1. Scope and Applicability

This environmental LCA manufacturing method covers unmedicated, non-sterile hydrophilic pure-cotton wool supplied as a wrapped roll, made from externally supplied virgin ginned cotton lint by alkaline scouring, hydrogen-peroxide bleaching, washing/rinsing, conditional acid finishing, hydro-extraction, drying, lapping/carding, rolling/cutting, packing and quality release. The declared base route purchases steam and electricity and sends wastewater to external treatment. Record actual fibre grade and supply moisture, bleaching/finishing chemistry, drying energy, outsourced operations and each packaging component. The government roadmap supports process decomposition; the independently specified GIMA 34838 roll supports a real non-sterile pure-cotton market state, not proof of GIMA factory chemistry or packaging composition.

Exclude woven gauze, bandages, cotton balls/pads, synthetic or blended fibre, linters/recycled-cotton substitution, drug impregnation, composite/adhesive dressings and sterile products. A different fibre, bleach chemistry, supplied form, sterility or packaging architecture needs separate applicability and inventory assessment; CPC 35279 is broader than this method. No clinical application instruction, efficacy equivalence, absorption-capacity default, service-life default or sterilization operating parameter is supplied. The roadmap also discusses gamma treatment/sterile cotton; those statements cannot be transferred to this non-sterile product. Actual treatment is never erased: if present, retain its supplier, materials, energy, transport, losses and releases and reassess the supplied-state boundary before applying this method.

The reference gate is new positive quality-released output after the declared packing and acceptance steps. Q is not dispatch quantity. Count each physical lot once; returns and reacceptance do not create new production. Missing required qualifiers makes a foreground package incomplete. The broad native reference identity and all its limits are retained in the terminal flow card.

boundary_gateproduction and finished goodsProduction ends at new quality release. Do not add closing finished stock of the same released Q as another production output. Maintain opening/closing finished stocks and carried burdens in the separate storage/dispatch ledger; preserve actual storage, packing, handling, freight and returns burdens. When combining ledgers, cancel internal product and burden handoffs. A delivery-gate dataset must use actual net deliveries and matched opening/closing finished inventory with carried burdens; it cannot relabel Q or assume release equals delivery.
boundary_statesupplied stateNon-sterile does not justify deleting actual treatment. Record any real subcontract treatment and its losses; sterile or medicated output is outside this scope until independently reassessed.

Calculation Rules

rule_idApplies toFormula or ruleInputsOutputsource_ids
raw_cohortall manufacturing numeratorsFor each exchange, retain complete raw consumption/burden, including failed/zero-output and repeated rework. Attribute A_i = raw period burden + opening WIP carried burden - closing WIP carried burden for the same product, route and supplied-state cohort; substantiate actual transfer records. Direct raw physical exchanges and carried historical burdens remain separately traceable; do not add carried mass as a second purchase. Do not subtract finished stock already counted in Q.raw_period; opening_WIP; closing_WIP; cp_materials; cp_utilities; cp_wasteA_i
normalize_releaseall included inventory rows except terminal referenceq_i = A_i / Q; Q = unique positive newly quality-released net cotton mass in kg for the matched cohort from cp_release. First convert raw records once to each row unit. This is the only normalization: inventory amount expressions, protocol aggregation references and this rule describe the same report operation, not sequential divisions. For storage_dispatch use its separately reconciled A_i attributable to that same release cohort and Q, retaining any unfinished residence as a disclosed scope limit. Q <= 0 cannot produce a normalized released-product dataset; retain its burdens for the matched causal cohort.A_i; Q; cp_release; cp_storageq_i
supply_subledgerssolutions, cotton moisture and waterFor each whole purchased formulation m, constituent mass = m times its independent assay fraction. For cotton, dry mass = wet mass times (1 - measured moisture fraction). Carrier water, active matter and fibre dry mass are subledgers, not extra external inputs. Independently support actual species and any reaction-water formation/consumption; keep phase/free/bound-water changes distinct. No COD or closure-residual fitting.whole_supply_mass; assay_fraction; measured_moisture; cp_balanceconstituent_and_water_subledgers
finished_ledgerstorage and dispatch reconciliationClosing finished stock = opening finished stock + new release + actual returns - actual dispatch - disposal, with other documented physical movements shown explicitly. Carry historical burdens with the same lots. Returns/reacceptance do not increase new release. Integration cancels the release-to-storage internal handoff and its burdens. Actual net delivery, if separately reported, excludes undispatched stock and is a different denominator requiring its own matched carried-burden calculation.cp_release; cp_storage; stock_movements; carried_burdensreconciled_finished_ledger

Collection cannot already divide by Q. Do not add closing finished goods to new release or count returns twice. Separate warehouse/dispatch owner and retained loads are mandatory when included.
validate_balancemass, water and environmental exchangesCheck physical mass/elements and moisture on stated bases, using independent actual species/reaction evidence. Whole formulations cannot be duplicated as constituent purchases; integrated volume cannot be multiplied by time again. Unknown reaction water cannot close an unknown outlet by the same residual. Retain treatment/provider evidence and uncertainty rather than claim closure from COD.

System boundary rules · 3
Rule IDApplies toRuleSource IDs
boundary_operationsmanufactureInclude actual opening/cleaning, scour, bleach, all rinses/finishing, extraction, drying, carding, conversion, QC, packing, internal movement and cleaning, including failed runs and rework. Keep purchased heat/electricity and actual outsourced operations once. An onsite boiler, onsite effluent treatment or other energy route requires explicit process expansion with separate fuel, water, chemical, waste and elementary exchanges, not omitted loads.msme-cotton-wool-roadmap
boundary_gateproduction and finished goodsProduction ends at new quality release. Do not add closing finished stock of the same released Q as another production output. Maintain opening/closing finished stocks and carried burdens in the separate storage/dispatch ledger; preserve actual storage, packing, handling, freight and returns burdens. When combining ledgers, cancel internal product and burden handoffs. A delivery-gate dataset must use actual net deliveries and matched opening/closing finished inventory with carried burdens; it cannot relabel Q or assume release equals delivery.
boundary_statesupplied stateNon-sterile does not justify deleting actual treatment. Record any real subcontract treatment and its losses; sterile or medicated output is outside this scope until independently reassessed. Exclude clinical use and end of life from this manufacturing dataset and disclose them.gima-nonsterile-cotton-roll
Allocation rules · 2
Rule IDApplies toRuleSource IDs
allocation_separateshared equipment and utilitiesSeparate SKU/route/sterility/packaging cohorts first. Use meters or documented physical causation for shared loads; retain failed and zero-output runs in their causal cohort. No default yield, inspection loss or economic allocation factor is assigned.jrc-ilcd-2010-allocation
allocation_reworkrework, waste and coproductsInternal recirculation cancels on integration and adds its actual repeated processing burdens. Returned/reaccepted cotton is not new production. Cotton rejects are waste unless an evidenced saleable coproduct specification and allocation are declared; no avoided-product credit by assumption. External treatment and recycling are counted once under the declared accounting convention.
