Every year INALUM has produced around 500-1000 ton spent brick lining which placed in the dump yard. After it has been placed, it sells to the third party. Spent Brick lining which has been cleaned has no or little harmful content and some chemical composition can be utilized as a new product as the refractory application in INALUM. Some research proves that spent brick has some good mechanical properties if applicated as concrete and INALUM’s spent brick production high enough to fulfill castable needs in INALUM in a year. The General flow process of castable making is sorting and drying, crushing and grinding, screening, mixing (with other aggregate and additive). With this general production, its predicted to produce earnings after taxes (EAT) around IDR 678.232.000 per year.
