To achieve net-zero carbon emissions in Australia by 2050, this project proposes to develop carbon-negative concrete using two typical industrial wastes, recycled powder from construction and demolition waste and drinking water treatment sludge from the water industry. This project first aims to develop innovative artificial aggregates containing sludge-derived biochar and recycled powder under carbonation curing. The developed artificial aggregates with superior carbon absorption capacity are then used to produce carbon-negative concrete. The properties of artificial aggregates and carbon-negative concrete will be comprehensively investigated. This project creates a green engineering solution to stockpiled industrial wastes.

为了在2050年之前实现澳大利亚的净零碳排放，该项目建议使用两种典型的工业废物开发负碳混凝土，即建筑和拆除废物的回收粉末和自来水行业的饮用水处理污泥。该项目的第一个目标是开发创新的人工骨料，其中含有污泥衍生的生物炭和碳酸化固化下的回收粉末。研制出的具有上级碳吸收能力的人工骨料用于生产负碳混凝土。人工骨料和负碳混凝土的性能将进行全面的研究。该项目为工业废物的储存创造了一个绿色工程解决方案。
