7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide_first	shared manufacturing and support processes	Avoid allocation by submetering or subdividing storage, preparation, cooking, packaging, sanitation, and wastewater operations wherever practicable.	eu-pef-2021-2279
allocation_physical_driver	residual shared utilities	When subdivision is not practicable, allocate a shared utility by a documented causal physical driver such as metered equipment time and load, occupied storage volume-time, treated wastewater volume and load, or packaging-machine throughput; use mass only when it represents the physical relationship.	eu-pef-2021-2279; schmidt-rivera-azapagic-2019-ready-meals
allocation_seafood_outputs	seafood residues and recovered materials	Classify each outgoing material as co-product or waste from its actual legal and economic status. For a co-product, prefer subdivision or system expansion, then a documented physical relationship; use economic allocation only when no defensible physical relationship exists. Do not credit a waste destination as avoided production inside the factory-gate result unless an explicit system-expansion scenario is reported separately.	eu-pef-2021-2279
allocation_recipe_batches	multi-product batches	Allocate shared batch inputs to saleable meal variants using measured recipe mass, actual yields, equipment occupancy, and rework transfers; disclose the rule and prohibit allocation to rejected product as if it were saleable output.	eu-pef-2021-2279
