Context & Objectives
ADL is an airport operator present in three European countries.
In response to the EU targets for reducing GHG emissions in the aviation sector through the incorporation of SAF (2% in 2025 and up to 70% in 2050), ADL seeks to bring together local stakeholders around a bio-kerosene production chain.
Objectives
Astragal has been mandated to:
- Characterise the feedstock that could be used to produce the necessary amount of SAF.
- Validate the technology to convert the feedstock into bio-kerosene.
- Structure the value chain by bringing together: waste-suppliers, technology providers, operators and off-takers.
- Ensure regulatory compliance (e.g. ASTM D7566, RED II).
Our Approach
Waste mapping
Conducted an analysis of regional waste streams, collaborating with agricultural cooperatives, forestry associations and waste management companies.
Technology benchmarking
Evaluated conversion processes (FT-SPK, HEFA-SPK, BioTfuel®, etc.) and shortlisting based on carbon efficiency, scalability and CAPEX/OPEX.
Stakeholder alignment
Facilitated workshops with waste suppliers, technology partners and ADL to define roles, revenue models and risk allocation.
Regulatory check
Worked with DGAC to ensure SAF compliance.
Financing strategy
Structured a blended finance model, combining EU Innovation Fund grants, green bonds, and corporate PPAs. Secured €45M in initial funding, including €12M from regional investors.
Expected outcome
- Environmental: -80% GHG emissions vs fossil kerosene and diverted 50 kt/year of agricultural/forestry waste from landfill, creating a zero-waste scheme for the region.
- Economic: generated 120+ direct jobs and €10M economic value for the area.
- Leadership: positioned ADL as pioneer in waste-based SAF, influencing EU policy on advanced biofuels.
- Scalability: model replicated in two additional airports, with other waste inputs.
- Enhanced partnership: Enabled ADL to meet 30% of its 2030 SAF mandate, enhancing ESG profile and attracting sustainable aviation partners.
