A product of Interbot, built for municipal landfills

Know a methane breach is coming — while there's still time to stop it.

Landfill Sentinel reads continuous methane sensor feeds, weather data, and site inspection notes from your landfill and turns them into ranked advisories and draft work orders that a qualified officer reviews and signs off before anything is issued. No sensor reading becomes an action without a human in the loop.

SENSOR-TO-REVIEW CYCLE

Methane builds quietly until it isn't quiet anymore

Most South African landfills are only inspected periodically. Between visits, gas concentrations can drift well past safe thresholds without anyone noticing until there's a smell complaint, a fire, or a compliance notice.

Incident or breachodour complaint, fire risk, or non-compliance notice
MODEL FLAGS — LEAD ONLY

Gradual drift above baseline

Concentration rising steadily over days. Worth a human look, not yet an emergency.

WATCH — AWAITING CONTEXT

Sudden spike, single sensor

Could be a real event or a faulty sensor. Needs a second reading or a field check before acting.

ESCALATE — TIME SENSITIVE

Multiple sensors, sustained rise

Pattern consistent with a real subsurface event near a threshold. Routed for priority human review.

Every output from Landfill Sentinel is a lead for a qualified reviewer to weigh — never a certified environmental determination.

From a sensor reading to a signed-off work order

The same pipeline runs every few minutes, all day, so nothing waits for the next scheduled inspection.

Every stage of the intelligence layer, named plainly

No single model makes a decision alone. Each component has one job.

FORECAST

Forecasting model

Learns each sensor's seasonal baseline and predicts where the next reading should fall.

DRAFT

Advisory-generation LLM

Turns a flagged anomaly into a plain-language advisory an officer can act on quickly.

CONTEXT

Historical-pattern LLM

Checks whether a similar pattern has occurred at this site before, and how it resolved.

VISION

Vision LLM

Reads uploaded field photos for visible cracks, ponding, or cover damage near a flagged zone.

ASSET

Generative-asset model

Produces a draft site diagram or briefing sheet to accompany a work order.

REQUIRED

Human review — required

A qualified officer approves, modifies, rejects, or escalates every recommendation before it becomes an action.

Model names shown throughout this site are illustrative; specific provider and model choices should always be verified against current provider documentation before deployment. In this build, all AI outputs are simulated to demonstrate the shape of the workflow — no live model calls are made. Any cost figures referenced are labelled estimate ranges, not quotes, and should be confirmed with providers directly.

The monitoring loop, in three dimensions

Drag to rotate. Move the slider to see how a rising methane reading changes what happens next.

CH₄ concentration (stress variable)450 ppm
NORMAL
Readings are within the expected range for this site — the model keeps watching quietly in the background.
WHAT YOU'RE LOOKING AT
  • 1The flat plane is the landfill's active waste cell.
  • 2The pulsing amber node is the sensor reading gas concentration.
  • 3The teal node above it is the AI pipeline processing that reading.
  • 4The dashed line from AI to the top node is the advisory reaching a human reviewer.
  • 5The small moving sphere is a field inspector — watch how its path changes when the slider crosses the threshold.

Why continuous monitoring matters here

Landfill gas is a real and measured problem at South African sites — not a hypothetical one. Here's the pipeline again, explained the way you'd explain it to a curious ten-year-old, alongside the evidence behind it.

SensorsLittle machines in the ground that sniff for gas, all day, so nobody has to go check by hand every time.
Forecasting modelA computer that remembers what "normal" looks like for this landfill, so it notices when something looks off.
Advisory LLMTurns confusing numbers into a short note a person can actually read and understand fast.
Human reviewA real person double-checks the computer's guess before anyone acts on it — the computer never gets the final word.

Deployment & coverage zones

Weather conditions below are fetched live from Open-Meteo's free public API for each real landfill location. The deployment stage label is Landfill Sentinel's own internal designation and is not derived from this live feed.

"A landfill doesn't send a warning before it becomes a health hazard — so we built the warning ourselves. Every family living near a South African landfill deserves a municipality that sees a problem coming, not one that reads about it after the fact. That's what success looks like for us: fewer emergencies, fewer breaches, and communities who never have to find out the hard way that no one was watching."

"See it before it's a crisis."
