GENERAL KNOWLEDGE

Detailed explanation-1: -Life cycle analysis (LCA) is a method of quantifying the environmental impacts associated with a given product. In LCA, researchers create an inventory of resources used and pollutants generated in product production and use.

Detailed explanation-2: -LCA is an approach to study the environmental aspects and potential impacts throughout a product’s life from raw material acquisition or production (e.g. wood production in the forest) to manufacturing, use, recycling and disposal.

Detailed explanation-3: -It can be used to study the environmental impact of either a product or the function the product is designed to perform. LCA is commonly referred to as a “cradle-to-grave” analysis.

Detailed explanation-4: -The life cycle inventory (LCI) analysis is a technical process that quantifies all inputs to and outputs from the processes within the system boundaries. The inputs are energy and raw materials, and the outputs are emissions to air, water, and soil; solid waste generation; products; and co-products.

Detailed explanation-5: -Life cycle assessment considers both the direct and indirect impact of a process or technology in the upstream process value chain. Energy can be produced from a variety of fuels or renewable sources. Thermal energy is delivered in the form of heat and the heat is often used to generate electricity or power.
