Bioenergy production involves different agents with potentially different objectives, and an agent’s decision often has transboundary impacts on other agents along the bioenergy value chain. Understanding and estimating the transboundary impacts is essential to portraying the interactions among the different agents and in the search for the optimal configuration of the bioenergy value chain. We develop an agent-based model to mimic the decision making by feedstock producers and feedstock-to-biofuel conversion plant operators and propose multipliers (i.e., ratios of economic values accruing to different segments and associated agents in the value chain) for assessing the transboundary impacts. Our approach is generic and thus applicable to a variety of bioenergy production systems at different sites and geographic scales. We apply it to the case of producing ethanol using corn stover in Iowa, USA. The results from the case study indicate that stover removal rate is site specific and varies considerably with soil type, as well as other factors, such as stover price and harvesting cost. In addition, ethanol production using corn stover in the study region would have strong positive ripple effects, with the values of multipliers varying with greenhouse gas price and national energy security premium. The relatively high multiplier values suggest that a large portion of the value associated with corn stover ethanol production would accrue to the downstream end of the value chain instead of stover producers. 相似文献

利用大流量主动采样器采集了广州市天河区(23°08''56" N,113°21''30" E)和五指山国家自然保护区(18°54''02" N,109°41''24" E)两个典型地区的大气气相和颗粒相样品,测定了8种新型卤代阻燃剂(new halogenated flame retardants,NHFRs)的浓度,包括syn-DP、anti-DP、TBPH、PBEB、HBB、TBE、TBB、DBDPE.结果表明,广州大气中∑NHFRs平均浓度(335 pg·m-3)远高于五指山(90.6 pg·m-3).广州大气中DBDPE为优势单体,占比为66.9%;五指山大气中NHFRs则以TBPH为主(65.8%).季节变化上,广州的∑NHFRs浓度呈现一定季节变化,而五指山的∑NHFRs无明显季节变化,这可能与两地NHFRs的来源不同有关.结合主成分分析、风向频率和后向轨迹模型分析,发现两地阻燃剂来源有较大的差异:广州大气中NHFRs可能主要来源于电子垃圾拆解、工业输入和消费品的再挥发,而五指山大气中阻燃剂可能以外源输入为主.健康风险评价结果显示,我国大型城市大气中高浓度NHFRs的持续暴露会对城市居民健康特别是婴儿健康造成潜在危害. 相似文献

Releasing nitrogen from ammoniated lignin by white rot fungus cometabolizes environmental pollutants
The nitrogen-modified lignocelluloses(NML) produced under oxic ammoniation was metabolized by white rot fungus, NH4^ -N was released, NO3^- -N concentration was decreased and total nitrogen loss was blocked within incubation period. During releasing nitrogen from the metabolism of NML, white rot fungus cometabolized recalcitrant environmental pollutants and showed higher degradation capability. Results indicated that this NML complex colonized by white rot fungus might be effective with economic feasibility when they are applied into the vast field ecosystem, it might stabilize NH4^ nitrngen flux and bioremediate the polluted environmental sites. 相似文献

当主流商学院开始将更多的企业社会责任(CSR)话题带入教室时,一些教育家仍认为这些机构的努力不够。他们相信,现在所需要的,是围绕可持续发展概念来确定MBA教学大纲,大纲仍然讲授基础科目,但要染上绿色。 相似文献
