India is using fly ash for land reclamation

 

Many Indian cities are facing shortage of land, and land reclamation from sea can give great success for these cities. A large quantity of fly ash has been permitted to reclaim the land from sea, basically in coastal urban cities. In 2003, the Government of India permitted the use of fly ash for reclamation of sea. Subject to the rules made under the Environment Protection Act (1986), reclamation of sea shall be a permissible method of utilization of fly ash. Land reclamation includes maintaining water and air quality, erosion and damage to land properties, minimizing flooding, wildlife and aquatic habitats caused by surface mining. Singapore and Dubai have conducted this type of sea reclamation in a large scale.

Three alternative ways have been investigated to utilize the waste in sea reclamation projects: (1) Singapore and Japan-based technology, (2) plasma gasification-based technology and (3) strengthened sediment-based land reclamation in a large scale.
