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.

该研究计划旨在实施生态设计和生命周期评估（LCA），以设计和评估北方鱼类，农场和森林资源的生物产品和工艺，发现可以整合到当前应用中的新功能，以实现生物/循环经济。我们将使用一系列可持续的协议来获取和修改来自逆流系统的功能性成分，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与通过生态设计减少环境影响之间的差距，将从产品和工艺生命周期的最早阶段开始纳入LCA指标。这将为调整结构-形态-性质的合成创新提供信息，以实现与商业类似物相当的性能。 长期目标是建立一个项目，整合对循环性和环境设计的精细理解，利用互补的生命周期、循环性和可持续性指标开发功能性生物产品，以促进联合国可持续发展目标9、12、13（以5和10为指导）。学术界、工业界、社区和政府部门需要采取跨学科的合作行动，以促进资源、技术和商业创新，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：从生物质资源的可再生或回收系统中分离和表征功能成分，以使用绿色化学在分子水平上进行修改（ii）制定和实施生物产品和工艺开发的生态设计策略，以实现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LCA和生态设计工具，为目标（i）和（ii）提供信息。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解和有机合成来分离功能成分（例如甘油三酯，壳聚糖），以利用化学反应位点（烯烃，胺）在温和，水性或无溶剂条件下进行C-H，多组分或溶胶-凝胶化学。优化将满足最终用途（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）背景下定义的功能单元标准。将使用粘度、色谱、光谱、显微镜和热机械技术对材料进行表征。参加我的项目的HQP将学习可持续发展驱动的设计和决策中不可或缺的技能。他们将为以合作和公平为重点的科学做出贡献。他们将获得材料和工艺生态设计，LCA和使用合成，分析和评估方法和工具表征的重要技能。重要的是，他们将在不断增长的可持续资源经济中获得跨多个部门的重要技能。
