Item Use of dfe methodologies and tools - Major barriers and challenges(ICED, 2007) Kota, SrinivasProducts make substantial impact on environment. Product to waste mass generated through out the product lifecycle can be as high as 1:20. Design for Environment (DfE) is an approach to design where all the environmental impacts of a product are considered over the entire life cycle of a product. Early stages of product development are the key for this because if we know the environmental impacts of potential designs while designing, we can make changes to these designs then and there so as to reduce their environmental impacts [1, 2]. However, unlike cost and performance, use of environmental criteria and DfE is far from part of mainstream designing [3]. Most DfE tools are conceptual in nature, and there is very little adoption of these in industry. Methods like [4] are useful for specific phases of the lifecycle of a product. However, during product development there is a need to consider the whole lifecycle rather than a single phase of the productItem Development of a platform for supporting design for environment(ICED, 2007) Kota, SrinivasIndividual guidelines often exist for DfE but these are not integrated with design tools. There is no comprehensive method that can be useful for the whole life cycle of a product in various stages of its design. Few tools exist that could aid iterative changes to a design required in product development and there is a need for an integrated methodology and computational support for designers. Life Cycle Assessment (LCA) [1] is arguably the most promising and scientifically defendable method for estimating environmental impacts of a product during its lifecycle [2]. Like DfE guidelines, LCA tools are not well integrated with design process and tools. Consequently, there is a need for an LCA tool integrated into the natural design process that can be applied to early as well as detailed design stagesItem ACLODS – A Holistic Framework for Environmentally Friendly Product Lifecycle Design(Springer, 2021-01) Kota, SrinivasDesign for Environment (DfE) is an approach to design where all the environmental impacts of a product are considered over the entire life cycle of a product. Most DfE tools are conceptual in nature, and there is little adoption of these in industry. This chapter discusses the development of a holistic framework that should help in both generation and evaluation of environmentally friendly product life cycle proposals. The overall approach is to investigate literature to analyse the existing guidelines, methods, tools and methodologies for environmentally friendly product design, in order to identify the requirements for a holistic framework for design to reduce the environmental impact of a product lifecycle proposal. An ideal framework to satisfy these requirements is proposed.
