Abstract: The environmental impact of biomass hydrothermal carbon material production was assessed by using life cycle assessment(LCA). A life cycle inventory including input and output processes of biomass hydrothermal carbon material production was established based on inventory analysis. GaBi 6.0 software was used to model and calculate the original data to obtain the corresponding environmental impact potentials on global warming potential(GWP), acidification potential(AP), abiotic depletion potential(ADP), etc. The results showed that the effect order of production process on the environmental impacts was GWP, AP, photochemical ozone creation potential(POCP), eutrophication potential(EP), ADP and ozonospher disturbance potential(ODP). The power consumption was the uppermost environment impact factor. As the power generation of our country was carbon intensive, the emissions of CO2, SO2, NOx from thermal power were the main environmental impact factors. The key environmental influencing link in hydrothermal carbon production was hydrothermal carbonization. According to this result, it would be helpful for reducing the environmental impact of biomass hydrothermal carbon material by reducing hydrothermal carbonization temperature or shortening the time of hydrothermal carbonization.

Key words: hydrothermal carbon, life cycle assessment, environmental impact
