The focus of environmental work in manufacturing companies has increasingly shifted from end-of-pipe solutions to the environmental performance of products and services. The product development process is central to creating value for customers. This thesis argues that companies can simultaneously create value for consumers and be profitable while taking environmental considerations into account. Modernising ecodesign means taking advantage of environmental benefits and the innovation potential when developing solutions rather than using ecodesign simply to ensure that legal requirements or customer demands are met. Ecodesign is a strategic issue and should be included in early product development activities, such as for project selection and when setting product targets. There is also need to perform ecodesign according to the characteristics of specific development processes as for radical product development or when developing integrated solutions, using a combination of services and products. This thesis reports on the findings from five different research studies, all of which adopted a qualitative approach in which the emphasis falls on exploring and creating understanding and meaning. The studies focused on three areas of ecodesign: A) rethinking approaches for manufacturing companies, B) setting environmental project targets and project selection and C) redesign of products. Recommendations on how to modernise ecodesign have been developed and can be summarised in six points: • Perform ecodesign both vertically and horizontally in a company. • Increase interaction between organisational units. • Take advantage of innovation potential in products, services, user behaviour and the delivery and take-back systems. • Take environmental considerations into account in the project selection process. • Set environmental targets for ensuring that environmental considerations are taken when developing innovative solutions. • Develop ecodesign procedures that fit the characteristics of the development process

Given a special focus on Design for Environment (DfE) methods and tools, the objectives of this thesis are to, “Identify basic design-related requirements that a method or tool should fulfill in order to become actively used by engineering designers”, and to “Investigate how those basic requirements could be used to make DfE methods and tools more actively used in industry among engineering designers”. The research has shown that designers in general have three main purposes for utilizing methods and tools, of which the last two could be seen as subsets of the first one. The purposes are to: (1) facilitate various kinds of communication within the product development process; (2) integrate knowledge and experience into the methods and tools as a know-how backup; and (3) contribute with structure in the product development process. The low degree of follow-up implies a risk that methods and tools are used that affect the work within the company in a negative way. In order to be able to better follow-up methods and tools regarding both their utilization and usefulness, there is a need for a better definition of requirements for methods and tools. Most of all designers’ related requirements are related to their’ aims to fulfill the product performance and keep down the development time. This can be concluded as four major requirements, that a DfE method or tool, as well as a common method or tool, must exhibit: (1) be easy to adopt and implement, (2) facilitate designers to fulfill specified requirements on the presumptive product, and at the same time (3) reduce the risk that important elements in the product development phase are forgotten. Both these two latter requirements relate to a method or tool’s degree of appropriateness. The second and the third requirements are related to the fourth requirement, which is found to be the most important: that the use of the method or tool (4) must reduce the total calendar time (from start to end) to solve the task. The conclusion is that DfE methods and tools must be designed to comply to a higher degree with the main users - in this case the designers’ requirements for methods and tools / QC 20101021

Manufacturing companies around the globe are striving to increase their revenues and profitability. One way is through Functional Sales, i.e. shifting the focus from the production of products to the production of services. Functional Sales and Design for Environment (DfE) have many common issues, e.g. the life cycle perspective. The paper’s aim is to highlight a proposed interactive design method for Service Engineering of Functional Sales offers and to relate this method to selected DfE methods and tools as well as users’ experiences with these methods and tools. The paper concludes that the proposed method has several benefits that are useful in DfE. One benefit is that the method does not focus on products but rather on how needs can be satisfied by increasing service content. Another is the visualization of e.g. validation in order to facilitate communication between different actors in the product development process.

For standardized environmental management systems (EMS) to be environmentally effective tools, they should affect important environmental aspects related to flows of materials and energy, which for manufacturing companies are closely connected to their products. This paper presents how external environmental auditors interpret and apply important product-related requirements of ISO 14001 at manufacturing companies in Sweden. The results indicate that the link between EMS and products is rather weak. Products are seldom regarded as significant environmental aspects and are therefore not within the main scope of many EMS, which are mainly focused on sites. However, all of the interviewed auditors require that some kind of environmental considerations be incorporated into product development, but these considerations are to large extent site oriented; how they are prioritized in relation to other factors such as economics and other customer priorities appears to be up to the companies. The paper includes some recommendations to strengthen the role of products within the framework of standardized EMS.

Humanity's activities increasingly threaten Earth's richness of life, of which mankind is a part. As part of the response, the environmentally conscious attempt to engineer products, processes and systems that interact harmoniously with the living world. Current environmental design guidance draws upon a wealth of experiences with the products of engineering that damaged humanity's environment. Efforts to create such guidelines inductively attempt to tease right action from examination of past mistakes. Unfortunately, avoidance of past errors cannot guarantee environmentally sustainable designs in the future. One needs to examine and understand an example of an environmentally sustainable, complex, multi-scale system to engineer designs with similar characteristics. This dissertation benchmarks and evaluates the efficacy of guidance from one such environmentally sustainable system resting at humanity's doorstep - the biosphere. Taking a holistic view of biomimicry, emulation of and inspiration by life, this work extracts overarching principles of life from academic life science literature using a sociological technique known as constant comparative method. It translates these principles into bio-inspired sustainable engineering guidelines. During this process, it identifies physically rooted measures and metrics that link guidelines to engineering applications. Qualitative validation for principles and guidelines takes the form of review by biology experts and comparison with existing environmentally benign design and manufacturing guidelines. Three select bio-inspired guidelines at three different organizational scales of engineering interest are quantitatively validated. Physical experiments with self-cleaning surfaces quantify the potential environmental benefits generated by applying the first, sub-product scale guideline. An interpretation of a metabolically rooted guideline applied at the product / organism organizational scale is shown to correlate with existing environmental metrics and predict a sustainability threshold. Finally, design of a carpet recycling network illustrates the quantitative environmental benefits one reaps by applying the third, multi-facility scale bio-inspired sustainability guideline. Taken as a whole, this work contributes (1) a set of biologically inspired sustainability principles for engineering, (2) a translation of these principles into measures applicable to design, (3) examples demonstrating a new, holistic form of biomimicry and (4) a deductive, novel approach to environmentally benign engineering. Life, the collection of processes that tamed and maintained themselves on planet Earth's once hostile surface, long ago confronted and solved the fundamental problems facing all organisms. Through this work, it is hoped that humanity has taken one small step toward self-mastery, thus drawing closer to a solution to the latest problem facing all organisms.

