# Unfortified electric-fused calcium magnesium phosphate powder

## 1. Scope and Applicability

This method covers one physical product and route: virgin phosphate rock and serpentine flux, with separately metered quartz correction if required, electric-furnace melting, rapid water quench, dewatering, drying, milling, screening and release of unfortified glassy calcium-magnesium phosphate powder. The fusion/quench structure is supported by IFA Chapter 3.2.1.2 and Zennoh Figures 1–2; Yoorin confirms a marketed electrofusion fertilizer family. The product is a variable-composition phosphate-silicate glass matrix, not a single pure molecular salt or a dry physical mixture of pure oxides. References establish method feasibility, not a surveyed recipe, audited plant or current SKU. (`ifa-fertilizer-china-2009`; `zennoh-fused-phosphate`; `yoorin-phosphate-products`)

Exclude acidulated single/triple superphosphate, ammonium phosphates, N/P/K blends, untreated ground phosphate rock, basic steelmaking slag, phosphorus-smelting by-product slag, sludge-ash or other secondary-feed fusion, blast/cyclone/open-hearth primary fusion, added sulfur/boron/manganese or other nutrient fortification, and binder-granulated or formulated liquid products. These changes alter feed histories, gas/solid balances or formulation and require a separately assessed method. Powder variants with actual particle-size and solubility specifications can use this method; no agronomic dose or crop-yield equivalence is asserted.

The foreground includes actual receipt, burden preparation, electrical fusion, water circuits, finishing and pollution controls in one plant unit. Natural gas in finishing, diesel handling, hydrated-lime treatment, replaceable electrode/lining and individual packaging components are conditional measured exchanges, not mandatory recipes. Additional installed fuels, chemicals, packaging, transport modes or pollutants require their own atomic rows before a complete dataset is claimed. No steam/heat purchase is assumed: if supplied, collect pressure/state/return, net heat balance and provider reference convention in a separate row and utility unit. Numeric historical temperatures, energy use, ore grades, market guarantees, yields and emission limits are not defaults. (`jrc-lvic-aaf-2007`; `jrc-cww-2016`)

| classification_refs | CPC 3.0 `34629`, proposed `narrower`; the leaf includes other phosphatic products and does not define this method |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Supply of the specified unfortified fused phosphate fertilizer powder |
| How much | 1 kg net accepted commercial product |
| How well | Actual SKU assay and test methods for total/extractable P expressed as P2O5, Ca/Mg/Si basis, fluoride/trace contaminants, moisture, glass matrix, fineness and release acceptance |
| How long or cycle | One factory-gate release during the declared representative campaign; no crop service or lifetime claim |

| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | Actual SKU and batch; virgin phosphate-rock and serpentine origin/mineralogy; electric primary fusion; no added nutrient/binder or secondary-feed route; glass matrix; moisture and commercial mass basis; actual P2O5 assays and extraction method; Ca/Mg/Si/F/trace-element basis; particle size; product acceptance; packaging tare; plant/campaign; utility supplier conventions; water loops/outfalls; coproduct/waste destinations; allocation and model gate |

