The resulting sediment could be used for production of mineralorganic
fertilizer. The filtrate was recycled to prepare the lime milk
solution, and eventually, to dilute the raw pig manure. The final
filtrate could be used to irrigate crops or it could be treated in
conventional biological wastewater treatment plants. The emitted
vapors did not contain odors (Makara et al., 2015, Sowka et al.,
2013).
