Banda Aceh, Indonesia, populated with 250.000 inhabitants, produces 180 tons of waste daily. But only 165 tons are delivered to its 21 ha area of municipal landfill facility, the Gampong Jawa Landfill (GJL). Since 2009, GJL stopped the open dumping practice and switched to sanitary landfill system. However, landfill gas (LFG) generated is still naturally venting out into the atmosphere.
For leachate treatment, GJL has an anaerobic, an aerobic, and a maturation pool. There is also an advanced biogas reactor, namely the Intermediate Treatment Facility (ITF), which has 40 kW electricity generating capacity. Two Waste Water Treatment Plant (WWTP) systems also available, functioned to process human excrements with total capacity of 130 cubic meter.
This research is conducted to study the potential electricity generation from all-combined available resources in GJL. It includes potentials from landfills, ITF, and WWTPs. Literature review, in-depth interviews, field survey, and spread-sheet simulation are methods that have been conducted to achieve the objectives. The result shows that GJL could benefit more than sufficient electricity for its own operations, and transmit the rest to the National Power Grid. Furthermore, all potential is then monetized by utilizing the new Indonesian Feed-in Tarif (FiT) regulations. And the Certified Emision Reductions (CERs) is also expected to be traded through Clean Development Mechanism (CDM). Life Cycle Cost Analysis (LCC) was utilized to examine future projections through a comprehensive financial analysis.
