Life Cycle Assessment


According to the European Commission, 70% of proteins needed for animal feed in Europe are imported. This figure has been stable over the past 40 years and signals a persistent and current European protein deficit.
In addition, today main proteins sources (fishmeal and soybean) to formulate fish feed present either economic or environmental burdens:

  • Fishmeal production has been stable for more than 40 years while aquaculture market grows year over year, creating pressure on fish meal prices.
  • Soybean production is a contributor to deforestation in production areas and can only be used in limited amounts in fish feed due to anti-nutritional factors.

70% of proteins needed for animal feed in Europe are imported

In this way there is a real need of proposing disruptive and more sustainable animal feed and protein solutions to the fish feed market to address the protein gap and secure aquaculture growth.
The opportunity exploited in SYLFEED is to look at a more sustainable raw material source to produce protein for feed: Lignocellulose (non-food biomass from wood).


Concept & Approach

  • Demonstrate the upscale of Arbiom’s technology converting wood residues into protein-rich feed ingredient at demonstration level in order to prepare for industrial scale-up.Demonstrate Single Cell Protein (SCP) production at large scale, with a production stream reaching ~1 kT per year
  • Formulate protein-rich fish feed incorporating SCP and validate its nutritional properties in vivo.
  • Demonstrate commercial viability of the product: market potential, price level, offer and demand
  • Demonstrate environmental benefit of SCP protein ingredient compared to other protein sources by measuring impact through a complete life cycle analysis (LCA)
  • Maximising the contribution of the project results to sustainable economic and job growth: increasing revenues of biomass producers through diversification of their activities as well as securing jobs in pulp and paper industry.

SYLFEED demonstrates a novel concept of a new value chain from biomass sourcing to fish feed manufacturing.

This new value chain starts with the collection of wood residues. Collected biomass is then converted to sugars and lignin through Arbiom’s fractionation technology. This step allows the recovery of high quality sugars suitable for bioconversion and fermentation.

Sugars are then converted through fermentation into protein-rich ingredient suitable for fish feed formulation.

The project covers the whole value chain.
