SynopsisThe cellulosic wastes, bagasse and sawdust, were treated with different acidified solvents; chloroform, dioxan, ethanol, ethylacetate, dimethyl sulfoxide and dimethyl formamide; for increasing periods up to 36 h. The treated materials were delignified, dried and introduced in the fermentation media as inducing carbon source for Rchoderma reesei. The untreated materials and pure cellulose powder were used individually in control and reference media, respectively. The fermentation media containing bagasse treated for 8 h in chloroform or dioxan gave a promising cellulase activity, nearly the same as that from the reference medium. The untreated bagasse gave a markedly low cellulase activity.The media with treated sawdust gave a relatively higher enzyme activity but far below the reference medium. The sawdust treatment with the solvents mentioned resulted in a very mild effect because of its high content of admixtures, lighin and hemicellulose bonding cellulose.

In this work, 13 different solutions for the optimization of energy consumption of a building located in the tropical city of Bandar Abbas are studied out via the EnergyPlus and TRNSYS (Transient System Simulation Tool) commercial codes. Then, the suggested solutions are economically studied and the most economically viable ones are proposed. Ultimately, an energy efficient consumption scheme is put forward with the approach of solar energy utilization. Results reveal that 9 out of 13 studied solutions are techno-economically viable; and by implementing these solutions the energy consumption of the building could be decreased by 81% up to 165624.1 kWh as well as preventing 63022.66 kg of CO2 emission.
