“…Some treatment processes could not be implemented on a large scale because of high costs (Sbai et al, 2000). Interest is focused on biological treatment using aerobic bacteria and fungi (Chatjipavlidis et al, 1996;Sbai et al, 2000) for bioremediation of olive mill wastewater by composting (Papafotiou et al, 2004).…”

Olive mill waste management has been a major issue of environmental concern for all olive oil-producing countries. Several soil amendments have been used to improve the physical and chemical characteristics of rootzone profiles and mixes. Olive mill waste (OW, olive stone and pulp) in different ratios (10%, 30%, or 50% v/v) was investigated for use in production of lettuce (Lactuca sativa L., cvs. Paris Island and Corsica) and chicory (Cichorium intybus L., cv. Chicory white stem) seedlings by replacing part of the peat or perlite in the growing medium. Also evaluated was use of OW (10% or 30% v/v) in soil for production of lettuce (cv. Paris Island). The OW extracts at 10 −1 to 10 −6 accelerated seedling germination and radicle length. Under nursery conditions, the addition of OW as substrate component improved seed emergence for chicory and lettuce (cv. Corsica) but suppressed lettuce cv. Paris Island seed emergence but not mean emergence time. Olive mill waste combined with perlite in different ratios performed better regarding seed emergence compared with mixtures of OW and peat. Addition of OW in perlite and/or peat reduced leaf fresh weight and leaf numbers. Plant height decreased only in substrates where perlite was mixed with OW. Under greenhouse conditions, increased OW content in soil reduced (up to 25%) lettuce plant fresh weight compared to the control. This effect was mainly due to shorter leaves rather the number of leaves produced. Reduced plant growth occurred with reduced root fresh weight; root length was not affected by treatment. Use of soil:OW at 90:10 v/v mix can be applied to lettuce in the greenhouse; diluted OW extract and OW (at 10%-30%) may be used for seed priming and seedling production, respectively, and may increase profit.

“…Nevertheless, several methods have been proposed for treating OMW, such as composting (Chatjipavlidis et al, 1996), evaporation ponds (Mountadar et al, 1997), thermal treatment (Baccioni, 1981), physicochemical (Achak et al, 2008), biological treatments (Mantzavinos and Kalogerakis, 2005) and land spreading (Sierra et al, 2001;Mechri et al, 2007;Mechri et al, 2008;Mekki et al, 2007;Saadi et al, 2007). But few works directed the attention to the treatment by infiltration-percolation which was often applied to urban wastewater and studied by several authors (Brissaud and Lesavre, 1993).…”

“…In the Aegean Region of Turkey, agro-industrial wastes produced annually are 22,210 tonnes of "soapstock" from plant oil, 416,319 tonnes of "black water" and 475,794 tonnes of "prina" from olive oil, 75,600 tonnes of "cheese water" from milk production, and 19,422 tonnes of "blood" from meat production (Arslan 1997). Chatjipavlidisa et al (1996) described a method to process liquid wastes from the olive oil industry so that they could be used as a biofertilizer for potato growth. Pala et al (2001) noted that liquid and solid wastes from the olive oil industry could be used as organic fertilizer or compost.…”

In this study, the effects of various agro-industrial wastes were investigated when applied to soil alone or in combination with chemical fertilizers, regarding the risks of boron and heavy metal pollution of soils and plants. Nine combinations of production residues from various agro-industries, urban wastes, and mineral fertilizers were applied to potatoes in a field experiment. The content of available boron in the soil differed significantly (p < 0.05) among the applications. Generally, B values were found to be slightly higher when soapstock, prina, and blood were used alone or in combination. Although total Co, Cd, and Pb contents of soils showed no significant differences between the applications, Cr content differed significantly (p < 0.05). No pollution risk was observed in soil in respect to total Co, Cd, Pb, and Cr contents. The amount of boron and heavy metals in leaves showed no significant differences among the applications. Cobalt, Cd, and Pb in leaves were at normal levels whereas Cr was slightly above normal but well under the critical level. Boron was low in tubers and varied significantly between applications such as Co and Cd. The Co content of tubers was high, Cd and Cr contents were below average, and Pb content was between the given values. Some significant correlations were found between soil characteristics and the boron and heavy metal content of soil, leaves, and tubers.
