prepol® SC – step combustor for waste utilization in cement plants

The prepol® SC is an add-on for the prepol® precalciner. On this simple combustion grate, waste can burn for more than 1,000 seconds at high temperatures. Compared to ordinary calciner technology with only up to 7 seconds residence time the prepol® SC opens a new dimension in burning: It provides a high flexibility for a wide variety of wastes that leads to a new level of fuel-cost savings – and paves the way for a more sustainable cement production.

Waste management in cement industry – the path to alternative fuels

In 2025, according to UN figures, more than 8.1 billion people will live on the earth. The cement industry can be a huge leaver for a greener future and to manage upcoming waste challenges regarding resources and waste management: Through the use of the prepol® SC coal, gas and oil as primary energy sources can be replaced 100 percent by alternative fuels. This contributes clearly to our vision of the green polysius® cement plant. We are convinced that this is a transformation journey - from #grey2green.
