Database for the physico-chemical composition of (treated) lignocellulosic biomass, micro- and macroalgae, various feedstocks for biogas production and biochar

Phyllis is a database containing information on the composition of biomass, macro- and micro-algae, feedstocks for biogas production, biochar and torrefied biomass. Phyllis provides data for individual materials or average values for a group of materials.

Phyllis is an initiative from ECN and the database has been combined with the BIODAT database from the PHYDADES project. Phyllis is maintained by TNO Biobased and Circular Technologies. At present it contains around 3000 data records. Phyllis will be updated and extended regularly.

You can get answers to questions such as:

  • What is the average sulphur content of wood?
  • What is the ash content of willow?
  • What is the average calorific value of chicken manure?

You may also contact TNO Biobased and Circular Technologies to ask for tailor made selections, fully conducted to your wishes at a reasonable fee. Contact us at for information or with suggestions for improvement.

If you use data from the Phyllis database we kindly ask you to refer to:

Development of Phyllis2 was co-funded by the EU 7th Framework Programme through the BRISK project, and is being funded by the H2020 Programme (Grant Agreement Number 731101) through the BRISK-2 project.
