Slow pyrolysis using a batch reactor at 450 °C was applied to the polypropylene (PP) powder derived from Coronavirus Disease 2019 (COVID-19) isolation gown waste to yield char briquettes, using sugar palm starch (SPS) and a manual hydraulic press. These studies are significant because of reductions in plastic waste from the preparation of barbecue coal due to environmental sustainability. The results presented here include the physical, morphological, thermal, combustion, and mechanical properties of char when reinforced with various percentages of SPS loadings (0, 10, 20, 30, and 40%), which act as a matrix/binder to produce char/sugar palm starch (C/SPS) composites. The physical and morphological characteristics of C/SPS composites were determined using Fourier transform infrared (FTIR) and field emission scanning electron microscopy (FESEM). On the other hand, the thermal and combustion properties of the C/SPS briquettes were studied via thermogravimetric and bomb calorimeter analysis. The results show that the compressive strength of the briquettes increased as the SPS loading increased, whereas the higher heating values (HHV) reduced. The findings indicate that C-80/SPS-20 briquettes presented excellent combustion characteristics (1,761,430 J/g) with satisfactory mechanical strength (1.463 MPa) in the compression test. Thus, C-80/SPS-20 briquettes are the most suitable composites for domestic and commercial uses.
采用间歇式反应器在450℃下对源自2019冠状病毒病（COVID-19）隔离服废料的聚丙烯（PP）粉末进行慢速热解，以制得炭块，使用了糖棕淀粉（SPS）和手动液压机。由于从环境可持续性角度减少了用于制备烧烤炭的塑料废料，这些研究具有重要意义。此处呈现的结果包括当用不同百分比的SPS负载量（0%、10%、20%、30%和40%）增强时炭的物理、形态、热、燃烧和机械性能，这些SPS负载量充当基质/粘结剂以生产炭/糖棕淀粉（C/SPS）复合材料。使用傅里叶变换红外光谱（FTIR）和场发射扫描电子显微镜（FESEM）测定了C/SPS复合材料的物理和形态特征。另一方面，通过热重分析和弹式量热计分析研究了C/SPS炭块的热性能和燃烧性能。结果表明，随着SPS负载量的增加，炭块的抗压强度增加，而高热值（HHV）降低。研究结果表明，在压缩试验中，C-80/SPS-20炭块呈现出优异的燃烧特性（1,761,430 J/g）和令人满意的机械强度（1.463 MPa）。因此，C-80/SPS-20炭块是最适合家庭和商业用途的复合材料。
