The increasing global consumption of plastic products has resulted in a growing accumulation of plastic waste, posing severe environmental challenges. The study aims to explore methods for recycling plastic macaque waste to produce carbon nanomaterials. Carbon nanomaterials were obtained via electric arc discharge from plastic waste processed at 1173 K in a nitrogen and water vapor environment. Key properties such as moisture, ash, and volatility were analyzed with a Thermoster Eltra analyzer. Pore volume, bulk density, pH, and adsorption activity were also assessed. This study addresses plastic waste pollution by converting it into porous carbon nanomaterials through pyrolysis at 900 °C. These materials, used as electrodes, produce graphene-forming nanomaterials via electric arc discharge. Analysis confirmed the composition using Raman spectroscopy, X-ray diffraction, and gas chromatography. The study reveals that the electrical conductivity of the synthesized carbon nanomaterials is close to that of graphite, with a reduction in electrical resistance of up to 3.6 times compared to the initial carbonized material. The process yields valuable products like nanomaterials, hydrogen, and flammable gases. This research presents an innovative and sustainable approach for the recycling of plastic waste into graphene-forming carbon nanomaterials using electric arc discharge.
全球塑料制品消费量的不断增加导致塑料垃圾的积累日益增多，带来了严峻的环境挑战。该研究旨在探索回收猕猴塑料垃圾以生产碳纳米材料的方法。通过在氮气和水蒸气环境中于1173 K处理塑料垃圾，利用电弧放电获得了碳纳米材料。使用Thermoster Eltra分析仪分析了水分、灰分和挥发物等关键特性。还评估了孔隙体积、堆积密度、pH值和吸附活性。本研究通过在900℃下热解将塑料垃圾转化为多孔碳纳米材料来解决塑料垃圾污染问题。这些材料用作电极时，通过电弧放电产生形成石墨烯的纳米材料。使用拉曼光谱、X射线衍射和气相色谱对成分进行了分析确认。研究表明，合成的碳纳米材料的电导率接近石墨，与初始碳化材料相比，电阻降低了多达3.6倍。该过程产生了纳米材料、氢气和可燃气体等有价值的产品。这项研究提出了一种创新的可持续方法，即利用电弧放电将塑料垃圾回收成形成石墨烯的碳纳米材料。
