Planting of landfills with trees and their irrigation with landfill leachate appears to be a sustainable way of their remediation. Growth of poplars, watered with landfill leachate, has been compared with control, watered with standard nutrients. The achieved water use and biomass of plants watered with leachate was similar to plants watered with standard nutrients. This shows on big potential for the application of phytoremediation by trees for the treatment of leachate, as well as on the use of leachate as a substitute for plant nutrients at the biomass production for energy purposes.

A pot experiment is described with a fast-growing poplar clone and two native willows, irrigated with landfill leachate and compost wastewater over a one year growing period. The use of leachate resulted in increased and the use of compost wastewater resulted in reduced aboveground biomass compared to control water treatments. Populus was the most effective in biomass production, whereas S. purpurea was the least effective, but less sensitive to high ionic strength of the irrigation water compared to S. viminalis.

The contents of micro and macro elements in wastewaters are not necessarily in ideal proportion for the plant growth. We can be confronted with high concentrations of mineral substances affecting soil salinity. A pot experiment has been performed with willows and poplars planted in substrate irrigated with different concentrations of leachate or compost water. The paper presents the effects of application of landfill leachate from municipal landfill site and wastewater from the production of compost on modification of soil salinity and capacity for water reception.

The use of renewable energy sources has lately been increasingly put forward. The important role among them play energy plants and woody biomass. Providing sufficient plant nutrients for their optimal growth is here of essential importance. Their substitution with waste sources could be a promising option for the reduction of production costs. The article speaks on sustainable approaches toward rehabilitation of degraded environment and simultaneous possibilities of production of RES with closed mass flow, where a waste from one side represents a nutrient source on the other side.

The article summarises the principal soil pollution sources and introduces the possibilities of their solutions with ecoremediations, which comprise natural mechanisms like phytoremediation, bioremediation and other self-cleaning processes running in the environment. The use of woody plants for the remediation of polluted soil is presented, the ways of remediation of sludge from wastewater treatment plants and co-natural remediation of landfill sites. The advantages and limitations of ecoremediational approaches are compared with classical physical and chemical treatment processes.
