India: Heidelberg Materials subsidiary Zuari Cement has commissioned a 20t/hr alternative fuel (AF) production line at its 7.1Mt/yr Yerraguntla cement plant. The line includes an UNTHA XR3000C shredder. This will support continuous operations and turn waste to AF in a single step, according to Zuari Cement.
HeidelbergCement India technical director Vimal Jain said “We are passionate about driving environmental progress throughout our business, and the use of AF is one way to do that. But this waste-to-energy feedstock comes at a cost, which is why co-processing makes so much sense. When designing this plant, we needed to ensure versatility to allow for changing market conditions, and an investment in technology that makes commercial sense and is built to last.”
Saudi Arabia: City Cement has announced that its waste management subsidiary Green Solutions for Environmental Services (GSES) has launched a new company to produce alternative fuel (AF) for local and overseas markets. The company is a joint venture in which GSES holds a 29% stake, with the majority stake held by Public Investment Fund subsidiary Tadweer Environmental Services. The joint venture has US$1.8m-worth of capital.

Cemex Mexico’s Huichapan cement plant in Hidalgo set the company record for the year, with 207,000t of AF co-processed in its cement production.
