Today's road and railway tunnels are normally covered by concrete in the lining and portal. If the excavated rock was to be utilized as concrete aggregate it would be beneficial both economically and environmentally. It could be more value generating compared to using the excavated rock as landfill or filling up old [[quarries]]. Additionally, the need to transport could be significantly reduced as the utilization of the rock could be placed outside the tunnel portal with a processing facility and a concrete bathing plant. The investment cost of this facility would be repaid as the project could potentially be self-supplied on concrete.<ref>https://brage.bibsys.no/xmlui/handle/11250/2454109</ref> |

Tunnel rock recycling or utilization is a method to utilize the rock excavated from tunneling into other needed areas besides as a landfill. Concrete contains 50-80% aggregates from sand and gravel and could potentially benefit from using aggregates produced from excavated tunnel rock.

If the excavated rock was to be utilized as concrete aggregate it would be beneficial both economically and environmentally. It could be more value generating compared to using the excavated rock as landfill or filling up old quarries. Additionally, the need to transport could be significantly reduced as the utilization of the rock could be placed outside the tunnel portal with a processing facility and a concrete bathing plant.
