Use of Permeable Reactive Barriers for Landfill Leachate Management

Huge quantities of Industrial by-products are being generated every year and results in major environmental hazards worldwide. The present recycling techniques of the industrial by-products may only consume a very small amount of the unwanted scrap. The percentage of industrial by-products recycled is not compatible with the growth of unwanted scrap. A large number of industrial by-products are landfilled, stockpiled and illegally dumped. In order to avoid the continual addition of industrial by-products to these unsightly and unhealthy stockpiles, innovative methods of recycling and reuse of industrial by-products needs to be developed. The present study is an effort to explore the potential benefit of utilizing Industrial by-products as prospective substitute medium to gravel in the leachate collection system drainage layer which worked as permeable reactive barriers for leachate treatment and serve as reference study for the implementation of the most appropriate method for leachate management.
