The proposed research is a significant initiative to develop new technologies and strategies for pre-fabricated elements and sustainable structural design through the complete reuse and recycling of Construction and Demolition Waste (CDW), which is responsible of more than one-quarter of all waste generated in Canada. The overall objective of this program of research is to present globally applicable solutions to counteract the negative effects of CDW on the environment, the economy and society by developing pre-fabricated structural and non-structural elements that incorporate green construction materials, and by promoting and popularizing reuse and/or recycling in the construction industry. ***The specific objectives are to: (1) propose novel reuse and/or recycling methodologies that are substantially less energy intensive, more economical and more easily applicable for taking full advantage of CDW materials; (2) maximize the amount of reused and/or recycled CDW without compromising the prolonged sustainability and enhanced greenness of the final product; (3) modify reused and/or recycled ultimate products with green fibers for more versatile and widespread use; (4) merge ultimate reused and/or recycled green products into easily demountable structural and non-structural building systems to introduce sustainable deconstructable system designs; and (5) develop a holistic design and integrated inspection protocol for Green Lego-type Houses to identify their green construction performance. ***In-depth theoretical and experimental investigations will focus on recycling 100% of the inert portion of CDW to manufacture green concrete-based geopolymeric binder reinforced with vegetable and recycled green fibers, and to develop novel, environmentally sustainable masonry units and green foam concrete to be used in real-scale deconstructable building systems and sustainable design. ***Successful outcomes of this research will impact the construction industry by reducing CO2 emissions and limiting climate change. The long-term effects will benefit construction and demolition stakeholders, as outdated approaches are abandoned in favour of more environmentally friendly practices, contributing to the deceleration of global warming. Participating students will gain knowledge and experience that will qualify them to be a viable resource for both academia and the Canadian construction industry.

拟议的研究是通过完全再利用和回收建筑和拆除废物（CDW）来开发预制构件和可持续结构设计的新技术和新策略的重要举措，这些废物占加拿大产生的所有废物的四分之一以上。本研究项目的总体目标是提出全球适用的解决方案，通过开发包含绿色建筑材料的预制结构和非结构构件，以及促进和普及建筑行业的再利用和/或回收，来抵消CDW对环境、经济和社会的负面影响。***具体目标是：(1)提出新的再用及/或循环再造方法，以大幅降低能源消耗、更经济及更容易应用于充分利用CDW物料；(2)在不影响最终产品的长期可持续发展和提高其绿色程度的前提下，最大限度地重复使用和/或循环再用废物；(3)用绿色纤维修饰再利用和/或回收的最终产品，使其更通用和广泛使用；(4)将最终再利用和/或回收的绿色产品合并到易于拆卸的结构和非结构建筑系统中，以引入可持续的解构系统设计；(5)制定绿色乐高型房屋的整体设计和综合检测方案，以确定其绿色建筑性能。***深入的理论和实验研究将集中于100%回收CDW的惰性部分，以制造绿色混凝土为基础的地聚合物粘合剂，用蔬菜和再生绿色纤维增强，并开发新颖的，环境可持续的砌体单元和绿色泡沫混凝土，用于实际规模的解构建筑系统和可持续设计。***本研究的成功成果将通过减少二氧化碳排放和限制气候变化来影响建筑行业。长期影响将有利于建筑和拆迁的利益相关者，因为过时的方法被抛弃，更有利于环保的做法，有助于减缓全球变暖。参与的学生将获得知识和经验，使他们有资格成为学术界和加拿大建筑行业的可行资源。
