Why it matters
Without AI, mis-timed extractions, unbalanced water use, and excess energy draw lead to higher costs and risk of quality defects; equipment wear and uncertain readings can trigger outages during peak campaigns.
From design to safety
Design
AI informs equipment and process design
Early design uses AI to predict energy and water needs from decanter and separator capacities, pump sizing, wastewater handling, and regulatory compliance; it models heat recovery potential and cross-process integration to minimize energy loops and water footprints while ensuring scalable capacity for peak campaigns.

Worked example
Catching a heat exchanger fouling event before energy waste
Illustrative scenario with sample data.
During a campaign peak, the AI detects a gradual rise in energy per tonne and falling heat recovery in the decanter-loop.
Signal in
temperature_in=78C, temp_out=62C, flow=420 L/min, energy_kWh=5.6 per tonne, pH=7.1, water_tonnes=12
System out
Alert sent to mill master and maintenance planner; maintenance task created: clean heat exchanger, recheck flow, restart with verification readings.
Human sign-off: Mill master reviews the alert, approves cleaning window, and assigns maintenance crew.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data collection from meters, sensors, and existing controls; calibrate AI thresholds against current energy and water usage.
Phase 2
Weeks 5 to 8
Prototype AI control live adjustments in non-peak runs; validate decision accuracy and record-keeping.
Phase 3
Weeks 9 to 12
Full integration with control system; operators follow AI recommendations for routine operations and maintenance planning.
Where people stay in charge
- Decisions affecting product safety or compliance must be approved by a certified technician or regulator.
- Critical safety controls require manual override by trained personnel during emergencies.
- All changes to energy and water targets must be documented and signed off by the mill master and QA lead.
Questions owners and crews ask
What metrics does AI track in mill energy and water use reduction?
AI tracks water per tonne, kWh per tonne, and heat recovery, using flow meters, energy meters, and temperature sensors to guide decisions.
Who signs off on energy reduction actions?
