu, Hg, Pb and Zn, are released mainly i...

In view of fast paced economic growth accompanied with rapid urbanisation, management of municipal solid waste has emerged as one of the major environmental challenges of present times. Indian cities are often characterized by poorly rendered services including waste management-the most ignored of all basic services, on account of various reasons. The situation worsens with increasing populatio...

At present, the main contributors to waste to energy are municipal solid waste, manufacturing waste and landfill gas. Probably we are all most familiar with the first (MSW), which involves the garbage that the garbage men pick up regularly at our homes and which goes to a landfill, a transfer station, or incinerator. Today we are going to introduce you to something relatively new on the alterna...

Land application of contaminated waste products has been defended as beneficial use by some scientists and regulators, based on the premise that the behavior of any toxins accumulated in soils from this practice is reasonably well understood and will not have detrimental agronomic or environmental impacts into the foreseeable future. In this review, I use the case of toxic metals in sewage slud...

Disposing of sewage sludge in an economical and environmentally acceptable manner is a problem for all communities that have wastewater treatment plants , Similarly , many com­ munities are having to dispose of increasing quantities of solid waste. These problems could be solved by co-disposal of sludge and solid waste in a common facility. This study , .‘nvnH .. --­ au­ &LLnAE -' .‘maL­nH .. o...

Now a day, we are facing a problem regarding the management of waste generated daily. This waste includes solid waste from industrial zone, commercial zone and residential zone. Among all these waste management from residential zone requires first priority because if this waste is not properly disposed off daily, then it will create problems to public health, affects the aesthetics. This paper ...

introduction the problem of solid waste management is one of the most critical environmental issues because of rapid population and economic growth, urbanization, and industrialization. furthermore, global attitudes are bent on accessing sustainable agriculture and conserving a clean and green environment. vermicomposting is a process to convert organic waste by the use of earthworms to produce...
