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 和埃及开罗国家研究中心的 Waleed El-Zawawy 的合作研究工作。他们项目的目标是开发新的催化剂，可用于将废弃的农业生物质原料直接转化为酚和脱水糖，然后无需任何二次分离步骤即可用于生产可生物降解的塑料和其他增值产品。这项研究旨在改进催化热解过程，该过程使用热量和催化剂将坚硬的木质纤维素生物质（在本例中是来自水稻、棉花和香蕉种植的农业废物）分解成可用于其他目的的小分子。在这项研究工作中，催化热解的产物、脱水糖和酚类物质将用于制造可生物降解的塑料。总体而言，该工艺允许用可再生资源制造塑料，而塑料产品本来就是废料，同时还生产出污染更少的塑料产品。 埃及团队将主要负责开发新催化剂，而美国团队将致力于改进热解工艺，包括气体的使用和回收，两个团队都致力于提高所需芳烃产品的产量。该研究工作还将利用分级催化热解产生的油来生产生物基聚氨酯泡沫和“酚醛清漆”聚合物。总的来说，这项研究可能会带来如何从木质纤维素生物质生产化学品的新知识。它还将展示如何利用埃及和美国广泛使用的农业废物生产新的高价值塑料产品，同时解决这些农业废物的处置问题。在埃及，稻米和棉花生产的副产品经常在田里焚烧，增加了空气污染，导致考古遗迹严重恶化。将农业残留物转化为生物基材料有可能在埃及农村和美国开创新产业并创造就业机会。该项目还将包括玛哈·易卜拉欣博士等女科学家的参与，以及对埃及初级研究人员和一名美国研究生的培训。该项目由美国-埃及联合科学技术基金计划资助。美国国务院向美国国家科学基金会提供对这些合作项目美方的支持。埃及政府为埃方合作提供支持。
