Hydrothermal carbonization and pyrolysis are the process transforms into a useful material in the life and environmental practice. In contrast, both of the process are different in term of reaction. Hydrothermal carbonization process is to remove water contain and pyrolysis to remove volatile content in product. The problem of abundant volume of wood fibre waste production which normally being dumped to the landfill. Thus wood manufacturing should control the output product to avoid natural pollution from illegal activities. The objective of this research is to determine the amount of carbon particle in each process This process not only forms carbon element but other chemical compound such as hydrogen, nitrogen and sulphur in small ratio. This research is also proposed to avoid environmental pollution from give harm to human and economic aspect. Hydrothermal carbonization is conducted by supercritical unit and pyrolysis conducted by furbnace with temperature, volume and time control. The required temperature for this research is 200 °C and proportional with time in 4 hours. Each experiment needs to change the volume of material to 1 50g and 175g. After completing experiment, the product analyses using elemental analysis and TGA will be carry out to determine the chemical composition and the carbon present in product. Hydrothermal carbonization and pyrolysis are synthesis technique to convert waste material into a variety of application. Likewise, recycle a wood fibre waste to generate new application that gives a big impact to the economy and environment. The management of waste can be improved by the friendly technology that applies to avoid environmental problem.
