Modification and Life Cycle Analyses of Upcycled Architectures from Boreal, Marine and Commodity Polymer Waste: Circularity and Structure-Morphology-Properties

该研究计划旨在实施生态设计和生命周期评估(LCA)，以设计和评估来自北方鱼类、农场和森林资源的生物产品和过程，发现可整合到当前生物/循环经济应用中的新功能。我们将使用可持续协议的组合来获取和修改来自反向流动系统的功能成分，以重新利用废物，并将其用作再制造的设计组件。然而，为了弥合循环设计的资源效率和通过生态设计减少环境影响之间的差距，生命周期评价指标将从产品和工艺生命周期的最早阶段开始整合。这将为合成创新提供信息，以调整结构-形态-性能，获得与商业类似物相当的性能。长期目标是建立一个整合了对循环性和环境设计的细粒度理解的计划，以开发使用补充生命周期、循环性和可持续发展指标的功能性生物产品，这些指标有助于在5和10的指导下实现联合国可持续发展目标9、12、13。资源、技术和商业创新将需要跨学术、跨行业、跨社区和跨政府部门的协作行动，以防止负担转移和不公平。在短期内，我的目标是以协调一致的方式整合三个目标：(I)识别、分离和表征来自可再生或来自生物质资源的回收系统的功能成分，以便在分子水平上使用绿色化学进行修改(Ii)为生物产品和过程开发制定和实施生态设计战略，以实现具有竞争力的功能和性能(Iii)在设计和产品生命周期的所有阶段使用生命周期评价和生态设计工具，以告知目标(I)和(Ii)。将对材料、能源、化学品、水和环境参数的选择和使用进行评估。我们将使用生态高效的微波消化和有机合成来分离功能成分(如甘油三酯、壳聚糖)，以利用化学反应部位(烯烃、胺)在温和、含水或无溶剂的条件下进行C-H、多组分或溶胶-凝胶化学。优化将满足定义的功能单元标准和最终用途(例如生物表面活性剂、平台化学品)和最终用户(基于性别的化学毒性)的背景。材料将使用粘度、层析、光谱、显微和热机械技术进行表征。参加我的项目的HQP将学习到可持续发展驱动的设计和决策方面不可或缺的技能。他们将为协作和关注公平的科学做出贡献。他们将在材料和工艺生态设计、生命周期评价以及使用综合、分析和评估方法和工具进行表征方面获得重要技能。重要的是，在日益增长的可持续资源经济中，他们将获得在多个行业具有重要意义的技能。

This research program seeks to implement ecodesign and life cycle assessment (LCA) to engineer and evaluate bioproducts and processes from boreal fish, farm and forest resources, bearing discovery of new functions that can be integrated into current applications towards a bio/circular economy. We will use a combination of sustainable protocols for access and modification of functional ingredients from reverse flow systems to repurpose waste and use it as a design component for remanufacture. However, to bridge the gap between resource efficiency from circular design and environmental impact reduction through ecodesign, LCA indicators will be integrated from the earliest stages of the product and process life cycle. This will inform synthetic innovation for tuning structure-morphology-properties for performance comparable to commercial analogues. The long-term goal is to build a program that integrates a granular understanding of circularity and environmental design to develop functional bioproducts using complementary life cycle, circularity and sustainability metrics that contribute to UN SDGs 9,12,13 guided by 5 & 10. An interdisciplinary, collaborative action across academia, industry, community and government sectors will be required for resource, technology & business innovation to prevent burden shifting and inequity. In the short-term, I aim to integrate three objectives in a concerted manner (i) Identify, isolate and characterize functional ingredients from renewable or returning systems from biomass resources to modify at the molecular level using green chemistry (ii) develop & implement ecodesign strategies for bioproduct & process development for competitive function and performance (iii) Use LCA and Ecodesign tools at all stages of design and product life cycle to inform objectives (i) and (ii). Selection & use of materials, energy, chemicals, water and environmental parameters will be evaluated. We will use ecoefficient microwave digestion & organic synthesis to isolate functional ingredients (e.g. triglycerides, chitosan) to harness chemically reactive sites (alkene, amine) to conduct C-H, multicomponent or sol-gel chemistry under mild, aqueous or solventless conditions. Optimization will meet defined functional-unit criteria with an end-use (e.g. biosurfactant, platform chemical) and end-user (sex-based chemical toxicity) context. Materials will be characterized using viscosity, chromatographic, spectroscopic, microscopic and thermomechanical techniques. HQP who participate in my program will learn indispensable skills in sustainability-driven design and decision making. They will contribute to collaborative and equity-focused science. They will gain important skills in materials and process ecodesign, LCA and characterization using synthetic, analytical and assessment methods & tools. Importantly, they will gain skills with significance across multiple sectors in the growing sustainable resources economy.
