100% recycling

- Using bottom ash for light aggregate, fly ash for cement

- Remaining ash will be used for mine back fill

- No need for an ash pond

Ⅳ. Clean Energy Production

1. SNG

KOSPO operates a number of CCPP

Hard to introduce LNG directly

Coal gasification as an alternative fuel

Coal gasification using low grade coal

Keep in LNG storage tank &

use for CCPP alternative fuel

SNG

2. Small Hydro-power

Using discharge

Capacity : 5,500 kW (1,375kW x 4

Units)

Type : Kaplan
