Remediation management for contaminated sites is presently a fundamental issue worldwide, which is highly important in the fields of practice, research, and policy at the national and international levels. The environmental remediation policy provides a nationally accepted program and position, and also sets visible evidence of the country’s aims and concerns. The national policy for contamination remediation should define the bigness and scale of the possible risk, as well as environmental concerns should be given high priority and financial provisions established for any remediation. Traditional strategies for contaminated site remediation mostly aim to decrease contamination levels at low cost and in a short period. Traditional approach may not be sustainable due to ignoring environmental side effects, thus there is an extensive requirement for “green” or “sustainable” approaches. Sustainable and Green Remediation (SGR) address economic, social, and environmental effects, and can conserve natural resources and protect soil, water, and air quality by decreasing emissions and other waste. Therefore, where possible and efficient, phytoremediation and bioremediation approaches may be chosen as basic remedial methods.
