Abstract:

Study was apply hydrothermal carbonization (HTC) to microplastics generated by various degradation and erosion processes of persistent plastic waste. To achieve this, samples of microplastic raw material and microplastic waste were selected by particle size. HTC subjected to generate solid and oil fractions. The raw materials and microplastics, trends were identified. The First fuel potential of t raw materials and microplastics was confirmed through physical and chemical analysis before apply HTC. The conditions of reaction temperature and time were varied to obtain optimal conditions for yield of oil (C15, C16). Physical and chemical analysis of the microplastic raw material and microplastic waste showed that both had combustible fractions of over 90% and ash content differences of 0.5-1.0% for raw material and 5.9-7.3% for waste, attributed to additives or colorants in the waste. The fixed carbon content was 0.1-0.2% for raw material and 1.1-2.3% for microplastic waste. Analysis of heavy metals indicated that both microplastics met quality standards for solid fuel products. TGA analysis showed weight loss at around 2000C for PE in both raw material and waste, and at 100-2000C for PS and PP in both raw material and waste, enabling selection of HTC reaction temperature for each plastic type. Optimal reaction times for each plastic type were also determined. Therefore, it was confirmed that microplastic raw materials and microplastic waste produced solid fuels when subjected to HTC, while liquid fuels showed the highest yield of C15, C16 from PE at 2400C for 40 min, PS at 2700C for 60 min, and PP at 2400C for 60 min.
