A liquid housing container recycling method is provided for a liquid housing container with a liquid housing body that includes a liquid housing unit that is configured to house liquid, a supply member with a supply port that is configured to be connected to a liquid supply tube of a liquid consuming device, and a filter through which the liquid is configured to pass, with the liquid inside the liquid housing unit being supplied to the liquid consuming device by, after passing through the filter, flowing to the supply port along a supply flow path of the supply member. The liquid housing container recycling method includes forming a detour flow path in the liquid housing body such that the liquid inside the liquid housing unit flows to the supply port without passing through the filter in the detour flow path, and injecting the liquid inside the liquid housing unit.
