Energy Consumption and Greenhouse Gas Emission from Ceramic Tableware Production: A Case Study in Lampang, Thailand

摘要

This paper presents energy consumption and greenhouse gas (GHG) emission from ceramic tableware production in Lampang, Thailand. All data of energy consumption in ceramic production were collected from a small enterprise manufacturing plant and the unit of analysis was 1 kg of product. A scope of study was gate to gate. The amount of GHG emission in a unit kgCO2e/kg of product was calculated by 2006 IPCC Guidelines for National Greenhouse Gas Inventories method and the emission factors were referred from Thailand Greenhouse Gas Management Organization (TGO) and IPCC databases. The results showed that the total energy consumption from ceramic tableware production was 24.28 MJ/kg of product and almost 98% of total energy consumption was from liquefied petroleum gas (LPG) consumption during firing. The amount of GHG emission was 0.237 kgCO2e/kg of product. The glost firing was found to be a hotspot of energy consumption and GHG emission.
