New waste technology will deliver liquid fuels and reduce CO2 emissions

CircFuel is a Danish innovation project established to develop technology for reducing CO2 emissions from cement plants, and at the same time produce fuel through pyrolysis technology. Geminor will contribute to the project with both waste fractions and market experience.

The Technical University of Denmark (DTU) and the technology company FLSmidths are the initiators behind the project by the name of CircFuel. The project aims to use the energy in cement production to convert organic waste into hydrocarbons in a pyrolysis process. CircFuel will run for four years and has a total budget of 27 million Danish kroner (Euro 3.6 million).

In practice, the CircFuel project is a further development of FLSmidth’s patented waste treatment reactor, which today makes it possible to use waste as an alternative fuel in cement factories. The new technology will make it possible to use waste not only as a source of energy for cement production, but also to produce liquid fuel through pyrolysis. This fuel can be used as a replacement fuel in the transport sector and contribute to a reduction in the use of fossil fuels worldwide.

Geminor, which is already involved in projects such as CO2 capture and chemical recycling of plastics, will be providing the CircFuel project with both expertise and waste fractions, says CEO at Geminor, Kjetil Vikingstad.

– Geminor will provide waste samples for the experiments and share expertise in relation to the various fractions being tested in the project. Ensuring access to the right waste, and contributing with knowledge of the market mechanisms, will also be important contributions to this project, says Vikingstad.

Producing multipurpose fuel

In this project, the use of the liquid pyrolysis product will be investigated via three different process routes. This includes the direct use of the liquid fuel, a partial catalytic upgrade located on the cement plant, and an external full hydrogenation of the pyrolysis oil.

This is a project that coincides well with Geminor’s focus on sustainable recycling, says Vikingstad.

– The production of cement is among the most polluting industries in the world today. Precisely for this reason, CircFuel is an important project that can make a significant difference in terms of CO2 emissions in the future. The technology also has the potential to improve the economy of the cement producers, and reduce both international landfills and the use of fossil fuels, concludes the Geminor CEO, Kjetil Vikingstad.