All qualifiers must be present in the concrete data package. The broad reference identity contains this physically defined subset and sets neither formulation nor nutrient concentration. It is not kg P, kg P2O5, pure calcium phosphate or another fertilizer route. Amount 1 kg is the normalization definition, not proof of field nutrient equivalence. Exactly one final product output uses this reference identity; stage handovers remain internal measurements.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| measure_reference | finished_product | Mass | kg | Weigh released commercial product net of package tare using calibrated scales; reconcile accepted lots and opening/closing product stocks for one campaign. No per-bag denominator. |
| measure_material | ore; serpentine; quartz; lime; electrode; refractory; oil; diesel; film; thread; waste outputs | Mass | kg | Record actual external mass, state, moisture and composition; distinguish wet parent mass, dry/active component and carrier water in explanatory ledgers without adding them twice. |
| measure_electricity | electricity | Net calorific value | MJ | The verified electric-flow property is named Net calorific value with an energy basis. Convert metered kWh to MJ by 3.6; collect actual supplier voltage/geography/mix/delivery and loss boundary separately. |
| measure_gas | gas | Volume | m3 | Meter and convert only to the provider-compatible gas volume at measured T/P, wet/dry composition and compressibility. Native secondary mass values do not establish density. Unknown conventions prevent a complete link. |
| measure_sacks | bag | Number of items | Item(s) | Count actual compatible sacks and defects; the flow is limited to 25 kg-format sacks. Separately weigh tare/material and measured fill for the mass ledger; never assume 25 kg fill or a generic sack mass. |
| measure_road | transport | Goods transport (mass*distance) | t*km | Sum actual loaded shipment tonnes times route kilometres, with provider load/backhaul boundaries; avoid fuel/transport or supplier-leg duplication. |
| measure_water_out | water_fresh | Volume | m3 | Use matched outfall volume; convert to water mass only with measured/traceable actual density/state and composition, not by confusing purchased water with emitted liquid. |
| measure_species | elementary outputs except water_fresh | Mass | kg | Match actual species, phase, origin and medium; retain dry/wet gas T/P/O2 reference conditions and compatible sampling flow. Resolve lump indicators before claiming species quantities. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Delivered virgin phosphate rock, serpentine and measured auxiliary supplies; supplying datasets cover extraction/beneficiation and delivery actually declared |
| starting_condition_role | Foreground process entry; not an assertion of zero upstream burden |
| product_classification_scope | Physical unfortified electric-fused powder subset; CPC context alone does not confer applicability |
| recursive_input_rule | Internal quench glass, collected dust and off-spec remelt are internal links measured at equal sending/receiving mass, not new purchased reference products |
| upstream_dataset_requirement | Compatible actual material and utility providers, verified quantity/state bases and transport; missing suppliers remain disclosed gaps |
| disclosure | Plant/stages/campaign; net release; feed and commercial moisture; utility modes; controls; recycle stocks; direct/sewer gates; residual destinations; allocation and exclusions |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| boundary_gate | fused_powder_unit | Include all actual receipt/crushing/burdening, electric furnace, quench/dewatering, drying/milling/screening, storage/dispatch, maintenance and air/water controls inside the chosen gate; stage meters remain separately retained. | `ifa-fertilizer-china-2009`; `zennoh-fused-phosphate` |
| boundary_supplies | external inputs | Connect actual mining/beneficiation, electrode/lining manufacture, utility generation and incoming delivery upstream; record shared-site subdivisions and each provider boundary. | `jrc-lvic-aaf-2007`; `jrc-cww-2016` |
| boundary_returns | physical links | Preserve equal internal transfer amounts and stocks for melt/quench glass, dust, rejected powder, water and recovered heat; internal circulation is not another purchased/emitted exchange or automatic avoided-product credit. | `jrc-lvic-aaf-2007` |
| boundary_outlets | environmental gates | Count collected dust/sludge as real external residuals only when leaving the unit; count air releases after control. For each liquid portion choose external treatment transfer or actual environmental outfall, retaining receiver, carrier water and pollutant load once. | `jrc-cww-2016` |
| boundary_downstream | supplied product | Field application, soil reactions, crop response, downstream nutrient blending and binder granulation are outside this production dataset. Producer promotional carbon or crop benefits do not establish credits. | `zennoh-fused-phosphate`; `yoorin-phosphate-products` |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| fused_powder_unit | Electric-fused phosphate powder production and actual controls | required | Declared virgin-rock/serpentine electric route; finishing utilities and package components conditional on actual equipment/supply | foreground production | finished_product; 1 kg net released powder |

Receipt/burden preparation → electric fusion → water quench → dewatering → drying → milling/screening → release/dispatch. Furnace, dryer, handling and mills feed their actual gas controls; liquid loops feed their actual collection/recycle/treatment/outfall. Retain separate stage mass, water, P/Ca/Mg/Si/F, carbon and heat ledgers. Unmodified glass moving between these stages is aggregated into this one foreground unit so the same material is not a second product output. (`ifa-fertilizer-china-2009`; `jrc-lvic-aaf-2007`)

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| allocation_physical | all physical streams | Preserve unallocated actual product, residue, water, gas and stock quantities and equal internal link endpoints. Product and co-product physical outputs are never multiplied by an allocation share. | `jrc-lvic-aaf-2007`; `jrc-cww-2016` |
| allocation_single | normal single-product unit | With one commercial fertilizer output, assign its attributable measured production and controls to that product; do not create fictional slag, nutrient coproducts or ash credits. Returned dust/glass/water has no external product function by itself. | `epa-lca-principles-2006` |
| allocation_multi | actual additional valuable output | Establish actual product/waste status, specification, receiver and function. If a commercial coproduct exists, add its separate measured physical output before modelling: first use subdivision or justified system expansion; otherwise a demonstrated causal physical relationship, or justified matched-period economic relation where physical causality is unavailable. No automatic wet-mass/equal share or avoided-product credit. | `epa-lca-principles-2006` |
| allocation_ledger | product burden reporting | Keep direct assignments, shared pools, factors summing to unity and sensitivity in a burden ledger separate from physical balances. Waste treatment stays attributed to its generating route; any credit requires explicit system/receiver evidence and absence of duplicate credit. | `epa-lca-principles-2006` |

Retain raw unallocated totals for one matched route, supplied state, grade and representative campaign, including all attributable failed and zero-accepted-output batches, start/stop, cleaning, idle, returns and rework. Reconcile opening/closing work in progress and finished stocks with accumulated inventory burdens, documenting carry-in/carry-out attribution without lost or duplicated burdens. Q is strictly positive final accepted net commercial production reconciled with release, dispatch and stocks; exclude final rejects and do not recount returned, reworked and reaccepted material. Apply normalize_campaign once to each reconciled raw exchange total. Row-specific conversion and calculation descriptions, including the Q division in road_service, denote that same normalization rather than another division. A complete campaign with Q <= 0 requires a justified wider representative period or an incomplete result.

