# Wool, degreased or carbonized, not carded or combed

## 1. Scope and Applicability

This PCR covers saleable loose sheep-wool fibre that has been degreased by aqueous raw-wool scouring or has subsequently been carbonized to remove vegetable matter, and that has not been carded or combed. It supports gate-to-gate foreground data production for a declared `degreased_route` or `carbonized_route`. An integrated carbonized route includes both route modules; a carbonizing-only facility supplies an upstream dataset for its purchased scoured-wool input.

The route, sheep-wool fineness class, incoming contamination state, carbonizing chemistry, recovery configuration, and moisture basis shall be declared and modelled separately. Do not average degreased and carbonized production, coarse and fine wool, pure wool and blends, or alternative carbonizing chemistries unless the dataset represents a disclosed production-weighted mix and retains the underlying route records.

The verified Tiangong reference row is `Scoured Wool`, a narrower representative of the degreased route. It is mandatory for reference-flow identity in this candidate PCR, but it is not an exact identity for carbonized loose wool. A carbonized dataset shall retain the UUID and explicitly state the limitation; it shall not claim that Tiangong provides a carbonized-wool-specific product flow.

Excluded are greasy/raw wool sold without scouring, fine or coarse animal hair other than sheep wool, wool/synthetic blends, wool waste and noils, carded or combed wool, tops and slivers, yarn, fabric, fabric carbonizing, dyeing, bleaching, mothproofing, spinning, and downstream textile manufacture. Sheep husbandry and wool production are outside the foreground boundary but require upstream datasets when the study boundary includes them.

All `reasoned_estimate` ranges below are deliberately broad candidate-stage QA screens, not default inventory values or conformance limits. Replace them with reviewed route- and site-specific evidence after three consecutive representative production periods are available, when equipment or chemistry changes materially, or before publication if the range would affect a comparative assertion.

## 2. Product Category Identity

| canonical_pcr_id | pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.yarn-and-thread-woven-and-tufted-textile-fabrics.wool-degreased-or-carbonized-not-carded-or-combed |
| classification_refs | CPC 3.0: 26130, Wool, degreased or carbonized, not carded or combed |
| covered_products | Loose sheep-wool fibre sold after aqueous degreasing/scouring; loose sheep-wool fibre sold after a declared carbonizing route; both not carded or combed |
| excluded_products | Greasy/raw unscoured wool; non-sheep animal hair; wool/synthetic blends; wool noils or waste; carded or combed wool; tops, slivers, yarn and fabric; dyed, bleached or mothproofed products unless those treatments are reported in a separate dataset |
| representative_product | Saleable loose scoured sheep wool on the `degreased_route`; this is narrower than the full category and is the verified Tiangong identity representative |
| production_route | Route-conditioned: `degreased_route` = opening/de-dusting, aqueous scouring, rinsing, mechanical dewatering and drying; `carbonized_route` = scoured-wool input plus declared loose-fibre acid impregnation, hydroextraction, drying/baking, mechanical removal, neutralization/rinsing and final drying |
| market_state | At the preparation-facility gate, loose, saleable, not carded or combed, with measured moisture and declared route, fibre-diameter class, residual grease and vegetable-matter specification |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Preparation of loose sheep-wool fibre suitable for subsequent spinning preparation, after declared degreasing or loose-fibre carbonizing and before carding or combing |
| How much | 1 kg net dry mass of saleable output at the preparation-facility gate |
| How well | Meets the producer's declared moisture, residual grease, vegetable-matter and quality specifications; route and wool-fineness class are stated; no carding or combing is included |
| How long or cycle | One completed production batch or campaign; no use-life duration applies |
| reference_flow_link | One reference flow per dataset. The verified `Scoured Wool` row represents the degreased route; a carbonized-route dataset uses it only with the mandatory narrower-identity limitation disclosure. |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg net dry mass |
| Reference product flow | Scoured Wool `1f286780-8831-47b4-88dd-582d6b7f8947` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | route (`degreased_route` or `carbonized_route`); sheep-wool fibre-diameter class; pure-wool status; incoming material state; output moisture basis and method; residual grease specification; vegetable-matter specification; not-carded-or-combed state; carbonizing chemistry when applicable; carbonized-flow UUID limitation when applicable |

