Palm Factory Circularity Indicators Based on Various Palm Oil Mills Effluent Processing Technologies

Abstract

Apart from Crude Palm Oil (CPO), which is the main product, the process of converting FFB to CPO also produces liquid waste known as liquid palm oil waste or Palm Oil Mill Effluent (POME). In the framework of this analysis, POME is also considered a product because it has economic value and benefits that allow it to be further processed into new products, so the circularity value will be calculated. The research approach uses the MCI circularity indicator developed by the Ellen MacArthur Foundation in assessing circularity indicators for various POME waste management scenarios in palm oil mill. From various POME processing governance scenarios, namely: 1) Processing POME with biogas technology lagoon system, 2) Processing POME with biogas technology with a CSTR system, and 3) Processing POME into with composting and 4) Based on government regulations regarding POME processing in palm oil mills with open ponds processing. Based on the assessment results based on these various scenarios, the MCI circularity values obtained are 1)0.5781; 2)0.6143 and 3)0.7065, and 4)0.5500;. The highest MCI circularity value is produced by processing POME into composting.
