# Peat briquettes

## 1. Scope and Applicability

This PCR covers binderless, uncarbonized peat compressed into dried fuel blocks. Its distinctive production requirements are moisture removal and mechanical compression, rather than peat extraction alone. Binder-containing mixed fuels, peat pellets, raw peat, peat coke, coal briquettes and horticultural growing media are excluded. The definition follows `un-energy-peat-products-2024`; classification identity follows `un-cpc-structure-2025`. The Chinese category title 泥炭压块 describes mechanically pressed fuel; UUID-bearing flow displays retain the database term 泥炭团块.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.ores-and-minerals-electricity-gas-and-water.coal-and-peat.peat-briquettes |
| classification_refs | CPC 3.0: 11052; `un-cpc-structure-2025` |
| covered_products | Binderless dried peat fuel blocks |
| excluded_products | Raw peat; peat pellets; peat coke; coal briquettes; binder-containing mixed fuels; growing media |
| representative_product | Accepted binderless peat briquette |
| production_route | Receive and prepare peat; dry; compress; cool and finish; wrap if applicable |
| market_state | Unburned solid fuel at factory gate, declared moisture, net mass excluding packaging |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Supply peat briquette fuel for downstream combustion |
| How much | 1 kg net accepted product at factory gate |
| How well | Declare as-sold moisture, ash, net calorific value and mechanical acceptance criteria; no universal heating performance is assumed |
| How long or cycle | One production reporting period; downstream combustion duration is outside this production dataset |
| reference_flow_link | briquettes |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Peat briquettes `0035aeea-b20b-4287-abac-d501f59c957f` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | Peat source and extraction boundary; site and year; binder absence; product moisture wet basis; ash and calorific-value test basis; briquette form and acceptance; thermal route; wrapping material; upstream drainage coverage |

Required qualifiers must be declared in the foreground data package. This mass reference is a production declared unit; comparisons of delivered heat additionally require measured calorific value and downstream efficiency.

## 4. Measurement and Unit Rules

Energy-unit conversion and fuel-specific calorific-value conventions follow `un-ires-2018`, paragraphs 4.23 and 4.33–4.38. Calorific value must correspond to actual moisture, composition and measurement state; gross and net bases must not be interchanged.

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass | kg | Use calibrated net weighing of accepted briquettes, excluding wrapping. All inventory amounts use per 1 kg reference flow. |
| moisture_basis | peat_feed; peat_fuel; briquettes | Mass | kg | Record wet-basis moisture for each weighed stream. Keep as-received and dry matter separate; do not substitute dry mass for as-sold reference mass. |
| electricity_conversion | prep_electricity; dry_electricity; press_electricity | Net calorific value | MJ | Convert electricity meter kWh to MJ using 1 kWh = 3.6 MJ. This is an exact unit conversion, not a fuel calorific-value estimate. |
| gas_volume | natural_gas_fuel | Volume | m3 | Declare meter temperature, pressure and reference-volume convention. Never convert gas volume into heat without measured supplier calorific value on the same basis. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Unagglomerated peat received at the briquetting plant; declared moisture and source |
| starting_condition_role | Foreground gate-to-gate production starting input |
| product_classification_scope | Binderless peat briquette fuel; CPC 11052 is classification context |
| recursive_input_rule | Purchased briquettes used as fuel require a supplier dataset; internal recirculation is measured for balance but is not a fresh input or co-product. Never recurse into this same dataset. |
| upstream_dataset_requirement | Link peat supply including extraction, land effects and drainage greenhouse gases; link utilities, fuel, packaging and waste treatment. UN guidance does not treat peat as renewable; IPCC wetland guidance identifies extraction-area and ditch activity requirements. |
| disclosure | Declare foreground start, upstream linkage and gaps, reporting period, peatland source, heat supplier or on-site fuel route, recycling, air location and waste fate. A plant-only dataset must not be labelled cradle-to-gate. |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| boundary_production | foreground | Include receiving, preparation, drying, pressing, cooling, finishing, actual wrapping, dust control and on-site thermal supply. Record each actual additional exchange separately by substance and state. | `un-energy-peat-products-2024` |
| boundary_upstream | peat_supply | Keep extraction and drainage burdens in a linked upstream dataset; do not assume burden-free peat or zero drainage emissions. IPCC national guidance informs upstream coverage, not a factory emission factor. | `ipcc-wetlands-2013` |
| boundary_internal | internal_transfers | Interstage peat and internally generated steam are internal transfers. Measure them for reconciliation without repeating external inputs; purchased heat excludes on-site generated heat. |  |
| boundary_use | downstream | Exclude customer delivery, final fuel combustion and consumer ash treatment; model these separately for heat-service comparisons. |  |

