Expected outcomes with respect to the implementation of the strategic alternatives.
Environmental challenges | Major sources | Impact/risks assessment | Strategic alternatives | Expected outcomes |
---|---|---|---|---|
Solid Waste Generation | Chips/swarf generated from machining |
|
Solid waste management by recycling with proper handling of chips/swarf |
|
Grinding dust/sludge | Environmental damage affecting land and water | Grinding sludge treatment (Briquette technology) |
|
|
Air Pollution (stack emission characteristics and fugitive air characteristics) | Heat treatment shop |
|
Plasma carburization |
|
Diesel generator sets (particularly set 2) |
|
Hybrid energy system including at least one renewable energy source |
|
