4: RESULT OF DATA ANALYSIS
338 page long document, describing several aspects
of pollution from pig and poultry farming. Energy
issues and emissions to the atmosphere are in focus of
the document. The lower focus on manure treatment
reflects the development in industrial pig farming
since the document was adopted. At that time, the
average Danish pig farm for example, had 550 pigs
(including piglets, sows and production pigs) while
the average herd size is 2.250 pigs today. The need
to treat/process manure has vastly increased, and
will most probably continue to increase as national
economies in the new EU Member States increases.
Livestock manure treatment technologies have
impacts on the leaching of N and P, and they need
to be considered within the BREF.
Criteria for what is to be considered as a BAT
for manure treatment in intensive rearing of poultry
and pigs are not specified within the legislation or
in the BREF.
A review process of the current BREF for intensive
rearing of poultry and pigs was initiated in June
2008. The Technical Working Group members are
asked to communicate recommended best available
techniques to the IPPC Bureau by February 2010.
The official guiding documents for the revision process
of the BREF on the IPPC webpage (http://eippcb.jrc.ec.europa.eu/index.html),
do not so far give
special attention to leaching of nutrients to water.
Several respondents have shown interest in the
“Best Practice Manure” project objectives and activities,
especially the list of cost effective technologies to
reduce leaching of nutrients from pig manure. There
seems to be a window of opportunity to develop a
BREF who gives better attention to leaching of nutrients
to water, and promote cost efficient manure
treatment technologies that reduce this problem. It
is important to take this opportunity, as it will take
several years before the next review.
