The present invention provides a method for manufacturing the activated carbon from the coffee waste. The method includes steps of immersing the coffee waste in an activator solution so that the activator adsorbs on a surface of the coffee waste, and transferring the immersed coffee waste into a high temperature-rotary reactor for proceeding a reaction of carbonization and activation to result in the activated carbon product having a high specific surface area. Therefore, the present invention can efficiently transform the coffee waste into the activated carbon product used in industries of environment engineering and foodstuff, so as to achieve the object of recycling the waste.

This invention relates to a method for manufacturing the activated carbon, and more particularly to a method for manufacturing the activated carbon from the coffee waste.
The activated carbon has a special pore structure and is a collective noun of a porous carbon. Since the activated carbon has a high specific surface area (500-1500 m2/g), it is suitable for absorbing organic pollutants and widely used in industries of environment engineering, foodstuff and medicine.
There are four types of the activated carbon:
FIG. 1 is a simple flowchart of the method for manufacturing the activated carbon from the coffee waste according to a preferred embodiment of the present invention;
FIG. 2 is a schematic view showing the high temperature-rotary reactor of the present invention; and
FIG. 3 shows the temperature-increasing program of the high temperature-rotary reactor of the present invention.
Please refer to FIG. 1 showing a simple flowchart of the method for manufacturing the activated carbon from the coffee waste according to the present invention. The manufacturing steps are described in detail as follows:
1. Pretreatment of the Coffee Waste
The coffee waste is washed and baked, and the impurities in the coffee waste is picked out after the coffee waste is cooled down. Then the coffee waste is grinded.
