Potential clay from Bali to support clean production in the Bali ceramic industry

Abstract

The challenges for the Bali ceramics industry come from the emission side of the materials, production, and waste processing. In the future, the Balinese ceramics industry must develop to be greener and more sustainable. One of the way is reducing emissions from raw materials process. This research was conducted with the aim of mapping the potential of clay that can be used as a raw material for making ceramics, especially those from Bali. The method used was to review the literature on ceramic raw materials and conducted a survey to compile flow diagrams of materials, energy, and emissions from ceramic production in Bali. Then calculated the carbon dioxide (CO2) emissions that arise with the clay scheme come from inside and outside Bali. The results of the study indicate that there is potential for the use of clay from Buleleng and Tabanan areas, which can reduce carbon dioxide (CO2) emissions of the Balinese ceramic industry. However, its use needs to be re-examined from a process perspective because it has a higher iron oxide (Fe2O3) composition.
