Abstract

Hazardous waste from the cement industry can pollute the environment and human health. The use of cement industry waste can be done to minimize this impact. This study aims to analyze the initial conditions of hazardous waste management in the cement industry and its potential utilization. This research was conducted by field observation through three stages, namely the stages of preparation, implementation, and preparation of reports. The XYZ cement industry has two procurement schemes, polutter payment and purchase. The XYZ cement industry permits hazardous waste as an alternative raw material (ARM) for fly ash, bottom ash, paper sludge, drilling cutting, crude oil, contaminated soil, and bleaching earth/eco oil, EAF (electric arc), and dust furnaces. Meanwhile, alternative fuel (AF) consists of used bag cloth, majun (contimated textile waste), used oil, kluber, used grease, resin, and pure SBE (spent bleaching earth).

Abstract

Cement is a prominent Indonesian industry. Industrial fuel needs are growing. In Indonesia, biomass is an essential natural resource with a variety of primary products such as fiber, wood, oil, food, and others that are utilized domestically and exported to generate foreign cash. This study compares fly ash and bottom ash as alternative fuel feedstock materials from the cement industry. This study uses cement industry data from East Java. As, Cd, Cr, Pb, Hg, TI, Sb, Co, Ni, Cu, V, Zn, Se, and Sn for bottom ash and fly ash quality data are employed. The investigation followed a paired t-test to compare ash types based on metal characteristics, then an ANOVA post-test to establish the significance of bottom ash and fly ash values. The paired t-test on two types of ash showed a 0.103 difference. ANOVA shows that ash kinds differ significantly. Bottom ash and fly ash have different qualities. Hence their management requires various approaches. This treatment utilizes bottom ash. For fly ash, the quality-related parameters must be lowered.
