Waste to Jet. Future Ready

Recycling Carbon for Clean Aviation

Step 01

Residual waste & renewable electricity

Green Birch will use residual waste and renewable electricity as its main feedstocks. The residual waste is what remains after all fractions suitable for material recycling have been separated out, similar to the waste that today is used to produce district heating and electricity at several sites in Sweden.

Step 02

Gasification

Using gasification technology, where waste is broken down at high temperature in the absence of air, the residual waste is converted into a synthesis gas (syngas).

Step 03

Methanol synthesis

In the next step, the synthesis gas is converted into methanol in a catalytic process. Here, additional green hydrogen produced from renewable electricity is added to increase the overall carbon utilisation and fuel yield.

Step 04

Methanol-to-Jet

The methanol is then upgraded to jet fuel through a Methanol-to-Jet process, creating a high-quality SAF that can be used as a drop-in replacement for fossil jet fuel.

Step 05

Transport & use

The finished product is transported by rail and fuel logistics to offtake partners and airports, where it is blended into the jet fuel pool and used in existing aircraft.

Step 06

Heat & circularity

The process also generates surplus heat that can be used for district heating. The planned Green Birch facility is designed for high resource efficiency and contributes to a circular, renewable economy.

Site

Umeå Eco Industrial Park at Dåva

The Green Birch plant is planned at Umeå Eco Industrial Park at Dåva, Umeå’s largest industrial development area in the region of Västerbotten in northern Sweden. The park is being developed as a world-class hub for circular green innovation, recycling and energy.

Locating the project at Dåva provides access to established waste handling infrastructure, district heating networks and electricity, as well as strong road and rail connections. This enables industrial symbiosis with neighbouring facilities and supports efficient use of energy and materials.
