Waste Disposal and Recycling in Steel Industry

Recycling is a process using materials (waste) into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production. Recycling is a key …

Tailings - Earthworks

Tailings dams are built gradually over time, as the mine produces more waste and hydro dams are constructed all at once. This means that safety oversight can change significantly if the mine changes operators, if the type of ore changes as the mine reaches deeper deposits, or if the mining company comes under economic pressure. For example, the Mt. Polley dam was intended to be a centerline dam but was modified during operation to use deposited tailings …
