This represents an unprecedented step forward in the Spanish mining sector, further strengthening both companies\u2019 commitment to industrial innovation, efficiency, and the circular economy.<\/p>\n<p>The initiative involves the progressive incorporation of fly ash generated from biomass processes as a cementitious material in the production of paste used to fill underground chambers and galleries. These ashes, previously considered waste, have now been officially classified as a by-product by the Andalusian Regional Ministry for Sustainability, Environment and Blue Economy, allowing for their specific use in two of Sandfire MATSA\u2019s mines: Aguas Te\u00f1idas and Magdalena, located in Almonaster la Real.<\/p>\n<p><strong>Collaborative Work<\/strong><\/p>\n<p>The detailed process has received technical endorsement from the University of Huelva and has also been validated by LOEMCO (Official Laboratory for Construction Materials Testing) following five years of collaborative work between Sandfire MATSA and the Sustainability and Circular Economy division of Magnon Green Energy.<\/p>\n<p>In this regard, Andr\u00e9s Castilla, Head of the Backfill Department at Sandfire MATSA, explains:<\/p>\n<p>\u201cThis solution turns waste into a resource, reduces emissions, optimises processes, and strengthens our ties with the region. This project allows us to continue progressing towards more sustainable, responsible, and environmentally respectful mining.\u201d<\/p>\n<p>Meanwhile, Paloma Lastra, Director of QHSE and Sustainability at Magnon Green Energy, highlights:<\/p>\n<p>\u201cThis initiative exemplifies our commitment to the circular economy, which is an essential part of Magnon\u2019s DNA. It actively contributes to reducing the environmental footprint and promotes local development.\u201d<\/p>\n<p>In this way, Sandfire MATSA and Magnon Green Energy are leading an unprecedented initiative from Huelva, transforming a waste product into a by-product and giving it a new lease of life as a raw material in another production process.<\/p>\n<p><strong>Improved Strength and Durability<\/strong><\/p>\n<p>Tests carried out by the Sandfire MATSA team and verified in both national and international laboratories (including LOEMCO, Elabora, and CEMOSA) demonstrate that the paste resulting from the mix of cement and biomass fly ash maintains\u2014and in some cases improves\u2014its strength and durability, thereby enhancing its long-term performance and safety.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is the first by-product authorisation granted by the Regional Government of Andalusia.
