This Partnership for Innovation Project from the Polytechnic Institute of New York University (NYU-POLY) addresses the need to develop bioplastics that, in addition to being biobased and offering a desirable environmental footprint, will also provide future customers with improved performance characteristics over existing materials. To do so is critical in order to motivate consumers to renounce current petro-derived materials for new-to-the-world bioplastics such as those proposed herein. The strategy pursued by the project team is to utilize bioplastics with the right combination of properties while focusing on engineering the interface or boundaries between these components to optimize material performance. Specifically, selected material components include cellulose nanowhiskers (CNWs), poly (omega-hydroxyfatty acids (P (omega-OHFAs)), and poly (lactic acid) (PLA). While P (omeg-OHFAs) provides good hydrolytic stability and physical toughness, the PLA-CNW nanocomposites provide high modulus and improved use temperatures. The knowledge-enhance partner (KEP) small businesses in this project, PolyNew Inc. (engineered CNWs) and SyntheZyme LLC (P(omega-OHFAs) and their blends with PLA), bring together the required technologies to exploit synergies that will result by the judicious combination of materials to provide superior performance 100% biobased bioplastics. The production of omega-OHFAs will be performed by using SyntheZyme's newly engineered yeast strain that provides the first efficient biotechnological route to convert fatty acids to omega-HOFAs. P(omega-HOFAs) have properties similar to medium density polyethylene (PE). However, unlike PE, P(omega-HOFAs) contain ester groups separated by 13 to 17 methylene (CH2) units. Thus, P(omega-HOFAs) provide important PE-like properties such as water resistance and excellent ductility while retaining chemical reactivity so they can be reactive blended with PLA and strengthened by CNWs. PolyNew Inc. and SyntheZyme LLC will work together to develop technologies by which CNWs are functionalized to engineer interactions with blended P(omega-HOFAs) and PLAs. The impressive performance of CNWs derives from their aspect ratio that enables them to reach their percolation threshold (e.g., where long-range connectivity is achieved within the material) at relatively low loadings, resulting in impressive modulus increases. Preliminary work has shown that P (omega-OHFAs)/PLA blends show promising properties that would greatly benefit by incorporation of specifically functionalized CNWs. The broader impacts of this research to society at large are many. The project is consistent with Federal policies supporting greater use of biobased products including the Food, Conservation, and Energy Act of 2008, which is designed to ensure that a sufficiently large base of new, non-food, non-feed biomass crops is established to meet demands for renewable energy and bioproducts. Socially, there are advantages associated with employment in the plastics, forestry and agriculture sectors of the economy--the project strongly supports Green Jobs creation. Reductions in petroleum dependence (even relatively modest ones) are also considered beneficial. Teaching and training will be promoted and considerable outreach activities will be pursued. Previous success in incorporating underrepresented groups (women, Hispanics, and African Americans) in research activities will be continued.Partners at the inception of the project are the Knowledge-Enhancement Partnership (KEP) unit, consisting of NYU-POLY (Brooklyn, NY) and two small businesses partner companies: SyntheZyme LLC (Brooklyn, NY), a small business with private stock holders; and PolyNew Inc. (Golden, CO), a privately held woman-owned small business. Other partners are academic institutional organizations: University of Colorado, Anschutz Medical Campus (CO), Colorado School of Mines (CO), NYU Langone Medical Center (NY), NYU College of Dentistry (NY),Memorial Sloan Kettering Institute (NY), and the Denver School for Science and Technology (DSST) (CO); private sector organizations: Fish & Richardson; Smith, Gambrell & Russell, LLP; Berenbaum & Weinsheienk; Sealed Air; Dart Packaging; DSM; ADM; NatureWorks; Lubrizol; BASF and Pepsico; and public sector organizations: Aurora Economic Development Council (AEDC), New York State Energy Research and Development Authority (NYSERDA), Colorado Bioscience Association (CBSA), Colorado Institute for Drug, Device and Diagnostic Development (CID4), Colorado Office for Economic Development and International Trade (OEDIT), Colorado Small Business Development Centers (SBDC), and Fitzsimons BioBusiness Partners (FBBp) & Fitzsimons Redevelopment Authority (FRA) (Aurora, CO).

