This study aims to identify ways that efficiently reduce the energy consumption of the industrial sector. We use the logarithmic mean divisia index method to measure the impact of the various driving forces of energy consumption during the period 2010-2014. We then apply the index decoupling to analyze the correlation between energy consumption and industrial growth. The findings indicate that industrial growth is a major driver of energy consumption, while reductions in energy intensity and industrial structure play an important role in limiting energy consumption. In addition, energy consumption and energy intensity follow different patterns in each sub-sector; we therefore conclude that the application of different sub-sector policies is preferred over global policies. Globally, decoupling has not been identified during the period 2010-2014, however, decoupling occurs for more detailed year periods.
Coffee husk was used as potential biosorbent in order to adsorb volatile compounds from wastewater of clove oil distillation and the oil was recovered from the wastewater. Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used for the characterization of coffee husk. Coffee husk was carbonized and activated using hydrochloric acid. Identification of functional group by infrared spectrum on coffee husk showed the dominant peaks at 3327 cm −1 (O−H) and 1608 cm −1 (C− −C, C− −O). The activated carbonized coffee husk showed the OH-peaks weakly in the spectrum. SEM surface analysis showed an uneven surface on the coffee husk. The optimum adsorption of clove oil was determined by chemical oxygen demand (COD). Optimization of coffee husk adsorbent was obtained by waste volume of 10 ml, the weight of 1.5 g and contact time of 120 min. The adsorption efficiency of the organic compound from wastewater was 37.96%. Eugenol and eugenol acetate recovery of coffee husk adsorption were 79.44% and 54.05%, respectively. The recovery of clove oil in wastewater distillation was 0.31%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
