1. Scope and Applicability

This method covers unprinted, individually hand-formed cotton-rag paper sheets for drawing and watercolour at the manufacturing gate. The furnish is sorted clean cotton garment cuttings, already cut to suitable size, without blends, inks, coatings or elastic. Sheet formation uses a handheld mould and deckle, followed by couching on wool papermaking felts, hydraulic pressing, loft drying, gelatin tub sizing and redrying. Electric beating and press drives are permitted and must be measured. The defined utility configuration uses purchased low-voltage electricity and tap water; gelatin heating and any auxiliary drying heat are electric, and residual wastewater goes to external treatment.

Khadi's Karnataka producer description supports the cotton-cutting, Hollander, hand-mould, felt, hydraulic-press and loft/gelatin sequence. It does not establish its undisclosed internal-size formula. A supplier-documented ketene-dimer emulsion is a separately declared internal-sizing option, not an assertion about that mill's recipe. Sites must document their actual formulation, moisture and performance. No factory recipe, yield, energy consumption, discharge factor or industry-wide range is supplied here.

Exclude continuous Fourdrinier or cylinder/mould-machine webs (even if marketed as traditional), bamboo/lokta/hemp/linen or wood-pulp furnish, bleached-on-site or dyed products, dry chopping/dust-generating preparation, laminating, mineral-coated sheets, converted notebooks and packaging board. Fuel-fired or steam-heated drying and onsite biological wastewater treatment require a separately reviewed inventory extension; do not silently apply this electric/offsite-treatment route to them. Surface gelatin sizing does not imply mineral coating or a printed finished article. Handmade status never establishes zero electricity, zero purchased heat or zero environmental emissions.

Declare these qualifiers in the foreground data package. The broad product UUID encompasses this subset without a contrary route restriction. UUID identity does not supply the site's cotton recipe, moisture basis or background dataset. One kilogram is delivered net mass including actual residual moisture and retained sizing, not one kilogram oven-dry fibre, packaging or unfinished wet sheet. A mass reference alone does not prove equivalent drawing service between products.

The aggregate unit prevents counting the same paper once before and once after sizing/packing. Retain separate stage balances: furnish → vat → pressed wet sheets → first-dried sheets → sized wet sheets → redried accepted sheets. Stage transfers are physical quantities with paired equal sender/receiver mass and moisture, not additional reference product outputs. Record white-water and fibre returns by event and dry solids, as well as inventories at period start/end. Do not count returns as new receipts or as avoided-production credits.

Inputs

Product flows
Cotton cloth cutting furnish (cotton_input)

Use only sorted, pre-cut, clean cotton garment cuttings without synthetic blends, coatings, printing ink, or elastic. This broad rag identity includes that subset; do not model virgin cotton or cotton linters with it. Weigh consumed as-received mass and sample moisture; retain dry cotton mass separately. Verify supplier preparation and upstream burden allocation. Confirm the actual supplied, prepared secondary material is represented by the Product identity and disclose supplier preparation, legal/product-versus-waste status and allocation; an actual incoming waste transfer needs its own applicable waste identity and boundary review. Neither scrap classification nor purchase alone establishes zero upstream burden.

Meter fresh water supplied for soaking, beating, vat makeup, felt washing, equipment cleaning and sizing dilution. Convert measured volume to mass with documented site density and temperature, not the database secondary coefficient. Exclude internal recirculation from fresh input; water in emulsion is already part of that product mass. Use an actual local water-supply background.

Include electric Hollander motor, pumps, hydraulic press power pack, ventilation, electric gelatin-bath heater, auxiliary electric drying/conditioning and attributable storage/cleaning power. Convert kWh to MJ using 3.6; the database property name is retained and does not imply electricity is a fuel. Keep stage submeter totals; sum each kWh once and link location/time/voltage-compatible grid background.

