This book provides an in-depth examination of sawdust and its potential uses and hazards. In chapter one, Yaning Zhang, Bingxi Li, Haochun Zhang, Hongtao Li, Yijun Zhao, and Baocheng Jiang offer research on the exergy of (or maximum work obtainable by) sawdust. Next, Professor Augustine Uchechukwu Elinwa presents research on the potential use of sawdust as cement. In chapter three, Gabriela Nacu and Laura Bulgariu give a synopsis of the use of sawdust as a low-cost absorbent in the treatment of industrial wastewaters while also stressing the most significant benefits of its application. Following this, Redouane Ouafi, Zakia Rais, Mustapha Taleb, Mohamed Benabbou, and Meryem Asri further discuss the efficiency of using sawdust in the absorption of heavy-metals water pollution with the aim of relieving water stress. In closing, Mirjana Stajić, Jelena Vukojević, and Jasmina Ćilerdić look at the potential for sawdust to produce healthful foods and open the door for new species to be farmed commercially if used as a feedstock for food production.
