The 3 Rs in order of priority (most to least impactful):
Reduce → Reuse → Recycle
"You should always try to REDUCE what you use first. If you can't reduce, REUSE what you have. Only RECYCLE when the other two aren't possible."
Energy savings mnemonic — "ASPG" (metals in order of energy saving):
- Aluminium — 95% energy saving (best recycler)
- Steel — 60% energy saving
- Paper — 40% energy saving
- Glass — 30% energy saving (least, but still valuable)
Remember landfill produces METHANE (a greenhouse gas): "Buried rubbish + bacteria = methane gas underground." Methane is approximately 25 times more potent as a greenhouse gas than CO₂ over 100 years.
