Nathalie Devriendt

Biomass & Energy expert

With her consultancy firm ‘In den Roden Schilt consulting’, Nathalie works towards a sustainable future using biomass (residual) flows. Nathalie combines her technical, economic and policy expertise to turn innovative ideas into feasible projects.

Are you looking for:

  • Project feasibility
  • Development of future vision
  • Innovation projects
  • Education and training


Nathalie has been active in the biomass world since 2001. She has closely followed and co-directed the evolutions in the use of biomass:

  • From bioenergy to biobased chemistry and biomaterials
  • From linear to circular use of biomass
  •  From import biomass to local use of biomass

In guiding biomass projects, Nathalie will always seek the balance between what is already possible today and in what direction it will evaluate in the future. So, current projects using biomass will always look beyond energy generation. Recently, Nathalie has extended her expertise from biomass to energy, to its use in chemistry but also as feedstock for new bio-based materials.

Where needed, Nathalie combines her expertise with other experts from her broad network.

Bio-enthusiasm for your project

About Nathalie

Nathalie Devriendt graduated in 2001 as Master in Bio-engineering at the KULeuven. Her first work experience in biomass was as an engineer at ‘Seghers Solids and Air’, a constructor of bio-energy installations. From 2002 to 2016 she worked as a researcher and later as a project manager on biomass at Vito.

Since 2017 Nathalie is active as an independent consultant.

Since 2018, Nathalie is also part-time active at ProNatura to look for innovative solutions for the green waste generated by green landscaping and green maintenance.

Turning green waste into raw material for new materials

Symbiosis pays off: “Turning green waste into raw materials for new materials”, June 2020.
“As a social economy company, Pro Natura dries and refines its green waste (grass, Japanese knotweed, reed, etc.) into raw materials for new materials. Thanks to the symbiosis platform, we come into contact with companies that dare to think outside the box and start working with our natural fibres.” says Nathalie Devriendt of Pro Natura.

Grassification Interreg project

In this Interreg project, the conversion of roadside clippings to materials is being tested (2018-2021). The adaptation of cutting protocols, the pretreatment of the grass clippings and the reprocessing into high-quality fibres will be supervised by Nathalie.

Since 2008, Nathalie has been chairing the working group on bio-CHP within Cogen Flanders.
During the annual CHP training, Nathalie takes care of the part ‘Biomass as energy source in a CHP’.
