CEMEX has more than 20 years of experience in co-processing waste in our plants. Today, the most successful plants operate at alternative fuels substitution rates over 70%, with zero energy costs or sometimes even surpluses. Our installations with the highest alternative fuels rate include Chelm and Rudniki in Poland, and Prachovice in the Czech Republic.
In 2020 we co-processed almost 3 million tons of waste in 91% of our cement plants. CEMEX has actually become a “waste eater”, consuming 31 times more waste than we sent for disposal in 2020. The non-recyclable by-products that we utilized from other sectors amounted to more than 12 million tons for the year.
