Chile: Cbb Cementos and Ambipar Environment have announced an upgrade to the Curicó plant that will allow it to process refuse-derived fuel (RDF). The US$5m investment will allow the unit to process around 36,000t/yr of RDF. The work will include building a reception hopper, a screening system, a belt feed belt to the calciner and a dosing system. Three warehouses will also be constructed. The alternative fuels upgrade is expected to start operation in early 2024.
