The standards for effluents discharge are very strict in the Netherlands. The treatment processes have to be very efficient to reduce the quantity of chemical present in the manure (for the BOD from 30 000mg/l to 20 mg/l, Ntotal from 9000 mg/l to 10, Ptotal from 2000 mg/l to 1 and Cl- from 2000 mg/l to 200) and also control the emissions of gaseous material to the atmosphere. Those standards results in high investments in adequate technology for the treatment. Investment cost for granulated fertilizer plant with an annual capacity of 500 000m3 is about 50 millions ECU with gross operational costs of about 25 ECU/m3 (17.95 CAN$) which correspond to about 10 ECU/pig (7.18 CAN$) (considering that one pig produce 0,4m3 of slurry (11% DM). (1 ECU = 0.7177 CAN$ (01/18/98).
