Caraga (which is comprised of the provinces of Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur, and Dinagat Islands) is set to take the lead in advancing green mining technologies in the Philippines, with the Department of Science and Technology (DOST) rolling out new research, facilities, and partnerships in the region, according to DOST Caraga Regional Director Engr. Noel M. Ajoc.
Speaking at the Philippine Mining Club Luncheon on September 26 in Bonifacio Global City, Ajoc said Caraga is becoming the hub for sustainable mining initiatives, backed by pilot plants, mineral processing laboratories, and collaborations with both local universities and international partners.
“Caraga is where much of the country’s mineral wealth is located, and it is also where we are building the science and technology base to make mining more sustainable,” Ajoc said.
He outlined how DOST is developing and supporting technologies such as in-situ recovery and bioleaching, which minimize land disruption. Another innovation is waste valorization methods that turn mine tailings into usable products. Enhanced rock weathering is also being studied for its potential to capture carbon and support agriculture, while digital tools like artificial intelligence are being applied to exploration and resource efficiency.
Ajoc highlighted Caraga’s role in hosting key DOST facilities, including flotation pilot plants and assay labs, which underpin projects on nickel-pig-iron, chromite, rare earth elements, and advanced copper processing. These facilities are designed to help the mining industry adopt cleaner, more efficient practices.
Community development is also part of the strategy. Ajoc said DOST has signed agreements with 18 mining companies in Caraga to integrate science-based livelihood projects into their Sustainable Development Management Programs (SDMPs). These include initiatives like silkworm production for textiles and the introduction of new food product enterprises to diversify local economies.
He called on the mining sector to work closely with DOST in scaling up these innovations: “We hope also that you will work with us in ensuring that the talent of the close to 120 million Filipinos will be utilized to pursue green mining and have a sustainable and very competitive mining industry in the country.”
Can Caraga’s model of science-driven, community-linked innovation become the blueprint for sustainable mining across the Philippines?