In the recent years, more and more manufacturing firms recognize the benefit of providing products together with related services with an aim to gain higher profits as compared to supplying products without additional services. On the other hand, the competition in the global markets has been increased dramatically through increased sales of services in order to gain additional value for their products. In addition, several environmental challenges such as climate change, pollution, global warming impact, greenhouse gases emissions have played a vital role by influencing on the production protocols and trend of the companies. These challenges forced manufacturing countries to take into consideration environmentally conscious approach to their design thinking and industrial production processes. As a result, it became an important drive for manufacturing industries to shift from traditional product-oriented to service-oriented business models that has been witnessed during the last few years.   The objective of this study research is to develop common questions that capture fundamental and common issues about Integrated Product Service Engineering (IPSE), Design for Environment (DFE) and Engineering education are effectives for industries to check and develop their knowledge, because the Engineering education plays a necessary role in associating socio-ethical knowledge with scientific and technological advances. The strategy taken to conduct this thesis task was first to study and understand the concept of Product Service System (PSS), IPSE, and Ecodesign as well as Engineering Education. Informative knowledge on these concepts were collected by reviewing several related journal articles, CIRP IPS2 conference proceedings.   In this thesis the concepts of PSS, IPSE, DFE and Engineering Education discussed to develop the key common questions and issues to address the environmental, economic and social problems. Since PSS aims to reduce consumption through alternative schemes of product use as well as to increase overall resource productivity and dematerialization, but IPSE does not focus on a single factor but incorporates a wide range of factors such as environmental, social and economic issues. Whilst one of the main problems in this research focused on how to develop and strengthen the relationship between the academia and industry, and how this relation can be used to improve the academic performance and scientific research at universities and transfer them to industry.   Sustainability and the life cycle concept have become a main solution for various problems such as a growing world population and a change in the industrial culture to come. As results Ecodesign and environmental considerations, financial aspects, product improvement as well as the commercial aspects were discussed in this project by understanding the previous concepts. The university considered as an important base of cultivating the talents, basic of inputs business organizations which help them to develop and improve their level of performance and quality of their products and services, and enhance its competitive position in the market. Changes in organized science further encouraged university interests in expanding technology transfer, because the scientific disciplines play an important role in influencing the type of interactions with industry as well as the University and Industry collaboration became the basic method of solving the problems to achieve (environmental, economic and social) sustainability.

Probabilistic graphical models (PGMs) provide the capability of evaluating uncertainty and variability of product use in addition to correlating the results with aspects of the usage context. Although energy consumption during use can cause a majority of a product's environmental impact, common practice is to neglect operational variability in life cycle inventories (LCIs). Therefore, the relationship between a product's usage context and its environmental performance is rarely considered in design evaluations. This dissertation demonstrates a method for describing the usage context as a set of factors and representing the usage context through a PGM. The application to LCIs is demonstrated through the use of a lightweight vehicle design example. Although replacing steel vehicle parts with aluminum parts reduces the weight and can increase fuel economy, the energy invested in production of aluminum parts is much larger than that of steel parts. The tradeoff between energy investment and fuel savings is highly dependent upon the vehicle fuel economy and lifetime mileage. The demonstration PGM is constructed from relating factors such as driver behavior, alternative driving schedules, and residential density with local conditional probability distributions derived from publicly available data sources. Unique scenarios are then assembled from sets of conditions on these factors to provide insight for sources of variance. The vehicle example demonstrated that implementation of realistic usage scenarios via a PGM can provide a much higher fidelity investigation of energy savings during use and that distinct scenarios can have significantly different implications for the effectiveness of lightweight vehicle designs. Scenarios with large families, for example, yield high energy savings, especially if the vehicle is used for commuting or stop-and-go traffic conditions. Scenarios of small families and efficient driving schedules yield lower energy savings for lightweight vehicle designs. / text

This thesis aims to discover possibilities of using products that mechanically transform to support environmentally significant behaviour (ESB), a term that refers to intentional behaviour of an individual to change the natural world. The first half of the work explored the potential relationship between mechanical transformation principles and certain ESBs. This exploration found that implementing transformative mechanisms in products enabled spontaneous use of the products in unanticipated situations. For example, a collapsible reusable shopping bag helped users avoid purchasing disposable bags when they went to grocery stores impulsively. The second half studied a variety of organisms to identify transformation patterns in nature. These patterns were summarized in a two-dimensional matrix to facilitate conceptual design of transformable products. In summary, this work showed that mechanical transformation facilitates at least three types of ESB, and also developed a new tool to assist designers in developing conceptual transformable products that can support ESBs.
