Waste bunker management runs on one number that the crane operator, the boiler and the logistics office all need: current volume per zone. Yet in most waste-to-energy and EBS plants the firing crew or the crane operator still estimates fill level by eye from the control-room window. Which sector is oldest? Where is the crane right now — how much did it take from where, and where did it put it? Is the waste properly mixed? The answer lives in the operator's head — and walks out with every shift change.

OWL EYE® waste bunker monitoring replaces that estimate with a continuous 3D model of the entire bunker — sector-by-sector bunker volume measurement for waste incineration plants. The system delivers real-time crane tracking — live position and every move of the waste-crane grab — and knows volume per sector and age per zone (FIFO indicator). Cut-and-fill diffs show what was removed by the firing line and what was added by deliveries — per sector, per shift, per furnace line.

Built on the same engine as our OWL EYE® STOCKPILE volumetric platform, with a feed-bunker variant for shredded RDF and SRF on the recycling line.

„A firing crew that can read the bunker the way it reads the furnace makes better mixing decisions every single shift."

How waste bunker level measurement works

How does waste bunker level measurement work? Wie funktioniert die Füllstandsmessung im Müllbunker? Jak działa pomiar poziomu w bunkrze odpadów? Come funziona la misura di livello nella fossa rifiuti? Comment fonctionne la mesure de niveau dans la fosse à déchets ? ¿Cómo funciona la medición de nivel en el foso de residuos? Como funciona a medição de nível no bunker de resíduos?

Step 1 — scan. 3D-LiDAR sensors mounted above the bunker sweep the entire waste surface and return a dense point cloud — through the dust and steam that hang over every tipping hall. The crane and grab cross the field of view constantly; the system tracks them and masks them out automatically, so crane traffic never corrupts the surface model. One honest caveat: under permanent extreme dust directly above the discharge point, any optical method reaches its limits — sensor placement decides, which is why it is engineered individually for each bunker.

Step 2 — compute. The software registers every point cloud against the stored bunker geometry and converts it into volume per zone: cut-and-fill differentials show what was removed and where deliveries landed, zone age flags the oldest material (FIFO), and the movement history shows how well the waste has been mixed through.

Step 3 — deliver. The values feed the crane control system and the control room: grab recommendations for the next pick, a filling strategy for incoming deliveries, and throughput per zone and shift for the operations log.

3D bunker model

A continuous 3D surface of the entire bunker, segmented by sector. Per-sector volume, free capacity and zone age (FIFO indicator) replace the operator-eye estimate — the firing crew mixes from a real map, not from memory.

Crane grab tracking

Live grab position from the crane PLC API or derived directly from the LiDAR scan. What the grab picks up, where it drops, and which sector lost or gained volume — every cycle. The movement picture shows whether the bunker was actually mixed through — fed into the mixing strategy and the shift log.

Cut-and-fill per shift

3D differential between consecutive scans: what the firing line removed, what deliveries added — per sector, per line, per shift. Auditable record of how the bunker actually moved, not how the spreadsheet remembered it.

Wherever a tipping bunker feeds a furnace and the firing crew needs to know what is in the bunker before the grab moves — OWL EYE® waste bunker monitoring belongs. The same sensors measure wood chips in biomass fuel bunkers, coal in coal bunkers and sewage sludge in reception bunkers — sludge and wood-chip volume is converted to tonnes via material-calibrated bulk density.

3D-LiDAR sensors are mounted at the bunker ceiling and scan the full tipping pit continuously. The point cloud is reduced to a sector-by-sector volume map; grab position is read from the crane PLC or derived directly from the LiDAR stream. Cut-and-fill is a live 3D diff against the prior scan per sector — what the firing line removed, what deliveries added.

The questions plant managers, firing crew and crane operators ask before specifying LiDAR for an incineration bunker.

