Virgin-furnish supercalendered uncoated rotogravure paper

1. Scope and Applicability

This PCR covers virgin-furnish SC rotogravure magazine/catalogue paper in reels: purchased virgin wood thermomechanical pulp (TMP, without chemical impregnation), purchased bleached softwood kraft reinforcement pulp, and kaolin as in-sheet filler. Mechanical/TMP fibres shall constitute at least 10% of oven-dry fibre furnish, excluding filler and additives from that denominator. No fixed pulp ratio, filler content, grammage, yield or emissions quantity is supplied. The SC commercial grade is evidenced by UPM Cat G; its product sheet establishes chemical/mechanical pulp, fillers and reel delivery, not a particular TMP subtype, supplier, non-integrated mill, recipe or sizing absence. Those narrower conditions are this PCR’s declared applicability requirements, to be verified for each foreground dataset. JRC BREF glossary (printed 850) distinguishes uncoated mechanical magazine paper, including heavily filled SC paper, from woodfree paper.

Uncoated means absence of a surface pigment coating here. Surface sizing is a separate operation: BREF §7.1.5 (printed 666) distinguishes starch/synthetic size application from the pigment slurry described in §7.1.6. This selected route has no surface size press; an uncoated sales label alone does not prove that absence. Wet-end cationic starch or retention aid may still be used and must be collected by actual recipe. Exclude newsprint, recycled/deinked SC, woodfree office paper, pigment-coated LWC/MWC, paperboard, CTMP-integrated production, printed publications and surface-sized variants. A route outside these limits requires separate applicability assessment, not silent reuse of this method.

Field	Value
Reference amount	1
Reference product flow	Uncoated graphic paper and paperboard, mechanical a708be32-4fc9-49c7-a7da-57ce387f98c0
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	finished_paper	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Use calibrated net paper weighing after final slitter/winder; exclude core, wrapper, rejects, internal broke and rework. Retain actual moisture, not assumed air-dry or oven-dry output.
common_basis	all inventory rows	Declared row property	row unit / kg paper	Use per 1 kg reference flow in both languages; protocols aggregate over the same actual net accepted paper P in kg and period. P must be positive.
dry_furnish	tmp_pulp; kraft_pulp; kaolin; primary_sludge; bio_sludge	Mass	kg	Keep delivered wet mass, measured dry-solids fraction, oven-dry fibre, ash and residual water separately; no fixed 90% pulp dryness or sheet moisture. Fibre share excludes minerals, chemicals and packaging.
energy_volume	gas; electricity	Volume / Net calorific value	m3 / MJ	Gas m3 requires measured T/P/Z/composition/dry-wet and matching supplier reference; electricity uses the verified Net calorific value energy chain, 1 kWh = 3.6 MJ. Do not apply gas secondary Mass coefficient as density.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased virgin TMP and bleached softwood kraft, kaolin, actual chemical products and packaging arrive at mill; direct river intake, grid electricity and pipeline boiler gas cross the site boundary.
starting_condition_role	Gate-to-gate papermaking foreground; supplier cradle-to-delivered-gate datasets provide upstream burdens.
product_classification_scope	SC virgin-furnish subset of CPC 32125 only; not all writing/printing paper.
recursive_input_rule	Internal broke, save-all stock, fines, fillers, filtrate and condensate are internal recirculation. Purchased same-category paper is not eligible for this virgin-pulp route without new applicability assessment.
upstream_dataset_requirement	Require subtype/route/moisture-compatible pulp datasets including forestry, pulping, bleaching and supplier transport; grade/quantity-compatible chemicals, packaging and delivered electricity/gas; actual offsite residue transport and treatment. Missing delivered-gate transport is added explicitly once in the resulting model.
disclosure	Site/year, product campaigns, excluded integrated pulping, no sizing/coating proof, boiler and water-treatment boundaries, material and energy contracts, transport coverage, cutoffs and unresolved quantity/background compatibility.

