Abstract

Jatropha curcas is an inedible oil crop which can grow under semiarid climatic conditions. Its oil can be used straight as fuel to provide energy in remote areas to improve living conditions. The aim of this study is to assess the environmental impacts of the electricity generation from Jatropha oil under West African conditions, by means of a Life Cycle Assessment (LCA). These potential impacts are calculated for four crop managements and compared to the ones of a reference electricity generation from conventional diesel. Data used in this work are from Jatropha plantations set up in Mali since 2006.LCA results show that the potential benefits of the Jatropha systems are highly dependent on the crop management, especially for the fertilization strategy and the promotion of the oilcake. However, in all cases, the Jatropha systems have lower impacts than the reference diesel system by 75% to 96% for abiotic depletion, and by 80% to 97% for ozone layer depletion, and higher impacts by 260% to 1000% for eutrophication, and by 26% to 160% for acidification. In the best case, the Jatropha system can also have lower impacts than the reference system by 76% for climate change, and by 88% for photochemical oxidation.A methodological originality of this work is the inclusion of animal and human labour into the LCA framework. A first model is proposed for the accounting of energy consumption and GreenHouse Gases (GHG) emissions due to labour. Concerning energy consumption, labour is not negligible with a share from 14% to 50% of the total impact of the Jatropha systems; however the highest share of 50% corresponds to the scenarios with the lowest energy demand. CH4 emissions from livestock are also not negligible but second-order in this study since they account for 2% to 13% of total GHG emissions.

Abstract

Generally, power plants have an environmental negative impact, due to emissions released from the power plant process. The Coal-fired power plant is the most dominant in the world. This is due to the relatively cheap price of coal and high calories produced. But on the other hand emissions generated by coal-fired power plants are quite large compared to other types of power plants, while all countries are working to reduce global warming, one of which is by reducing CO2 emissions. Utilization Renewable Energy is one of the solutions in efforts to reduce the use of fossil energy so that there is a decrease in CO2. Biomass is renewable energy which is currently widely used as fuel for electricity generation, Biomass fuel can be used 100% for a plant called PLTBm and can also be a coal-fired power plant with a certain percentage mix. Therefore, an analysis using the Life Cycle Assessment (LCA) method is used to determine differences in emissions produced between coal-fired power plants compared to the Biomass co-firing system. The result is a PLTU with a Biomass co-firing system produces lower emissions than a 100% coal-fired power plant.

Abstract

LCA studies require a high volume of data and their quality has a direct influence on the quality of the Life Cycle Inventory (LCI) and Life Cycle Assessment (LCA) study overall. The use of LCA databases enables users to (i) reduce time, efforts, and resources for data collection and (ii) reflect supply chains they have no direct control over. On the other side, it creates the need to align own modeling of the foreground LCA study with the modeling in the database. In recent years, countries worldwide have been more and more motivated in supporting LCA studies by providing national databases that reflect their economy, energy mix, and disposal technologies. This article aims to give insights on the main needs, requirements, and challenges for the creation of an LCA database, with a special focus on national, reference databases. First, the article defines the main characteristics of LCA datasets and discusses data collection approaches. Secondly, LCA databases are defined, and the creation of LCA databases from developed datasets is addressed, including the case of national LCA databases. Finally, the existence of tools that could ease the LCA dataset and database creation process is investigated, namely the LCA Collaboration Server and the LCA Data-Machine. It is important that countries willing to create a national database are supported, for example with capacity-building workshops, by actors with a long tradition in the field, which is of mutual benefit: Countries with a long tradition in LCA will benefit from interactions with newcomers, for instance by discussing together unsolved methodological and interoperability issues; newcomers do not need to start from scratch but can benefit from gained experiences. Creating databases that provide specific data for various parts of the world supports LCA methodology and application in general, and it is not the least a chance for local LCA communities to bring in innovation into LCA, and benefit from existing experiences at the same time.

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.
