TL;DR: In this paper, a general methodological framework for assessing the environmental impacts of products is proposed and two components of the methodological framework, the goal definition and the inventory, are discussed in more detail.

TL;DR: In this article, a methodological framework for life cycle assessment (LCA) was proposed and two components of this framework were discussed in more detail: the goal definition and the inventory, and two complementary techniques for the identification of the potential options for the redesign of a product were discussed.

TL;DR: In this article, the authors explore the practical application of life cycle assessment (LCA) to product system development, and present an overview of several design initiatives based on the life cycle framework.

TL;DR: In this paper, the authors discuss a number of points in the life cycle inventory methodology (choice of product alternatives, geographical system boundaries, technological levels and co-product allocation rules) where the market aspect becomes obvious and where a disregard for these aspects may lead to serious flaws in the results.

TL;DR: In this article, an overview is given of present applications of life cycle assessment (LCA) as an instrument for the support of decision-making, focusing on original expectations, present drawbacks and future perspectives.

TL;DR: In this article, the engine is controlled to suppress the amount of intake air by controlling an air control valve for a predetermined time after starting of the engine, then gradually increased until the engine generates a rating output.

TL;DR: In this article, carbon dioxide in the non-condensable gases substantially dissolves in the geothermal liquid cooled by the cooled steam condensate reducing the pH of the effluent and thus reducing mineral scale precipitation.

TL;DR: A cementitious concrete made from recycled plastics, portland cement, and sand/gravel fillers performs to the standards of concretes made without plastics as discussed by the authors, removing the previously time and resource intensive step of sorting and melting down constituent plastics from each other in the waste stream.

TL;DR: In this article, the authors present the next few years will be extremely important to the development of LCA as a fully recognized analytical tool, and the appropriate balance between profuse or inadequate information will also need to be set.

TL;DR: In this article, the authors described a recyclingable carpet floor covering comprising a backing, a tied-in pile yarn and a back finish with or without a secondary backing adhered to the primary backing.

TL;DR: In this article, the authors identify some of the practical difficulties in carrying LCA through to ecolabel criteria, and summarizes some solutions being adopted, including definition of the functional unit, definition of ‘cradle’ and ‘grave’ in the context of different disposal and recycling practices throughout the European community, sourcing of raw materials, and validation of imported goods.

TL;DR: A sound barrier panel as discussed by the authors consists of an acoustic layer that comprises chipped rubber and cord fiber from tires and a structural concrete layer bonded to the acoustic layer by a combination composite bond that includes both a mechanical portion and a chemical portion.

TL;DR: The format of the database is governed by the physical requirements of the system being examined, by the need to include iterative calculations within the analysis and by the demands of the final data presentation.

TL;DR: In this paper, the authors examined the synergetic relations between green products, their production and related consumption patterns to set out a course of action for a better and sustainable environment.

TL;DR: In this paper, the authors conducted a waste prevention assessment at a foundry and used this case study to elaborate on the success factors that should be borne in mind if one wishes to initiate a system of continuous environmental improvement.

TL;DR: The concept of environmental merit as mentioned in this paper is a theoretical framework for a methodical approach to integrated life cycle management at the company level, which aims to make systematic contributions to reducing the loss of environmental reserves in terms of environment-polluting substances and scarce natural resources.

TL;DR: In this article, issues related to the collection, assembly and interpretation of data on the consumption of energy, and emissions generated, during the process of plastics manufacture are discussed, and a comparison between the new data sets produced by the plastics industry and historical data published by BUWAL is given.

TL;DR: A cyanide recovery circuit was proposed in this paper to enable leaching to be conducted at a pH of around 9 instead of the conventional 10.5, with a consequential halving in consumption of pH modifying reagents.

TL;DR: The influence of the development of software on both data and methodology is addressed and illustrated by examples, with reference to two key terms: transparency and explicitness.

TL;DR: In this paper, the US Environmental Protection Agency in cooperation with the State of New Jersey evaluated chemical filtration and distillation technologies designed to recycle automotive and heavy-duty engine coolants.

TL;DR: The first edition of The LCA Sourcebook was published by SustainAbility Ltd as discussed by the authors, who contacted 120 European non-governmental organizations (NGOs) likely to be involved in life cycle analysis (LCA) work.

TL;DR: In this article, the Association of Fish Meal and Fish Oil Manufacturers of Denmark had a detailed research assignment carried out, with the aim of determining the best available technology for reducing the pollution.
