2 characteristics of sustainable materials Ans✓✓✓1. Provide beneficial
service while causing no permanent environmental degradation nor
cause adverse life conditions during their extraction, production, use or
disposal.
2. Can return to a harmless natural state at the completion of their useful
life or can be 100% recycled into other useable goods.
4 Stages of LCA Ans✓✓✓1. LCA Planning
2. Inventory Quantification (aka LCI)
3. Evaluation (aka LCIA)
4. Interpretation
Layout a process tree for each component that makes up the product.
Ans✓✓✓1. Input Flow - what material(s) go into the process
2. Type of Process (Process Output)
3. Output Flow - what comes out of the process
5 Steps in Evaluation in LCA Ans✓✓✓1. Selection - identifying
environmental impacts.
2. Classification - assigning outputs to impact categories.
, 3. Characterization - modelling outputs with impact categories based on
scientific conversion factor.
4. Normalization - dividing the values by a selected reference quantity to
increase comparability.
5. Weighting (optional) - assigning subjective weighting factors to the
impact categories based on perceived importance.
