How ClearPath thinks

ClearPath turns a resident's question ("where does this battery go?") into a verdict with citations in under 10 seconds. Six rule layers contribute to every answer, and the same five-step pipeline runs for every item, from an AA battery to a commercial refrigerator. Every step is auditable. Every step is sourced. Every decision shows its reasoning.

How the answer gets built

Six layers contribute to every answer.

No single AI model decides what you should do with your waste. Six different rule layers contribute to each answer. You can see what each one did and where its information came from. Here is what each layer does.

Layered authority composition

Federal → State → County → City. Every verdict shows which authority level produced which step, with the source URL and the date it was last verified.

Evidence
Example: a mercury thermometer shows four authorities — federal, state, county, and a local facility — for a single item.

Conditional rule resolver

When a city rule depends on item state ("Is the chair still usable?"), you get one quick question. Tap an answer, and the verdict resolves on the same page.

Evidence
Example: Richfield’s chair rule asks usable vs. broken, then routes to donation or special pickup.

Contamination prevention

Routes hazardous items (lithium batteries, sharps, e-waste) away from the trash bag before you commit. Operators see a dashboard of the ZIPs where confusion clusters.

Evidence
Resident sees the warning before disposal; the operator dashboard surfaces patterns by ZIP.

Before-You-Throw circular redirect

When an item is reuse-eligible and a verified donation or take-back option is nearby, you see that first. It is never forced. You always see both options.

Evidence
Active for Hennepin County · 28 manufacturer take-back programs catalog-wide.

Smart pickup decision

Looks at item size, hazard, condition, and pricing in one pass. You only see "Request pickup" when a hauler can actually fetch the item. Haulers see whether each pickup is donation, drop-off, or hazard.

Evidence
Residents see eligibility before scheduling; haulers see the path on the job card.

Rule conflict intelligence

When two sources disagree in the same scope ("Compost in one city, trash in the next"), the engine names the conflict and picks based on your ZIP. Operators get a one-click way to resolve it.

Evidence
Resident sees both sources side-by-side; the operator dashboard offers one-click resolution.

Two more layers run on the operator side: illegal-dumping early warning and service assurance. Eight in all.

How a question becomes an answer

Five steps, every time. No shortcuts.

Every resident verdict runs through the same path. Same engine for "AA battery" as for "old refrigerator." No black-box AI deciding silently. Every step is auditable, sourced, and named.

  1. 01

    Resident scans or types the item

    Photo, short text, or voice. The vision system identifies the item, the material, and any hazard cues. If your local rule depends on condition ("Is the chair still usable?"), it asks one clarifying question.

    What you see
    On your screen: a quick scan or one-line input.
  2. 02

    Engine identifies and normalizes the item

    Once matched, the item carries its category, hazard level, and known aliases. That way "laptop battery" and "li-ion 18650" both route to the same Federal Universal Waste rule.

    What you see
    On your screen: "Likely: Lithium-ion battery" with the confidence tier.
  3. 03

    Federal → State → County → City rules combine into the verdict

    The selector walks Federal down to City. The most specific applicable rule wins, but the verdict shows every layer that contributed, with each source URL.

    What you see
    On your screen: a stacked authority chain you can expand to see each layer.
  4. 04

    Trust chain verifies the answer

    Every cited URL is checked daily. Stale citations show as warnings. Verified ones get a "last verified" date on the verdict. If two sources at the same scope disagree, we flag the conflict instead of hiding it.

    What you see
    On your screen: a "verified this week" badge and a clickable list of sources.
  5. 05

    You see the exact next action

    You get a specific recommended path: bin, drop-off, take-back program, or pickup. It comes with the prep steps, the facility (if any) with hours and distance, and a "request pickup" button only when a hauler can actually fetch the item.

    What you see
    On your screen: a verdict card you can act on in one tap.

The same five steps run for every ZIP we cover. 3,222 of them today.
