Ambitious targets for renewable power production have been Belstaff Femme Cuir defined for the electric power systems in Europe. The accomplishment of these targets requires the increase in renewable energy production, namely from wind power generation. However, the intermittent nature of wind creates several problems to the power system operation and new approaches based on the combined use of wind power and energy storage technologies need to be developed. In this paper, the concept of the combined use of wind power production and hydro storage/production is exploited, through the development of an operational optimisation approach applied to a wind generator park with little water storage ability. The optimisation model defines the operational strategy to be Boutique Belstaff Belgique followed for the hours ahead by a pump station and an hydraulic generator embedded in a wind/hydro pumping facility, using Belstaff Classic Tourist Trophy Beige the Portuguese energy remuneration rules. The proposed methodology leads to considerable yearly profits for the wind generator production.
The authors in this paper makes an attempt to propose a novel integrated model for the recovery of precious metals (gold - Au and silver - Ag) for the management of e-waste using a combination of hydrometallurgical (chemical) and biometallurgical (low cost biomass) processes. Chemical process involves leaching of gold/silver from electronic scrap using cyanide. The leachate containing gold/silver complex thus obtained is then subjected to biosorption process using low-cost biomass. The model proposed by us will help to strengthen the ‘processing’ part of the functional elements employed for proficient e-waste management. Feasibility study was also conducted to explore the possibility of removal/recovery of silver-cyanide using low-cost biosorbents. Results showed that Eicchornia root biomass and Waste tea powder were efficient biosorbents for leached silver-cyanide from electronic scrap. The concentrated silver-cyanide recovered could further be used as an input material for electroplating industry.
