Technological Upgrade in Colombia
Holcim Colombia and Geocycle have modernized and expanded their co-processing platform in Nobsa, Boyacá.
This technological upgrade, backed by a two-million-dollar investment, would enable the transformation of more than 100,000 tons of waste per year into a sustainable energy source. The alternative fuels are derived from waste materials such as paper, cardboard, plastics, and biomass that would otherwise end up in landfills. The system upgrade includes the installation of a state-of-the-art shredder with a nominal capacity of over ten tons of waste per hour, along with new transfer systems and a modern dosing system capable of feeding up to 20 tons of alternative fuels per hour into the cement kiln. “These enhancements will gradually increase the thermal substitution rate of fossil fuels used at the Nobsa cement plant – from 40 percent in the short term to an ambitious target of more than 70 percent by 2030,” Holcim informed.
