Ammoxidised carbons were produced from three different starting materials: an activated carbon obtained from wood by chemical activation using the phosphoric acid process, a steam activated peat-based carbon, and a char obtained from a low-cost biomass feedstock, olive stones. Nitrogen was successfully incorporated into the carbon matrix of the different materials, the amount of nitrogen uptake...

Introduction The production of scrap tires only in the EU, USA and Japan is around 6 million tones per year. As the associated automotive industries grow the huge quantity of waste tires presently produced in the world will certainly increase in the future [1]. Thus the disposal of scrap tires becomes a serious environmental problem. The production of activated carbons from solid wastes is one ...

semi-aerobic leachate is characterized by organic matter (cod, bod) which is relatively low in concentration and difficult to biodegrade. in conventional treatment systems, the low biodegradability is attributed to partial stabilization of leachate at the landfill. biological treatment of leachate in malaysia is not well established and any important data for the treatment process is not availa...

Olive oil production sector plays an Portuguese economy. It had a major growth ove increasing its weight in the overall national exp market penetration for Mediterranean traditio increasingly more demanding, especially in the N markets, where consumers are looking for more su Trying to support this growing demand this study production under the environmental and eco-effici The analysis consider...

Lactic acid can be produced by fermentation of organic matters present in various wastes with the addition of various carbon and nitrogen sources using Lactobacillus species. Organic wastes form kitchen garbage and foodprocessing industries are especially rich in carbon and moisture content. The present study investigates the treatment of the organic wastes using microbiological process for eff...

Biomass wastes are considered as cost-effective and sustainable precursors to prepare activated carbons for CO2 capture. In this study, two biomass-derived activated carbons were prepared using peanut shell and sunflower seed shell, and the optimal activated carbons were obtained at low KOH/carbon ratio of about 1. The peanut shell derived activated carbon (P-973-1.00) and sunflower seed shell ...

In the present work, a method for extracting cellulose from olive industry solid waste has been developed. The method involves subjecting solid olive waste to kraft pulping, followed by multistep bleaching processes. The totally free chlorine chemical bleaching sequence APEP was the most effective and gave an average cellulose yield of about 35%. The extracted cellulose was extensively characte...

In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...
