The aim of this research was to add the earthworms into the constructed wetlands, both in Germany and Thailand, in order to investigate whether they could improve the treatment performances. For Germany, earthworm-assisted constructed wetlands exhibited better treatment efficiency than conventional vertical subsurface-flow constructed wetlands and the unplanted constructed wetlands with earthworms. For Thailand, the production of sludge on the surface of wetlands was reduced by 40% with earthworms. Apart from that, alternative plants with high resource recovery potential were proposed. The recommendation table was developed with 13 suitable species. There are more than one “most appropriate species” in each climatic region.
