Beans, frozen

1. Scope and Applicability

This PCR applies to single-component frozen bean products manufactured from clean, sound, succulent bean pods or immature bean seeds. It covers green beans, wax beans, lima beans, and comparable beans that are received fresh, prepared, blanched where required for product stability, rapidly frozen, packaged or placed in a declared bulk container, and held frozen to the processing-facility gate.

The foreground boundary begins with fresh beans received at the processing facility. Upstream cultivation and delivery of fresh beans are represented by linked supplier datasets. The foreground includes receiving, trimming or shelling when applicable, washing, sorting, cutting when applicable, blanching, cooling, draining or dewatering, quick freezing, packaging, and frozen storage through dispatch from the facility gate.

This PCR excludes dried beans, canned or otherwise shelf-stable beans, peas, mixed vegetables, seasoned prepared dishes, bean purées, and products for which beans are not the reference product. Distribution after the declared facility gate, retail storage, cooking, consumption, and end-of-life are outside the default boundary.

Elementary flows

Record direct refrigerant emissions from frozen storage under refrigerant_to_air_output using the same system-level refrigerant protocol, allocating once across freezing and storage without double counting.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
al_avoid_allocation	shared preparation, freezing, storage, and utilities	Prefer subdivision, direct metering, batch records, or physically meaningful process separation so that burdens are assigned without allocation.	iso-14044-2006
al_internal_recycling	rework, recirculated water, recovered refrigerant, and internally reused intermediates	Treat internal loops as internal exchanges; record make-up inputs, purge or loss outputs, and the energy needed for recovery, and do not credit the same recovered material twice.	mass-balance-identity
al_joint_products	marketable co-products produced with frozen beans	If allocation cannot be avoided, use a documented physical relationship that reflects causality. If no defensible physical relationship exists, use economic allocation based on a representative twelve-month price period and disclose price sources, volatility, and a physical-allocation sensitivity result.	iso-14044-2006
al_waste_treatment	residues and nonconforming product sent to treatment or recovery	Record the waste flow at the facility gate and apply the chosen treatment or recovery convention consistently; disclose any avoided-product credit and prevent overlap with treatment-provider datasets.	iso-14044-2006
