Understanding Waste Disposal Emissions
Waste generated in operations covers emissions from third-party disposal and treatment of waste generated in your organizationβs owned or controlled operations. Under ISO 14064-1 Category 4, this includes:- Landfill disposal: Emissions from decomposition of waste in landfills
- Incineration: Emissions from burning waste (with or without energy recovery)
- Recycling: Emissions from processing waste for material recovery
- Composting: Emissions from biological treatment of organic waste
- Waste transport: Emissions from transporting waste to treatment facilities
Category 4.2 vs Other Waste-Related Emissions
- Category 4.2: Waste generated in your operations, treated by third parties
- Category 5: End-of-life treatment of products you sell (downstream)
- Category 1: On-site waste treatment at facilities you own/control (direct emissions)
Prerequisites
Before starting, ensure you have:- Dcycle API credentials (get them here)
- Completed ISO 14064 Tutorial
- At least one facility created
- Waste manifests or invoices from your waste management provider
Data Map: Category 4.2 Requirements Overview
Understanding Waste Codes
LER Codes (European List of Waste)
The LER code (also called LoW code) is a 6-digit code that identifies the type of waste according to the European List of Waste. Common examples:Hazardous WasteLER codes ending with an asterisk (*) indicate hazardous waste. These typically have different emission factors and require special handling documentation.
RD Codes (Treatment Methods)
The RD code identifies the treatment or disposal method. It consists of R (Recovery) or D (Disposal) followed by a 2-digit number: Recovery Operations (R codes):
Disposal Operations (D codes):
When RD Code is UnknownA single LoW/LER code can be associated with multiple treatment methods (RD codes), each with different emission factors. If the RD code is not provided, Dcycle automatically uses the average emission factor across all possible treatment methods for that waste type.For more accurate emissions calculations, provide the RD code when known from your waste management documentation.
Emission Factors
Dcycle uses waste emission factors derived from the IPCC Guidelines for National Greenhouse Gas Inventories:IPCC Waste Methodology
IPCC Waste Methodology
Intergovernmental Panel on Climate Change (IPCC)
- Default emission factors for solid waste disposal sites (landfill)
- Methane (CHβ) emissions from anaerobic decomposition
- Waste incineration factors for COβ and NβO
- Covers all standard waste categories and treatment methods
Treatment-Specific Factors
Treatment-Specific Factors
By disposal/recovery method:
- Landfill (D01): CHβ from organic decomposition, based on IPCC default methane correction factors
- Incineration (D10/R01): COβ from fossil carbon content + NβO from combustion
- Recycling (R03-R05): Processing emissions, often offset by avoided virgin material
- Composting (R10): CHβ and NβO from biological treatment
Transport Emissions
Transport Emissions
Waste transport to treatment facility:
- Based on average truck emissions (Ecoinvent)
- Calculated using:
(quantity_kg / 1000) Γ distance_km Γ transport_ef - Default transport EF: ~0.1 kg COβe per ton-km
Recording Waste Data
Create Waste Records
π Data Map: Single Waste Record
π Data Map: Single Waste Record
Where to get this data:
- LER code: Waste manifest or transfer note from waste collector
- RD code: Waste management invoice or certificate
- Quantity: Weighbridge ticket or estimated from container size
- Distance: Address of treatment facility (or ask waste provider)
Common Waste Types Example
Track multiple waste streams from your facility:Upload Waste Documents (PDF)
Dcycle can automatically extract waste data from PDF invoices:Supported Waste Invoice FormatsDcycleβs OCR can extract data from standard waste transfer notes and invoices, including:
- Spanish DI (Documento de IdentificaciΓ³n)
- Standard European waste manifests
- Various waste management company formats
Bulk Upload Waste Records
For organizations with many waste streams, use CSV upload:CSV Format
CSV Notes:
quantityis always in kilograms (kg)kms_to_waste_centeris optional but recommended for accurate transport emissions- Use the correct facility_id for each waste record

Analyze by Treatment Method
Best Practices
1. Track All Waste Streams
2. Prioritize High-Impact Waste
3. Track Diversion Rate
Troubleshooting
Issue: LER Code Not Found
Issue: Unknown Treatment Method
Issue: Category 4.2 Seems Too Low
Next Steps
