In the LCA procedure, three separate but interrelated components: inventory analysis, characterization and Abstract. In this work, a life cycle assessment (LCA) estimating greenhouse gas (GHG) emissions and net energy value (NEV) of the production of gasoline and diesel from forest residues via fast pyrolysis and hydroprocessing, from production of the feedstock to end use of the fuel in a vehicle, is performed. 2019-12-30 · Ethanol Production.

This includes indirect inputs to the production process and associated wastes and emissions, and the downstream fate of products in the future. These biorefinery systems are investigated using a Life Cycle Assessment (LCA) approach, which takes into account all the input and output flows occurring along the production chain. Life-cycle assessment (LCA) of ethanol produced by bioconversion of willow has been investigated for Europe using the information of feedstock production available in literature from the United Kingdom (Stephenson et al. 2010).

Two different methods for streamlined life cycle assessment (LCA) are Both methods are tested on an already made case-study on cars fuelled with petrol or ethanol, and electric cars with electricity produced from hydro power or coal.

About the project. Sustainability performance of biofuels is often evaluated using life cycle assessment (LCA). Based on this method standardized guidelines has

2017-02-23 · Some LCA studies have taken steps towards investigating the potential environmental benefits of co-locating and partly integrating enzyme production with ethanol conversion [10–12], but the full potential of an integrated process approach, using part of the lignocellulosic feedstock for enzyme production, has only recently been addressed [37, 38]. Abstract Background Development of more sustainable biofuel production processes is ongoing, and technology to run these processes at a high dry matter content, also called high-gravity conditions, is one option.

Life cycle assessment (LCA) methodologies have been used to evaluate the LC of ethanol to determine if environmentally preferable and economically viable ethanol can be produced in Ontario, Canada. A novel continuous stirred tank bioreactor has also been developed CHAPTER 4. Life Cycle Assessment of switchgrass and corn stover ethanol production in the Wisconsin and Michigan agricultural contexts..117 . PART 1. LCA of Switchgrass Cellulosic Ethanol Production: Testing LCA results In this context, the Life Cycle Assessment (LCA) was used to estimate the effective carbon emissions of RJF from sugarcane, considering 1G ethanol and 2G ethanol processes (enzymatic hydrolysis Table 7 presents the results not normalized gotten for 1 kg methanol (functional unit).The results of LCA of this work were compared with others studies, such as the work in Ref. [32] that conduced the LCA study of the ethanol from sugarcane with a system boundary that involves four stages of ethanol production: sugarcane farming and harvesting, sugar milling, ethanol conversion (by fermentation technology), and transportation during each stage.The CML 2 method was applied and the Allocation is only done in the ethanol production. The outputs from the ethanol production are ethanol and the by-product pulp. Emissions and primary energy demand are allocated between the ethanol and the pulp.

The outputs from the ethanol production are ethanol and the by-product pulp. Emissions and primary energy demand are allocated between the ethanol and the pulp. Energy allocation is based on the following energy contents: sugar beet 17,6 MJ/kg, pulp 16,8 MJ/kg: Systems Expansions: No. Our BAU scenario assumes a continuation through 2022 of current trends in average corn yields per hectare, process fuel switching from coal to natural gas, and increasing fuel efficiency in heavy -duty trucks. Based on these trends, we project life -cycle GHG emissions for corn ethanol in 2022 at 54,588 g CO. 2.

The results of the environmental impacts were compared to others LCA studies of biofuel and it was showed that there are significant differences of environmental performance among the existing biofuel production system, even for the same feedstock.

Life-cycle assessment (LCA) of ethanol produced by bioconversion of willow has been investigated for Europe using the information of feedstock production available in literature from the United Kingdom (Stephenson et al. 2010). In this study, the impacts associated with conversion were estimated using the Aspen model developed by the By comparing the life cycle assessment results of ethanol production from the cassava root, cassava straw and whole plant cassava, it can be seen that the integrated production process can produce bioethanol efficiently and cleaner. However, it is not sufficient to use data only from process simulation literature for LCA. different system choices in LCA for ethanol production: An assessment Mahasta Ranjbar a, Réjean Samsonb and Paul R.
