Ref No. 59 Algae production on liquid manure substrates
Brief description Description of the effect on leaching (positive or negative) of N and P
Pilot research has started in for instance Holland on the feasibility of algae production on
liquid manure substrates. The challenging idea behind this is to utilise the facts that algae
grows well in waters that are rich on plant nutrients, that algae in pilot studies has shown
incredible high productivity levels, and that they are relatively easy to recover bioenergy
sources from, in the form of plant oil that can replace fossil fuels. Plant nutrients can be recirculated
in the agricultural production, the P being of very high quality that could be used
as feed ingredient.
The expected effect is similar to that of the separation technologies
described above: The rest-fibre fraction would be possible to export to
areas with low livestock density.
The production would result in three components: Plant oil, a rest-fibre fraction and reject
water, which dependent on local price conditions can be cleaned up to the economic optimal
level.
