Environmental decontamination is an integral part of bioeconomy and sustainable development.

In recent years there has been growing interest in using plants for environmental decontamination. On the other hand the volume of contaminated substrates (water, soil and air) is increasing due to anthropogenic and technogenic sources of organic and inorganic contaminants.

Metals are the most prevalent inorganic pollutants/ contaminants and are widely used for a wide variety of needs starting with building materials to information technology. Therefore, the bioavailable fraction of metals is increasing.  Today’s global economic growth, extensive industrialization and extraction of natural resources have resulted in environmental contamination and pollution. Large amounts of toxic waste have been dispersed in thousands of contaminated sites spread all over the globe.


The challenge is to develop innovative and cost-effective solutions to decontaminate polluted environments. Bioremediation is emerging as an invaluable tool for environmental cleanup. Various strategies are being applied to reduce the accumulation of toxic metals in plants. Cultivation of edible crops in contaminated soils is a subject of human health concern if metal concentration in the edible parts of crops plant exceeds the permissible level. In such cases non-food crop production viz. value chain and value additions appears profitable. The movement in this field is towards production of diverse biofuels (solid, liquid and gaseous).  Essentially the crux is revolving around bioenergy and use of bioresources harvested from environmental perturbed/stressed agro-ecosystems. Although bioremediation contractors must profit from this activity, the primary driver is regulatory compliance rather than manufacturing profit.
