Overview
What Is Spent Bleaching Earth Oil (SBEO)?
Spent bleaching earth oil (SBEO) is a residue generated during the bleaching stage of vegetable oil refining. Bleaching clay (fuller's earth) is used to remove colour pigments, oxidation products and trace contaminants from crude palm, rapeseed or sunflower oil. The spent clay retains 20–50% of its weight in trapped oil — this extracted oil is SBEO.
SBEO is classified as an Annex IX Part A advanced feedstock under EU RED III — the highest regulatory category, ahead of Annex IX Part B (UCO, animal fats). Part A feedstocks are uncapped and double-counted, meaning every tonne of SBEO-derived biofuel counts twice towards EU renewable energy mandates with no blending ceiling.
SUAT Fuels sources SBEO directly from palm and vegetable oil refineries in Southeast Asia and Europe, with full ISCC EU chain-of-custody documentation from extraction point to delivery.
Key Advantages
Why Spent Bleaching Earth Oil (SBEO) for Renewable Fuels?
Annex IX Part A — Highest Category
Uncapped and double-counted under EU RED III — the most valuable regulatory classification. No blending ceiling unlike Annex IX Part B feedstocks.
>85% GHG Savings
More than 85% lifecycle GHG reduction vs fossil diesel. Per tonne processed, approximately 2.5 tonnes CO₂e prevented vs virgin oil baseline. Premium value for mandate compliance.
Circular Economy Feedstock
SBEO avoids costly waste disposal and converts a refinery waste stream into high-value biofuel feedstock. Supports circular economy reporting for refiners.
Growing Scarcity
As advanced biofuel demand grows, Annex IX Part A feedstocks like SBEO command increasing price premiums. Forward supply agreements are strongly recommended.

Compliance
Regulatory Status & Certifications
EU RED III — Annex IX Part A (Highest Category)
- Classified as Annex IX Part A advanced feedstock — uncapped and double-counted with no blending ceiling
- Qualifies as a refining residue under EU Waste Framework Directive — not a primary production output
- ISCC EU certification required for chain-of-custody — SUAT holds active ISCC EU and ISCC CORSIA licences
- Eligible for advanced biofuel production under EU RED III, national mandates and ReFuelEU obligations
- Also classified as EU Waste Framework Directive waste — subject to waste shipment regulations for cross-border movement
End Uses
Applications
FAME Biodiesel
Blendable with other feedstocks (up to 30%) in standard FAME transesterification. High FFA content handled via acid esterification pre-treatment.
HVO Pre-treatment Feed
After lipid extraction and pre-treatment, SBEO oil fraction fed into HVO hydrotreating units. Produces renewable diesel or SAF blendstock.
Advanced SAF
As Annex IX Part A, SBEO-derived SAF qualifies for highest incentive value under ReFuelEU and CORSIA. Increasingly targeted by SAF producers.
Industrial Combustion
Unrefined SBEO used as industrial burner fuel substitute for heavy fuel oil. Lower calorific value but near-zero waste alternative.
Supply Geography
Origins & Availability
Primary supply from Southeast Asian palm oil refineries (Malaysia and Indonesia account for the largest volumes globally). Secondary sources include European vegetable oil refineries processing rapeseed, sunflower and soybean oils. South American soybean oil refineries are an emerging supply source. SUAT coordinates extraction contracts directly with refinery operators.
