Applicability of Agricultural Wastes for Heavy Metals Bio Remediation- A Low-Cost Approach

Abstract

Heavy metals are toxic recalcitrant compounds, present in many industrial effluents like tannery industry, electroplating industry and more. Industrial sector develops whole world and contributes to welfare of the country and supports every country gross domestic product (GDP). To protect our environment from toxic compounds and carcinogenic heavy metals without compromising on environmental health, new eco-friendly adsorbents must be implicated in treatment of industrial discharges. The agriculture wastes from both domestic and large-scale sectors majorly dumped in landfills, which further pollutes the environment, so these agriculture waste can be further utilized for its metal sequestration property and can be used for heavy metals bio-remediation. This study shows that agriculture waste such as saw dust, brans, cobs, pulps, fruits flowers, adsorbed up to 98 % of the heavy metals. This study supports sustainable development goals and recommends using agriculture wastes, an eco-friendly green technology, for safeguarding our environment from further secondary pollution.
