4.1.8: Presentation and further justification
of the preferred livestock manure treatment
technologies
The recommended livestock manure treatment technologies
in relation to the objectives of the project
are the following:
• Separation technologies (ref. group no. 10) – the
concrete principle is chosen according local prices
and circumstances, both with respect to the type
of mechanical separation technology, and whether
it would be cost-efficient to enhance the separation
with flocculation and/or flotation. The separation
technologies are justified through their
ability to provide the basis for an easy and cheap
removal of excess P to areas with less intensive
livestock productions, where the P can be used in
an environmentally safe way, for instance as
fertiliser for crops. Separation in a P rich fibre
fraction and an N rich liquid fraction is a precondition
for fertilising crops in a balanced way
at farms with high livestock densities (Scenarios II
to V). Mechanical separation can both be a
pre-treatment and a post treatment. The technology
should be a BAT for installations for the
intensive rearing of pigs which have more P in
