Cenospheres

The problem:

A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. On average 0.5% of the fly ash generated in a coal fired power station boiler are Cenospheres.

When fly ash is wet discharged in to ash ponds/lagoons cenospheres float on the water surface, get finally air borne and cause dust pollution.

 
The solution:

The floaters are collected from the water surface, dried and graded by screening into particle sizes between 150 to 300 micron.

The end-product is used as a filler in compounds and paints as well as a component in oilwell cement.

Accolades

The Intergovernmental Panel on Climate Change (IPCC), India, became the Nobel Peace Prize laureate together with the former American Vice President Al Gore for laying foundations for the measures that are needed to counteract climate changes. This panel in collaboration with TERI (Tata Energy and Resources Institute) issued in 2006 a book containing 25 best projects for corporate environmental responsibility in India - the DIRK Pozzocrete plant at Nashik was selected as one of those twenty five project.