Ketene-dimer internal sizing emulsion (sizing_emulsion_input)

Measure one purchased ketene-dimer sizing emulsion added near the end of beating. Declare brand, current formulation, solids fraction, pH, carrier-water fraction and storage conditions. Supplier instructions establish a possible hand-papermaking option, not Khadi composition or a universal dose. Resolve the neutral-pH instructions versus linked acidic Hercon SDS before claiming pH or background compatibility. The AKD component identity, including its synthesis/emulsification metadata, does not establish the actual supplied mixture, complete composition or supplied-emulsion reference mass; UUID remains blank. No starch, alum, dye or filler is presumed present.

Use the selected physical powder identity only for concentrate/dry/grind gelatin with supplier-confirmed purity above 99.5%, CAS 9000-70-8. Weigh new powder added to the electrically heated aqueous tub; report animal origin, residual moisture, bath stocks, spills, spent solution and retained dry gelatin. Do not equate wet sizing-bath mass to powder consumption or import a database recipe. Actual supplier composition and powder-state compatibility remain required.

Wool papermaking couching felt (felt_input)

Measure the actual finished wool papermaking couching felt used over its documented service interval. The broad finished Felt physical Product identity includes this qualified subset without an opposing material or application route; require actual wool fraction, felted structure, dimensions, grade, reuse/wash history and supplier compatibility. It does not establish a bedding blanket, raw wool, synthetic vacuum-bag breather or matched felt-production background. Retain dry felt, water and in-use/stored inventories with actual purchase/replacement/retirement events. Keep the full physical gate and stock ledger separate from environmental consumption attributed by documented actual service to this reporting period; no assumed lifetime, sheet-count mass factor or duplicate replacement burden.

Uncoated paper wrapping (wrapping_input)

When sheets are wrapped at the gate, weigh one uncoated paper wrapping grade consumed, including documented stock changes and offcuts. The broad uncoated-paper record includes packaging paper without a contrary route restriction; require the actual grade and supplier background. Keep wrapping out of the reference net paper mass. If delivered loose, document absence; never infer other packaging has zero mass. Actual discarded wrapping offcuts and additive containers, if present, need independently weighed and identified waste records; do not merge them with cotton rejects, sludge or spent felt.

Cotton-rag papermaking wastewater to external treatment (wastewater_output)

Measure the actual aqueous process wastewater crossing the gate after internal fibre recovery, including vat bleed, wash water and diluted spent sizing bath only where this is the actual separately characterized transfer accepted by its recipient. Preserve event volumes, calibrated transferred bulk mass or volume × measured event density, sampling locations, pH, temperature, COD/TOC, TSS, BOD and additive-specific analytes; identify sewer/tanker and actual external treatment. The selected broad industrial liquid-Waste Mass/kg identity applies only to this liquid physical stream, with no specified disposal or treatment route. Do not assume 1000 kg/m3, apply the sizing-product SDS density to effluent, or treat bulk wastewater kg as water kg: independently determine water and suspended/dissolved solids/additives for the physical balance. Keep volume-based pollutant-load analysis separate from bulk mass normalized to the reference. The linked SDS does not authorize product disposal to drains; require actual recipient acceptance of composition, pH and loading. Concentrated/unused sizing, spill waste or other separately collected liquids require individual characterized exchanges, not automatic mixing into this row. No manganese-slag, silicon or recovered-fluting-specific wastewater substitute, elemental freshwater discharge or matched treatment background is implied.

Rejected unblended cotton cloth cuttings (cotton_reject_output)

Weigh actual cotton-only sorting rejects removed from the accepted furnish; record moisture, physical reason for rejection, contamination and specific recipient. The broad industrial solid-Waste identity is restricted to this separately collected non-reused cotton-cutting stream. Preserve wet mass, dry cotton/water, stock movements, actual waste/product status, hazard and receiver/provider acceptance; it sets no disposal/recovery route or matched treatment burden. Mixed synthetic, yellow-stained and garment-making-specific records remain incompatible substitutes for this declared stream. Segregate non-cotton contaminants and separately collected dry fine lint as their own actual exchanges; do not merge them with these coarse cuttings or wet sludge.

