EU GMP Annex 1 sections 6.7-6.17 define WFI, purified water and clean steam design controls for sterile manufacture since August 2024.

Cut distillation utility demand by 20-60% using reflux optimisation, heat integration and validated simulation-led operating targets.

Steam header reconciliation tracks turbine extractions, PRV bypasses and condensate returns to expose fuel loss and missed power generation.

ORC pinch points of 20 K and 5 K set heat recovery, source cooling and net power output - balance approach temperature with exchanger area.

Four-site study shows pinch analysis can cut pharmaceutical HVAC energy use by up to 70%, pairing heat recovery with GMP compliance requirements.

Cut clean-steam demand by up to 34% with TMP mill pinch analysis, matching refiner steam and paper-machine heat recovery to process needs.
