Virgin-fibre creped tissue parent reels

1. Scope and Applicability

This PCR covers non-integrated manufacture of single-ply creped tissue parent reels from purchased virgin bleached hardwood/softwood kraft market pulp: repulping, stock cleaning/refining, wet forming, conventional pressing/vacuum dewatering, steam-heated Yankee plus hot-air hood drying, blade creping, reeling and any parent-reel rewinding/edge cutting and transport protection before mill-gate acceptance. Tissue is a substrate for later conversion, not a counted consumer roll, facial tissue or napkin. [jrc-pp-bref-2015, sofidel-parent-reels]

CPC3.0 32131 also includes cellulose wadding and fibre webs beyond this method. The scope is narrower; the canonical mapping and its ADR govern the accepted relation. Exclude dry-laid/airlaid/nonwoven webs, TAD and hybrid/uncreped routes, recovered-fibre/deinking routes, on-site pulping/bleaching from wood, coatings/lotions, ply bonding, consumer embossing/perforation/folding/log cutting and retail packaging under 32193. Actual different routes require separately reviewed methodology; no classification label establishes applicability. [jrc-pp-bref-2015]

No fixed reel weight, moisture, fibre ratio or absorption equivalence is prescribed.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	P is weighed accepted net tissue at the actual mill-gate moisture, excluding all cores/spools/wrappers and rejected/internal broke; collect using cp_mass. All inventory rows use this same 1 kg denominator.
dry_wet_basis	mass-based pulp, tissue, chemical/formulation and residue moisture-component ledgers	Mass	kg	Record m and same-lot wet-basis moisture w; dry solids d = m*(1-w). A dry-output intensity converts to delivered-output intensity using measured dry output D/P. Do not equate pulp supplier air-dry tonnes, oven-dry tonnes and delivered tonnes. ISO source is scope-only; obtain an applicable validated sampling/test SOP. Auxiliary component mass/moisture does not replace native gas Volume/m3, steam GCV/MJ or electricity NCV/MJ references.
utility_basis	natural_gas, steam, electricity	Volume / Gross calorific value / Net calorific value	m3 / MJ / MJ	Match gas volume conditions, physical steam/condensate mass and enthalpy, supplied-heat provider reference MJ and grid-voltage interfaces independently. 1 kWh = 3.6 MJ is exact unit conversion, not efficiency. A GCV property does not establish net delivered heat; actual k_bg is required.
chemical_basis	wet_strength, retention_aid, defoamer, yankee_adhesive, yankee_pae, release_oil, wwtp_pac	Mass	kg	Distinguish as-supplied formulated mass, dry solids and active ingredient; separate carrier water and each other actual chemical component without double counting dilution water.
emission_basis	co2_fossil; co2_biogenic; co; nox; n2o; methane; methane_biogenic; so2; voc_ethane; pm_fine; pm_coarse; pm_large; water_vapour; effluent_water; cod; bod; tn; tp; aox; tss	Mass / Volume	kg / m3	Match elementary species/origin/medium and quantity definition. COD/BOD use oxygen equivalent, AOX chlorine equivalent, total N/P elemental mass; these indicators are not additive physical species. NOx-to-NO2 convention remains pending until proven. Use mutually exclusive particulate intervals and retain biogenic CO2.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased finished bleached hardwood/softwood kraft market pulp received at tissue mill; upstream production excluded from foreground and linked once
starting_condition_role	foreground input gate
product_classification_scope	CPC:3.0:32131; narrower
recursive_input_rule	Purchased tissue parent reels for mere rewinding or retail conversion are outside this production PCR; internal broke/fibre returns remain physical loops, not upstream purchases
upstream_dataset_requirement	Compatible supplier pulp, chemicals, water, utilities, packaging and actual inbound transport datasets with geography, year, treatment and quantity definitions; unresolved links prevent complete cradle-to-gate claims
disclosure	Distinguish foreground gate-to-gate from linked cradle-to-gate; disclose drying/creping route, included gas boiler versus external steam, treatment and receiver, exclusions, stocks and residuals

