Researchers at the University of Auckland are also working on utilizing biochar in concrete applications to reduce carbon emissions during concrete production and to improve the strength considerably. It has also demonstrated that the biochar can be used as a suitable filler in polymer matrix. Recently, biochar-starch bio-composites were prepared and its nano-mechanical behaviours were investigated using advanced dynamic atomic force microscopy. Recently, the agglomeration behaviour of biochar in Polypropylene was investigated using micro-CT studies. These studies give more insight into the biochar interaction with the polymer matrix.
