The purpose of this research is to use helophytes as floating filters in an artificial aqautic system for water treatment in Lake Cheimaditida and irrigation channels (Western Macedonia, 40 km southeast of Florina, Greece) and in irrigation channels and pods (broader region of Avila, province 150 km east of Madrid, Spain). By using these floating filters, the challenge of producing feedstock for bioenergy without using agricultural land will be achieved. There are several factors that should be considered in order to have successful results such ascharacteristics of the water body and its surroundings,planting density and distribution, etc. Also, there are some criteria that one site must meet for being suitable for GFF establishment. Some of them are the protection of the environment, the environmental conditions for helophytes growth, conditions on the area, etc. Hopefully, the findings of this study may be useful for both bioenergy production with no land use and for contaminated water treatment.
