报告题目：Biochar and biomass materials for sustainable buildings applications  

报告摘要：Biochar,a carbon-rich material derived from the pyrolysis of biomass,has gained attention for its potential applications in sustainable building materials. Its unique properties,such as high porosity,thermal stability,and carbon sequestration ability,make it a valuable additive in construction materials. Associate Professor Kua Harn Wei from the National University of Singapore has been pioneering the use of biochar—a carbon-rich material derived from pyrolyzed biomass—in sustainable building applications. His research focuses on integrating biochar into cement and phase change materials (PCM) to enhance structural performance and environmental sustainability. One of Prof. Kua's notable achievements is developing a method to recycle wood waste,particularly sawdust,into biochar for concrete applications. By incorporating this biochar into cement mixtures,the resulting concrete exhibits up to 20% increased strength and 50% improved water impermeability. This innovation not only enhances building durability but also offers a sustainable solution for managing wood waste in Singapore,where over 530,000 tonnes were produced in 2016 alone.

Beyond material improvements,biochar work contributes to carbon sequestration efforts. Biochar effectively locks in carbon that would otherwise be released into the atmosphere through biomass decay or incineration. Applying this technology in concrete construction presents a novel approach to storing carbon within building structures while promoting recycling and reducing environmental impact.

Key Applications are included: Enhances strength,reduces carbon footprint,and improves thermal insulation;Improves mechanical properties and reduces embodied carbon;Increases thermal resistance and moisture control,contributing to energy efficiency;Enhances durability,reduces heat island effect,and supports sustainable infrastructure and Regulates humidity,improves air quality,and enhances fire resistance. Many Sustainability Benefits to use the biochar in buildings such as Stores carbon long-term,reducing CO₂emissions;Utilizes agricultural and forestry waste,promoting circular economy principles;Improves insulation and thermal regulation,reducing energy consumption.;and Reduces the reliance on non-renewable resources and mitigates pollution. Biochar-based materials present a promising pathway toward greener and more resilient construction practices.

报告人简介：Kua Harn Wei副教授是新加坡国立大学（NUS）建筑环境系的杰出学者。他拥有麻省理工学院（MIT）的建筑工程博士学位，以及MIT的土木与环境工程、技术与政策双硕士学位，并在新加坡国立大学获得理论物理学硕士学位。Kua教授领导着NUS的智能材料实验室，他的研究主要集中在以下几个领域：(i) 生命周期可持续性评估；(ii) 开发能够直接捕获二氧化碳和净化空气的生物基建筑材料；(iii) 制定促进家庭节能的政策。他的团队的一项显著成就是开发了一种通过将木废料制成的生物炭整合到混凝土中以增强其性能的方法。这一创新不仅提高了混凝土的强度，还增强了其不透水性，同时通过回收木废料为环境可持续性做出了贡献。Kua教授的研究成果得到了广泛的国际认可，被任命为国际先进材料协会（IAAM）新加坡国家理事会理事，并被评为IAAM会士。2022年，他在瑞典举办的先进材料世界大会上发表了关于生物炭作为可持续建筑材料的主题演讲，并荣获IAAM科学家奖。

除了研究，Kua教授还在NUS担任过多个行政和领导职务，包括自2016年起担任助理院长（学术），以及2013年至2016年期间担任副系主任（研究）。2021年7月，他被任命为NUS肯特岗宿舍的舍监，在那里他致力于营造一个充满活力的住宿社区。他对教学的奉献精神也得到了广泛认可，曾多次获奖，包括2011/2012和2013/2014学年的年度卓越教学奖，以及2011/2012至2014/2015学年连续四年的设计与环境学院教学奖。

Kua教授在研究、领导和教学方面的广泛贡献对可持续建筑材料和环境保护领域产生了深远影响。
