Bioremediation of Waste Dumping Sites

Abstract

Different methods have been followed to degrade the waste-contaminated materials, but the technique of bioremediation is more preferred. The biore-mediation of hydrocarbons, chlorinated compounds, aromatic hydrocarbons, toxic heavy metals (HMs), and plastic wastes have been observed at landfill sites. Most countries prefer landfilling as the leading method for the reduction and management of solid wastes. Since the landfill is the popular method of waste reduction and disposal, therefore proper monitoring and identification of hazards are necessary. The accumulation of plastic wastes in the landfill is an important component. Till now three different methods (recycling, incineration, and landfill) are adopted for proper management and disposal of plastic wastes. The bioremediation of plastic wastes and toxic metals in a landfill is limited as few secondary pollutants may be emitted into the environment. Although bioremediation is an attractive selection in landfill due to cost and sustainability towards the environment, yet it has many drawbacks; therefore, substantial research is still needed for effective bioremediation of all kinds of wastes available in landfills.
