2. Life Cycle Inventory:
Introduction: Every new product or development made by man has an impact on environment. Growing environmental concerns has made it necessary to quantitatively study these factors. Life cycle assessment (LCA) is one such tool devised for calculating the overall environmental impact of a product or service. It includes defining aim and scope of assessment, inventory analysis, impact assessment and deriving conclusions. Life cycle inventory (LCI) is a part of LCA and involves direct collection of input output data from the system. Quantities like material/resource consumed, energy utilised fall under inputs while energy and by-products released are considered outputs. Life cycle impact analysis (LCIA) consists of

Introduction: Every new product or development made by man has an impact on environment. Growing environmental concerns has made it necessary to quantitatively study these factors. Life cycle assessment (LCA) is one such tool devised for calculating the overall environmental impact of a product or service. It includes defining aim and scope of assessment, inventory analysis, impact assessment and deriving conclusions. Life cycle inventory (LCI) is a part of LCA and involves direct collection of input output data from the system. Quantities like material/resource consumed, energy utilised fall under inputs while energy and by-products released are considered outputs. Life cycle impact analysis (LCIA) consists of derived conclusions from study of life cycle inventory. E.g. LCI for laptop would involve resources consumed and by products emitted during recycling. LCIA would define the effect on global warming due to these by products.
Scope of study: A company catering department has decided to replace expanded polystyrene (EPS) cups with paper cups. This report compares both the materials in terms of their effect on environment. As paper by itself cannot be used to hold hot drinks, it is considered that paper cups are made of either PE coated or wax coated paper. The cups are compared without lid, assuming the lid if used, be made of polystyrene. Performing actual survey or experimentation work was not possible, the study was conducted using
