Comparative environmental life cycle assessment of materials in wooden boat ecodesign

Abstract

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Methods In order to validate the choices, we used a life cycle assessment (LCA) Bfrom cradle to grave^of the hull. This LCA is based on the comparison of the following different materials used: aluminum, composite, exotic wood, and maritime pine. This study is based on the construction of an 18-mlong passenger transport boat. These evaluations were carried out with respect to ISO 14040 standards, beginning with an existing database and measurements taken on the building and production sites.Results and discussion Our results demonstrate the benefits of using a wood-based hull compared with other materials. Moreover, the results show that the maritime pine used in replacement of imported exotic woods is more favorable from both economic and environmental points of view. This LCA allowed us to characterize precisely the stages in the life cycle of a passenger boat and to propose a hierarchy of the different materials under comparison for the purposes of boat building.Conclusions The recommendations and lines of progress highlighted by this study will allow us to enhance the efficiency of upcoming constructions and to promote the ecodesign conception in the boatyard.

To transport waste or transport recycling plant: Insights from life-cycle analysis

“…With the LCA results, we were able to compare the mechanical process with the traditional smelting process. As already demonstrated in previous publication [28], the mechanical recycling process makes it possible to halve the impact of recycled aluminium. The summary of the recycling LCA comparison results is shown in Figure 4.…”

“…The study is based on a life cycle approach, in accordance with ISO 14040/44 standards [28,29]. The Figure 7 presents the study scope used for the life cycle comparison.…”

Experimental design to determine the manufacturing parameters of a green-glued plywood panel

“…• those panels matched plywood class 3 requirements according to NF EN 314 (1993); • the best results in shear were obtained for the wood MC of 30 and 60 %, and the MC = 60 % was close to the veneers MC after the rotary cutting step; • the lowest amount of adhesive applied (250 g/m 2 ) is economically and environmentally better (Pommier et al 2015) for companies.…”

Environmental Indicators for the Evaluation of Wood Products in Consideration of Site-Dependent Aspects: A Review and Integrated Approach

“…Rather interesting is the fact that in 51% of all studies the study authors combined at least two methodologies to broaden their investigation. With the help of the functions Configuration Table and Code-Co-Occurrence Model within MAXQDA (see Figure 3), the most common combination pairs could be identified: LCA + numerical modeling [72][73][74][75][76][77][78][79][80][81][82], LCA + eco-design concept [75,76,[83][84][85][86][87][88][89][90][91], LCA + Multi Criteria Decision Analysis (MCDA) [79,[92][93][94][95], and MCDA + Criteria and Indicators [41,44,50,96,97]. Although statistical analyses such as regression analysis, correlation analysis, and cluster analysis are strong tools for the evaluation of empirical data, they were not frequently used throughout the sample.…”

“…In the case of wood products, spatial variability can be considered by the type of sample selection, e.g., by choosing different wood species from different vegetation zones. This was done by Feifel et al (2015) [135] as well as Pommier et al (2015) [90], who compared regional European pine wood with tropical wood from Africa. A prerequisite is that adequate local data exist to discover the differences in the biomass production and pre-processing of the timber.…”
