Investigation of Manufacturing of Engine Group of ?Activa?: Assessment of Environmental Impact Evaluation

Every human activity has an impact on the environment in the form of emissions. The environment has some capacity to absorb these emissions so emitted to a certain level without lasting the damage. The manufacturing of a product produces emissions which may be detrimental to air, water and soil, during its entire life beginning from raw material extraction, manufacturing, assembly, transportation, usage to its final disposal. These emissions have harmful effect at local, regional and global levels. In order to have environment friendly engineering product, it is necessary to control the data which has prominent environmental impact during the various stages throughout its life cycle. It is important to identify processes and ingredients, which are major contributors to environmental impacts. Life cycle assessment (LCA) involves the evaluation of the environmental aspects of a product system through all stages of its life cycle. The primary objective of this work is to perform the investigations of manufacturing of Engine group of product Activa for quantitative evaluation of its environmental impacts for various impact categories under cradle-to-gate variant using Life Cycle Assessment (LCA) approach as per ISO14040. It has been carried out using the designed & developed software SSLCASoft. The results presents the cumulative environmental impact of Engine Group of Activa on various impact categories of EDIP-03. The major portion Engine Group of Activa having aluminium parts and the steel parts. The materialwise results show that the impact of steel parts is dominating. Subassembly-wise, the impact of Crank Shaft Piston (CSP) and Cam Shaft Valve (CSV) is prominent amongst all other subassemblies of Engine Group for steel parts. Looking to the results, there is a major scope of improving the environmental impact arises during the manufacturing life of Engine Group of Activa at the design stage.
