“…Other environmental indicators have a positive effect on society when they are diminished, for example through the reduction or removal of pollutants such as greenhouse gasses. This can happen indirectly through research that, for example, identifies ways to make cars weigh less and thereby use less fuel (Peretz et al 2009). Because the way we consume food and energy has effects on natural resources, environments and the global climate, environmental impacts could come through improving energy efficiency, increasing the accessibility and/or use of renewable energy sources, or adopting more sustainable agricultural practices.…”

“…Other studies such as Deloitte (2016 and 2015) reported on research with positive environmental impacts, such as informing the ban on harmful pollutants and increasing sustainable energy generation. Case studies were a frequently used method to describe environmental impacts of research Kings College London and Digital Science, 2015;Peretz, 2009;NERC, 2017), though studies on the impact of NERC research used information described in the funder reports. An analysis on agricultural research used interviews to determine its wider impacts (Rodrigues et al 2010).…”

“…An analysis on agricultural research used interviews to determine its wider impacts (Rodrigues et al 2010). Surveys (Daoud et al 2016;Rodrigues et al 2010;Peretz, 2009) were also conducted alongside literature reviews (Daoud et al 2016;Deloitte, 2016) to gather more wide-ranging impacts. Deloitte (2016) used cost-benefit ratio analysis to determine the impacts of research on the environment.…”

“…In addition, many studies note that the amount of lighter materials in vehicles has progressively increased over the past decades [33][34][35]. There have been many international and multidisciplinary projects that have aimed to improve vehicle energy efficiency and lightweighting vehicle parts [36][37][38][39].…”

A Case Study: Designing for Sustainability and Reliability in an Automotive Seat Structure

Abstract:Recently, sustainability has been a growing concern for many industries and especially for the transportation sector due to it being the second largest energy consumer and largest contributor of anthropogenic greenhouse gas emissions within the European Union. New legal restrictions on the emission rates have forced the automotive sector to examine different fuel-efficient technologies. Vehicle weight reduction is one of the most important methods of improving fuel efficiency and reducing CO 2 emissions. Accordingly, lighter, safer, more fuel efficient, and environmentally sustainable vehicles are a priority for European authorities. In the present work, the passenger seat structure was considered as the area for lightweighting due to its important role in the mass of commercial vehicles in terms of numbers per vehicle. In addition, seat structures presented the best opportunity for weight reduction using new materials and design techniques. Detailed (3D) finite element models of passenger seats were developed for finite element analyses (FEA). To obtain a lightweight and safe seat structure, different materials and thicknesses of profiles were analyzed. Lightweight passenger seat prototypes were developed and an overall 20% weight reduction was achieved including the structural frame, chassis and pillar. In addition, the new passenger seat meets ECE R14 safety norms.

“…The concept has been of special relevance in those sectors directly related to transportation such as aviation and automotive [1][2][3] and indirectly to those concerning the packaging industry [4,5]. The common goal is to reduce weight to decrease fuel consumption and related costs as well as increase the passenger/cargo load per itinerary; weight also has a direct impact on dynamics and agility [6][7][8]. Moreover, looking on the current outlook of environmental preservation, a continuous definition and approval of restrictive regulations or the introduction of CO 2 emissions targets have resumed a stronger focus on weight reduction as a lever to obtain products with a less relevant ecological footprint and a minimized fuel consumption [9][10][11][12].…”

Lightweight Medium-Sized Parts Made of Foamed HDPE Processed via Extrusion Blow Moulding: Analysis of Parison Formation

The manufacturing of medium-sized hollow parts using a foamed high density polyethylene was studied using a conventional accumulator blow extrusion machine and a systematic capture of pictures during the parison formation. To fully monitor the parison formation, several experiments were carried out varying the chemical foaming agent content from 0 wt.% to 2 wt.% and increasing the push extrusion speed. Results pointed out greater wall thickness, diameter, and length of parisons with higher weight percentage of blowing agent and extrusion speed. A full experimental characterisation of parison dimensions was essential to assure a proper prediction of the blowing step. Information was used as input for modelling and simulations of the blowing phase of an industrial container. To validate the proposed methodology, a blow moulding process of a generic container was simulated using Ansys Polyflow v13 software and its finite element analysis which provided an accurate approximation of the wall thickness expected. Further real tests on the simulated container also demonstrated that, in those parisons with a 1 wt.% CFA concentration and higher blowing pressure, there was remarkable improvement on their packaging properties such as decreasing of the total weight of the container and an enhancement of its surface quality.