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalize_campaign | all inventory rows | N = campaign external exchange in its declared unit / Q; Q is the same-campaign accepted net commercial powder mass in kg from cp_product. Preserve numerator, Q, stocks and stage measurements. Retain raw unallocated totals for one matched route, supplied state, grade and representative campaign, including all attributable failed and zero-accepted-output batches, start/stop, cleaning, idle, returns and rework. Reconcile opening/closing work in progress and finished stocks with accumulated inventory burdens, documenting carry-in/carry-out attribution without lost or duplicated burdens. Q is strictly positive final accepted net commercial production reconciled with release, dispatch and stocks; exclude final rejects and do not recount returned, reworked and reaccepted material. Apply normalize_campaign once to each reconciled raw exchange total. Row-specific conversion and calculation descriptions, including the Q division in road_service, denote that same normalization rather than another division. A complete campaign with Q <= 0 requires a justified wider representative period or an incomplete result. | cp_product; row-specific protocol | quantity per 1 kg reference flow | jrc-cww-2016 |
| material_components | wet feeds; lime; product; sludge | Component mass = measured wet parent mass × measured mass fraction. Dry/active matter, free carrier water and relevant structural water are explanatory parts, not extra purchased parent exchanges. | cp_material; cp_water; cp_product; cp_waste | physical component ledger | jrc-lvic-aaf-2007 |
| electricity_conversion | electricity | MJ = measured kWh × 3.6; this defined unit conversion is not a furnace or dryer consumption default. | cp_energy | compatible energy per reference kg |  |
| load_species | air and direct freshwater species | Retain raw period species mass before normalization. With compatible concentration and gas/liquid flow rate, integrate concentration × flow rate × the matched interval duration using explicit units. If the gas/liquid quantity is already an integrated volume, sum concentration × matched volume and do not multiply by duration again. Apply normalize_campaign once to the resulting raw period load. For element versus compound reporting, use measured speciation and the declared molar-mass ratio; total NOx or total F/P alone does not prove individual species. | cp_air; cp_effluent | raw period species mass before normalize_campaign | jrc-cww-2016 |
| particle_bins | pm25; pm10; pmover10 | Fine = PM2.5; middle = comparable PM10 − PM2.5; large = comparable total PM − PM10. Independently tested disjoint bins may replace differences. Negative/incomparable differences require review, not clipping; do not add nested totals. | cp_air | disjoint particle mass ledger | jrc-cww-2016 |
| gas_volume | gas | Provider-compatible volume is calculated from metered volume using the recorded actual and provider T/P absolute, wet/dry composition and compressibility convention with a traceable equation of state. No fixed density, NCV or default correction factor. | cp_gas | provider volume ledger and normalized m3 |  |
| carbon_balance | co2; geogenic_co2; co; methane; electrode | For each carbon origin: measured inputs = carbon in products/residuals + carbon in actual emitted species + stock change, with stated uncertainty. Oxidised fossil electrode carbon converted to CO2 uses 44/12 only for the CO2-assigned carbon; use corresponding molar ratios for CO/CH4. Mineral carbonate carbon and any real biogenic carbon stay separate and are not deleted from LCI. | cp_material; cp_maintenance; cp_air; cp_stage | origin-specific unallocated carbon ledger | jrc-lvic-aaf-2007 |
| phosphorus_basis | ore; finished_product; phosphate | P2O5 assay is an analytical expression, not a pure oxide addition. Record total and extractant-soluble fractions and wet/dry denominator separately. PO4 mass from a measured phosphate-as-P load uses molar mass PO4 / molar mass P only after confirming that phosphate fraction; do not treat all total P as PO4. | cp_material; cp_product; cp_effluent | analytical P ledger and speciated load | zennoh-fused-phosphate |
| water_energy_balance | stage links; water; water_air; water_fresh | Reconcile external free water, feed/reagent water, structural water release and combustion water with retained product/sludge moisture, vapour, liquid exits and stocks; reconcile furnace/finishing electricity/fuel with measured useful duty, cooling/quench heat and losses. Report residuals without invented yield, evaporation or steam credit. For actual neutralisation, precipitation or other reactions, retain independently evidenced water formation/consumption and dry-species formation/consumption terms from measured chemical forms and reaction extents. Complete-boundary total mass and elements conserve; individual water or dry species need not. Do not infer those reaction terms by forcing a residual, COD or assumed formula to close. | cp_water; cp_gas; cp_energy; cp_stage | physical water/H/O and energy ledgers | jrc-lvic-aaf-2007 |