rule_id	Applies to	Rule	source_ids
boundary_manufacturing	sc_papermaking	Include slushing, screening, separate pulp refining/blending, kaolin/chemical dosing, approach flow, wet forming/pressing, cylinder drying, supercalendering, dry slitting/rewinding, wrapping and core insertion; include start-up, breaks and cleaning.	jrc-paper-bref-2015
boundary_utilities	site support	Include gas boiler, internal steam distribution/condensate, raw water treatment, save-all, onsite primary/biological effluent treatment, sludge dewatering and dust collection. No CHP, biomass/sludge burning, purchased heat or integrated pulping is assumed by this selected route; actual presence triggers boundary reassessment.	jrc-paper-bref-2015; epa-gas-combustion-2026
boundary_water_loops	water/fibre/mineral ledger	Keep primary white-water I and secondary white-water II/save-all returns inside the foreground. Track water, long fibre, fines and kaolin separately at both ends of every internal link with equal amounts. Route save-all solids actually returned to furnish as internal recovery; only purge to treatment can become exported sludge.	jrc-paper-bref-2015
boundary_complete_rows	all exchanges	The cards are an atomic route inventory, not a licence to omit unlisted site exchanges. Reconcile purchase/SDS/maintenance, treatment and monitoring registers; add each actually present chemical, pollutant, lubricant, refrigerant, packaging waste and other reject as a separate identity-verified row. Document absence, missing data and cutoffs distinctly; never use blank identity or no measurement as zero.	jrc-paper-bref-2015

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
sc_papermaking	Virgin-furnish supercalendered uncoated rotogravure paper	required	Only the qualified non-integrated route described above	Aggregate foreground manufacturing and onsite support	1 kg net accepted finished SC paper

Physical sequence: purchased pulp → stock preparation/blending → forming/pressing → drying → supercalender → slitting/rewinding → wrapping/dispatch. White-water I returns to approach flow; excess II goes to save-all → recovered fibre/fines/kaolin and clarified water return; net purge goes to treatment → final river discharge and primary/biological sludge. Captured cutting dust goes either to documented internal repulping or net external receiver. Internal steam supply and condensate return are separately measured equal-link transfers. These continuous paper stages form one foreground unit, with stage meters retained; intermediate paper is not another saleable output.

ferric chloride (ferric_chloride)

Conditional effluent coagulation: inventory anhydrous FeCl3 equivalent only when the supplier/background reference is the same. Retain solution mass, measured active fraction and carrier water once; a solution dataset instead uses solution mass, never both representations. The CAS7705-08-0 and name/comment identify inorganic FeCl3; CPC34160 organic-compound classification is a disclosed source error requiring clarification, not an alternative chemical identity.

Alternating current (electricity)

Customer-side grid-average AC at 1–35 kV only. Include stock preparation, pumps, vacuum, dryer auxiliaries, supercalender, winding, dust capture, boiler auxiliaries and water treatment once. Confirm actual voltage, geography/year, losses and supplier mix; reject a plant-production mix for a consumer boundary. The source identifies CN; actual regional mix, reference year, medium-voltage interface and losses remain required and cannot be inferred from the UUID.

natural gas in the gaseous state (gas)

Pipeline gas to the onsite boiler; reference property is Volume, not Mass. Record meter temperature, absolute pressure, dry/wet state, composition and compressibility; reconcile supplier/background m3 definition. Secondary Mass coefficient is not a density. Internal steam has measured pressure, enthalpy and condensate return, without a purchased-steam exchange.

Uncoated printing, writing and packaging paper (wrapper)

Actual uncoated kraft reel wrapping sheet and end-cover material, measured separately from PE film and paperboard core. Confirm fibre composition, grammage, moisture, source gate and supplier basis. The broad packaging-paper name includes this physical subset, but its CPC32129 graphic-paper classification is a disclosed source discrepancy, not packaging-grade proof. A paper bag is not this sheet; a purchased laminated composite wrapper needs its own verified exchange replacing, not duplicating, constituents.

Polyethylene film (pe_film)

Conditional separate polyethylene moisture barrier, not PET film or a composite wrapper. Confirm polymer grade, thickness, measured mass and supplier; physical name/CAS/comment support PE film despite an inconsistent source classification. Only actual noncellular, non-self-adhesive, unreinforced, unlaminated and unsupported film is represented; composite kraft/PE packaging is excluded from this separate-film identity.

