What unique ability do some plants used in bioenergy have to restore degraded lands?

They can extract heavy metals from the soil

Some plants used in bioenergy production have an amazing ability for phytoremediation, meaning they can extract contaminants, such as heavy metals, from the soil. This feature not only allows for the production of renewable energy but also for the restoration of lands otherwise considered unsuitable for agriculture or other uses. Thus, bioenergy can play a crucial dual role in environmental protection and the rehabilitation of degraded ecosystems.