rule_id	applies_to	rule	source_ids
boundary_route	tissue_mill	Include all actual stock preparation, forming/pressing/vacuum, Yankee/hood drying, blade creping, parent-reel winding/edge cutting, accepted-reel conditioning and protection, broke/white-water recovery and attributable utilities/treatment within the declared gate. Keep included combustion emissions.	jrc-pp-bref-2015
boundary_conversion	tissue_mill	Stop at the accepted single-ply parent reel: downstream ply bonding, embossing, perforation, folding, log cutting and consumer packaging belong to separate conversion. An integrated plant must separate meters/records and link this upstream output once.	sofidel-parent-reels
boundary_water	tissue_mill	Internal white water, recovered fibres, broke and condensate returns are conserved links. Off-site untreated wastewater transfer and on-site treated direct discharge are alternative routes for the same water, not simultaneous burdens.	jrc-pp-bref-2015
boundary_heat	tissue_mill	An included gas boiler records fuel and actual emissions; its steam is internal. External steam records the supplier input once and its generation burden upstream. Shared utilities need measured allocation; no duplicate fuel and purchased-steam production.	jrc-pp-bref-2015, epa-ap42-gas-2026

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
tissue_mill	Virgin-fibre creped tissue parent reels	required	Declared virgin-fibre conventional creped-parent-reel route	foreground production	1 kg reference flow

Physical stage map: market pulp receipt -> separate fibre stock preparation/refining -> mixing and wet forming -> press/vacuum -> Yankee/hood -> creping blade -> reeling/optional parent-reel rewind and dry edge cut -> accepted reel. White water/save-all fibre/wet and dry broke return to stock; purge goes to actual treatment or an external treatment receiver. Preserve separate stage mass, water, carbon, stock and meter records despite aggregation into one foreground unit. Internal sending and receiving links must have equal amounts, material state and period; physical product outputs are never scaled by environmental allocation shares. [jrc-pp-bref-2015]

Purchased grid electricity (electricity)

Use the verified 1–35 kV grid-average customer interface only when the supply voltage and background loss boundary match; retain pulping, refining, vacuum, presses, fans, winder and treatment submeter readings. Do not apply this UUID to another voltage or dedicated generation route.

The source geography is CN. Actual regional mix, year and provider/loss boundary must match; another grid needs a separately verified identity.

Pipeline natural gas for hood and included boiler (natural_gas)

Meter hood and on-site boiler separately then add their attributable gas once. Reference property is Volume/m3. Match supplier background m3 temperature, pressure, wet/dry composition and compressibility; secondary database mass coefficients are not density. Unmatched volume convention remains an incomplete link.

External steam supplied to Yankee (steam)

Actual externally supplied industrial-boiler steam heat to the Yankee dryer. This physical record has no pressure constraint, but its Gross calorific value/MJ reference does not prove net delivered heat. Collect actual supply/return mass, absolute/gauge pressure, temperature, quality, enthalpy and interface losses; determine a documented provider conversion k_bg from net interface heat to the provider reference MJ. Unknown conversion leaves the dataset link unresolved. The source benchmark 1.15 MWh/t is not a consumption factor. Internal boiler steam remains an internal physical link; never add this purchased-heat background for the same onsite fuel/generation.

Purchased treated process water (process_water)

Measure external make-up, chemical dilution and boiler make-up crossing the foreground boundary; do not count recirculated white water or returned condensate as fresh supply. Convert volume to the Mass/kg reference only with measured density and temperature. An own abstraction route requires its specific resource flow and treatment model.

Conditional permanent wet-strength resin (wet_strength)

Include only for an actual grade requiring this PAE chemistry, supported by supplier SDS and recipe. Measure as-supplied resin mass and solids/active fraction separately; record residual chlorinated species and AOX applicability. Do not apply an epoxy-resin UUID or assume all toilet grades contain wet-strength resin.

Conditional nonionic polyacrylamide retention aid (retention_aid)

Only when actual SDS confirms the nonionic polymer identity; record powder/polymer content versus carrier water, addition point and tank/invoice reconciliation. Cationic or anionic grades require their own matching identities; no fixed dosage is supplied.

Conditional silicone defoamer (defoamer)

Only the actual primary-production PDMS polysiloxane polymer component, confirmed by supplier chemical specification, CAS, grade and viscosity, is represented. The broad silicone record explicitly includes polymerized siloxane fluids; no conflicting polymer identity is stated, but it supplies neither a PDMS-specific CAS nor a ready-to-use defoamer recipe. Match actual polymer mass and provider basis; retain separately measured carrier water and other formulation components without double counting a purchased complete formulation. Other silicone chemistry, recycled route or a whole mixed defoamer requires its own applicable identity/provider.