When constructing a foreground data package, the items listed in `Required qualifiers` must be declared in dataset metadata, process notes, reference-flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_dry_mass` | Reference product and all mass-normalized results | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Report the reference amount as net dry mass. Measure gross/net output mass and moisture for the same batch; retain the moisture method and convert using `dry_mass = wet_mass × (1 - moisture_mass_fraction)`. Do not mix as-delivered and dry-mass denominators. |
| `mass_unit_conversion` | All material inputs, products, by-products and wastes | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Preserve source records in their original units and convert to kg with documented factors; tonne-based indicators use 1 t = 1,000 kg. |
| `water_accounting` | Scouring, rinsing, neutralization and cleaning water | Volume or mass, as metered | L or m3, with conversion stated | Separate gross intake, internally recycled water and discharged wastewater. Net freshwater consumption equals gross intake minus water returned from an external system, not internal recirculation; report internal reuse separately. |
| `energy_accounting` | Electricity, steam, direct fuel and recovered heat | Energy | MJ and kWh, with conversion stated | Record purchased electricity, fuels and steam separately. Do not add recovered internal heat as purchased energy; disclose direct versus indirect heating and convert to MJ only after preserving carrier-specific records. |
| `chemical_solution_basis` | Detergent, alkali, mineral acid and neutralizing agents | Mass | kg active substance and kg solution | Record both delivered solution mass and concentration; calculate active-substance mass. Never average sulphuric-acid, gaseous-HCl, aluminium-chloride, sodium-acetate and ammonia routes. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |

| product_classification_scope | Loose sheep wool after degreasing or loose-fibre carbonizing, not carded or combed; excludes non-sheep hair, blends and later textile transformations |
| recursive_input_rule | Purchased scoured wool entering a carbonizing-only facility remains a same-category technosphere input. Link one upstream degreased-wool dataset and stop recursive expansion at that link; do not replace the upstream burden with the carbonizing dataset itself. |
| upstream_dataset_requirement | Supply chain datasets are required for greasy/raw wool production, purchased scoured wool, chemicals, water, energy carriers, transport when included by study scope, and off-site waste or wastewater treatment. The upstream scoured-wool dataset shall be route- and fibre-type compatible. |
| disclosure | State route, facility configuration, geographic and temporal coverage, whether scouring and carbonizing are integrated, incoming and outgoing moisture basis, wool-fineness class, recovery/recycling configuration, wastewater destination, excluded treatment steps, and the narrower Scoured Wool UUID limitation for carbonized output. |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `boundary_route_modules` | foreground_process_selection | Include only the route modules actually operated. A degreased dataset includes aqueous scouring and drying; an integrated carbonized dataset includes scouring and carbonizing; a carbonizing-only dataset begins with an upstream scoured-wool input. | `eu-txt-bref-2023` |

| `boundary_carbonising` | loose_fibre_carbonising | When the carbonized route applies, include acid preparation and impregnation, hydroextraction, drying and baking, crushing/removal of carbonized vegetable particles, neutralization/rinsing, final drying, acidic wastewater and dust/residue management. | `eu-txt-bref-2023` |
| `boundary_excluded_steps` | downstream_and_nonproduct_operations | Exclude sheep husbandry, carding, combing, spinning, dyeing, bleaching, mothproofing, fabric carbonizing, packaging beyond the facility's saleable-output gate, and downstream textile manufacture; represent any included exception as a separately identified process. | `un-cpc-30-2025`; `eu-txt-bref-2023` |

| `allocation_route_separation` | multiple_wool_routes_and_fineness_classes | Use production records to separate degreased and carbonized routes and wool-fineness classes.

