“…So far, many studies on the life cycle assessment of bioethanol as transport fuel focus on first-generation bioethanol, which is converted from conventional crops, such as corn, wheat, sugar cane, and sugar beet (Halleux et al 2008;Luo et al 2009b;Patyk and Reinhardt 2002;Shapouri and McAloon 2002). It has been signaled that producing energy from such crops is very land and water intensive (Nguyen and Gheewala 2008;Renouf et al 2008;Silalertruksa and Gheewala 2009). Global demand for food is expected to keep increasing in the future (Rosegrant et al 2001), and demand for transportation fuels is expected to increase even more rapidly (Energy Information Administration 2009), which implies a potential competition between land for food and land for energy.…”

“…In addition, 1,4 butanediol can be produced from succinic acid and bio-ethanol. The molasses ethanol was used for the case of SPBS, the inventory data were from Silalertruksa and Gheewala [34]. For the case of CPBS, cassava-based ethanol was used by utilizing inventory data from Silalertruksa et al [32].…”

Bioplastics demand has been increased globally due to concerns regarding environmentally friendly consumption and production. Polylactic acid (PLA), polyhydroxyalkanoates (PHAs), and polybutylene succinate (PBS) are promising bioplastics with bio-based feedstocks and property of biodegradability. They are produced by bacterial fermentation of sugars from carbohydrate sources. With flexibility in their properties, PLA, PHAs, and PBS can potentially substitute conventional plastics such as polypropylene (PP), polyethylene terephthalate (PET), and polystyrene (PS). This study aims at evaluating the environmental and economic sustainability of bioplastics production together with end-of-life (EOL) options. The combination of environmental and economic indicators, eco-efficiency (E/E), was selected to investigate the performance of PLA, PHAs, and PBS from sugarcane and cassava in comparison with PP. The environmental impacts were determined using life cycle assessment. The product cost was used to represent the economic value. The E/E results showed that the environmental and economic sustainability could be enhanced with 100% mechanical recycling of all kinds of studied plastics. It is also important to highlight that mechanical recycling showed a better performance in terms of E/E than composting of bioplastics.

“…The research on the macro level mainly focuses on sustainable development of the world environment, countries and industrial sectors, and criteria systems were established mainly from four aspects of society, economy, environment and policy [2,3]. For the sustainability assessment of sectors, the industrial sector, transportation sector, product manufacturing and electric power system [4][5][6][7] are often set as the research objects. The research on the micro level mainly focuses on sustainable evaluation of enterprises and projects [8,9].…”

Abstract:The electric power industry is of great significance in promoting social and economic development and improving people's living standards. Power grid construction is a necessary part of infrastructure construction, whose sustainability plays an important role in economic development, environmental protection and social progress. In order to effectively evaluate the sustainability of power grid construction projects, in this paper, we first identified 17 criteria from four dimensions including economy, technology, society and environment to establish the evaluation criteria system. After that, the grey incidence analysis was used to modify the traditional Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS), which made it possible to evaluate the sustainability of electric power construction projects based on visual angle of similarity and nearness. Then, in order to simplify the procedure of experts scoring and computation, on the basis of evaluation results of the improved TOPSIS, the model using Modified Fly Optimization Algorithm (MFOA) to optimize the Least Square Support Vector Machine (LSSVM) was established. Finally, a numerical example was given to demonstrate the effectiveness of the proposed model.