Conditional PVOH Yankee adhesive (yankee_adhesive)

Use this polymer row only for actual independently purchased PVOH added onsite, confirmed by supply/recipe records; measure supplied dry/wet reference quantity and retain solution water/additives analytically. Record actual onsite preparation water/utilities once. A bought PVOH Yankee adhesive premix instead requires one specific complete-formulation card and compatible provider covering supplier preparation/delivery before use; its polymer/water/additives are composition records, not separate purchases. Patent chemistry is a possible route, not a required blend, grade, concentration or dosage; do not substitute PVAc.

Conditional PAE Yankee coating (yankee_pae)

Measure this coating resin separately from wet-end wet-strength use; reconcile spray-boom delivery, stock change, carrier water and active solids. Apply only if actual supplier resin chemistry matches; an epoxy resin is not a substitute.

Conditional mineral-oil release component (release_oil)

Use this row only for the confirmed petroleum mineral oil actually purchased separately and added onsite to the release recipe; SDS must distinguish mineral oil from vegetable oil, wax and oil-free modifiers, and record actual grade. Separately bought emulsifier/carrier and onsite mixing/utilities are real additional exchanges. If a ready release formulation is purchased, require one specific complete-formulation input and compatible provider covering its preparation/delivery; included oil/emulsifier/carrier are analytical only. Source oil identity alone proves neither premix manufacture nor that the mill uses this chemistry.

Conditional parent-reel PE transport wrap (pe_wrap)

Weigh actual PE film issued to accepted parent reels, including attributable scrap. Exclude wrapper mass from tissue reference mass. Physical film identity is retained despite the source CPC29220 classification defect; supplier film composition and background route must be verified.

Verify actual film construction, polymer grade and additives; this row does not identify a laminated composite wrapper. If a composite is purchased as one physical exchange, identify its complete composition and provider instead of duplicating it with component inputs.

Conditional paperboard parent-reel core (reel_core)

Record only actual paperboard cores, core reuse cycles, new cores and retired cores; weigh tare individually and exclude it from tissue output. Do not apply this paper-core identity to steel reel spools. Returned durable spools retain a separate reusable-service ledger.

Keep actual new, received, returned and discarded core/spool masses in the unallocated physical ledger. Reuse changes documented service burdens and replacement consumption only; it cannot reduce an actual returned or retired object mass.

Conditional effluent-treatment PAC (wwtp_pac)

If on-site coagulation uses this actual PAC formulation, reconcile as-supplied mass, active solids, aluminium basis and carrier water; use the provider convention. This is not a default treatment recipe.

The adopted source explicitly describes a water-soluble solid; this row requires the actual solid PAC reagent and measured assay/hydration. A purchased liquid formulation must have its own matching complete-formulation identity and reference basis, replacing rather than duplicating this solid input.

Accepted creped tissue parent reel (parent_reel)

1 kg net tissue at measured factory-gate moisture, excluding core, spool and wrap. One final product output covers winding/conditioning/dispatch; stage quantities remain in the physical ledger. Broad stock identity is limited here to virgin-fibre CWP creped parent reels and establishes no absorption, sheet-count or retail-roll equivalence.

Waste flows

External tissue trim and rejected broke (broke_export)

Weigh only tissue trim/rejected broke actually transferred outside the mill; disclose wet/dry state, additives and receiver. Internal wet/dry broke returned to the pulper is a loop, not a waste export or new virgin-pulp purchase. Broad waste-paper identity needs actual uncoated tissue state confirmation.

Collected dry-cutting and creping dust leaving the mill (collected_dust)

Only actual separately captured tissue creping/cutting/winding dust leaving the mill is represented by the broad industrial-collector waste identity. Weigh physical wet/dry mass, fibre/coating/mineral composition, contamination, stock change and recipient route; no capture efficiency, occurrence or mass is assumed. Internal repulping is a physical return; captured waste and escaped particulate bins never overlap.

