Turning City Organic Waste into Carbon-Negative Aviation and Marine Biofuels

energyTestedTRL 5

Imagine taking the soggy food scraps and organic trash from a city and baking them into a dry, energy-dense charcoal. This charcoal is then processed using pure oxygen to create clean gas, which is further refined into jet fuel and ship fuel. To make it even greener, the leftover ash is used to soak up CO2 and turn it into building materials for cement.

The business problem

What needed solving

Hard-to-abate sectors like aviation and maritime struggle to find carbon-negative fuel sources. Simultaneously, the cement industry faces immense pressure to reduce CO2 emissions and find sustainable mineral feedstocks.

The solution

What was built

A full conversion chain including a torrefaction pre-treatment process, an oxygen-blown gasification system, and a Fischer-Tropsch reactor using 3D printed catalysts.

Business applications

Who can put this to work

Aviation
enterprise
Target: Airline or Aviation Fuel Supplier

If you are a fuel supplier dealing with strict carbon emission mandates — this project developed a process to produce kerosene from organic waste. This allows for the creation of carbon-negative aviation fuels to decarbonize hard-to-abate flight sectors.

Maritime
enterprise
Target: Shipping Company or Marine Fuel Producer

If you are a shipping operator dealing with high pollution costs — this project developed a method to produce alcohols for maritime use. It converts municipal organic waste into liquid fuels, reducing the carbon footprint of sea transport.

Construction
enterprise
Target: Cement Manufacturer

If you are a cement plant dealing with high CO2 emissions — this project developed a carbonation technique that fixes CO2 into gasification ashes. This creates new mineral feedstocks for cement, helping the industry move toward carbon negativity.

Frequently asked

Quick answers

What is the estimated cost or price of the produced biofuels?

Based on available project data, specific cost per liter or price points for the biofuels are not provided.

Is this technology ready for industrial scale?

The project aims to develop technologies from TRL 2 to 5. While it focuses on scalability, it is currently in the research and innovation phase rather than full industrial deployment.

How is the IP or licensing handled for the 3D printed catalysts?

Based on available project data, specific licensing terms are not mentioned, though the consortium includes 5 industrial partners to evaluate exploitation and scale-up feasibility.

What is the timeline for commercial availability?

The project period runs from 2022-10-01 to 2026-03-31, suggesting that technical validation will be completed by early 2026.

How does this integrate into existing waste management systems?

It integrates by using the Organic Fraction of Municipal Solid Waste (OFMSW) as a feedstock, converting heterogeneous wet waste into a homogenous solid biofuel via torrefaction.

Consortium

Who built it

The consortium is well-balanced for commercialization, featuring a 42% industry ratio with 5 industrial partners and 3 SMEs. With 12 partners across 8 European countries, the project combines academic research (2 universities, 4 research centers) with industrial application, ensuring that the transition from TRL 2 to 5 is grounded in market feasibility.
