Phytoremediation is more effective and economically valuable when:
The crops used produce high added-value biomass providing a revenue.
Two phytoremediation strategies are deployed in GOLD:
The possibility to combine phytoremediation with the production of biomass seems very promising since a double target may be achieved. The harvested biomass can be used as feedstock for bioenergy purposes while plants decontaminate the soil. In this way, marginal or degraded land that cannot be utilized for food production will be upgraded and recovered for agricultural use.
