“…Similarly, the use of charcoal from sawmill residues reduces fossil fuel emissions by 83e91% compared to coal as fuel in a cement kiln (Sjølie, 2012). Up to 8% of the cement in mortar could be replaced by rice straw coke without a significant impact on the mechanical properties (Wang and Wu, 2013). The CO 2 emission from fossil fuel use in the cement industry depends mainly on three factors: (1) the type of fossil fuel used; (2) the amount of biomass and waste materials replacing fossil fuels; and (3) the type of kiln used.…”

“…The cellulose and lignin contents in coffee exocarp were higher than the cellulose and lignin contents in straw and rice husks but lower than those in hardwood. The hemicellulose content in coffee exocarp was similar to the hemicellulose content in straw and rice husks and higher than that in hardwood (Wang and Wu 2013;Xie et al 2016). The ash content in coffee exocarp was lower than the ash contents in straw, rice husks, and hardwood.…”

Portland cement-based composites were prepared with coffee exocarp (pretreated with water or NaOH) via vacuum extraction technology. An orthogonal test was adopted to analyze the influence of various factors on mechanical properties of the composite. The morphology and composition of the pretreated coffee exocarp and composites were analyzed via environmental scanning electron microscopy and X-ray diffraction, respectively. The results showed that the coffee exocarp content and vacuum extraction time significantly affected the compressive strength. An addition of 10% coffee exocarp had a slight negative effect on the mechanical properties but enhanced the crack inhibition and overall toughness of the composite. The scanning electron microscopy and X-ray diffraction results showed that the composite containing coffee exocarp pretreated with 4% NaOH solution had the highest density and exhibited the best properties due to mechanical interlocking between the coffee exocarp and cement. After 28 d of curing, the composites exhibited a maximum compressive strength of 15.72 MPa, a mass that was approximately 37% less than that of ordinary Portland cement samples, and a bulk density of 1.5 g/cm3 to 1.6 g/cm3. Hence, the produced biocomposites could be used for low-load pavements, providing a new type of economical building material.
