Solution - Fly Ash Dump Site Restoration
Mining Area & Thermal Power Plant Fly Ash Dump Site Restoration through Sustainable Bio Energy Crop Plantation
Introduction
One of the biggest challenges in mining area is how to deal with the huge quantity of residues generated in mining operations. mining activities were generating large volumes of toxic and harmful residues for long periods of time and more over un-utilization of open mining area and thermal power plant coal fly ash dumpsites
The thermal power plant Pulverized fuel ash (PFA) or Fly Ash is generated from the combustion of coal is also a main cause of environmental pollution in soil, water and air. The prevalent practice of disposal is as dry ash / slurry of ash and waste water to open lands or ash ponds located near power plants and this has lain to waste thousands of hectares of land all over the world.
Thus, it is important to apply a sustainable restoration methodology for mining area and thermal power plant fly ash dump site through bio-remediation techniques to stabilize and effective utilization land reclamation & bioenergy crop plantation for productive plantation management & biomass feedstock to substitute coal (White Coal) to reduce the carbon emission & impact of Global Warming.
Biotechnological Intervention for Mining Area & Fly Ash Dump Site Restoration
The mining area & Fly Ash dump site area can be restored by the application of Jute Geo textiles, Biomass substrates, Beneficial Microbes and sustainable plants (Vetiver & energy crops) directly on fly ash through Bio-engineering techniques without using soil.
The geotextiles and biomass substrates act as a host for the beneficial microbial consortium to remediate the degraded land and support the rapid growth of energy grass (Miscanthus giganteus) plants to enhance the greenery development and phyto-stabilization.
The beneficial microbial consortium supports the bio-remediation of contaminated site with organic compounds soils provide an incalculable number of ecological niches for the growth of sustainable Bio-energy crops which play a decisive role in natural process to create rapid restoration and self-sustaining ecosystems.
