Abstract Hydrogen could be considered a synthetic secondary power carrier fuel in the years to come, subsequent to the fossil fuels economy. Thus the concept 'hydrogen economy' shall be defined, and it will also have a great influence in the future years.The field of power generation (producing electric power), transports, (electric cars), chemistry (hydrogen is a major raw material) are potential users of hydrogen.The experts support, by means of a series of economical and strategic analysis ma...

Abstract Wind erosion, which strongly affects both plant and soil development in arid environments, is dependent on soil properties, wind characteristics and plant cover. In a semiarid zone in SE Spain, a new technique consisting of dusting plants with a forced wind stream reduces tillage and significantly increases productivity. By using a blower once a year, dust is raised and partly retained by plants, and eventually ends up in the understory. To assess the influence of this technique on ...

Abstract This study was aimed to stimulate laccase production by Trametes pubescens MUT 2400 by using a tomato-based medium. Two sequential 2x2 factorial designs were used to determine the effect of carbon (C) and nitrogen (N) source concentration on laccase activity and biomass concentration; copper was used as the sole inducer (0.75 mM). Analysis of the first factorial design showed that N had a strong positive effect on the maximum laccase activity, which occurred at day 12 of cultivation...

Abstract Heavy metals are considered important pollutants found in sewage sludge. That is why sewage sludge can have a limited use as fertilizer in agriculture. Some aquatic plants can remove nutrients and heavy metals from media as sewage sludge or contaminated sediments. In this paper, we investigated the effects of different concentration levels of two heavy metals (Ni and Cd), respectively, 10, 35, 85 and 20, 50, 150 mg/kg in sedimentary media on plant uptake of Ni and Cd, considering th...

Rapeseed meal (RM) is an abundant and cheap by-product of oil extraction process. RM is a rich source of nitrogen, carbon, and minerals. Thanks to these features, RM has a striking potential for eco-friendly production of high value products in biotechnological processes. In this study, the possibility of using a low-cost medium based on the water soluble fraction of RM for laccase production by the fungus Pleurotus ostreatus has been evaluated and compared with the use of synthetic complex ...

Waste frying oil (WFO) is a complex and heterogeneous waste collected mainly from restaurants and, to a lesser extent, from food processors and households. In the last decades, interest for this waste has deeply grown and a strong competition in grabbing this raw material has begun. About 90% of WFOs collected in Europe is recycled for biodiesel production, being the high free fatty acids (FFAs) concentration in WFOs one of the main drawback limiting the yield of the conversion process. In th...

With population growth and increasing industrialization, enormous amounts of agro-industrial wastes are being produced. Without proper use, these keep piling up leading to tremendous pressure on environmental safety. There is also considerable economic interest not only in the proper utilization of these wastes, but also in developing appropriate processes for this purpose. Sludge generated in pulp and paper mills is one of such solid wastes. Although several studies have investigated its reuse,...
