ENADT is taking the initiative to develop a highly efficient biomass gasification demonstration plant with Fischer-Tropsch reactor coupling, which can be fed with organic (plastic) waste and recycle it into clean burning sustainable aircraft fuel (EKOrosene®) reducing net greenhouse gases.

Jet fuel consumption

Aviation in Europe requires approximately 80,000,000 tonnes of jet fuel (kerosene) annually. The Netherlands requires approximately 4,700,000 tonnes per year. 

In three years’ time, aircraft in Europe will be required to fly partially on sustainable fuel. The Dutch government is taking the lead in introducing the European blending obligation for sustainable aviation fuels. The blending obligation can reduce aviation emissions in the short term and encourages the development and production of alternative fuels for aviation.

Blending obligation

In the draft Sustainable Aviation Agreement, the Minister agreed that by 2030 14% of the jetfuel used in aviation in the Netherlands will be sustainable and by 2050 the entire fossil kerosene requirement of aviation will be replaced by sustainable alternatives.

In order to achieve the 14% blending rate, approximately 660,000 tonnes of sustainable fuel must be produced annually. 

The current production of biofuels is insufficient to meet the 14% standard in 2030. On the one hand there is insufficient feedstock available for the current form of biofuel production, and on the other hand other alternatives based on direct air capture are simply not yet scalable and far too expensive. It is therefore essential to quickly find an alternative feedstock that can serve as a basis for a cost-efficient and climate-neutral production of sustainable aviation fuel in the desired volumes at an acceptable price. 

Well, there is an alternative feedstock already available in large quantities!

Increasing population leads to an increase in plastic waste which is a big issue in every country. The plastic waste can be managed by landfill and incinerating. The disadvantages of landfill and incinerating are carbon dioxide emission. Although plastic waste can be reused and recycled, in the end it will be garbage or become non-recyclable. In order to add value of plastic waste, the conversion of plastic waste to synthesis gas is the way forward!

Waste streams

The volume of (plastic) waste streams in the Netherlands that are suitable for use as feedstock for the production of synthesis gas (syngas), is approximately 1,700,000 tonnes. The gasification of the (plastic) residual waste streams into Syngas(a combination of carbon monoxide and hydrogen) from which sustainable aviation fuel and other fuels and chemicals can be produced via the Fischer–Tropsch process[1]– a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen into liquid hydrocarbons – is the ultimate solution for the ever growing waste streams and the fossil fuel use within the Aviation industry. 

Production of EKOrosene

The EKOrosene production process consists of four stages: 

  1. In the first stage household and commercial waste is collected and treated so that it can be processed in the gasification reactor.
  2. In the second stage synthesis gas, a mixture of hydrogen and carbon monoxide, is manufactured from organic waste by gasification. Impurities are removed from the syngas and natural hydrogen is added. 
  3. A third stage converts the enriched synthesis gas into liquid hydrocarbons using a catalyst. In this stage, a liquid is formed which looks and feels like wax at room temperature. 
  4. The final stage is cracking and isomerisation, which “tailors” the molecule chains into products with desired properties. This yields high-quality ‘clean’ liquids such as jet fuel (kerosene), diesel, and nafta.

Similar initiatives are taking place in the UK, California and Canada. The process of making syngas out of waste is technically matured and scalable, so is the production of syngas into fuel. ENADT is taking the initiative to develop a demonstration plant in the Amsterdam region for the production of EKOrosene (sustainable jet fuel) by means of a biomass gasification plant with Fischer – Tropsch coupling, which is fed with organic waste streams and natural hydrogen. ENADT is planning to start production in 2022.
