What will be done during the project?

As a result of the project, new raw material flows to produce biochar will be found, the processing degree of the biochar will be increased, new applications will be found, and a market will be created for biochar products.

Biochar is more about a product group than an individual product, because the properties of biochar are influenced by, among other things, the raw material used, its pre-treatment, pyrolysis processing parameters and post-treatment. For this reason, the production of optimal biochar is a complex process, where several factors need to be addressed. The potential uses of biochar are also versatile, because the properties can be modified according to the needs set by applications. During the project, following applications are considered:

• Air filtering/cleaning
• Acoustics
• Circular economy based fertilizers and substrates
• Replacing fossil fuels

Different raw materials, such as willow, different wood based side streams and wastes originated in different industries, and plastic waste originated in agriculture and farming, are studied to define the suitable pyrolysis processing parameters to reach the required quality for each application. Different pre-treatment methods of materials will be also tested and developed. During the project, guidelines for quality verification of the biochar production including required quality characteristics and recommended analysis and testing methods to be used.
