Batch Traceability
Incoming material passes over a vibrating deck screen and magnetic separator. Oversized bark, stones, and metal are removed. Clean woody fraction advances to the hammer mill circuit. Rejects are composted on-site.
Equipment
Rotary trommel, rare-earth drum magnet, eddy current separator
Stage Parameters
50 mm top / 8 mm bottom
Screen Aperture
100% Fe, non-Fe
Metal Removal
<3% by mass
Reject Rate
550 t/hr screen capacity
Throughput
Cleaned chips enter the hammer mill at 1,450 RPM. Hardened steel hammers reduce material to a particle size of 3–4 mm — the optimal fiber length for die compression. The mill room runs at 92 dB. Cyclone dust collection captures all airborne fines.
Equipment
4× Andritz 315 kW hammer mills, cyclone dust collection, screw conveyor
Stage Parameters
1,450 RPM
Rotor Speed
3–4 mm
Particle Size Out
315 kW per unit
Power Draw
4 parallel mills
Units Running
Milled fiber enters a triple-pass rotary drum dryer operating at 350–450°C inlet temperature. Exhaust heat from the pellet mill powers the dryer, reducing gas consumption by 38%. Output moisture is controlled to ±0.5% of target.
Equipment
Triple-pass rotary drum, baghouse filter, heat exchanger, moisture sensor array
Stage Parameters
350–450°C
Inlet Temp
8% ±0.5%
Moisture Target
24 m triple-pass
Dryer Length
38% from press exhaust
Heat Recovery
Conditioned fiber enters the ring-die press at 80–90°C. Rollers force material through 6 mm die holes at 15,000 PSI. Lignin in the wood fibers melts and re-bonds on exit — no binding agents required. Pellets emerge at 95°C, dense and uniform.
Equipment
6× CPM 9800 ring-die presses, automated die change system, inline NIR analyser
Stage Parameters
15,000 PSI
Die Pressure
6 mm ±0.3 mm
Die Diameter
90–95°C
Exit Temp
650–700 kg/m³
Bulk Density
Hot pellets pass through a counter-flow cooler for 12–15 minutes. Air drawn upward through the pellet bed removes residual moisture and locks the compressed structure. Pellets exit at ≤5°C above ambient — ready for durability testing.
Equipment
Bühler counter-flow cooler, vibrating sieve, pneumatic fines return

Environmental Accountability
The Cause Behind the Product.
Waste into energy. Residuals that would decompose — releasing carbon — are instead compressed into fuel that displaces fossil sources.
Lifecycle Emissions Comparison
92% fewer emissions than coal.
Source: IPCC AR6, RED II Annex V. Lifecycle analysis includes transport and processing.
Carbon Neutrality under RED II Directive
Our pellets meet the 80% GHG savings threshold required for EU renewable energy qualification. Full LCA report available on request.
