Use Phase

In today's society the continuously increasing consumption of raw materials and the associated impacts on the ecosystem tend to be a frequently discussed topic. Especially automobile companies are faced to develop new driving concepts due to the emerging energy turnaround. Usually the components of the conventional drive are replaced by an electric engine including the required energy storage. Without structural changes regarding the chassis this procedure causes an increase in the vehicle ́s weight (Conversion Design). Therefore a new approach is to integrate the battery as a load-bearing member in the vehicle structure and additionally use a weight-optimized multi-material design of the body (Purpose Design). By savings of 25% of the weight of a compact-class vehicle body, a resource-saving and energy-efficient design of the entire vehicle can be achieved. Certainly the innovative multi-material construction contributes significantly to reduce the total energy consumption of the vehicle during the use phase. Based on a Lifecycle-Assessment (LCA) the environmental sustainability of the Purpose Design will be evaluated and compared to the approach of the Conversion Design. In addition to the weight savings of the multi-material body secondary weight reductions regarding the energy storage will be taken into account. The aim is to assess the ecological advantages of the lightweight solution throughout the entire product life cycle comprising the extraction of raw materials, production of the components, use of the product and end of life including the recycling of components. However, these investigations will be carried out for the modified chassis and the lightweight constructed multi-material body. Hence, the processes of the individual life cycle phases will be collected, inventorial analysis carried out and impact assessments performed. According to the LCA it will be tested, if the additional expenses in raw material extraction, production and recycling of the lightweight body justify the expected ecological advantage in the use phase. A final overall analysis will provide information on the actual efficiency and sustainability of the Purpose Design. Due to the parallel creation of the LCA data during the development process the LCA results furthermore serve to detect and monitor significant shortcomings on component and assembly level.

Forward Logistics

As the power of consumers is growing, the product return for customer service and customer retention has become a common practice in the competitive market, which propels the recent practice of reverse logistics in companies. Many firms attracted by the value available in the flow, have proactively participated in handling returned products at the end of their usefulness or from other parts of the product life cycle. Reverse logistics is the flow and management of products, packaging, components and information from the point of consumption to the point of origin. It is a collection of practices similar to those of supply chain management, but in the opposite direction, from downstream to upstream. It involves activities such as reuse, repair, remanufacture, refurbish, reclaim and recycle. For the conventional forward logistics systems, the flow starts upstream as raw materials, later as manufactured parts and components to be assembled and continues downstream to reach customers as final products to be disposed once they reach their economic or useful lives. In reverse logistics, the disposed products are pushed upstream to be repaired, remanufactured, refurbished, and disassembled into components to be reused or as raw material to be recycled for later use.

This article summarizes the arguments within the scientific discussion on the issue of using mining machines and their life cycle. The main goal of the article is to investigate the impact of a combination of mobile and stationary mining machines and their optimal distribution in the mining process to increase the efficiency of mining and processing of raw materials. The following methods of research were focused on the use of technical indicators for the valuation efficiency of the mining process: a simulation method was used for the distribution of mining machines, comparison analysis was used for the real and past state of mining machines, and a decision tree was used as managerial instrument for optimal alternatives of mining machines. The research empirically confirms and theoretically proves that optimal distribution of mining machines and machine parks is very important for mining companies. The benefit of this research for the mining company was the new location of the machines and the combination of stationary production lines and mobile equipment. The optimal layout of the machines reduced the number of conveyor belts and improved the transfer of limestone processing to mobile devices, saving time, which was reflected in transport costs. The results can be useful for other mining companies seeking to create an optimal machine park.

Abstract This paper presents the concept and implementation of the Green Browser, which enables designers and consumers to share environmental information. We propose the conceptual scheme of the Green Browser called green life cycle model. This model is intended to represent the product’s environmental impacts over the stages of raw materials, use, recycling, and disposal. The Green Browser has been implemented using WWW and MOO to be able to deal with the strategy model, which is the key element of the green life cycle model. A case study on building the strategy model of refrigerator is presented to illustrate the strategy model.

PurposeThe paper aims to propose the development of an eco product to replace the traditional cotton swab that meets the expected needs, besides having a bias based on sustainability and economic viability.Design/methodology/approachThe applied nature article opted for an exploratory and descriptive study, with the objective of seeking a solution to a real problem: to reduce the environmental impact in the disposal of cotton swabs. To test this hypothesis, the exploratory stage evaluated the literature on the principles of eco design and environmental marketing to understand market viability and environmental impacts. The descriptive phase presented a comparative analysis between the original product and the proposed one, in terms of production processes and impacts of the product life cycle. Thus, an alternative product was conceived and validated applying the life cycle analysis (LCA).FindingsThe paper provides a comparative analysis between the eco product and the traditional product in order to validate the hypothesis that the new proposal reduces the environmental impact. It was found that both productive processes have similar impacts; however, the raw material of the proposed eco product demonstrated a significant reduction in the impact caused on the environment, considering cradle to cradle analysis.Originality/valueThis paper conceives an eco product as an alternative to traditional cotton swab, presenting an innovative potential in line with worldwide sustainability trends.

This work investigated the recycling of fly ash waste and cullet as the raw materials for lightweight bodies produced by heat treatment and using sodium silicate as the binder. Borax was mixed with fly ash and cullet, and put into the block in dimension 10x10x2 cm3. The lightweight materials thus produced were then sintered at temperature of 800 °C. Density, compressive strength and thermal conductivity were determined. Borax showed a positive sintering effect on the porosity of lightweight material during the heat process. The compressive strength of lightweight material diminished with the reduction of density and thermal conductivity. Lightweight material manufactured with borax showed the lower density and thermal conductivity accompanied by the higher compressive strength. The test results indicated that using fly ash and cullet as the raw material with borax could obtain the lightweight material, thus enhancing the possibility of its reuse in a sustainable way.

Sustainable Product

Sustainable product design plans the entire life cycle of a product from its raw material selection, conceptual and structural formation, manufacturing processing, and usage to its end-of-life, reuse, and recycle. The product design needs the sustainable knowledge and proper tools. Current computer-aided design systems are insufficient to represent complex relationships of product functions, structures and life cycle options. It is required for design tools to support product life cycle planning with multi-objective optimal solutions. In this paper, our experience in design of a wheelchair is used as an example to discuss the need of design tools. The aim is to define ideal tools for design of sustainable products.
