BACKGROUND In all, 70 municipal incinerators, 307 hospital incinerators and 460 toxic-waste landfill sites in Great Britain were examined for evidence of effluents causing childhood cancers. Municipal incinerators had previously shown significant excesses of adult cancers within 7.5 and 3.0 km. The relative risks for adults had been marginal and an analysis of childhood cancers seemed to offer ...
E-waste refers to both electronic and electrical waste materials; namely any items which rely on an electric current or electromagnetic fields in order to operate, and contain a hard-drive or significant electronic components and/or a printed circuit board. E-waste is outstripping the general growth of the municipal waste stream. Increasingly, smaller and cheaper electronic items are being disp...
The management of municipal solid waste (MSW) in China is facing urgent problems with rapid industrialization and urbanization. This article focused on the status of Hangzhou, capital city of Zhejiang province, China. The regulations, policies, implementation, barriers and solutions about source separation, separate collection, clean & direct transportation, treatment and disposal were introduc...
Some contaminants emitted by municipal waste incinerators are believed to adversely affect reproductive health in the exposed populations; yet only limited and conflicting epidemiologic evidence on this issue has been provided so far. In this study we analyzed rates of spontaneous abortion and prevalence at birth of congenital anomalies in women residing or working near the municipal solid wast...
Background and Objective: In recent years, management and disposal of municipal solid waste has become a global problem and the most important environmental concern. Anaerobic digestion is a cost-effective solution for treatment of both solid waste and wastewater. The aim of this study was to investigate the positive or negative effects of calcium chloride content in anaerobic digestion process...
Organic wastes under consideration are of natural origin that possess biochemical characteristics ensuring rapid microbial decomposition at relatively normal operating conditions. When considering the organic waste treatment we have generally in mind organic mineralization, biological stabilisation and detoxification of pollutants. Most common organic wastes contain compounds that are mainly we...
Abstact: The aim of the research project was to carry out the co-digestion of organic fraction of solid municipal waste in the form of source separated kitchen waste and sewage sludge. The influence of the kitchen waste as a co-substrate on the stability and efficiency of the process was determined. Mesophilic fermentation (36 ̊C) was conducted for sewage sludge as well as mixtures of sewage slu...
Introduction: The best way to recycle municipal wastes is to separate them at home by the users. To this end, participation and cooperation of all citizens is required and the necessary infrastructure should be provided in the field of waste segregation. This study was conducted to determine the status of citizenschr('39') participation in separating urban wastes from the source and to investig...
