efficiency rates at 97.5%. This means that over 97% of raw materials used on-site are converted to products and co-products that are used or recycled.15 • Slag is the main steelmaking co-product; it is primarily used in cement production, reducing CO 2 emissions by around 50%.16 It can also be used in roads (substituting aggregates),
An additional impact of raw materials production is contribution to the dispersion or dissipation of natural, non-renewable resources (such as minerals or fossil fuels). Environmental impacts associated with mining and the production of biotic materials (pulp, …
Aug 24, 2020· In this pipe manufacturing process, the raw material is used for the inner and outer layers and makes up 20% of the pipe, and the remaining 80% in between the two layers is made using the low-cost raw material. This significantly reduces the overall pipe production cost compared to pipes made with purely raw materials.
