“…Teaching LCA includes providing concepts of processes, technical norms and computational tools. LCA is an environmental tool to account for and assess environmental aspects and potential impacts related to products, services or processes ISO (2006a) jointly with its whole or partial life cycle (Piekarski et al, 2014). LCA is a well-accepted method for quantifying environmental impacts (Ingwersen et al, 2012).…”

Purpose The purpose of this paper is to report on a life cycle assessment (LCA)-based ecodesign teaching practice via university-industry collaboration in an industrial engineering undergraduate course. Design/methodology/approach A new course was designed and taught in the Industrial Engineering undergraduate course of a Federal University in Brazil. The course comprised explanatory lectures and a practical project developed in a partnership between the university and an industry partner where students had to develop Ecodesign proposals based on LCA to improve the environmental profile of both solid and reticulated paint brushes. To that end, students used the LCA software tool Umberto NXT v.7.1.13 (educational version), where they modeled the life cycle of four plastic brushes and assessed it using the impact categories of climate change and resource consumption, and the Ecoinvent v.3.3 database. After course completion, students, professors and industry collaborators were asked to provide feedback on the project performance and expectations. Findings The course design used was welcomed by both students and the industry partner. Students found the novel approach intriguing and useful to their future careers. The results also exceeded the industry partner’s expectations, as students formulated valuable insights. Professors observed that learning was made easier, as content was put into practice and internalized more easily and solidly. The approach was found to be a win-win-win. Practical implications Students acquired a fair share of knowledge on sustainability issues and potential existing trade-offs, which is valuable to industrial practices. The industry noticed the valuable contributions that academia can provide. The university profited from providing students with a real case challenging traditional teaching methods. Originality/value To the best of the authors’ knowledge, this is one of the first case studies to show how LCA and ecodesign teaching practice can support sustainability learning in an industrial engineering undergraduate course.

“…Among the recycled fi breboards, MDF boards are very often used in furniture industry. However, these contain also resin and other additives that are blended with the fi bres (Piekarski et al, 2014). There are no reliable literary sources referring to 2G bioethanol produced from fi breboards and particle boards and this work has the ambitions to change this.…”

Pretreatment of particles obtained from lignocellulosic materials by steam explosion with indirect control by enzymatic hydrolysis has been studied. The dendromass pretreatment model has been applied for recycled fibreboard and particle board based on softwood. Their structure and chemical composition partly predetermine these lignocellulosic materials consisting of a mixture of spruce and fir particles also for bioethanol production. Optimum steam explosion temperature of 205 °C was determined based on the concentration of total monosaccharides — glucose, xylose and arabinose, among all experimentally prepared hydrolysates. This corresponds to basic conditions for fine disintegration of biomass to lignocellulosic structure with good holocellulose accessibility. Particles obtained from fibreboard and particle board primarily consisting of softwood without steam explosion pretreatment provide relatively low cellulose accessibility for commercial enzymes activity while monosaccharides concentration is partly reduced because of torrefaction at high temperatures. The concentration of monosaccharides in hydrolysates was determined for original sample and each steam explosion temperature. Based on the steam explosion conditions, the effect of severity factors was investigated to find optimum pretreatment conditions to increase accessibility of softwood cellulose and hemicelluloses. The identified optimum severity factor RO = 4.09 matches the optimum steam explosion temperature of 205 °C and the residence time of 10 minutes.

“…Mediumdensity fiberboard was assessed based on LCA during the production process [25,26]. Umberto software and Ecoinvent life-cycle inventory database were used to establish different life-cycle models of fiberboard manufacturing [27][28][29]. Some applications of LCA in power generation were carried out as a life-cycle assessment of straw power generation in Spain.…”

Crop straw, as a widely used biomass resource, can be processed to produce renewable energy and green products. However, about 70% of straw were burned in the open air, causing serious environmental pollution and air pollution. In order to reduce the burden on the environment, the different straw management strategies are comparatively studied and evaluated by applying the life-cycle assessment (LCA) method. Within the system boundary from cradle to grave, three alternative scenarios, including straw particleboard, straw cement-bonded particleboard, and straw direct combustion power generation, are compared with the current common treatment (straw open burning). e comprehensive inventory analysis on each treatment scenario is carried out indepth, and the corresponding resource consumption and environmental impact of each treatment scenario are calculated, respectively. e LCA results showed that the environmental impacts of reusing crop straw to produce straw particleboard and cement-bonded particleboard (Scenario 1 and Scenario 2) is significantly reduced by 6% and 10%, by comparison with the use of wood resource. Greenhouse gas emissions from straw direct combustion power generation (Scenario 3) processes are reduced by 30% compared with coal power generation. From the environmental point of view, the scenario of straw particleboard product has the smallest impact on the environment, while straw open burning is not an advisable way due to the highest environmental impact from the highest greenhouse gas emissions and acidification effects. From the perspective of energy consumption, the energy consumption for the combustion power generation is the smallest in all scenarios. It is suggested that governments are supposed to construct reasonable scenarios for the straw disposition based on the local development status and condition. e research results can provide scientific guidance for the management strategy of the comprehensive utilization of straw resources.
