Estimate transport operational benefits, reduced landfill fees, and biogas output from dewatering brewery spent grain.
Raw spent grain contains ~80% water. Dewatering to 30% solids reduces mass by over 40%, cutting transport and disposal requirements while unlocking biogas potential.

Spent grain at 80% moisture contains 800 kg water per tonne. Dewatering to 30% solids removes ~333 kg of water per tonne of raw grain.
With ~40% mass reduction, fewer truck loads are required. At /km over 50 km, benefits compound quickly for high-volume breweries.
Dewatered grain still contains volatile solids. Anaerobic digestion can yield 300-400 m³ biogas per tonne VS, displacing purchased natural gas.
Multi-disc screw presses achieve 20-35% cake solids with low energy (0.5-2 kWh/tonne). Containerised units allow pilot testing before commitment.
