METODE PIROLISIS UNTUK PENANGANAN SAMPAH PERKOTAAN SEBAGAI PENGHASIL BAHAN BAKAR ALTERNATIF
ABSTRACT: The research on the
processing of organic municipal waste conversion has been done by using
pyrolysis method. The research aims to gain an alternatif fuels and to minimize
the landfill space. In the pyrolysis process, it was investigated the char
formation as solid fuel as well as its heating value. The char formation was
determined by the change of mass and volume of waste for minimizing landfill
area.The waste compositions were obtained by surveying the 10 families during
10 days and then it was made the waste spesimens as the pyrolysis feedstocks.
The pyrolysis processes were operated in range temperature 200oC to 400oC.
Then, the char formations as pyrolysis products were tested by using bomb
calorimeter to qualify the heating value of the products. The results showed
that the waste was able to be a solid fuel due to the quality of its heating
value. The increasing of the heating value could reach 150% from unpyrolyzed
waste to pyrolyzed one. In addition, the pyrolysis method was able to
significantly minimize the volume of waste, so that it has a potential way to
overcome the need of a large landfil area in which it could reduce up to 50% in
mass and 85% in volume. In waste pyrolysis method, it was only needed 2 hours
operating process and low-temperature process (only up to 300oC). It
did not require require a high-operating temperature, therefore, the handling
of municipal organic waste to save area landfill and produce alternative fuel
could be done in short time and did not require great energy.
