• Sommario/riassunto: Wastes, whether they are solid wastes or wastewater, are resources from which economic values may be derived. Almost all components of agricultural and food wastewater can be and should be utilized or recovered; the stumbling block of achieving this aspiration is economical, not technical. The last one and a half decades have seen the surging of agricultural and non-agricultural commodity prices across the board and increased public consciousness of environmental impact of industrial wastewater discharge and treatment. The confluence of these new developments have generated new interests an