Dewatered paper-production treatment sludge (wwtp_sludge)

Record actual primary/biological sludge exported, wet mass and dry solids, composition, treatment and receiver. Keep retained fibre separate from product sale and internal save-all return; no universal solids fraction.

One row represents one actual physically combined exported sludge stream. If primary and biological sludge leave separately, create separate atomic rows with their own masses/compositions/recipients even when sharing this broad UUID; do not collapse independently handled streams into a collection label.

Alternative off-site wastewater treatment transfer (wastewater_export)

Actual whole untreated tissue-papermaking wastewater transferred to an external treatment provider. The broad industrial-liquid-waste identity does not prescribe composition, legal hazardous classification or treatment. Measure transferred wet mass directly, or M = V*rho_eff(T) using actual mixed-stream density and temperature; determine solids/water fraction and receiver compatibility, with no density1000 assumption. Keep whole-stream volume for concentration-load calculations. Its water component belongs to the transfer water balance, not a simultaneous direct freshwater emission; downstream treatment releases are counted through the provider once.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_subdivide	tissue_mill	Use product/line/campaign submetering to avoid allocation first. Where inseparable shared utilities/treatment remain, demonstrate a causal physical relation using measured electricity, steam enthalpy or pollutant loads; mass is justified only for compatible grades. If physical attribution cannot be supported, document an independently reviewed alternative and sensitivity rather than inventing a fixed share.	eu-pef-multifunctionality-2021
allocation_physical	all inventory rows	Retain unallocated material/water/carbon balances and actual co-product/waste quantities separately from the allocated environmental-burden ledger. Internal broke recycling creates no co-product credit; external recovered-paper/sludge treatment and substitution require receiver and selected end-of-life method, never an automatic avoided-product credit.	jrc-pp-bref-2015, eu-pef-multifunctionality-2021

Conditional rows require proven actual use or documented absence; missing quantities are pending. Extend the inventory for each actual chemical, carrier, packaging waste, treatment nutrient or emitted species absent here. A missing identity is not a licence to bundle flows or substitute a neighbouring product. No empirical/default ranges are provided; compatible foreground collection supplies values. [jrc-pp-bref-2015]

Also screen actual forming fabrics, press felts, creping blades, hydraulic/lubricant replacements and cleaning agents by item and material. Add each actual replenishment and separately handled spent stream as an atomic exchange with its own identity, stock/service-life evidence, physical discarded mass and receiver. Do not assume a consumable recipe, zero wear or a universal service life; actual replacements and burdens cannot be inferred from installed equipment mass.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
accepted_mass	parent_reel	P = sum(gross accepted reel mass - measured core/spool tare - measured wrap tare); reconcile production, delivery and stock; no rejected or returned internal broke in P.	cp_mass	P	iso-solid-dry-matter-scope-2022
same_reference_normalization	all inventory rows	x = X / P, where X is the actual attributable campaign exchange in its row unit and P is accepted net tissue kg at measured gate moisture; retain raw physical ledger and allocated burden ledger separately.	cp_mass; each linked row protocol	x	jrc-pp-bref-2015
dry_conversion	mass-based pulp, tissue, chemical/formulation and residue moisture-component ledgers	d = m*(1-w); D = sum(d for accepted tissue); dry-output intensity I_d becomes delivered-output intensity I_d*D/P. Measured total dry solids is not automatically pure cellulose mass. Auxiliary component mass/moisture does not replace native gas Volume/m3, steam GCV/MJ or electricity NCV/MJ references.	cp_mass; cp_furnish; cp_chemicals; cp_residues	measured dry/wet basis	iso-solid-dry-matter-scope-2022
electricity_conversion	electricity	MJ = 3.6 * kWh; x = MJ/P.	cp_utilities; cp_mass	MJ/kg	jrc-pp-bref-2015
steam_reconciliation	steam	H_net = sum(m_supplyh_supply - m_returnh_return) at the declared interface; match enthalpy datum, state, storage and actual boundary losses once. Q_bg = k_bg*H_net under the verified provider MJ definition; x = Q_bg/P. Never subtract already included losses twice or set k_bg=1 by assumption. Preserve physical steam/condensate kg separately.	cp_utilities; cp_mass	provider-reference MJ/kg tissue and separate physical heat/mass reconciliation	jrc-pp-bref-2015
water_pollutant_load	cod, bod, tn, tp, tss, aox	L = sum(c_k * V_k * 0.001), with c_k in mg/L and matched discharge V_k in m3; x = L/P. COD/BOD as O2, N as N, P as P, AOX as Cl; keep indicators out of physical mass sums.	cp_effluent; cp_mass	kg indicator/kg	eu-paper-bat-2014
particle_partition	pm_fine, pm_coarse, pm_large	Fine = measured PM2.5; coarse = matched PM10 - PM2.5; large = matched total - PM10 only with identical sampling definitions; x = fraction/P. Do not add total or PM10 to the three fractions; unknown partition remains pending.	cp_dust; cp_mass	kg fraction/kg	jrc-pp-bref-2015
complete_period_normalization	all inventory rows	Every existing campaign, batch or lot amount rule and linked collection protocol uses one documented complete reporting-period pool for the same declared product, grade, route, configuration, site and reference state. Accepted-lot wording identifies the denominator only; retain all attributable startup, shutdown, wholly failed or zero-output batches, rejects, work in progress and rework in the raw native-unit numerator records. Count reworked reference product once only when finally accepted. Sum each attributable exchange over this matched pool, divide once by its strictly positive accepted reference-product quantity in the declared denominator unit, and scale to the declared reference quantity. Do not average batch ratios, drop a failed batch, pool unrelated products/periods or replace native numerator units. If the entire matched pool has no accepted output, retain the unnormalized absolute inventory and require review; issue no normalized result or fabricated output. Preserve stock/return and physical-transfer ledgers independently of burden allocation; allocation never removes already-incurred failed/rework activity.	all linked raw collection protocols; accepted reference-product pool; stock and rework links	native exchange unit per declared reference quantity; zero-output pool remains unnormalized