Cardboard tube or Paper core (core)

Paperboard reel core of the actual size and grade. Account for new purchases, returned cores, reuse cycles and rejects without assigning the full new-core burden at every reuse. Exclude core and wrapper mass from reference paper. Keep actual received/returned/exported core masses in the physical ledger. Reuse only affects evidence-based service burdens and replacement consumption; it never scales down a real physical return or discard.

Waste solid (screen_rejects)

Actual net exported wet screening rejects from purchased virgin-pulp preparation, conditionally located by the broad industrial-solid-waste identity. Measure wet mass, dry solids, fibre/filler/foreign-material composition, contamination and receiver/provider compatibility. Internal returned stock is not an external export. A shared UUID does not merge this residue with primary sludge, biological sludge, paper trim or captured dust; preserve every actual stream and receiving route separately.

Elementary flows

Water (water_out)

Only final liquid discharge to the river after onsite treatment, Volume/m3. Record all bypasses and receiver; no untreated-wastewater product exchange or resource-water output substitution. Pollutant rows quantify contained loads, not extra wastewater volume. This is the liquid water component, not an assertion that mixed effluent is pure water. Record outfall temperature, measured whole-effluent density and water mass fraction; water-component mass = measured effluent volume * effluent density * water fraction, and water-component volume = water-component mass / documented water density at discharge temperature. Retain actual whole-effluent volume separately for pollutant loads; do not assume density1000 or treat COD/TSS as extra carrier water.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_single_product	qualified SC campaign	One saleable paper output; internal stock/broke/fines/filler recovery are not coproducts and receive no allocation share or avoided-pulp credit. Assign collection/treatment of actual net waste to its source campaign unless a justified subsequent model establishes a different waste/secondary-product boundary.	jrc-paper-bref-2015; eu-pef-allocation-2021
allocation_shared_loads	multi-grade mill utilities/treatment	Prefer campaign/line subdivision and direct meters. For shared remaining burdens use a demonstrated physical relationship: measured steam/enthalpy or electrical duty, and measured hydraulic/organic/solids treatment drivers for wastewater and sludge. Document driver tests, boundary and sensitivity; product-mass shares are not a universal treatment or energy driver. If physical relation fails, justify another relationship using contemporary values; no default allocation factor.	eu-pef-allocation-2021
allocation_two_ledgers	all mass/water/carbon balances	Preserve the unallocated physical graph and component mass/water/carbon balance separately from the partitioned environmental-burden ledger. Allocation changes assigned burdens, not measured coproduct/export masses or either end of an internal link. No simultaneous sludge diversion credit and raw-material recovery credit for the same solids.	jrc-paper-bref-2015; eu-pef-allocation-2021

