Abstract

Abstract. Municipal Solid Waste (MSW) which is disposed to unmanaged landfill site  generates the large quantities of greenhouse gas (GHG) called landfill gas. This Landfill gas is composed from various kind of gases, one of  those gases is Methane (CH4 ) that is 21 times more effective than carbon dioxide (CO2) which contributes to global warming. The number of methane gas generated from organic waste has different values depending on the waste characteristics. This study is aimed to calculate the GHG of Bakung landfill which is located at Bandar Lampung city by considering  about the waste characterization using various laboratory testing and the default data of IPCC Inventory software 2006. The Results showed that the landfill is able to generate an average of  2,665 m3 Million methane during 2018 – 2032.Keywords: Bakung landfill site, waste characteristic, greenhouse gas, methane

Abstract

Solid waste has always been a problem for developing countries. In Bandar Lampung, the traditional market is the second largest contributor of solid waste, after households. Data for Traditional Market Solid Waste (TMSW) composition and generation rate in Bandar Lampung is rarely found, even though, data is needed to write the policy for TMSW management and its recycling potential. This research aims to provide data on TMSW composition, generation rate and chararacteristic in Bandar Lampung, also its recycling potential. The sample from 10 of 31 traditional markets in Bandar Lampung is collected for 8 consecutive days in morning and afternoon. Then, the sample was processed to obtain its composition, generation and density. 48.06% of TMSW compositions is donated by vegetable. Meanwhile, metal is rarely found in traditional markets, with only 0.37%. The average density of TMSW is 180.11 kg/m3, while Kangkung Market has the highest density with 237.84 kg/m3 and Cimeng Market has the lowest TMSW density with 123.07 kg/m3. The generation rate of TMSW is 53,602.35 kg/day. Biodegradable wastes from traditional markets in Bandar Lampung, with 53% water contents, can be potentially recycled by composting and/or anaerobic digester because of its economic value and characteristic. Keywords:   Recycling, Solid Waste Management, Traditional Market Solid Waste, Waste Characterization

Abstract

Palm oil mill effluent (POME) and oil palm empty fruit bunches (OPEFB) represent two major waste streams in the palm oil industry that pose serious environmental challenges but also offer significant opportunities for renewable energy generation. This review comprehensively discusses the development of biogas production from POME through anaerobic digestion (AD) and explores the prospects of co-digestion with OPEFB to improve system efficiency and sustainability. A systematic literature survey of over 150 publications from the past four decades was conducted to evaluate technological evolution, operational parameters, methane yield, and environmental implications. The review identifies five major phases of POME biogas development—from early feasibility studies in the 1980s to the current exploitation phase integrating energy recovery, carbon credit schemes, and circular bioeconomy principles. Anaerobic digestion of POME in covered lagoon systems has achieved COD removal efficiencies exceeding 90% and methane yields of 0.28–0.34 Nm³ CH₄ per kg COD removed, supporting electricity generation potentials above 1 GW nationwide. Meanwhile, co-digestion with OPEFB enhances process stability, optimizes the C/N ratio, and improves methane production by 20–40% depending on substrate ratio and pretreatment. The integration of POME–OPEFB co-digestion can substantially reduce greenhouse gas emissions and provide value-added biofertilizers, thereby strengthening the environmental and economic sustainability of palm oil mills. Despite technological advances, several challenges remain, including high investment cost, OPEFB pretreatment, and limited policy support for grid connection. Further development of scalable, low-cost digesters and biogas upgrading systems is essential to realize the full potential of biogas as a renewable energy pathway within the palm oil sector.
