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.
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.
Concentration rising steadily over days. Worth a human look, not yet an emergency.
Could be a real event or a faulty sensor. Needs a second reading or a field check before acting.
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.
The same pipeline runs every few minutes, all day, so nothing waits for the next scheduled inspection.
No single model makes a decision alone. Each component has one job.
Learns each sensor's seasonal baseline and predicts where the next reading should fall.
Turns a flagged anomaly into a plain-language advisory an officer can act on quickly.
Checks whether a similar pattern has occurred at this site before, and how it resolved.
Reads uploaded field photos for visible cracks, ponding, or cover damage near a flagged zone.
Produces a draft site diagram or briefing sheet to accompany a work order.
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.

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.
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."
