Pollution is a permanent global dilemma and our environment is continuously being polluted by metals and organic contaminants. The cost of current engineering technologies, used so far to clear environmental contaminants, is billions of dollars. Conventional physicochemical treatments of soil have stimulated the development of new remediation technologies i.e. Phytoremediation, a plant based technique. Plants can extract heavy metals from soil by making complexes with metals and their own metabolites by a process of chelation. Despite this era of omics, the improvement in the technology can be carried out by exploring the new candidate plants and their key players (gene, proteins and enzymes, metabolites) involved in hyper-accumulation. There is a dire need to improve and use this technology as a tool of bioremediation for sustainable economy and to save our earth. This article is designed to probe the potential improvements in the research and development activities relating to different aspects of phytoremediation
