Nowadays, manure treatment demand is increasing due to N
\nsurplus in most of the European areas. De-localization of piggery farms to less concentrated areas, for full fertilizing nutrient recovering
\nby land spreading, is very difficult for several reasons: the
\npresence in the same areas of traditional crops and typical productions,
\nlike in Italy the parmesan cheese, and also for other reasons
\nrelated to food quality and safety market strategies. One possible
\nsolution is to export manure nutrients to less concentrated areas.
\nTherefore, technologies for manure valorisation and volume reduction
\nare needed. Solid\/liquid separation of raw manure is a key
\ntechnology, since it can concentrate a high quantity of nutrients
\nin a small volume, making transportation off-farm easier and
\ncheaper. The remaining liquid fraction could be used on-farm as
\nfertilizer. Rather often, especially for large, intensive swine farms,
\nN surplus still remains after soli\/liquid separation, therefore many
\nfarmers will benefit with further treatment to reduce nitrogen
\nload. C\/N ratio represents the main treatment bottle neck. Better
\nelectron donors use is needed, therefore solid\u2013liquid separation
\nas pre-treatment allows a more balanced C\/N ratio in liquid fraction.
\nAmong the available biological technologies, SBRs showed
\nthe most promising performances. According to lab-scale as well
\nas full scale results, SBR allows up to 98% removal of COD, N and
\nP, and moreover it\u2019s easy to be managed and controlled. Thus,
\nthe proposed process can represent a new chance for solving environmental
\nproblems generated by large industrial piggeries. Economic
\nevaluations indicated that the operative costs are
\naffordable by most pig farmers, with minor impact on meat price.
\nElectric energy costs, that represent the biggest cost item, can be
\ngreatly reduced if the separated solids are anaerobically digested
\nfor cogeneration. Co-digestion with energy crops and\/or organic
\nwastes can even increase the profitability of the process. For these
\nreasons, in Italy, several integrated anaerobic\/aerobic biological
\ntreatment for intensive swine production are going to be constructed
\nand revamped in the near future.<\/p>\n","protected":false},"excerpt":{"rendered":"