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
net_basis	all inventory rows	x_i = X_i / P; X_i is attributable net exchange over the same period; P is accepted net finished paper in kg. The finished_paper row is exactly 1 kg.	X_i; P; cp_output	x_i	jrc-paper-bref-2015
dry_components	tmp_pulp; kraft_pulp; kaolin; primary_sludge; bio_sludge	D_i = W_i * s_i; water_i = W_i - D_i; fibre and ash subdivisions require measured composition, not inferred yield. Fibre share = dry TMP fibre / total dry fibre, excluding minerals.	W_i; s_i; cp_furnish; cp_residues	D_i; water_i; fibre share	jrc-paper-bref-2015
effluent_load	cod; bod; tss; nitrogen; phosphorus; aox	L_j = sum(C_j,t * V_t * 0.001); C in mg/L, V in m3, L in kg. Pair concentration and flow at the same final outfall and interval; include bypass; normalize by P. Do not multiply separate annual means.	C_j,t; V_t; cp_effluent; P	L_j / P	jrc-paper-bref-2015
air_load	co2_fossil; co2_bio; co; nox; so2; ch4; ch4_bio; n2o; pm25; pmcoarse; pmover; formaldehyde; benzene	L_j = sum(c_j,t * v_t * dt * 0.000001) for c in mg/m3, v in m3/h, dt in h and identical gas-reference conditions. Reference-O2 correction cannot be applied to concentration alone while retaining incompatible actual gas volume.	c_j,t; v_t; dt; cp_air; cp_dust; P	L_j / P	jrc-paper-bref-2015
particle_partition	pm25; pmcoarse; pmover	E_small = measured PM2.5; E_coarse = measured PM10 - measured PM2.5; E_large = measured TSP - measured PM10 only if sampling/condensable coverage match and all differences are nonnegative. Otherwise retain unresolved size data; no assumed fractions.	cp_dust; matched cumulative loads	mutually exclusive emitted bins	jrc-paper-bref-2015
component_balance	sc_papermaking	For each water, long-fibre, fines, mineral/ash and carbon component: external inputs + generated component = paper + packaging export + net residues + final emissions + inventory change + quantified residual. Internal links cancel only with equal amounts at both ends. Carbon bookkeeping uses kg C from measured stream carbon content or explicitly documented chemical stoichiometry, separately identifying biogenic, fossil and mineral carbon; the wood/kaolin name is not a carbon-content factor. COD/BOD oxygen demand is not physical carbon mass. Include only actual moisture carried by particulate streams, separately from vapour, and reconcile pure-water-component discharge versus mixed-effluent volume without duplicate pollutant/solid mass.	cp_furnish; cp_output; cp_water; cp_residues; cp_air; cp_dust; cp_effluent	unallocated balance and residual	jrc-paper-bref-2015
burden_partition	shared burdens	B_SC = B_direct,SC + sum(B_shared,k * f_SC,k); each f is justified by a measured causal driver and sums to one across served outputs. Keep actual physical exports unchanged.	shared burden; driver records; cp_energy; cp_effluent	assigned burden ledger	eu-pef-allocation-2021

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	all inventory rows	Verify actual physical subset, name/CAS/route/name properties, supplier reference amount and unit chain; UUID resolution alone is not dataset compatibility. Blank UUID remains a named atomic gap.	Supplier specifications; direct flow metadata; basis reconciliation
dq_period	all inventory rows	Use a complete same-period net production denominator; include changes, offgrade campaigns, shutdowns, monitoring gaps and uncertainty. Do not use installed capacity.	Production/meter logs and calibration
dq_completeness	all exchanges	BREF and AP-42 define evidence scope, not recipes or default loads. Actual chemicals, gases and residues outside listed cards require named additional rows; unknown is not absent.	Purchase/SDS/maintenance and environmental registers
dq_indicators	water emissions	COD/BOD and TN/TP/AOX are analytical indicators, not independent molecular species. Preserve analytical/species data and choose nonduplicating LCIA treatment; do not hide high-impact species in sum indicators.	Laboratory method, speciation and LCIA reconciliation

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_scope	finished_paper	Fail applicability when virgin TMP/bleached softwood kraft/kaolin SC route, at least 10% dry mechanical fibre, no pigment coating or no surface-sizing evidence is missing or contradicted; a CPC label or broad UUID does not replace those facts.	jrc-paper-bref-2015; upm-cat-g-2026
validate_measurement	all inventory rows	Require one final 1 kg output, same denominator and temporal aggregation, supported reference property/unit chain, measured moisture/active fraction and supplier/background quantity compatibility. Unsupported conversions or unknown gas volume conventions remain incomplete.	jrc-paper-bref-2015
validate_loops_residues	water/fibre/mineral/carbon ledger	Reconcile equal internal links and separate paper, recovered-stock, primary sludge, biological sludge, wet rejects, captured dust and residual effluent destinations. Any unexplained residual needs investigation, not arbitrary proportional balancing or duplicate allocation. Require actual receivers and offsite treatment.	jrc-paper-bref-2015; eu-pef-allocation-2021
validate_emissions	all elementary outputs	Require correct compartment/species/carbon origin, matched monitoring conditions, nonoverlapping particle bins and separate capture. Retain biogenic CO2 in LCI. NOx excludes N2O and needs explicit NO2-equivalent/species compatibility; COD/BOD/TN/TP/AOX overlap requires explicit LCIA exclusion/mapping. No measurements or quantified justified estimates means incomplete, not passed.	jrc-paper-bref-2015; epa-gas-combustion-2026
