This project supports a cooperative research effort by Foster Agbelvor of Utah State University and Waleed El-Zawawy of the National Research Center, Cairo, Egypt. The goal of their project is to develop new catalysts that can be used to convert waste agricultural biomass feedstocks directly into phenols and anhydrosugars which can then be used, without any secondary separation steps, to produce biodegradable plastics and other value added products. This research seeks to improve the process of catalytic pyrolysis, which uses heat and a catalyst to break down tough, lignocellulosic biomass, in this case agricultural waste from rice, cotton and banana farming, into small molecules that can be used for other purposes. In this research effort, the products of catalytic pyrolysis, anhydrosugars and phenolics, will be used to make biodegradable plastics. Overall, this process allows plastics to be made from a renewable resource that is otherwise a waste material, while also making a product plastic that causes less pollution. The Egyptian team will be primarily responsible for developing new catalysts while the U.S. team will work to improve the pyrolysis process including the use and recycling of gases, with both teams seeking to improve yields of the desired aromatic products. The research effort will also use the oils produced from fractional catalytic pyrolysis to produce biobased polyurethane foam and "novolac" polymers.Overall this research may lead to new knowledge of how to produce chemicals from lignocellulosic biomass. It will also demonstrate how to generate new and high-value plastic products from agricultural wastes that are widely available in Egypt and the USA, while simultaneously addressing the problem of disposal of those agricultural wastes. In Egypt the byproducts of rice and cotton production are often burned in the fields, increasing air pollution that is responsible for significant deterioration of archeological monuments. The conversion of the agricultural residues to biobased materials has the potential to start new industries and create employment opportunities in rural Egypt and the USA. The project will also involve the participation of female scientists such as Dr. Maha Ibrahim, the training of Egyptian junior researchers and a U.S. graduate student. This project is funded through the US-Egypt Joint Science and Technology Fund Program. Support for the U.S. side of these cooperative projects is provided to the National Science Foundation by the U.S. Department of State. The Egyptian Government provides support for the Egyptian side of the collaboration.

该项目支持犹他州立大学的Foster Agbelvor和埃及国家研究中心的Waleed El-Zawawy进行的合作研究工作。他们的项目的目的是开发新的催化剂，这些催化剂可用于将废物农业生物量原料直接转换为苯酚和甲醇，然后可以在不采用任何次要分离步骤的情况下使用，以生成可生物降解的塑料和其他增值产品。这项研究旨在改善催化热解的过程，该过程使用热量和催化剂分解坚硬的木质纤维素生物量，在这种情况下，在这种情况下，从大米，棉花和香蕉种植中的农业废物变成了可用于其他目的的小分子。在这项研究工作中，将使用催化热解，赤霉素和酚类的产物来制造可生物降解的塑料。总体而言，此过程允许塑料由可再生资源制成，该资源否则是一种废料，同时也制造出塑料塑料，从而减少污染。 埃及团队将主要负责开发新的催化剂，而美国团队将努力改善热解过程，包括使用和回收气体，两支团队都在寻求提高所需芳香产品的产量。研究工作还将使用分数催化热解产生的油来产生生物基聚氨酯泡沫和“ novolac”聚合物。此外，这项研究可能会导致有关如何从木质纤维素生物量产生化学物质的新知识。它还将演示如何从埃及和美国广泛使用的农业废物中生成新的和高价值的塑料产品，同时解决了这些农业废物的处置问题。在埃及，大米和棉花生产的副产品经常在田间燃烧，增加了空气污染，导致考古古迹的严重恶化。将农业残留物转换为生物材料的材料有可能在埃及和美国创造新行业并创造就业机会。该项目还将涉及女科学家，例如Maha Ibrahim博士，埃及初级研究人员和美国研究生的培训。该项目是通过美国埃及联合科学技术基金计划资助的。美国国务院向美国国家科学基金会提供了对这些合作项目的支持。埃及政府为合作的埃及方面提供了支持。
