Plant-dyed ice is produced by extracting plant pigments from wood flour, leaves, and flowers, followed by special processing and freezing to form colored ice blocks.

When spring arrives and temperature rises, the ice will melt, and the dyed ice will biodegrade naturally and blend into the ecosystem without leaving any pollution.
