Biomass from energy crops and agroindustrial wastes can be biologically converted to liquid or gaseous fuels, such as ethanol, methanol, methane and hydrogen, which was recently characterized as the fuel of the future. Hydrogen is a clean and environmentally friendly fuel, which produces water instead of greenhouse gases when combusted. It can be produced by renewable raw materials, such as org...

Extended Abstract Nanoscale zero-valent iron (nZVI) particles have demonstrated to effectively remove a wide range of pollutants from water, such as chlorinated compounds, heavy metals and dyes. However, the use of nZVI in environmental remediation is limited do to its lack of stability and easy aggregation [1]. nZVI can also deliver the contaminants that had already been adsorbed in their surf...

The performance of olive stone activated carbon (OSAC) for sorption of Cu2+, Zn2+ and Ni2+ ions was investigated via batch technique. OSAC materials were prepared under different physially activation conditions. Olive stone waste was physically activated with N2 gas and steam gas at 900oC at 3.5h hold time (OSAC-3) was choice as the best one for Cu2+, Zn2+ and Ni2+ removal. Characterization for...

The valorization of food processing by-products, wastes and effluents is a challenging opportunity for the sustainable and competitive development of several relevant industrial sectors. One of the best examples of a biorefinery applied to plant processing wastes is that of the olive oil sector by-products including leaves and olive mill wastewaters (OMW). Management of OMW, in particular, has ...

Abstract An attempt to shed light on the use of agro-industrial-based wastes as supplementary cementitious material (SCM) or alkali-activated binder (AAB) is mainly focused in this review paper. The SCM AAB acts a suitable replacement for cement, cement manufacturing tends contribute 8–10% global CO 2 emissions. To gain acceptability construction industry, diverse must demonstrate their potenti...

chlorination of natural water containing humic compounds, produce significant amount of disinfectant by - products. the most important of such compounds are thlvis and halo acetic acids, suspected to cause cancer in animals and human. studies showed that under usual processes of water treatment plants, thms can not be removed effectively. since chlorination is the final process of treatment, it...