| `calc_dry_mass` | All wool inputs and outputs | `dry_mass_kg = net_wet_mass_kg × (1 - moisture_mass_fraction)`; use matched sample and weighing period. | net_wet_mass_kg; moisture_mass_fraction | dry_mass_kg | `iso-14044-2006` |
| `calc_route_yield` | Each route and fibre class | `dry_yield = saleable_output_dry_kg / matched_input_wool_dry_kg`; report rejects and residues separately and do not mix routes or fineness classes. | saleable_output_dry_kg; matched_input_wool_dry_kg | dry_yield | `eu-txt-bref-2023` |
| `calc_normalized_inventory` | Each foreground inventory row | `normalized_amount = matched_period_amount / matched_saleable_output_dry_kg`; keep original unit and conversion factor in evidence. | matched_period_amount; matched_saleable_output_dry_kg; conversion_factor | amount per kg dry reference output | `iso-14044-2006` |
| `calc_water_balance` | Each route | Report gross intake, internal recycle and discharge separately; `water_balance_difference = gross_intake - discharge - water_in_product_or_residue - measured_other_losses`, with evaporation disclosed rather than forced to zero. | gross_intake; recycle_volume; discharge; water_in_product_or_residue; measured_other_losses | route water balance and reconciliation difference | `eu-txt-bat-2022-2508` |
| `calc_grease_recovery_rate` | Aqueous scouring by wool-fineness class | `grease_recovery_rate = recovered_saleable_grease_kg / raw_wool_input_t`. Compare only matching classes: coarse wool typically above 35 µm uses 10-15 kg/t; extra-/super-fine wool typically below 20 µm uses 50-60 kg/t. For 20-35 µm or mixed/unknown classes, collect and report the rate without applying either interval. | recovered_saleable_grease_kg; raw_wool_input_t; fibre_diameter_class | kg recovered grease/t raw wool | `eu-txt-bat-2022-2508` |
| `calc_carbonising_conditions` | Sulphuric-acid loose-fibre carbonizing | Record bath acid concentration, retained acid and water after hydroextraction, drying temperature, baking temperature and final pH. The BREF typical description is 6-9% mineral-acid solution, 5-7.5% sulphuric acid and 50-65% water retained after pressing/centrifugation, drying at 65-90 °C, baking at 105-130 °C and final pH 6; values outside these are flagged for explanation, not automatically overwritten. | bath_acid_percent; retained_acid_percent; retained_water_percent; drying_temperature; baking_temperature; final_pH | disclosed carbonizing-condition record and QA flag | `eu-txt-bref-2023` |
| `calc_wastewater_load` | Each wastewater stream | `load_kg = concentration_mg_per_L × discharge_volume_L / 1,000,000`; sum only matched samples and volumes and state interpolation. | concentration_mg_per_L; discharge_volume_L | kg pollutant by stream and route | `eu-txt-bat-2022-2508` |
| `calc_mass_reconciliation` | Each route | Reconcile dry wool input with saleable dry wool, recovered grease, dry residues, rejects and sampled losses. Investigate and disclose material imbalance; do not use a balancing flow to conceal missing records. | dry_wool_input; saleable_dry_output; recovered_grease; dry_residues; rejects; measured_losses | mass-balance difference and explanation | `iso-14044-2006`; `eu-txt-bref-2023` |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `dq_route_identity` | Dataset identity | Declare one route or a documented production-weighted mix, the process modules included, pure-sheep-wool status, fibre-diameter class and not-carded-or-combed state. | Product specification, process flow diagram, lot records and route-production totals |
| `dq_reference_uuid_limit` | Reference flow | Use the verified Scoured Wool UUID. For carbonized output, state that it is a narrower degreased-route representative and no carbonized-specific UUID was verified. | Reference-flow metadata and manifest review limitation |
| `dq_temporal_representativeness` | Foreground data | Cover a full reporting year where available; otherwise cover at least three consecutive representative production periods and disclose seasonality, shutdowns, abnormal conditions and exclusions. | Production calendar, meter coverage and exception log |
| `dq_mass_and_moisture` | Wool and solid streams | Use calibrated weighing and matched moisture or dry-solids results; do not mix wet and dry masses. Complete route-level mass reconciliation. | Calibration certificates, sampling records, laboratory results and reconciliation workbook |
