Live divert-versus-reduce board — so a high recycling rate never pretends to shrink the pile.

01
Households often celebrate a high recycling rate while the trash can still feels heavy. Diversion redistributes what you generate; source reduction shrinks the pile before those rates apply. The same 60% diversion on 40 kg/week leaves more landfill kilograms than 60% diversion after you cut the pile by a quarter.
This page’s framing is Divert ≠ reduce. The board compares residual landfill under divert-only versus your reduce-then-divert path — so rate pride never pretends to be hierarchy literacy. A green bin sticker is not a smaller pile.
That is a different job from carbon footprint (Inventory ≠ lever across lifestyle categories) and carbon offset (offset ≠ cut for residual tons). Here we stay inside the waste hierarchy — not a whole-life inventory and not a purchase of offsets.
Decision framing: “Did I shrink the pile — or only redirect streams of the same pile?”
02
The unique affordance is the twin residual readout: landfill kilograms if your recycle/compost rates ran with zero source reduction, versus landfill after your reduce %. The residual gap is how much reduce-first buys versus divert-only pride.
Flip Divert-proud → Reduce-first with the same rates. Diversion rate can look similar while landfill kilograms drop — Divert ≠ reduce made visible, not a lifestyle category stack and not a $/ton offset ladder. Residual mass is the honesty metric; rate alone is the vanity metric.
03
Enter source reduce % first. Recycle and compost percents apply to what remains. That order matches the classic hierarchy: prevent generation, then divert organics and recyclables, then landfill residual. Buying less packaging and fixing leaks of “free” clutter lives in reduce — not in a higher recycle slider.
If recycle + compost exceed 100% of remaining, the sketch renormalizes and flags overlap chaos — rates cannot both be literal shares of the same pile. Fix the shares before quoting a diversion rate to anyone.
Keep weekly kg and divert rates fixed. Raise source reduce 0% → 25% and watch only the residual gap — that is the product.
04
Recycle, compost, and landfill rails show kilograms and share of the post-reduce pile. Diversion rate is diverted ÷ after-reduce — honest to the hierarchy, not to an unchanged gross pile with double-counted percents.
CO₂e avoided is an indicative proxy versus an all-landfill baseline on the original weekly kg. Material-specific WARM runs belong elsewhere; this board owns Divert ≠ reduce, not a full LCA. Use the stack to see whether organics or recyclables actually move mass — then decide where habit change pays.
05
Source reduction shrinks the pile. Divert rates (renormalized if overlapping) split the remainder. Residual gap contrasts divert-only landfill with your path.
Indicative factors: landfill ~0.79, recycle ~0.15, compost ~0.05 kg CO₂e per kg — educational averages, not EPA WARM material tables.
06
After Divert ≠ reduce, hand off for whole-lifestyle inventory, residual offset purchases, home energy Bill ≠ footprint, or water use.
07
Scenario A — Divert-proud. High recycle/compost, zero reduce. Diversion rate looks excellent; residual landfill on a 40 kg pile stays material. Divert ≠ reduce warns: rate ≠ residual.
Switch to Reduce-first without changing divert rates. Watch landfill and residual gap — same rates, smaller pile.
Scenario B — Reduce-first. Reduce-led narrative: cutting generation beats divert-only on residual kilograms even when the diversion percentage looks similar.
Scenario C — Overlap rates. Recycle + compost > 100. Chaos chip + renormalize — fix the shares before claiming a diversion rate.
Scenario D — Compost-led. Organics divert with modest recycle. Stream stack shows where kilograms actually go after reduce — hierarchy clarity without a full footprint inventory.

Stop here for waste hierarchy literacy. Hand off for lifestyle inventory, offsets, home energy, or water.

Diversion rates (recycling and composting as a share of what remains) redistribute streams. Source reduction shrinks the pile before those rates apply. The same 60% diversion on a large pile can leave more landfill kilograms than a smaller pile with the same rates — Divert ≠ reduce.
We compute landfill under your divert rates with zero source reduction, then landfill after your reduce % with the same rates. The kilogram difference is residual gap — how much reduce-first cuts landfill versus divert-only pride.
That is overlap chaos: the rates cannot both be true shares of the same remaining pile. The sketch renormalizes them to 100% and flags the chip so you fix the inputs.
No. They are indicative mixed-waste factors for education (landfill vs recycle vs compost processing). Material-specific impacts belong in tools like EPA WARM — not this household hierarchy board.
Carbon footprint owns Inventory ≠ lever across lifestyle categories. This page owns Divert ≠ reduce inside the waste hierarchy: source cut versus diversion rates and residual landfill.
Offset ≠ cut buys residual tons after avoidance. Waste reduction asks whether you shrank the pile or only redirected streams — not whether to purchase offsets.
The hierarchy puts reduce first. High diversion on an unchanged pile can look green while landfill kilograms stay large — that is the Divert ≠ reduce lesson on the residual board.
