US-Egypt Cooperative Research: Alternative Cap and Liner Systems for Municipal Solid Waste Landfills

0310199 Ashmawy描述：该奖项是为了支持佛罗里达坦帕市南佛罗里达大学土木与环境工程系Alaa Ashmawy博士和Ahmed H. Abdel-Rahman，埃及开罗国家研究中心。 城市固体废物（MSW）填埋场的适当设计和建设对埃及社区和美国社区都是一项挑战，埃及社区每年产生超过1000万吨MSW，美国社区每年产生超过2亿吨。 在埃及，压实粘土衬垫或土工合成粘土衬垫是填埋场衬垫和覆盖系统中水力屏障的主要组成部分。 然而，在这两个国家寻找替代的覆盖和衬里系统是出于对经济解决方案的需求，同时保持相同的环境和安全标准。 研究人员计划设计和评估两种替代系统的性能，即分层焚烧炉灰-土壤复合材料和处理过的建筑和拆除碎片。 这些系统将通过广泛的实验室和现场测试计划，在性能有效性和经济效益方面与传统衬管进行比较。 该项目以这两个调查人员在这一领域的专门知识和目前的研究为基础，预计将提供经济和安全的设计，供这两个国家的私营部门垃圾填埋场经营者和市政当局使用。 适用范围：确定和评价替代性填埋场衬垫和覆盖系统是一个对地质环境界具有重大意义的及时问题。 这项研究将引入创新的方法，在衬里和覆盖系统中有益地利用焚烧炉灰和建筑垃圾。 成功完成该项目所需的设施在USF和NRC都有。 该项目以这两个调查人员在这一领域的专门知识和目前的研究为基础，预计将提供经济和安全的设计，供这两个国家的私营部门垃圾填埋场经营者和市政当局使用。 项目活动包括通过南佛罗里达大学工程学院的REU方案，让一名研究生和来自代表性不足群体的本科生参加。 国际研究机会提供给美国研究生谁将访问埃及实验室。 研究结果将通过在期刊、会议记录和互联网上发表来传播。该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。

Abdel-Rahman, National Research Center, Cairo, Egypt. Proper design and construction of municipal solid waste (MSW) landfills is a challenge to Egyptian communities where more than 10 million tons of MSW are generated annually, and to U.S. communities where over 200 million tons are generated annually. In Egypt, compacted clay liners (CCLs) or geosynthetic clay liners (GCLs) form the main component of the hydraulic barrier in the landfill liner and cover system. However, the search for alternative cover and liner systems in both countries is driven by the need for economical solutions while maintaining the same environmental and safety standards. The investigators plan to design and assess the performance of two alternative systems, namely layered incinerator ash-soil composites and processed construction and demolition debris. These systems will be compared to conventional liners in terms of their performance effectiveness as well as economical benefits through an extensive laboratory and field-testing program. The project builds upon the expertise and current research of both investigators in this field, and is expected to provide economical and safe designs for use by private sector landfill operators and municipal authorities in both countries. Scope: Identification and evaluation of alternative landfill liner and cover systems is a timely issue of significant importance to the geoenvironmental community. The research will introduce innovative methods for beneficial use of incinerator ash and construction debris in liner and cover systems. The facilities needed for successful completion of the project are available at both the USF and the NRC. The project builds upon the expertise and current research of both investigators in this field, and is expected to provide economical and safe designs for use by private sector landfill operators and municipal authorities in both countries. The project activities include the participation of a graduate student as well as undergraduate students from underrepresented groups, through an REU program at the University of South Florida's College of Engineering. International research opportunities are provided to the U.S. graduate student who will visit the Egyptian laboratories. Research findings will be disseminated through publication in journals, conference proceedings, and the Internet. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
