چکیده مقاله
Due to the changes in the natural environment and the intensification of human activities, the problems of environmental pollution have become extremely serious Hydrothermal carbonization HTC as a promising thermochemical process can convert solid organic waste into valuable products Carbon materials obtained from hydrochar have high potential in various applications such as solid fuel, supercapacitor, fuel cell and absorbent, water treatment, and soil amendment The present study aimed to produce hydrochar from lignocellulosic biomass and also evaluate the environmental effects of this process both at the midpoint and at the endpoint levels, assuming 1kg of hydrochar as a functional unit In order to prepare the product, Pinus eldarica Medw pine leaves as a lignocellulosic precursor, were placed under hydrothermal conditions at a temperature of 225 °C under pressure for 12 hours A weight ratio of 10:1 water to the precursor and also sodium hydroxide as a catalyst were considered The environmental impacts of the process were evaluated through a life cycle assessment LCA LCA of the product during the HTC process showed that due to the use of fossil fuels in electricity production, the use of electricity shows the greatest environmental impact in all stages of hydrochar production
