Hundreds of millions of tons of earth and rock are excavated for tunnels each year — transforming waste materials into construction aggregates right on the construction site.
ProtectGD is interested because of the enormous volume of tunnel excavation from metro, road tunnel, and underground infrastructure projects — which must be transported away for burial at very high costs.

Tunnel excavation rock and soil are often viewed as costs (transportation, disposal) rather than resources. ProtectGD transforms tunnel muck and TBM spoil—including the difficult-to-handle fine-grained particles—into aggregates, backfill materials, and prefabricated components right at the construction site, helping investors reduce transportation and disposal costs.
Reducing transportation and backfilling costs for excavated soil—one of the biggest expenses in underground infrastructure projects—and utilizing materials on-site helps shorten timelines.
Reducing pressure on landfills and urban land, decreasing carbon emissions from long-distance transportation, and closing the material recycling cycle right at the project site.
Our mission is to build the next generation of sustainable building materials industry platforms — where business models create economic value while restoring the environment, contributing to achieving the Net Zero goals committed at COP26.