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
identity	all inventory rows	Inspect complete name, CAS, classification, route, comment, reference property/unit and exact species/medium. Verify supplier quantity compatibility separately from identity; disclose metadata conflicts.	supplier/SDS; verified identities
balances	tissue_mill	Close wet mass, dry solids, water and carbon physically with stocks and uncertainty; retain internal-link equality and dust capture/export/air partition. Environmental attribution cannot repair a physical imbalance.	stage ledger and laboratory
route_scope	tissue_mill	No inherited wood-processing data or historic single-mill recipe becomes a tissue default. This route requires verified actual drying, creping, furnish, chemistry and gate moisture.	BREF and actual collection
coverage	tissue_mill	Full campaign includes start-ups, downtime, breaks, cleaning, rejected reels, relevant waste/air/water pathways and background transport links; reveal unsupported methods and unresolved values without setting them to zero.	complete campaign records

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	parent_reel	Require exactly one accepted final product output linked by parent_reel and reference UUID, at 1 kg net tissue; EN/ZH amount, denominator, aggregation and formulas agree. Do not introduce a second reference output for winding-to-wrapping transfer.	jrc-pp-bref-2015
validate_applicability	tissue_mill	Confirm virgin purchased bleached kraft pulp, CWP press/Yankee/hood/blade-creping route and single-ply parent-reel state; reject retail converted products, airlaid/nonwoven, TAD/hybrid and recovered-fibre/integrated-pulping claims under this PCR.	jrc-pp-bref-2015, sofidel-parent-reels
validate_inventory	all inventory rows	Require each exchange to be atomic with matching actual substance, medium/submedium, origin, property/unit and supplier quantity convention. Missing identity, steam pressure/enthalpy, gas m3 definition or NOx basis remains unresolved; do not advertise a complete dataset.	jrc-pp-bref-2015
validate_conservation	tissue_mill	Reconcile physical mass/water/carbon and equal internal links before environmental allocation. Capture/return/export/emission dust quantities do not overlap; three airborne size fractions do not include nested totals. Preserve actual biogenic CO2 and distinct fossil/biogenic methane.	jrc-pp-bref-2015, eu-pef-multifunctionality-2021
validate_discharge	tissue_mill	Require actual receiving medium and treatment boundary; direct freshwater discharge and off-site wastewater transfer cannot duplicate the same load. Known toxic organochlorine/metals and other actual emissions require individual species rows and reconciliation with COD/BOD/TN/TP/AOX indicators. Missing measurements are not non-detects or zero emissions.	eu-paper-bat-2014
