The objective of this study is to reuse CO2 of the compost gas in the plant growth facilities which exhausted in composting process. The influence of the compost gas applying to the plants was examined. And elimination methods of the several components from the compost gas were examined.
H2S, CH3SH and NH3 were unfavorable for the plants when they were cultivated in greenhouse. Especially, H2S and CH3SH injured the plants. The biological filter (bio-filter) was useful or effective for NH3 contained the compost gas. But the bio-filter was less effective for CH3SH and (CH3)2S. And the variation of environmental temperature influenced the availability of the bio-filter. The catalytic-filter with the activate carbon and catalyst was effective for CH3SH, while it is not effective for NH3. By-product such as (CH3)2S was produced by the catalysis activity. The compost gas which was treated by both bio-filter and catalytic-filter didn't injure the plants fatally. The SPAD value of the radish applied the compost gas treated by bi-filter and catalytic-filter was higher than that grown by the atmospheric air.