| road_service | transport | Road service = sum(shipped kg / 1000 × actual leg km), before dividing by Q; demonstrate actual load/backhaul provider basis and keep included upstream legs from being counted again. | cp_transport; cp_product | t*km per reference kg |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| dq_identity | product and feeds | Require measured unfortified glassy powder and virgin-rock/serpentine electric route; neither a category label nor a broad fertilizer UUID establishes composition or nutrient basis. Resolve contrary CAS/route fields before linking. | actual SKU, mineralogy, assays and process diagram |
| dq_measurement | all rows | Calibrated units, compatible supplier/receiver basis, matched campaign Q and representative time coverage; record uncertainty and independent stage readings. No borrowed purity, recipe, energy, yield or default emission rate. | cp_product; cp_stage; row protocols |
| dq_balances | physical streams | Keep unallocated mass, water/H/O, P/Ca/Mg/Si/F, trace-element, carbon-origin and energy ledgers, including dust capture, electrode oxidation, lining wear, coproducts, liquid transfers and stocks. Report residuals with uncertainty rather than inventing closure. | cp_stage; jrc-lvic-aaf-2007 |
| dq_completeness | active actual exchanges | Capture normal/start/stop, cleaning, maintenance, diffuse dust and every relevant species; add actual extra chemicals, packaging wastes/filter media, transport or controls individually. Missing measurements or identities remain unknown, not zero. | stream register; cp_air; cp_effluent |
| dq_source_scope | all sources | IFA is a historical industry synthesis, Zennoh a distributor handbook and Yoorin a producer family; they do not establish universal quantities. JRC general balance/monitoring rules apply only in their stated scope, not other fertilizer chapters or legal limits. EPA is general historical LCA guidance, not a current standards-compliance claim. | source sections and actual applicability |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| validate_identity | reference and feeds | Demonstrate the stated virgin-rock/serpentine electric fusion and unfortified glassy powder scope; excluded feeds/routes cannot be waived with a broad fertilizer name. Declare whole commercial kg separately from analytical P/P2O5. | `ifa-fertilizer-china-2009`; `zennoh-fused-phosphate` |
| validate_reference | finished_product | Exactly one completed final reference product output; denominator and collection aggregation are per 1 kg net commercial release in both languages. Equal internal handovers remain physical stage records. | `jrc-lvic-aaf-2007` |
| validate_supply | utilities and components | Verify actual energy/volume/count properties, gas conditions, electricity provider, package inclusions and wet/active/water bases. Missing supplier conventions prevent a complete background link even with a valid flow identity. | `jrc-cww-2016` |
| validate_species | elementary releases | Require true species, carbon origin and air/freshwater medium. Do not substitute F2 for HF/fluoride, total NOx for NO or NO2, N2O for NOx, dissolved solids for suspended solids, or correction flows for real emissions. Keep PM bins and captured/emitted mass disjoint; real biogenic CO2 remains in LCI. | `jrc-cww-2016` |
| validate_physical | balances and allocation | Reconcile physical outputs and equal internal links before burden allocation; no reduced physical coproduct output, disappearing water, invented carbonate conversion or duplicate dust/wastewater burden. | `jrc-lvic-aaf-2007`; `epa-lca-principles-2006` |
| validate_completeness | concrete dataset | Every active actual row needs quantity evidence, identity decision, property/unit, state, provider/receiver and route applicability. Unresolved identity, lump-only species assay, unknown quantity or unsupported conversion prevents a complete dataset claim; method authorship is not scientific approval or site verification. | `jrc-cww-2016` |

## 10. Published Dataset Profile

| --- | --- |
| dataset_role | Foreground production dataset for the specified unfortified electric-fused powder |

| excluded_use | Generic all-phosphatic-fertilizer average; kg nutrient without explicit assay conversion; excluded fusion/acidulation/secondary-feed routes; direct field-use impacts or crop/climate-credit claims |
| required_metadata | SKU, feed origins/assays, route, glass matrix, moisture/fineness, acceptance, Q/campaign, providers, utility conventions, packages, treatment/outfalls, stocks, coproduct/waste status, allocation and system gate |
| required_quality_disclosure | Actual measurements and uncertainty; source applicability; unknown or missing quantities/identities; background compatibility; closures and residuals; scientific-review state |