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| allocate_subdivide | shared_operations | First subdivide using line meters, weighed production and thermal-supply records. Shared heat generation is assigned by measured delivered heat; electricity by submeter readings. Document any remaining allocation and test sensitivity. | `ghg-product-standard-2011` |
| allocate_rework | peat_reject | Internal fines recirculation receives no avoided-product credit. Treat discarded fines and ash as waste unless documented sale establishes a co-product; subdivision precedes allocation by demonstrated physical relationships; use a disclosed, justified economic relationship only when the physical basis cannot be established or used. | `ghg-product-standard-2011` |

## 8. Foreground Data Collection, Calculation, and Quality Rules

`ghg-product-standard-2011`, Chapter 8 supports foreground activity collection and quality assessment; Chapter 9 supports subdivision and the allocation hierarchy. Its formal scope is GHG accounting; this PCR extends exchange-specific collection and disclosed data quality to water, materials and waste records. Knowledge of finished-product reference mass alone does not establish input or emission activity data.

### Data Collection Protocols

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalize_period | all inventory rows | Divide attributable reporting-period exchange totals by accepted net briquette mass in kg. The briquettes reference output is exactly 1 kg. | cp_prepare; cp_dry; cp_finish; cp_boiler | Each amount per 1 kg reference flow |  |
| water_balance | evaporated_water | Water evaporated equals water entering in peat and make-up minus water in products, rejects, liquid discharges and condensate leaving, adjusted for stock change. Prevent duplication of boiler moisture and plant drying moisture. | cp_prepare; cp_dry; cp_finish | Evaporated water per 1 kg reference flow |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| quality_identity | briquettes | Confirm binderless, uncarbonized peat block and declared moisture; exclude packaging from reference mass. | `un-energy-peat-products-2024`; cp_finish |
| quality_upstream | peat_feed; peat_fuel | Disclose peat extraction geography, source period and drainage emissions coverage. No carbon-neutral assumption. | `un-energy-peat-products-2024`; `ipcc-wetlands-2013` |
| quality_complete | all inventory rows | Reconcile dry matter, water, energy and rejected material. Record actual additional fuels, water discharges, packaging components and emitted species as individual exchanges with their own identity checks; do not hide them in a total-material row. Explain missing values and unresolved flow identities. | cp_prepare; cp_dry; cp_finish; cp_boiler |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validate_basis | all inventory rows | Require one consistent 1 kg net accepted briquette denominator, identical reporting periods and a linked collection protocol for each row. |  |
| validate_route | foreground | Verify binder absence, product state, actual thermal route and utility-source separation. On-site heat and purchased heat must not count the same burden twice. | `un-energy-peat-products-2024` |
| validate_balance | foreground | Require documented mass and moisture reconciliation, waste fate and emissions completeness. Unexplained deviations and missing pollutant quantities require further collection, not a zero substitution. |  |
| validate_identity | all inventory rows | Resolve or explicitly disclose every flow UUID gap; supplier background datasets must fit geography, year, technology and declared state. Do not substitute a coal ash flow for peat ash or nitrous oxide for nitrogen dioxide. |  |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | foreground_dataset |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Binderless peat briquette production; linked fuel-supply modelling with explicit extraction boundary |
| excluded_use | Binder-containing mixtures, carbonized peat, growing media, carbon-neutral claims, direct comparison of useful heat without downstream modelling |
| required_metadata | Site; year; peat origin; moisture; ash; calorific-value basis; route; reference unit; upstream links; wrapping; allocation |
| required_quality_disclosure | Meter and test coverage; seasonal coverage; uncertainty; unresolved UUIDs; missing upstream drainage data; absent external intensity benchmarks |
| update_trigger | Change of peat source, heat route, moisture specification, product acceptance, utility supplier or material emissions data |
