Solid Waste Monitoring

Using multispectral and thermal satellite imagery to track landfill volumes, informal dump growth, and collection-route compliance across municipal areas.

Municipal waste authorities operate largely blind between ground inspections. Landfills expand incrementally, informal settlements generate waste faster than rosters can track, and collection contractors self-report compliance with little verification. A city running on spreadsheets and monthly site visits cannot catch a landfill approaching capacity until the crisis is already visible from the road.

A small constellation of multispectral microsatellites, revisiting each city every two to three days, changes the economics of oversight entirely. Thermal infrared channels detect subsurface combustion and methane hotspots at active landfill faces. High-resolution visible and near-infrared bands quantify surface-area growth to sub-hectare precision. RF-tagged collection vehicles optionally feed into the same ground pipeline, fusing space and terrestrial data into a single operational picture for waste management directors.

The operational outcome is evidence-based contract management and early warning on environmental breaches before regulators impose fines or communities organise opposition. A sovereign constellation serves every municipality in the country from a single tasking queue, replacing a patchwork of vendor contracts that each city currently negotiates separately and that evaporate the moment a commercial provider reprices or exits the market.

What matters

Landfill methane is a potent short-lived climate pollutant; satellite thermal detection identifies hotspots weeks before ground inspectors would reach them.
Commercial satellite tasking contracts typically exclude sub-daily revisit and raw-data access, making independent audit of contractor performance legally and technically impossible.
Waste collection non-compliance in low-income urban zones correlates directly with cholera and dengue outbreaks; satellite evidence triggers intervention before epidemiological thresholds are crossed.
A single national constellation can simultaneously monitor every municipality at a per-city cost an order of magnitude below individually procured vendor imagery subscriptions.

Sovereignty score: 7/10 — A government that relies on commercial imagery vendors to verify its own contractors' waste-collection performance has surrendered the evidentiary independence on which public-health enforcement and environmental compliance depend.

Contractor audit dependency: waste collection and landfill operation are typically outsourced; independent satellite evidence is the only leverage a city has when a contractor disputes compliance records.
Data continuity risk: a commercial vendor repricing, merging or exiting the market mid-contract leaves the authority with no baseline imagery for legal proceedings or environmental-damage claims.
Cross-border methane accounting: national greenhouse-gas inventories submitted under UNFCCC obligations include landfill emissions; sovereign monitoring produces defensible, independently audited figures rather than contractor estimates.
Public-health enforcement: thermal and spectral anomaly data showing illegal burning or leachate migration must be available to national health and environmental regulators without third-party licensing restrictions that delay or block disclosure.

Reference architecture

Payload: Multispectral imager covering visible, NIR and SWIR bands at 3-5 metre GSD; thermal infrared channel at 30-70 metre resolution for landfill combustion and methane-proxy heat mapping; 20 km swath minimum for efficient urban-area strip collection
Bus class: 16U cubesat or 40-80 kg microsatellite, 150-250W payload power; COTS thermal imager (e.g. Exolaunch-compatible OEM modules) integrated with multispectral camera on a shared optical bench
Orbit: Sun-synchronous LEO at 500-550 km; 12-satellite walker constellation delivers 2-3 day revisit globally; morning overpass preferred (09:00-10:30 local solar time) to minimise thermal noise before midday heating
Ground segment: National ground station network, minimum 2 X-band downlink sites for redundancy; TT&C via S-band; optional SatNOGS UHF/VHF beacon monitoring for housekeeping; data archived on sovereign cloud infrastructure, not vendor-managed storage
