Overview
What Is Animal Fats Category 1 & 2?
Category 1 and Category 2 animal fats are rendered lipids derived from slaughterhouse and processing plant by-products deemed unfit for human or animal consumption. Under EU Animal By-Products Regulation (ABPR No. 1069/2009), Category 1 materials come from specified risk materials (SRM) and Category 2 from fallen stock and condemned carcasses.
These materials must be processed by licensed rendering plants to produce technical-grade fat, which is then used as a high-energy biofuel feedstock. Due to their waste classification, they qualify as RED III Annex IX Part B feedstocks — eligible for double-counting towards EU renewable energy mandates.
SUAT Fuels sources Category 1 & 2 fats directly from EU rendering plants and LATAM suppliers, providing full ABP compliance documentation alongside ISCC chain-of-custody certification.
Key Advantages
Why Animal Fats Category 1 & 2 for Renewable Fuels?
Annex IX Part B — Double Counted
Full double-counting eligibility under EU RED III. Subject to 1.7% transport cap alongside UCO. Higher regulatory value than Cat 3 or conventional fats.
74–82% GHG Savings
Lifecycle GHG reduction 74–82% vs fossil diesel (GREET model, tallow pathway). Qualifies for ISCC CORSIA SAF sustainability claims.
High Energy Density
Calorific value 35–37 MJ/kg. High cetane precursor content — excellent for HVO and HEFA-SAF co-processing. Low moisture reduces pre-treatment costs.
Full ABP Compliance Docs
We manage all ABP regulatory paperwork: species declarations, transformation standards, TRACES transport certificates and EU import health certificates.

Compliance
Regulatory Status & Certifications
EU RED III — Annex IX Part B & ABP Regulation
- Classified as Annex IX Part B waste feedstock — double-counting towards EU renewable energy targets
- Regulated under EU Animal By-Products Regulation (ABPR) 1069/2009 — Cat 1 and Cat 2 materials require licensed rendering and cannot enter food/feed chains
- ISCC EU chain-of-custody certification required. SUAT holds active ISCC EU and ISCC CORSIA licences
- Subject to 1.7% transport energy sub-cap under RED III (shared with UCO and other Part B feedstocks)
- TRACES transport documentation required for intra-EU movements of Cat 1 & 2 materials
End Uses
Applications
HVO / Renewable Diesel
Major HVO plants (Neste, ENI, Preem) process Cat 1&2 fats as primary co-feedstock. High energy density, compatible with existing HEFA infrastructure.
HEFA-SAF
Eligible feedstock for CORSIA and ReFuelEU SAF production. Growing demand from SAF producers seeking non-UCO Annex IX Part B supply.
FAME Biodiesel
Requires acid esterification pre-treatment for high-FFA batches. Blended with UCO or virgin oils to manage FFA levels in FAME production.
Co-processing
Direct injection into petroleum refinery hydrotreaters. Renewable content credited to the diesel pool under co-processing certification schemes.
Supply Geography
Origins & Availability
Primary EU supply comes from EFPRA-member rendering plants in Spain, Ireland, Germany and Poland. South American origins (Brazil, Argentina) are growing exporters following increased cattle processing volumes. SUAT provides origin-specific CoC documentation for all supply chains.
