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 between 75-90%, with zero energy costs or sometimes even surpluses. The most advanced countries are Poland, Germany and the UK.
In 2019 we co-processed 3 million tons of waste in 90% of our cement plants. CEMEX has actually become a “waste eater”, consuming 32 times more waste than we sent for disposal in 2019. The non-recyclable by-products that we utilized from other sectors amounted to more than 13 million tons for the year, equivalent to the waste close to 50 million people generate a year.
