Other cereal grain products (including corn flakes)

1. Scope and Applicability

This PCR governs foreground data packages for factory production of other worked cereal grains and cereal products covered by CPC 3.0 subclass 23140. It covers cereal grains that are hulled, rolled, flaked, pearled, sliced, kibbled, pre-cooked, roasted, puffed, or otherwise prepared; cereal germ in whole, rolled, flaked, or ground form; bulgur wheat; and prepared cereal foods such as corn flakes and mixtures of unroasted flakes with roasted flakes or swollen cereals.

The PCR is route-flexible. A dataset shall identify the actual grain species, product form, formulation, and manufacturing route and shall include only the conditional operations that occur. It does not cover semi- or wholly milled rice, husked rice, cereal-based prepared meals and dishes, cereal flour as the sole product, or mixes and doughs for bakers' wares. Agricultural grain production is upstream of the declared foreground starting condition unless the study explicitly extends the boundary.

The default foreground boundary begins with cereal grain or cereal intermediate received at the manufacturing site and ends with finished product at the factory gate. The reference amount is net product mass; packaging is inventoried separately and is not included in the 1 kg product mass.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_subdivide_first	multi_output_processes	Avoid allocation where possible by separately metering or subdividing cereal preparation, utilities, transformation, finishing, and treatment processes, or by system expansion when the study goal permits it.	eu-commission-2021-2279-environmental-footprint
allocation_physical_relation	inseparable_coproducts	If subdivision or system expansion is not feasible, allocate shared inputs and emissions using a documented causal physical relationship. Mass allocation is acceptable only when mass is relevant to the shared process burden; moisture bases shall be consistent.	eu-commission-2021-2279-environmental-footprint
allocation_other_relation	no_relevant_physical_relation	If no relevant physical relationship can be justified, use another documented relationship such as economic allocation, state prices, geography, period, and calculation, and test sensitivity for material co-products.	eu-commission-2021-2279-environmental-footprint
allocation_residue_classification	fractions_residues_and_waste	Classify bran, germ, hulls, fines, off-spec product, and treatment residues according to actual destination and economic status. Rework is an internal loop; a saleable or beneficially used fraction is a co-product; a discarded stream is waste. Do not apply both co-product allocation and avoided-burden credit to the same output.	eu-commission-2021-2279-environmental-footprint; eu-commission-2019-2031-fdm-bat
allocation_shared_utilities	shared_energy_water_and_treatment	Allocate shared metered utilities and treatment burdens with process-specific meters where available; otherwise use a causal driver such as operating time, energy demand, treated flow, pollutant load, or product mass, and disclose the driver and coverage.	eu-commission-2019-2031-fdm-bat; eu-commission-2021-2279-environmental-footprint
