METHODOLOGY FOR SLAG LCI CALCULATION worldsteel

The steel industry has developed a methodology to calculate the life cycle inventory (LCI) for the slags from the steelmaking processes. It can also be used in LCA studies where the worldsteel approach to dealing with the industry co-products of system expansion is not allowed.

Life Cycle Assessment of Internal Recycling Options of

Jul 01, 2011 The internal recycling process of BOF slag which is one of the huge solid wastes from iron and steel industry was emphasized. Based on the four scenarios of different internal recycling strategies for BOF slag, life cycle assessment (LCA) as a valuable tool for industrial solid waste management was applied to analyze the contribution to reducing environmental impacts and resources burdens for

Options for managing alkaline steel slag leachate: A life

Nov 20, 2018 1. Introduction. Steel slags are a high volume by-product of steel production with annual global production of about 170–250 million metric tonnes/year ().Long-established routes for re-use and recycling of steel slag exist, predominantly as fill material or road ballast in construction applications (Motz and Geiseler, 2001).In Europe, between 70 and 80% of steel slag is currently reused

Cubic Yards To Tons Calculator

Convert your density to lb/yd 3. 85 lb/ft 3 = 2295 lb/yd 3 (1 pound per cubic foot equals 27 pounds per cubic yard) If you're in the US, divide 2295 by 2000 (there are 2000lb in a US ton). If you're in the UK, divide by 2200 (there are 2204.62 lb in a metric tonne) You now have your answer in tons per cubic yard (1.15 US tons or 1.04 metric tonnes)
