This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly. The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are: • Are there any other alternative asphalt coatings available? • Can bio-oils be used in asphalt? • If the bio-oils can be used, what are the details their properties? • How does a cold climate affect the bio binders? • What is the Swedish asphalt industry’s opinion about bio asphalt? The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews. The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas. The biggest problem for greater use is the fact that it is expensive and performance in cold climate is unknown. The study indicates that Sweden could have a new potential industry in the field of producing bio-adhesives from both wood and waste from paper industry

The purpose of the study was to assess 5th grade Turkish students&rsquo / environmental literacy (EL) level by considering six EL components, and explore the factors predicting the environmentally responsible behaviors (ERB) of these students. The research design of the study was nation-wide survey. The sample of the survey consisted of 2412 fifth grade students selected from 78 elementary schools (26 private and 52 public) in 26 provinces across Turkey. Developed by the researcher, Elementary School Environmental Literacy Instrument (ESELI) including five parts and total 81 items was used as data collection instrument. To analyze quantitative data, descriptive statistics, ANOVA, multiple correlation and path analysis were conducted. The responses to open-ended question were subjected to content analysis. The results of the study revealed that EL score of the students was found 149 (SD=26.19) suggesting moderate level of EL and 64.1% of the students (n=1545) had moderate level EL. The factors significantly affecting 5th grade students&rsquo / ERB and the effect size of these factors were as follows / school type (partial =.007), taking pre-school education (partial =.002), mother education level (partial =.007), father education level (partial =.012), residence (partial =.008), experiences in the natural regions (partial =.046), curiosity toward environmental information (partial =.048), mother environmental concern (partial =.023), father environmental concern (partial =.031) and sibling environmental concern (partial =.014). Furthermore, a combination of environmental knowledge, willingness to take environmental action, cognitive skills, and environmental attitude and environmental sensitivity explained 12% of the variance in ERB. As a conclusion, the results of the presents study will shed light on the attempts on policy making and curriculum development regarding environmental education.

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.

Dieser Beitrag gibt, basierend auf einem BMBF-Verbundvorhaben, Einblicke in die umfassende Bewertung von OPTextilien. Ziel des Vorhabens ist es, Entscheidern in Krankenhäusern Anregungen und Know-how für ihren Berufsalltag und Produzenten von OP-Textilien Impulse für die Gestaltung ihrer Produkte zu geben. Es werden die hygienischen Anforderungen zur Vermeidung nosokomialer Infektionen, die die Schutzwirkung der Textilien garantierenden textiltechnologischen Voraussetzungen sowie die zur Erfüllung der Wirtschaftlichkeit und Umweltfreundlichkeit notwendigen Anforderungen an OP-Textilien dargestellt. Der Beitrag verdeutlicht, dass die Beachtung all dieser Kriterien und deren Zusammenführung für eine bewusste Entscheidung zum Einsatz von OP-Textilien notwendig ist. / This article describes a holistic assessment approach for operating room (OR) textiles, based on a joint research project funded by the German Ministry of Education and Research. The objective of the project is to ease decision processes for decision makers in hospitals and OR textile manufacturers. The hygienic demands for protection against nosocominal infections, the technological requirements to guarantee textiles their protective properties, as well as the bases for an economically and environmentally optimum decision, are discussed. To permit a holistic procurement decision regarding OR textiles, it is necessary to consider all these criteria and their integration, as proposed in this article.

In an age of increased environmental awareness, environmental education in schools has become progressively valued and supported. With this in mind, the purpose of this study was to investigate the significance of art education within the context of environmental schools and other sites of environmental education. Specifically, this research aimed to identify ways art education is being used as a means to strengthen outdoor learning. Through qualitative research involving multiple case studies of the art programs of three environmental charter schools and one nature center in Pennsylvania, data was gathered by means of on-site observations and interviews with staff and students of the aforementioned sites. Although the findings of this study indicated that each of the sites incorporated some degree of art in their environmental curricula, the results demonstrated a significant deficiency in the presence and support of art education in the environmental education programs within each site. Based on the findings of this study, suggestions were made concerning ways art may be used as a means through which students might more closely examine and experience the natural environment. / text

Scientific evidence of human impact on the natural environment, such as global warming, continues to mount. Green manufacturing systems that focus on minimizing environmental impact of manufacturing processes and products are ever more important to our sustainable future. Green manufacturing systems are slow to gain acceptance as manufacturers are focused on implementing Lean manufacturing systems, generally considered the most competitive manufacturing systems in the world. In recent years, researchers and the US Environmental Protection Agency (EPA) have sought to "build a bridge" between Lean and Green manufacturing systems, in hopes that the rapid expanse of Lean can serve as a catalyst to the implementation of Green manufacturing systems.This study contributes to this growing body of knowledge by determining if leading Lean manufacturers are transcending beyond the traditional limits of Lean and implementing Green manufacturing systems as part of their overallwaste reduction strategy. In this work Lean manufacturing plants that have been evaluated by a panel of experts from the Shingo Prize for Excellence in Manufacturing are surveyed on the diffusion of Green manufacturing system practices throughout their operation. A full system correlation analysis is performed utilizing forty-eight measures of Lean and Green manufacturing systems under the categories of management system, waste reducing techniques, and results. Data analysis indicates that known Lean manufacturers are significantly Greener than the general population of manufacturers in twenty-five of twenty-six measures of Green manufacturing. Lean manufacturers who implement Green manufacturing systems have the strongest results in both Lean and Green result areas, particularly cost reduction, indicating synergy between Lean and Green manufacturing systems. Manufacturing plants that choose to vertically integrate versus horizontally integrate their Lean systems transcend to Green manufacturing. Mexican plants in the study practice significantly higher levels of material resource efficiency and are more inclined to develop industrial partnerships to resolve environmental issues. The study also identifies a critical need for integrating Lean and Green management systems to drive synergistic waste reducing techniques throughout the operation. An integrated Lean and Green manufacturing system model, dubbed "Zero Waste Manufacturing", is proposed as a solution for economically and environmentally sustainable manufacturing.

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.
