steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

Industrial growth and environmental damages, as two important indicators in sustainable development are followed by steel industry. This article leads industries to green industry. In this case, energy, material, capital consumption and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally sui...

Primary metal production operates with large tonnages and takes advantage of economies scale. Metal recycled from low-value waste streams, competing in the same global market as primary production, will be more competitive by also taking up-scaling. However, an overview streams to see upscaling potential needs provided literature. In response, this study provides estimates copper, zinc, lead in...
