TECHNOLOGY FOCUS - AGRICULTURE - Preferred Method: The method further comprises: transferring the wastewater (filtered in the filtration step) to a biological water treatment tank using aerobic microorganisms, and then treating the wastewater, and obtaining decanter cake from sludge on the bottom of the water treatment tank and then introducing the decanter cake to the mixing process; and introducing the pyroligneous liquid obtained by collecting and liquefying smoke generated during the carbonization of the kernel shell, to the mixing process. The filtration step is performed using a filter consisting of a mixture of (i) the carbon obtained by carbonizing the kernel shell, (ii) the ash obtained by incinerating the EFB and (iii) the fiber. The maturation step is carried out using microorganisms having plant growth-promoting activity or antifungal activity. Preferred Composition: The biofertilizer comprises the kernel shell carbon (15-25 wt.%), the EFB ash (15-25 wt.%), the decanter cake (35-45 wt.%) and the fiber (15-25 wt.%).    TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The microorganisms having plant growth-promoting activity or antifungal activity is Bacillus cereus EP1(KCTC 11292BP), Bacillus cereus EP2(KCTC 11293BP), Bacillus cereus EP3(KCTC 11294BP), Bacillus cereus EP5(KCTC 11295BP) or Bacillus cereus BP315(KCTC 11296BP) ACTIVITY - Fertilizer.    MECHANISM OF ACTION - None given.    EXAMPLE - Wastes generated in a palm oil mill process reached 225 ton/day for empty fruit bunch (EFB), 54 ton/day for kernel shell and 600 ton/day for palm oil mill effluent (POME). When EFB was incinerated for its ash using an incinerator, having an air pollution control system, and a carbonator (the yield was 5%) and EFB (200 ton) was incinerated to EFB ash (10 ton). Also, the yield of kernel shell was 20%, and thus kernel shell carbon (10 ton) was obtained by carbonizing kernel shell (50 ton). POME was treated with micro air bubbles and treated in an oil recycler to remove oil. Then, the POME treated with air bubbles was filtered through a filer consisting of a mixture of the EFB ash, the kernel shell carbon and fiber (50 ton). The filtered water was sent to a biological water treatment pond, in which it was treated with aerobic microorganisms to obtain clean water. The filtered POME sludge in (50 ton) was obtained in the form of decanter cake. The decanter cake (20-50 ton), the EFB ash (10 ton), the carbon (10 ton) and the fiber (50 ton) (40 ton of the fiber was recycled through sieving and the fiber (10 ton) was used as a fertilizer), which had been used as the filter, were added. Also, pyroligneous liquid (10 l) and minerals (10 kg) were added to the completed fertilizer (per ton). The water contents of the raw materials were 70% for the decanter cake, 8% for the fiber and less than 5% for the ash and the carbon, and when the raw materials were mixed, the water content of the mixture was 60% which was suitable for the activity of microorganisms. For the activity of microorganisms during the fermentation process, fine suspended materials flocculated and precipitated by microorganisms in the water treatment pond were collected to maintain the raw materials at suitable water contents, and organic matter was added to it. The final biofertilizer was (50 ton (including pyroligneous liquid (50 l) and minerals (500 kg))) produced through the mixing, fermentation and drying of the raw materials.
