“…Biochar was also used to partially substitute carbon black in rubber composite systems resulting to improvements in mechanical properties . Bamboo charcoal, similar to but different from biochar due to its processing temperature which is typically above 1000 °C, has been used and studied by different authors as reinforcing fillers in some polymers such as poly(ethylene terephthalate) (PET), PET/PP blends, low density polyethylene, and PP . These studies which utilized bamboo charcoal as reinforcement showed increase in moduli of the composites indicating biochar as a promising stiffening agent in thermoplastics.…”

The reinforcing effects of biocarbon of varying particle size ranges (crushed, <500, 500–426, 250–213, and <63 µm) on biobased polyamide 6,10 (PA 6,10) at 20 wt % loading were investigated for the resulting biocomposites. The heat deflection temperature and impact strength were observed to increase with reduction in particle size. Also, a 200% increase in the impact strength was observed in the biocomposite with biocarbon particles sized at <63 µm when compared to that with <500 µm. A 50% and 83% increase in the tensile and flexural moduli of the biocomposite with biocarbon particle size of <500 µm was observed, respectively, while the tensile strength was observed to remain unchanged. The flexural strength of the biocomposites was improved by 61% when compared to neat nylon. These results were due to good wetting, dispersion and increased surface area of the biocarbon within the nylon matrix. These results show the potential of biocarbon as reinforcing filler in nylon for applications especially in the automotive industry. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

“…One is due to moisture loss at up to approximately 115 º C and an exothermic one on account of the thermal degradation of EGC and EGC with PET and HDPE 19 . As for the charcoal blended with thermoplastics, the greatest temperature variation is shifted in over 50 º C due to the fact that the combustion of binders occurs at higher temperatures 18,20 . According to Guo et al 20 , PET undergoes thermo-oxidative degradation in two consecutive steps, first is relating to the degradation of the backbone and formation of a char and second is relating to the thermo-oxidative degradation of the char, at a temperature higher than that charcoal 20 .…”

In the search for new solid fuels that can mitigate emissions of greenhouse gases and reduce municipal solid waste, it is proposed to produce a solid fuel from elephant grass charcoal (EGC) and blend it with the following binding recyclable materials, polyethylene terephthalate (PET) and high-density polyethylene (HDPE) with the aim of increasing their mechanical strength. Immediate analysis results indicate that there was an increase in volatile material content from 21.18% to 28.02% and a reduction in fixed carbon from 65.00% to 58.40% with the addition of binding agents. The higher heating value of pure charcoal was 5924.16 kcal/kg and there was no significant alteration by adding HDPE, however, with the addition of PET, there was an average reduction of 4.82%. According to the elemental analysis of charcoal, there were no significant amounts of sulphur, but silicon and potassium oxides were predominantly composed followed by aluminium, titanium, magnesium and iron according to the analysis of ashes. The addition of thermoplastic binders allowed producing pellets and it was found that those produced by using HDPE are stronger than those produced with PET.

“…Charcoal and biochar are produced at much higher temperatures than those used to produce torrefied biomass. Guo et al found that incorporating bamboo charcoal into poly(ethylene terephthalate) improved its thermal stability. Peterson determined that carboxylated styrene‐butadiene composites containing low concentrations of corn stover biochar (10% (w/w)) exhibited improved tensile properties.…”

Torrefied almond shells and wood chips were incorporated into polypropylene as fillers to produce torrefied biomasspolymer composites. The composites were prepared by extrusion and injection molding. Response surface methodology was used to examine the effects of filler concentration, filler size, and lignin factor (relative lignin to cellulose concentration) on the material properties of the composites. The heat distortion temperatures, thermal properties, and tensile properties of the composites were characterized by thermomechanical analysis, differential scanning calorimetry, and tensile tests, respectively. The torrefied biomass composites had heat distortion temperatures of 8-24 C higher than that of neat polypropylene. This was due to the torrefied biomass restricting mobility of polypropylene chains, leading to higher temperatures for deformation. The incorporation of torrefied biomass generally resulted in an increase in glass transition temperature, but did not affect melting temperature. Also, the composites had lower tensile strength and elongation at break values than those of neat polypropylene, indicating weak adhesion between torrefied biomass and polypropylene. However, scanning electron microscopy results did indicate some adhesion between torrefied biomass and polypropylene.
