Traditional technologies of solid fuels incineration account for higher level of pollutant in comparison with incineration of liquid and gas fuels. However the fraction of heat and electric power generated at coal fired thermal power plants will increase and by 2020 will have exceeded 50%. Plasma activation promotes more effective and environmental friendly power coals incineration [1]. Effecti...

Environmental assessment of municipal solid waste (MSW) management scenarios would help to select eco-friendly scenarios. In this study, the inventory data in support of life cycle assessment of different MSW are presented. The scenarios were defined as: anaerobic digestion (AD, Sc-0), landfilling combined with composting (Sc-1), incineration (Sc-2), incineration combined with composting (Sc-3)...

This study is a comparison of Swedish and Danish legislation on recycling of MSWI (Municipal Solid Waste Incineration) residues for construction purposes. The aim has been to look for differences and figure out whether these could be a reason for the minor use of MSWI ashes in Sweden compared to Denmark. To do this, text analysis has been performed on Swedish and Danish environmental legislatio...

Teeth are amongst the most resilient elements of the human skeleton and are thus often utilized in routine forensic investigation involving the identification of unknown remains. Teeth exposed to thermal stress have the potential to not only aid in identification, but also in understanding the circumstances surrounding the fire. Children are twice as likely to become victims of house fire becau...

Old agrochemical samples were analyzed for their dioxin impurities. Some herbicides were contaminated with 2,3,7,8-chlorine-substituted dioxin congeners. Using these new data as well as impurity and emission data reported in the literature, the time trends for dioxin emissions from the use of chlorinated aromatic compounds and some incineration activities have been estimated. The results indica...

Issues of hazardous waste management are major concerns in the countries of eastern and central Europe. A National Institute of Environmental Health Sciences-supported conference was held in Prague, Czech Republic, as a part of a continuing effort to provide information and promote discussion among the countries of eastern and central Europe on issues related to hazardous wastes. The focus was ...

Gas chromatography/mass spectrometry was used to analyze the pyrolytic byproducts from an Army-unique propellant compound (AA2) that is composed of predominantly nitrocellulose and nitroglycerin. Compounds produced by AA2 pyrolysis were compared to compounds detected in the gaseous effluent from AA2 incineration. The light permanent gases and most of the higher molecular weight byproducts produ...

Waste incineration still seems to be an essential technology in the concept of integrated waste management. However, the desirable quantity of waste incineration residue needs to be as low as possible. Therefore, related optimization of two-stage waste incineration technology has been performed with the main goal of producing lower amounts of boiler ash, fly ash and flue gas-treatment residue, ...

The proximate and ultimate analyses of 20 constitu­ ents of municipal and commercial refuse are presented, to .. gether with the calorific values. The analyses are useful o incinerator engineers as they are the basis for calcu­ Jating air requirements, flue .. gas volumes, and heat and material balances. The analyses of components of refuse permit the calculation of composite analyses of mixed ...
