—This research was conducted to transform food waste into ‘char’, which would lead to improving soil quality, preventing acidification and serving as a habitat for numerous microorganisms. The injection of soil bacteria will reduce damages caused by NaCl within disposed food waste.
Changes in soil bacteria led by variations in the NaCl concentration were investigated, and by treating the NaCl solution on lettuce seeds with different amounts of soil bacteria, changes in the chlorophyll of lettuce were identified. Finally, the effects of producing char with food waste that includes soil bacteria and adding soil bacteria after producing the char were compared. The analysis was done by observing the resulting lettuce growths.
The result demonstrated that some soil bacteria cause dechlorination, and the small amount of decomposed chloride ions facilitate plant growth. The optimal method of utilizing food waste char is to produce it first and add soil bacteria on it afterwards.
—Char, dechlorination, food waste, soil bacteria.
