This memory aid covers Memory Aids within Life Cycle Assessment for GCSE Chemistry. Revise Life Cycle Assessment in Using Resources for GCSE Chemistry with 22 exam-style questions and 12 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 14 of 17 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 Memory Aids
The 4 stages of LCA — RMUE:
"RMUE through the lifecycle"
- Raw material extraction — mining, drilling, harvesting
- Manufacturing — converting raw materials into the product
- Use phase — energy consumed during the product's life
- End of life — disposal, recycling, or incineration
Cradle to Grave visual memory: Picture a baby's cradle (birth = raw materials from the earth) and a gravestone (death = disposal back to the earth). Everything that happens in between is the LCA.
LCA limitations — DISC:
- Data quality issues — incomplete supply chain data
- Impact comparison difficulty — how to compare CO₂ vs habitat loss?
- Subjective boundaries — what counts as "inside" the assessment?
- Commercial bias — companies may cherry-pick favourable data
