In this study, waste olive cake (OC) was utilized as the raw material for the production of biosorbents by chemical treatment and its adsorption capacity for zinc ion was evaluated. Tests were conducted with the total biomass (T) and with the fraction > 2.00 mm (P), in order to determinate the influence of this fractionation step on subsequent treatments. Two chemical agents were used: sulfuric...

the present work was carried out to evaluate the removal of p-nitrophenol by adsorption onto olive cake based activated carbon having a bet surface area of 672 m²/g. the batch adsorption experimental results indicated that the equilibrium time for nitrophenol adsorption by olive cake-based activated carbon was 120min. the adsorption data was modeled by equilibrium and kinetic models. the pseudo...

Olive mill wastewaters and olive cake are effluents generated during oil production process. They represent a major disposal potentially severe pollution problem for the industry, also promising source of substances high value. The aim this study is valorization wastes (OMWW, cake, twigs leaves) to produce enzymes with industrial biotechnological potential, by solid-state fermentation technique ...

In this work, the potential for energy production in Jordan was explored using four distinct types of biomass samples (olive cakes, woods). The proximate analysis, oil content, and higher heating value were all determined experimentally compared to other previously published literature. findings appear be similar materials utilized as solid biofuel feed-stock materials. Olive cake wood have low...

While in the last few years the use of olive cake and mill wastewater as natural sources of phenolic compounds has been widely considered and several studies have focused on the development of new extraction methods and on the production of functional foods enriched with natural antioxidants, no data has been available on the production of a phenol-enriched refined olive oil with its own phenol...

The chemical composition, degradability coefficients (in situ) and ruminal-intestinal disappearance(mobile bag procedure) of dry matter (DM) and crude protein (CP) were evaluated for olive cake (OC)silages treated (DM basis) with additives as follows: (1) untreated OC, (2) OC + 0.5% urea, (3) OC + 0.4%formic acid, (4) OC + 8% molasses, (5) OC + 0.5% urea + 8% molasses, (6) OC + 0.5% urea + 0.4%...
