Japanese researchers have achieved 18 MPa flexural strength from Chinese cabbage waste—creating construction-grade materials four times stronger than concrete. The achievement emerged from the University of Tokyo’s Institute of Industrial Science, where Associate Professor Yuya Sakai’s concrete recycling research led to discoveries in biomaterial strength. The researchers developed precise processing parameters which involved initial drying, followed by pulverization using a regular blender, and final hot pressing with water and seasonings. This three-phase approach eliminates the need for plastic additives, a limitation that affected previous food waste cement research. The material science centers on the interaction between sugar content and dietary … Continue reading Scientists Turn Chinese Cabbage Waste into 18 MPa Sustainable Construction Material
