Bioremediation is an eco-friendly and sustainable approach to mitigate pollutants from soil. Especially, Plant assisted bioremediation or phytoremediation has a great potential to stabilize or degrade the pollutants in the soil. At the moment, growing aromatic, medicinal, and energy plants for the use in phytoremediation of heavy metal-contaminated sites is getting a lot of attention. These plants have a distinct regulatory system that functions synergistically to combat stress and allows them to adapt in contaminated soils. However, they have also a wide application in various industries such as cosmetic, pharmaceutical, perfumery, etc. and the biomass can be profitably valorized for energy production in accordance with a circular economy, which ultimately promotes the bioeconomy. This chapter covers two case studies. In the first one, a large integrated sponge iron waste with steep slope was stabilized by blanketing with topsoil and coir-mat, seeded with grass-legume mixture (Cymbopogon citratus, Stylosanthes hamata, and Sesbania sesban) and in the second, uses of Cistus ladanifer plant as a potential candidate for bioremediation and bioeconomy have been discussed. These studies showed that phytoremediation can be more techno-economically acceptable technology which can have a great economic return in line with circular economy model.
