Industrial pollution has remained as one of the most daunting challenges for many regions around the world. Characterizing the determinants of industrial pollution should provide important management implications. Unfortunately, due to the absence of high-quality data, rather few studies have systematically examined the locational determinants using a geographical approach. This paper aimed to ...
This paper describes a methodology for estimating the true internal costs of construction waste, aimed at promoting environmentally friendly waste management. The study employs cost-benefit analysis, contribution margin analysis, the polluter-pays principle and a mathematical model: the model for Efficient Use of Resources for Optimal Production Economy (EUROPE), which has been introduced previ...
Waste heat to power (WHP) is the process of capturing heat discarded by an existing industrial process and using that heat to generate power (see Figure 1). Energyintensive industrial processes—such as those occurring at refineries, steel mills, glass furnaces, and cement kilns—all release hot exhaust gases and waste streams that can be harnessed with wellestablished technologies to generate el...
Hazardous substances, such as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) also have been detected in Municipal Solid Waste (MSW) and industrial waste incinerators in Korea. In this study, we estimated the exposure status of these hazardous substances and their heath effects in workers and residents near the MSW incinerators and residents near the industri...
locating landfills in urban areas is one of the most important issues in urban planning because of the effect on economy, ecology, and environment, therefore the right management and principled landfilling of solid waste is the major concern all over the world especially in the developed countries. in locating landfills, different criteria should be considered. in the present study, locating si...
to find the quantity and quality of wastewaters of the two main industrial units of khoy city in west azerbaijan province, iran, namely the slaughterhouse and the totia chocolate factory, ten composite samples were taken in 112 hour intervals between 3.5 and 7.5 a.m. (4 hours working shift) from the slaughterhouse and between 7.5 a.m. and 2 p.m from the totia chocolate factory (8hours working s...
biological removal of lead was observed in this study during treatment of synthetic solutions of this heavy metal by a sample of waste activated sludge (was) having mlss concentration of 10000 mg/l. the objective was determining the capability of was in removal of lead in three different conditions of treatment: without any aeration and feeding, by simultaneous aeration and feeding and by aerat...
The 3M Company incinerates chemical wastes from manufacturing operations in a 23 M kcal/hr (90 MM Btu/hr) rotary kiln incinerator which has air pollution control equipment. This paper deals with the essential features which have resulted in this successful incineration operation for industrial wastes. These features include waste materials handling considerations, design aspects, and main tena...
Supercritical fluid extraction of all-E-lycopene from tomato industrial wastes (mixture of skins and seeds) was carried out in a semi-continuous flow apparatus using ethane as supercritical solvent. The effect of pressure, temperature, feed particle size, solvent superficial velocity and matrix initial composition was evaluated. Moreover, the yield of the extraction was compared with that obtai...
Use of vitrified urban incinerator waste as raw material for production of sintered glass - ceramics
The crystallisation behaviour of vitrified industrial waste (fly ash from domiciliary solid waste incineration) was examined by differential thermal analysis, X-ray diffractometry and scanning electron microscopy. It was demonstrated that powder processing route was required to transform the vitrified industrial waste into glass-ceramics products. Time-Temperature-Transformation (TTT) diagrams ...
