7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
al_subdivide_routes	Species, cocoon condition, and reeling technology	Subdivide and calculate route-specific processes before any allocation or aggregation. Do not allocate burdens through an unconditional average of mulberry/non-mulberry, fresh/dried, or hand/machine routes.	iso-14044-2006; fao-silk-reeling-testing-1999
al_classify_outputs	Pupae, recoverable cocoon/silk material, and residues	Determine product or waste status from the actual function and destination. FAO identifies pupae and several silk residues as potentially valuable outputs; saleable material shall not be silently treated as burden-free waste.	fao-silk-reeling-testing-1999
al_avoid_where_possible	Multi-output processes	First avoid allocation by separately measuring attributable operations or subdividing treatment. Use system expansion only when the downstream study method permits it and the substituted product and evidence are explicit.	iso-14044-2006
al_physical_then_economic	Unavoidable shared burdens	Where subdivision is not feasible, use a documented physical causal relation when defensible. If no defensible physical relation exists, use economic allocation based on contemporaneous net-gate values and quantities for all co-products, and report a sensitivity case.	iso-14044-2006
al_internal_recycling	Internally returned silk, cocoon, water, or heat	Treat internal recycling as an internal loop. Count only make-up inputs and final outputs crossing the reporting-unit boundary; disclose recirculation rates without crediting the same material twice.	iso-14044-2006; eu-txt-bref-2023
al_residual_treatment	Wastewater and final wastes	Assign on-site treatment burdens to the generating route by measured residual quantity and, where treatment demand differs materially, by pollutant load or another documented causal driver.	iso-14044-2006; eu-txt-bref-2023
