AbstractThe proposal is for a two-day workshop that will focus on the development of mathematical models for sustainable landfilling. This workshop will build upon existing expertise in landfill process modeling by organizers from Delaware and Nebraska, and will position researchers in both states to make significant advancements in the development of mathematical models for landfill processes. The workshop theme "Models for Sustainable Landfilling" fits in well with Delaware's EPSCoR Research Infrastructure Improvement (RII) Grant on Complex Environmental Systems, and the new University of Delaware (UD) Center for Critical Zone Research, designed to conduct basic research concerning the Earth's life-sustaining, near-surface environment. The proposed workshop will open up a new focus area within UD's Center for Critical Zone Research. This workshop will also advance two University-wide research initiatives in Water Research and Energy Science at the University of Nebraska-Lincoln (UNL). Information generated from of the proposed workshop is expected to be utilized by members of the UNL Water Center and the Nebraska Center for Energy Science Research, which has a special interest in alternative energy sources. The issues around landfills are significant in the US. About 50% of the solid waste generated in North America is landfilled. The use of landfilling as a final disposal option for solid waste is expected to continue for the foreseeable future: other treatment technologies, e.g., incineration, produce appreciable residues that must be landfilled, and recycling efforts always result in final waste products that must be disposed. As the solid waste industry looks to the future, two key challenges have emerged: efficiently utilizing landfill capacity through operating landfills as controlled bioreactors, and assessing the fate of new chemical compounds and biological agents that are disposed in landfills. The challenges related to efficient landfill operation and the fate of emerging contaminants must be addressed to advance a new paradigm in landfill management sustainable landfilling. To address these challenges and to advance sustainable landfilling, suitable models are needed to describe fluid flow, heat transport, waste biodegradation, and the fate of emerging chemical compounds and biological agents in landfills. While mathematical models for some of these landfill processes have been introduced in the scientific literature, existing models are rudimentary. Intellectual Merit: A major factor limiting the advancement of landfill models is the broad range of disciplines that must be mastered to develop effective models. This workshop will bring together experts from two EPSCoR partner states, institutions from non-EPSCoR states, and several foreign institutions that together represent the intellectual leadership covering the range of relevant processes. This group will assess the current state of the art in landfill modeling, note important scientific gaps hindering model advancement, and recommend a path forward to address these gaps, which will likely include short and long term research questions as well as field monitoring programs to refine and test proposed models. Broader Impacts: Broader impacts include 1) improved understanding of the diversity of questions limiting landfill models, 2) improved understanding by US scientists of landfill modeling research abroad, 3) development of a plan to advance such models, 4) and organization of the scientific community within EPSCoR states to address landfill modeling questions. The workshop will involve graduate students from underrepresented groups. In addition to benefiting the research community, the advancement of landfill modeling is expected to result in improvements in landfill management practices throughout the US.

AbstractThe建议是一个为期两天的研讨会，将重点放在可持续填埋的数学模型的发展。本次研讨会将建立在现有的专业知识，在垃圾填埋过程建模的组织者从特拉华州和内布拉斯加州，并将定位在这两个国家的研究人员，使数学模型的发展垃圾填埋过程的显着进步。研讨会的主题"可持续垃圾填埋模式"与特拉华州的EPSCoR研究基础设施改善（RII）复杂环境系统赠款以及新的特拉华州大学（UD）临界区研究中心非常吻合，该中心旨在进行有关地球生命维持的基础研究，近地表环境。拟议的研讨会将在UD的关键区研究中心内开辟一个新的重点领域。本次研讨会还将推进内布拉斯加大学林肯分校（UNL）水研究和能源科学的两项大学范围内的研究计划。从拟议的研讨会产生的信息预计将被UNL水中心和内布拉斯加州能源科学研究中心的成员，其中有一个在替代能源特别感兴趣。垃圾填埋场的问题在美国很重要。 在北美，大约50%的固体废物被填埋。在可预见的未来，填埋作为固体废物的最终处置办法预计将继续使用：其他处理技术，例如，焚烧产生大量必须填埋的残留物，回收利用的努力总是产生必须处理的最终废物。随着固体废物行业展望未来，出现了两个关键挑战：通过将垃圾填埋场作为受控生物反应器进行操作来有效利用垃圾填埋场容量，以及评估在垃圾填埋场处置的新化合物和生物制剂的命运。必须解决与有效的填埋作业和新出现的污染物的命运有关的挑战，以推进填埋管理的新模式。为了应对这些挑战并推进可持续的垃圾填埋，需要合适的模型来描述流体流动，热传输，废物生物降解以及垃圾填埋场中新兴化合物和生物制剂的命运。虽然科学文献中已经介绍了其中一些填埋过程的数学模型，但现有的模型是初步的。智力优势：限制填埋场模型进步的一个主要因素是必须掌握开发有效模型的广泛学科。本次研讨会将汇集来自两个EPSCoR伙伴国的专家、非EPSCoR国家的机构以及几个外国机构，他们共同代表了涵盖一系列相关流程的知识领导力。该小组将评估垃圾填埋场建模的最新技术水平，指出阻碍模型进步的重要科学差距，并建议解决这些差距的途径，其中可能包括短期和长期的研究问题以及现场监测计划，以完善和测试拟议的模型。更广泛的影响：更广泛的影响包括：1）提高对限制填埋场模型的问题多样性的理解，2）提高美国科学家对国外填埋场建模研究的理解，3）制定推进此类模型的计划，4）组织EPSCoR州内的科学界解决填埋场建模问题。该讲习班将有来自代表性不足群体的研究生参加。除了有利于研究界，垃圾填埋场建模的进步预计将导致在整个美国垃圾填埋场管理实践的改进。
