Technoeconomic analysis and environmental sustainability estimation of bioalcohol production from barley straw

چکیده
European Union bioeconomy policy emphasizes that the production of renewable transportation fuels should replace fossil as much possible. In particular, utilization waste or side-stream lignocellulosic materials for fuel is highly recommended. Moreover, future crises forcing a reliance on locally available sources and energy may become increasingly common. Barley straw, common agricultural residue in northern Europe, potential raw material bioalcohol via fermentation. this study, technoeconomic environmental sustainability bioethanol biobutanol from barley straw were evaluated. When compared with gasoline use, greenhouse gas emissions reduction 77.6% 72.1% achieved ethanol butanol production, respectively. Thus, emission 65% biofuels demanded by directive was both biofuel processes However, our results indicated well-known mature technology, an economically feasible process (NPV positive, IRR 20%) but Clostridium species through acetone-butanol-ethanol fermentation has still challenges to overcome negative, below 10%). This mainly due low yield high recovery costs butanol.

Application of barley straw to remove nitrate from drainage water
ABSTRACT-Nowadays farmers often use N-fertilizers to increase crop yield, but they lost quickly by leaching causes environmental contaminations that reported as most important source of pollutant. Although biofilters are useful for removing nitrate from drainage water, but many researches show that they need an external carbon source to sustain denitrification. Many researchers study on differe...

15 صفحه اولEnvironmental impacts and sustainability of egg production systems.
As part of a systemic assessment toward social sustainability of egg production, we have reviewed current knowledge about the environmental impacts of egg production systems and identified topics requiring further research. Currently, we know that 1) high-rise cage houses generally have poorer air quality and emit more ammonia than manure belt (MB) cage houses; 2) manure removal frequency in MB...
