Protein feed from grass silage by biotechnical means

Project status

Project started in February 2013.

Project ended in March 2014.
(Continuation of the project is under discussions.)

The project is led by Valio and combines the expertise of five research institutes: Aalto University, MTT, VTT, Metla and University of Oulu. Person in charge of the project is Matti Harju, Valio.


Project description

The objective of the project is to pre-study the technical and economical feasibility of the production of protein feed from grass silage. Grass and especially grass silage (grass feed) composes an exciting alternative to wood-based raw material for biotechnical utilization.

In this pre-study the technical and economical feasibility of the production of domestic protein feed from grass silage will be studied. The feasibility of transforming grass silage into sugar and the most optimal fermentation host and process will be analysed.
