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.

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. This paper presents the results of a life cycle assessment (LCA) of such a technology currently in development for the production of bio-ethanol from spruce wood chips. Results The Coal-based methanol production strongly affects the environment, so the environmental impacts of coal-based methanol production processes must be assessed.

Cradle-to-gate LCA differences from each production system. The main reasons for each identified difference were pinpointed on a case-by-case basis. Methods Our approach innovatively combined knowledge about the main impact pathways of bioethanol production with LCA which covers the typical emission-related impact categories at the midpoint CPM LCA Database - Ethylene production from cane based ethanol. Several studies on the LCA of gasification of lignocellulosic biomass were conducted and discussed as follows.

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).

LCA will thus help technology developers, researchers and industry decision makers to make well-informed and more sustainable decisions during all stages of the development of a new process.Figure 1 :1System considered in the LCA of the high gravity fermentation technology for production of fuel ethanol compared to current corn ethanol production. We utilize a LCA approach which includes a Monte Carlo simulation of numerous normally distributed input parameters which together account for the combined agricultural and technological variability. This produces a probability density function In this section, the main objective is to present the emissions of the 1G2G integrated ethanol plant in the VSB model considering sugarcane bagasse and straw as feedstock for 2G ethanol.
