| Abstract | Facing rising environmental concerns in the industry sector, especially sugar industry, requires to assess environmental performances. Minimizing the environmental impact like eco design is vital to save the earth. Life cycle assessment (LCA) is applied to know the impact of sugar production from agricultural stage to industrial stage, without considering their usage and disposal phases (cradle to gate). Eco Indicator 99 (H) is used as life cycle impact assessment (LCIA) methods in this study. Life cycle of sugar from sugar cane in Kebon Agung sugar company, East Java province, Indonesia is analyzed by SimaPro 7.3.3 software.
The total emission covering cradle to gate with one ton of sugar as functional unit is 508 Pt. Agricultural stage especially fertilizer usage is the largest source of emission in the whole sugar processing with dominant emissions in carcinogens and land use categories. It contributed 86% of whole impact. The contribution from de-ionsed water and burnt lime are also significant to give emission during industrial stage. It mainly affected respiratory inorganics impact category.
Lacking technology to process by-product is commonly found over Indonesia sugar industry. It can be seen clearly when it compared with other sugar industry. It is important to implement the scenario improvement in sugar industry. The first scenario is utilization of filter cake as fertilizer. The total emission was reduced by almost 20%. By using molasses as biofuel as second scenario, it decreased 9.25% total environmental impact. The third scenario is applying mixed 40% dolomite and 60% burnt lime in juice clarification station. It decreased 0.78% of total emissions. |