Weigh unreused dewatered filter/settling cotton-fibre solids transferred offsite; sample dry solids, water and actual sizing/additive contamination and obtain specific receiver acceptance. The broad industrial solid-Waste identity applies only to this separately collected solid or dewatered semisolid stream from physical fibre recovery, not biological-treatment sludge or a liquid effluent. Keep wet/dry mass, composition, hazard, stocks and recipient/treatment compatibility separately traceable; same UUID on other waste rows does not merge streams, prescribe treatment or prove a background. Fibres actually returned to the vat remain internal; water-treatment-chemical-specific sludge is not a substitute.

The broad industrial solid-Waste identity applies only to this separately collected discarded felt, without an assumed disposal/recovery route or treatment burden. Match in-use/stock and retirement records to replacement/service attribution without treating retained water as new wool or sharing a physical waste mass with other rows of the same UUID. Unknown synthetic textile or wool-spinning waste is not substituted; verify actual fibre composition, contamination, waste status, hazard and receiver/provider acceptance.

8. Foreground Data Collection, Calculation, and Quality Rules

Data Collection Protocols

Collect all applicable events for a representative reporting period covering routine batches, failed sheets, rework, cleaning and seasonal drying conditions. Declare exact dates and production coverage; do not substitute a historical mill case for current site data. The denominator is the sum of accepted conditioned net finished kg for exactly that period and route. Keep measured work-in-progress transfers and stock changes in the separate physical and attribution ledgers when reconciling attributable period exchanges; unfinished stock is not accepted finished paper and does not change this output denominator. Keep stage data despite the single aggregate unit.

normalize_periodall inventory rowsFor each non-reference exchange, normalized amount = attributable total physical exchange for the period / accepted net finished paper kg for that period. Preserve the physical totals and their units; only handmade_paper_output is fixed at 1 kg.period exchange totals; cp_output; applicable row protocolexchange amount per 1 kg reference floweu-pp-bref-2015
dry_masscotton_input; handmade_paper_output; cotton_reject_output; sludge_output; spentfelt_outputdry solids kg = wet kg × measured dry-solids fraction; water kg = wet kg minus dry solids kg. Retained additive solids are not cotton; report each separately. This diagnostic never replaces the delivered wet reference.wet mass; tested dry-solids fraction; additive retentionphysical dry-solids and water ledgereu-pp-bref-2015
physical_water_balanceevaporation_outputevaporation kg = incoming molecular H2O kg plus chemically formed H2O kg minus chemically consumed H2O kg minus exported liquid-water component and retained water kg minus change in site molecular-H2O stock kg. The simplified incoming-minus-exported/retained/stock equation applies only where relevant H2O reactions are absent or independently evidenced negligible within declared measurement uncertainty. AKD hydrolysis consumes H2O; for the actual optional AKD branch, require independent reaction-extent evidence, with no assumed hydrolysis fraction, rate or complete conversion of the purchased AKD. Include purchased-material water, accepted-sheet moisture, each waste's actual water and offsite effluent water (bulk liquid kg × measured water fraction, not total liquid mass); internal recirculation cancels once at both ends. Confirm with stage drying/bath measurements; report unresolved residual rather than assigning unmeasured evaporation.cp_water; cp_additives; cp_output; cp_wastewater; cp_wastes; cp_balancemeasured/reconciled evaporation kg and closure residualeu-pp-bref-2015; yan-akd-hydrolysis-2019

physical_carbon_balanceall inventory rowsReconcile measured incoming carbon, outgoing carbon in accepted paper and each waste/effluent, and stock changes; distinguish cotton/gelatin biogenic and sizing/packaging source fractions from supplier or analytical evidence. Do not infer a carbon fraction from flow name. If actual biogenic CO2 occurs, retain a separate LCI exchange with proper media and measured source; a GHG reporting convention cannot delete it. Track independently evidenced AKD reaction products in their actual retained, exported or emitted destinations; any actual CO2 requires separate quantity, species/media and carbon-origin evidence. Hydrolysis alone does not establish an emitted CO2 quantity or origin.measured composition; supplier carbon origin; cp_balancephysical carbon ledger and residualeu-pp-bref-2015

