Abstract

The emission factor (EF) describes the relationship between pollutants released into the atmosphere and associated activities. Developing specific EFs is essential for accurate emission calculations in the industrial sector, particularly in coal-fired power plants (CFPPs), a major source of emissions in Indonesia. This study aims to develop specific CO2 EFs for CFPPs in Indonesia by analyzing the influence of power plant characteristics, such as technology type and age, on the EF values. The EFs, expressed in tons of CO2 per unit of energy produced (t TJ-¹), are based on data from 153 units across 66 CFPPs in Indonesia. Five technology types were included in the analysis: ultra-supercritical, super-critical, subcritical-pulverized coal combustion, subcritical-fluidized bed combustion and subcritical–stoker. The study compares the resulting CO2 EFs with the IPCC-2006 default value for sub-bituminous coal and Indonesia’s national EF for medium-quality coal. The average CO2 EF for Indonesian CFPPs was 100.16 t TJ-1, higher than the IPCC-2006 default value (96.1 t TJ-1) but slightly lower than Indonesia’s national EF (100.575 t TJ-¹). A statistical test revealed significant differences between technology and age groups, but post-hoc analysis showed no strong correlation was found between these characteristics and the EF values within specific groups. This indicates that the EF, based on fuel characteristics, is not directly influenced by these plant characteristics. It is hoped that the CO2 EF values obtained from this study will better represent actual conditions, provide a more accurate emission calculations and supporting the development of better emission inventories for cleaner energy generation.

Abstract

The cement industry is one of the sectors that produces carbon dioxide (CO2) emissions due to its raw material processing and energy requirements. CO2, as a greenhouse gas (GHG) emission, contributes to global warming, leading to environmental, health, and economic losses. To address these issues, Indonesia is committed to reducing GHG emissions in the industrial sector by 2050. To effectively plan for the reduction of GHG emissions generated by companies, this study aims to quantify emissions from a cement company, representing the cement industry in Indonesia, to understand the current state of the company's carbon footprint and identify feasible mitigation measures. The cement industry utilizes a GHG quantification system to calculate emissions from raw material processing, thermal energy consumption, and electricity purchases. The calculation results from a cement company are used for system dynamics modeling with Vensim PLE software for the period from 2021 to 2050, under business-as-usual (BAU) conditions with various emission reduction strategies. The results show that GHG emissions under BAU conditions with emission reduction strategies do not achieve carbon neutrality by 2050. More intensive adoption of decarbonization technologies, research on process optimization, and government policies such as carbon taxes and carbon trading are required to achieve carbon neutral goals.

Abstract

Coal-fired power plants (CFPPs) have significant negative environmental impacts due to emissions from non-fugitive sources like stacks. This research aims to predict the concentration, dispersion patterns, and health risks of pollutants emitted from these plants, focusing on SO₂, NOₓ, and TSP using the AERMOD model. Meteorological and terrain data were processed through AERMET and AERMAP. Results indicate that pollutants mainly disperse to the east and south, with peak concentrations 1.5 to 2 km south of the source. SO₂ concentrations reached 15,121.18 µg/m³ (1-hour), 5,740.66 µg/m³ (24-hour), and 287.67 µg/m³ (annual), exceeding regulatory limits. NOₓ peaked at 15,589.02 µg/m³ (1-hour), 5,782.41 µg/m³ (24-hour), and 288.48 µg/m³ (annual), also surpassing limits. TSP concentrations peaked at 330.30 µg/m³, exceeding the 24-hour limit. Model validation showed good accuracy for SO₂ but overestimated NOₓ and underestimated TSP. Health risk assessments identified 23 high-risk locations for SO₂ and one for NOₓ during 24-hour exposure, while TSP posed no significant risk. Recommendations include improving model accuracy by incorporating fugitive sources and chemical transformation modules to enhance air quality management in complex terrains.

Abstract

The Coal-Fired Power Plants with low-emissions plants in the power sector can avoid nearly 800 million tonnes CO2 by 2030. The number of populations, Gross Domestic Product (GDP), electricity generation, NDC, and relevant energy policies influenced the prediction of Carbon Dioxide (CO2) emission from electricity generation. Aim: The objective is to analyze trends of CO2 growth related to electricity generation activities from countries in ASEAN with an emphasis on identifying the factors that influence it and evaluating the effectiveness of existing decarbonization policies in AMS and developing suitable strategies to reduce future CO2 emissions. Methodology and Result: Predicting CO2 emissions is conducted using three approaches by considering the newest NDC and energy policies, conducted by descriptive and quantitative analysis based on secondary data of (1) general information on ASEAN Member States (AMS), (2) information on power plants, (3) information on fuel use in electricity generation, and (4) decarbonization policies in AMS. Results indicated that the availability of potential energy sources (coal/oil/gas/RE) influences the dominant energy used in AMS Prediction of CO2e emission in the 2020 to 2040 period identified Vietnam as one of the highest CO2e emitters (380,1 Mt CO2e) in the electricity sector by 2030. Conclusion, significance and impact study: AMS needs to make a more aggressive energy policy to reduce CO2 level significantly, achieving the 2050 net zero transition targets. Ultimately, the shifting from coal-fired electricity plants to other fuel sources with a lower emission factor proves to be the most significant factor towards emission reduction.

Abstract

The textile industry has the biggest impact on environmental pollution in the world, and is responsible for 10% of global carbon production. Most of the waste in the textile industry, is generated from the dyeing process and textile processing. PT X is a textile finishing industry, that focuses on finishing processes like dyeing and textile processing. In this research, GHG (greenhouse gasses) emission inventory was carried out to see how much GHG generated in the textile finishing industry. The inventory will focus on CO2, CH4, and N2O from generator, curing machine, operational vehicle, and electricity usage. The inventory methodology was based on IPCC 2006, that stated to determine GHG emission, an activity data and emission factor from that source is needed. This emission inventory results on the total emissions of 666.38 tonCO2eq or 258.629 kgCO2eq/tonproduct GHG emission from PT X in 2021. The GHG emission in PT X are dominated by CO2 gas. Which most of comes from electricity usage source. GHG emission produce by PT X are not high compared with similar industries, but can be improved further more with mitigation measures such as installing a solar panel, and constructed wetland.

Abstract

Although Indonesia has set a target for increasing the use of renewable energy for electricity generation, the use of coal as a source of energy will still dominate at least until 2040. Sulfur dioxide (SO2) along with other gases and particulates released from the use of coal in coal-fired power plants (CFPPs) may cause air pollution. The use of seawater, an abundant source of absorbent in a maritime country such as Indonesia, in flue gas desulfurization (SWFGD) absorbers, is an economical option for treating SO2 in an absorption tower compared to other alkaline chemicals, e.g. limestone (CaCO3) or magnesium hydroxide (Mg(OH)2). A model, which correlates the equilibrium of the reaction with the salinity of the absorbent, was developed to predict the sulfur dioxide scrubbing process inside an SWFGD absorber. The simulation also took into account the mass and energy balance during the scrubbing process. The calibration using field SWFGD data showed a good correspondence between field data and modelling results.
