The Danieli Group has been concerned with the environmental issues related to the steel production cycle for more than 40 years. In keeping with an international commitment to encourage recycling, recovery and re-use of waste materials, and with a constant environmental awareness, Danieli Environment has developed new technological solutions enabling slag reutilization.

Another byproduct issue at the Polk plant deals with slag disposal. Although the slag is classified as non-hazardous, local regulations require disposal in a different class of landfill. Polk must use a Class I landfill that is double-lined with leachate extraction/control versus a much less expensive and more available Class III landfill.

Sep 29, 2014· The main waste materials in the BOF steel making are converter slag, scrap, waste refractories, converter muck, and gas cleaning plant (GCP) sludge. Except GCP sludge all other waste materials are usually generated in mixed condition which means that during generation one waste material gets contaminated with other waste material.

The recovered waste oil may be reused or at least sold for road oil, and the treated waste-water may be reused to satisfy plant process, cooling, or other non-potable water demands. Carried to the ultimate end, such reuse may virtually eliminate plant waste-water discharges, thereby negating the involvement with waste-water regulatory agencies.

Waste Utilisation in Sinter Plant Coal mine wastes, iron ore fines and by-products from the plant including Blast Furnace and LD Slag, all wastes have potential for value added applications. To recover these values and efficiently utilise the wastes, Tata Steel uses advanced technology.

The hazardous waste incinerator is the main equipment where converts hazardous materials into slag and flue gas. The rotary kiln is a cylindrical vessel, inclines slightly (2-3°) to the horizontal. We can use coal, oil, gas, and others as fuels to heat the incinerator to disinfect the hazardous waste under high temperatures.

Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide.A plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas, with slag remaining as a byproduct. It is used commercially as a form of waste .

K+S recycles salt slag from the secondary aluminum industry completely residue-free. By this we mean: completely, one hundred percent. Our specially developed REKAL® plant extracts the reusable aluminum from the slag. The process is rounded off by the separated substances potassium chloride, aluminum oxide and ammonium sulfate.
