Abstract

The forthcoming IPCC 6th Assessment Report has mentioned that the nature-based solutions for carbon dioxide removal are less costly, closer to deployment, and more vulnerable to reversal, compared to technology-based ones. Biochar, produced from biomass through pyrolysis process, is one such nature-based solution that can help reducing greenhouse gas emissions via soil carbon sequestration. Oil palm biomass residues, namely, empty fruit bunches, mesocarp fiber, oil palm frond, oil palm trunk, and palm kernel shell, are abundant in ASEAN countries, especially in Indonesia, Malaysia, and Thailand. These residues can be used to produce biochar through thermochemical conversion, so called pyrolysis. This study aims to provide a literature review on the physicochemical properties of biochar production from the palm oil residues mentioned above in the Southeast Asia region. There are ten parameters reviewed such as yield, physical properties (i.e., moisture content, volatile content, fixed carbon content, and energetic value), as well as chemical properties (i.e., C, H, O, N, and ash content) under different temperatures for all palm oil residues. Future research is field application of biochar for soil carbon sequestration and life cycle assessment of biochar production and field application. It is expected that the study could give information to relevant stakeholders on the potential of biochar from oil palm residues in ASEAN as one of nature-based solutions to reduce GHG emissions.

Abstract

Sustainable municipal waste management is a big challenge for cities in Indonesia such as Sleman Regency, in D.I.Yogyakarta. Waste to Energy (WtE) is one of the methods in municipal waste management. Energy recovery from municipal waste is expected to produce electricity and/or thermal energy and thereby may reduce the amount of waste transferred to landfills. This study aims to evaluate the environmental impact of two energy recovery scenarios of municipal solid waste management in Sleman Regency. Here, we investigated 3 option for MSW management: direct combustion of once sorted waste to produce energy (O-1) , an integrated combustion of inorganic waste through the formation of densified Refuse Derived Fuel (RDF) followed by energy production (O-2) and scenario which are including dRDF and biogas followed by energy production (O-3). The environmental impacts from both scenarios were computed with Life Cycle Assessment (LCA) simulation by using OpenLCA software. The impact assessment include global warming potential (GWP), acidification potential (AP), eutrophication potential (EP) and human toxicity potential (HTP). The LCA simulation results showed that the GWP value of O-1, O-2 and O-3 are 0,6741 kg CO2eq / kWh, 0. 65863 kg CO2eq / kWh, and 0,574 kg CO2eq/kWh respectively. The AP, EP and HTP values for O-3 are consistently lower than that of O-2 and O-3. Thus, the LCA simulation results showed that MSW conversion into dRDF and biogas as a part of WtE technology is more environmentally friendly than direct combustion of MSW to energy.
