Dairy wastewater is enriched in organic matter (about 45-72 g/l, COD) and also contains biodegradable carbohydrates. A three-stage system, NRBC was fabricated as a bench scale unit for lab experiments, to remove organic carbon from the whey. The fabricated NRBC had several advantages, such as quick start-up, high biomass concentration and was additionally able to handle high organic loading rat...

the use of aqueous mixed micellar system consisting of sodium dodecyl sulfate (sds) and polyoxyethylene (23) dodecanol (brij-35) as the mobile phase in reversed-phase liquid chromatography was studied. a group of chlorophenols was used as the test mixture. adding organic modifier to the system showed that the use of low concentrations of organic additives improves efficiency in sds/brij-35 mixe...

Cropping systems like organic farming, selling products at a higher price and promoting environmental sustainability by reducing fertilizer and pesticides, can be more profitable than conventional systems. An economic evaluation of three cropping systems in a seven year period experiment was performed, using a common rotation (fallow-barley-vetch-durum wheat) in a semi-arid rainfed field of Spa...

In the frame of a long-term experiment carried out in Central Italy, conventional and organic winter wheat cropping systems were compared in 2004 and 2005 to evaluate the effect of system management on wheat grain yield and quality. The organic system showed grain and straw yield about 50% lower than the conventional system. Organic grain samples resulted 20% lower in protein content and exhibi...

Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be...