Data Quality Requirements

9. Validation Rules

rule_idApplies toRulesource_ids
validation_referencereference productExactly one accepted finished output links to the reference; require cotton and hand-mould route, moisture, acceptance and all qualifiers. Stage wet/dry papers are internal transfers, not duplicated product outputs.khadi-cotton-route
validation_denominatorall inventory rowsReference, collection, aggregation and all normalized rows use 1 kg accepted net conditioned finished paper. Do not divide by dry fibre, mould area, number of wet sheets, gross wrapped mass or rejected output without explicit consistent conversion.eu-pp-bref-2015
validation_energyelectricity_inputElectric motor/press and heating records must be complete. Loft or hand labels cannot justify zero; physical heat diagnostics cannot duplicate purchased electricity. Other utility configurations require a reviewed atomic-flow extension.eu-pp-bref-2015
validation_waterwater, wastewater, recovery and solidsReconcile stock-aware fresh/retained/discharged/evaporated molecular H2O, independently evidenced chemical H2O formation/consumption and dry-component transformations; whole-mass or elemental closure does not establish H2O-species closure. Accept the simplified evaporation equation only for absent or independently evidenced negligible H2O reactions at declared uncertainty; unknown reaction terms cannot pass as zero, evaporation or a fitted residual. For actual AKD use, check extent/speciation evidence without assuming complete hydrolysis, a rate or a CO2 amount/origin. Use matched concentrations and volumes; distinguish offsite treatment input from direct emissions and preserve the external treatment burden.eu-pp-bref-2015; yan-akd-hydrolysis-2019
validation_additivessize and gelatinConfirm supplied formulation, wet/dry quantity basis, purity, bath stocks and retained sizing. Resolve current pH/formulation before acid-free claims; the linked old SDS and generic AKD component cannot establish this emulsion's background compatibility.chp-sizing-directions-2014; solenis-hercon-sds-2018
validation_completenessdata packageEach exchange is atomic and retains unresolved identity or numerical gaps; no invented UUID, default factory quantity or silent zero. If actual emissions include particles, specify disjoint size bins without summing overlapping totals; preserve actual biogenic CO2 regardless of GHG convention. Added emissions require media/species/unit evidence. Review actual maintenance-fluid exchanges, dry-fibre capture and outdoor releases; absence of dry chopping does not prove their absence, and no paper-machine dust quantity is borrowed.eu-pp-bref-2015

boundary_actual_consumablesinventory completenessVerify actual press model, hydraulic working-fluid and lubrication specifications, stocks in use/storage, additions, changes, recovery and spills; do not infer mineral oil or consumption from the hydraulic label. Check pre-cut cotton handling, dry-sheet handling/finishing and ventilation for actual cotton/wool lint or sized-paper particles. Record paired actual returns; independently characterize captured dry residues and final outdoor emissions. Every confirmed material, spent fluid, cleaning chemical, captured residue or emission needs a separately collected atomic identity/quantity, and each absence needs evidence; do not substitute wet fibre sludge or paper-machine dust factors.khadi-cotton-route, eu-pp-bref-2015
Allocation rules · 3

allocation_single_producthand_papermakingThis defined unit has one accepted product. Attribute its observed burdens to that output; wastes and internal returns do not become saleable co-products by assumption. If saleable co-products arise, collect their separate physical outputs and commission an allocation review before using this single-product model.eu-pp-bref-2015
allocation_physical_ledgersall physical balancesKeep unallocated mass/water/carbon and paired stage transfers separate from any environmental-burden allocation ledger. Never multiply physical co-product outputs or internal returns by allocation shares. No automatic negative credit for cotton cuttings, fibre recovery, rejects or wastewater.eu-pp-bref-2015
allocation_shared_utilitieselectricity and waterPrefer lot/stage submetering and segregated batches. For shared motors/baths, document attributable measured power-time, water events and serviced output; justify any remaining shared-service split and preserve total-service reconciliation.