纽约大学理工学院（NYU-POLY）的创新合作伙伴关系项目解决了开发生物塑料的必要性，除了以生物为基础并提供理想的环境足迹外，还将为未来的客户提供改善现有材料的性能特征。这样做至关重要的是要激励消费者放弃当前的石油衍生材料，以供新的世界生物塑料（例如本文提出的生物塑料）。 项目团队采取的策略是利用与属性正确组合的生物塑料，同时着重于工程界面或这些组件之间的界面或边界以优化材料性能。 具体而言，选定的材料成分包括纤维素纳米孔（CNWS），聚（欧米茄 - 羟基脂肪酸（P（P（Omega-Ohfas）））和聚（乳酸）（PLA）（PLA）。而P（OmeG-OHFAS）可提供良好的水解稳定性和耐力性，可提供良好的水解稳定性和pla-compos，并提供高度调节量。该项目的知识增强合作伙伴（KEP）小型企业，Polynew Inc.（工程化的CNW）和Synthezyme LLC（P（Omega-Ohfas）及其与PLA的融合），将所需的技术汇集在一起​​，以利用这些材料来利用材料来实现较高的bey byerba byaast-byos-byaSt-byaast-byaast-aStics oby aStics oby aSt-libas oby aStics oby aStics oby aStics。 Synthezyme的新设计的酵母菌菌株提供了第一个有效的生物技术途径，将脂肪酸转换为欧米茄（Omega-Hofas）。因此，P（欧米茄霍法斯）具有重要的PE样特性，例如防水性和出色的延展性，同时保持化学反应性，从而可以与PLA进行反应性混合并通过CNW增强。 Polynew Inc.和Synthezyme LLC将共同开发CNW的技术，以通过该技术功能化，以与混合P（Omega-Hofas）和Plas进行工程相互作用。 CNW的令人印象深刻的性能来自其长宽比，使它们能够在相对较低的载荷下达到其渗透阈值（例如，在材料中实现远距离连接性），从而增加了令人印象深刻的模量。初步工作表明，P（Omega-Ohfas）/PLA混合物显示出有希望的特性，可以通过合并特定功能化的CNW来大大受益。这项研究对整个社会的更广泛影响是许多。该项目与支持更多利用生物基产品在内的联邦政策一致，包括2008年的食品，保护和能源法，该法案旨在确保建立足够大的新的，非食品，非喂养的生物量作物，以满足对可再生能源和生物生物产品的需求。从社会上讲，经济的塑料，林业和农业领域的就业有优势 - 该项目强烈支持创造绿色就业机会。石油依赖性的减少（甚至相对适中）也被认为是有益的。将促进教学和培训，并将进行大量的外展活动。以前的成功将代表性不足的群体（妇女，西班牙裔和非洲裔美国人）纳入研究活动。该项目成立于项目成立时，是知识增强合作伙伴（KEP）单位，由NYU-Poly（Brooklyn，Ny，Ny）和两个小型企业合作伙伴公司组成：Synthe Zyme llc（Synthe Zyme Llc）（Brokyme llc（Brokyllc）， and Polynew Inc.（Golden，Co），一家私有妇女拥有的小型企业。其他合作伙伴是学术机构组织：科罗拉多大学，安索斯医学校园（CO），科罗拉多州矿业学院（CO），纽约大学Langone医学中心（纽约州），纽约大学牙科学院（纽约）（纽约），纪念Sloan Sloan Kettering Institute（NY），以及丹佛的科学和技术学院（CO）（DSST）（DSST）（CO）（CO） 私营部门组织：Fish＆Richardson； Smith，Gambrell＆Russell，LLP； Berenbaum＆Weinsheienk;密封的空气；飞镖包装； DSM;阿德自然工人； lubrizol;巴斯夫和百事可乐；和公共部门组织：Aurora经济发展委员会（AEDC），纽约州能源研发局（Nyserda），科罗拉多州生物科学协会（CBSA），科罗拉多州的药物，设备和诊断开发研究所（CID4），科罗拉多州经济发展与国际贸易办公室（OEDIT），科罗拉多州小型企业开发中心（科罗拉多州小型企业中心） ＆Fitzsimons重建局（FRA）（Aurora，co）。