| `dq_water_energy_chemicals` | Major resource inputs | Reconcile meters and dosing records to invoices or stock movement; preserve carrier and chemical identities and disclose shared-utility allocation. | Meter calibration, invoices, stock reconciliation and allocation workbook |
| `dq_emissions_wastewater` | Direct releases and transfers | Use pollutant-specific records and matched flows; retain sampling location, method, laboratory, detection-limit treatment and wastewater destination. | Monitoring plan, chain of custody, analytical reports, permit records and transfer notes |
| `dq_estimate_replacement` | All `reasoned_estimate` ranges | Use reasoned ranges only to flag records for review. Never populate missing foreground values from them. Replace them after three consecutive representative periods, after material process change, or before publication-critical comparison. | Range replacement log, reviewed site statistics or stronger external evidence |
| `dq_source_applicability` | External evidence | Document whether each BREF/BAT statement is descriptive, typical or normative and whether installation scale and route match; do not turn a typical process description into an emission limit. | Source applicability note and reviewer approval |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `validate_reference_identity` | reference_flow | Fail when the reference product UUID, mass-property UUID, unit-group UUID or kg unit differs from this PCR. For `carbonized_route`, also fail when the narrower-identity limitation is absent. | `un-cpc-30-2025` |
| `validate_route_process_set` | process_map_and_inventory | Fail when the declared route and included modules conflict: degreased requires scouring; integrated carbonized requires scouring plus carbonizing; carbonizing-only requires carbonizing and one upstream scoured-wool dataset. | `eu-txt-bref-2023` |
| `validate_scope_qualifiers` | product_identity | Fail when route, sheep-wool fineness class, pure-wool status, incoming state, output moisture basis, residual grease/vegetable-matter specification or not-carded-or-combed state is missing; reject blends and downstream forms from this PCR. | `un-cpc-30-2025`; `eu-txt-bref-2023` |
| `validate_no_unconditional_average` | aggregation | Fail when degreased and carbonized routes, different carbonizing chemistries, pure wool and blends, or coarse/fine wool are averaged without route-specific records, production weights and an explicit mixed-product scope. | `eu-txt-bref-2023` |
| `validate_grease_recovery_conditioning` | recovered_wool_grease | Apply the 10-15 kg/t raw wool screen only to coarse wool typically above 35 µm and 50-60 kg/t only to extra-/super-fine wool typically below 20 µm. For other or mixed classes, report foreground rate without either screen. Flag outliers for explanation; do not replace observations. | `eu-txt-bat-2022-2508` |
| `validate_carbonising_conditions` | sulphuric_acid_carbonising | Require measured bath/retained-acid conditions, drying and baking temperatures, neutralizing agent and final pH. Flag departures from the BREF typical condition ranges for route evidence and product-quality review; do not automatically fail a documented alternative technology. | `eu-txt-bref-2023` |
| `validate_recovery_and_water_disclosure` | aqueous_scouring | Require gross water, recycle, discharge, recovered grease, dirt/sludge and wastewater destination. Flag absent grease recovery or water recycle for BAT applicability review rather than silently assuming zero. | `eu-txt-bat-2022-2508` |
| `validate_foreground_completeness` | all_foreground_rows | Fail when a collected/calculated row lacks a collection protocol, matched temporal coverage, normalization basis or supporting record. Treat missing values as incomplete; never fill them from a `reasoned_estimate` range. | `eu-txt-bat-2022-2508`; `iso-14044-2006` |
| `validate_mass_balance` | each_route | Fail when wet and dry bases are mixed. Flag material dry-mass imbalance for investigation and require an explanation for unresolved difference; prohibit undisclosed balancing flows. | `iso-14044-2006` |
| `validate_allocation` | multifunctional_operations | Fail when co-product or shared-treatment allocation is undisclosed or when economic allocation is used without first documenting subdivision/system-expansion and physical-relationship assessment. | `eu-pef-2021-2279`; `iso-14044-2006` |