Waste Bunker Monitoring

How does waste bunker monitoring with LiDAR work? +
Waste bunker monitoring with LiDAR uses 3D sensors on the bunker ceiling that scan the entire reception pit continuously. Unlike classic point-level measurement, LiDAR bunker monitoring delivers full-surface level measurement across the whole bunker: volume per sector, zone age (FIFO), live grab position and extraction per shift — in waste-to-energy plants, RDF power plants, biomass plants and coal-fired stations. Important context: LiDAR bunker monitoring does not replace fire-protection thermography — it complements it. The infrared camera spots hotspots; the LiDAR system knows volume, material movement and crane tracking. Together they form the complete picture of the bunker. Details: waste & fuel bunker monitoring.
Does bunker monitoring also work with biomass, coal and sewage sludge? +
Yes — the same LiDAR sensors that measure a WtE waste bunker work in biomass power plants (wood-chip bunkers), coal bunkers and sewage sludge reception bunkers. The sensor captures surface geometry regardless of material; conversion to tonnes uses a material-calibrated bulk density — including moisture bands for wood chips and dry-solids calibration for sludge. In biomass and sludge plants, fuel stock is measured in boiler-hours: the system delivers remaining runtime per bunker, crane tracking and cut-and-fill per shift — the same signals as in waste incineration. Dusty coal bunkers get the compressed-air window purge; ATEX areas get the Zone-22 housing variant. Details: waste & fuel bunker monitoring; for open yards see stockpile monitoring.
What does crane tracking in a waste bunker show? +
Crane tracking answers the three questions every control room asks: Where is the crane right now? How much did it take from where — and where did it put it? And is the bunker properly mixed? The live position of the waste-crane grab comes from the crane PLC or directly from the LiDAR scan; every grab move is linked to the volume diff of the affected sector — taken, dropped, restacked, per cycle. The movement picture answers the mixing question: sectors untouched for too long stand out immediately (FIFO indicator), and the mixing strategy for calorific-value homogenisation becomes verifiable — per shift, audit-proof in the log. Details: waste bunker monitoring & crane tracking.
What is a waste bunker — and why is it monitored? +
The waste bunker is the reception and storage pit of a waste-to-energy plant: a deep concrete pit into which collection trucks tip the waste, and from which a crane grab feeds the boiler. It buffers fluctuating deliveries against the continuous fuel demand of the incineration lines — while the crane operator mixes fresh and old, wet and dry fractions to keep the calorific value stable. Waste bunkers are monitored for two reasons: safety (fire detection by thermography, fill-level limits) and operations — volume per sector, age per zone, crane tracking and mixing quality. LiDAR monitoring delivers the second part: waste bunker monitoring with OWL EYE® — the 3D volume picture that thermography cannot see.
How does LiDAR cope with dust, methane and condensation in a waste bunker? +
Waste bunkers in WtE plants are dusty, humid and contain residual landfill gases — none of which defeat a properly specified 3D-LiDAR. OWL EYE® uses 905 nm pulsed time-of-flight with multi-echo processing: dust particles return weak first echoes, the bunker floor or heap returns the strong last echo, and the firmware selects the surface return automatically. Methane and water vapour are transparent at 905 nm, so combustible gas accumulations do not block the beam. The sensor head is housed in an IP65+ enclosure with an optional compressed-air purge ring around the optical window — typical cadence 30 minutes — plus an internal heater and dew-point control to suppress condensation on cold mornings. Optical filtering rejects ambient hall light and tipping-bay floodlights.
How does crane grab position synchronise with the LiDAR bunker scan? +
Two integration paths are supported, and both feed the same dashboard with per-grab volume estimates. Preferred: read grab position from the crane PLC over OPC UA or Profinet. We ship bridges for Liebherr, Demag and Kone control systems — XY, hoist height and grab open/close state stream into OWL EYE® at PLC cycle rate, and each grab cycle is correlated with the bunker delta of that sector. Fallback: pure LiDAR tracking. If the PLC is locked or the crane is third-party, the sensor identifies the grab as a moving rigid object above the heap surface, tracks its XY trajectory and infers the pick / drop events from velocity profile. Accuracy is lower than the PLC path but sufficient for sector-level FIFO and throughput accounting.
What is cut-and-fill in a waste bunker and how often is it computed? +
Cut-and-fill is a differential 3D analysis between two consecutive scans, broken down per bunker sector. The "cut" side records what was removed — typically the firing-line draw by the crane towards the feed hopper. The "fill" side records what was added — truck tipping bay or, in larger plants, a rail delivery. Default cadence is every 60 seconds in continuous mode, with a forced snapshot at shift change and at the start and end of each delivery vehicle event. Output per sector: tonnage drawn to the firing line, tonnage delivered, residual zones, and FIFO age in hours. The firing crew uses this to plan the mixture — fresh high-moisture intake gets blended with older, drier inventory to stabilise calorific value.
Is waste bunker LiDAR safe in dusty / ATEX zones? +
WtE waste bunkers are typically classified as ATEX zone 22 (combustible dust, rare and short-duration occurrence). OWL EYE® ships a zone-22-rated housing for these installations: enclosed optical window, no exposed sparking surfaces, surface temperature below the dust ignition class, and intrinsically-safe wiring on the power and signal sides. A heartbeat self-test runs continuously: the sensor reports its own optical health, internal temperature, window contamination level and last successful scan to the plant DCS, so a degraded sensor is flagged before it causes a measurement gap. Integration with the existing fire-protection system — CO sensors, IR heat detection in the bunker — is supported via a shared OPC UA tag set.
