국문 초록 (Abstract)

본 연구는 안성시 관내에서 발생하는 농산부산물 바이오 매스 중 오이, 토마토, 파프리카 작물 잔사를 수거하여 실험에 공시하고 각 부산물의 발생특성과 메탄 생산 퍼텐셜을 조사?분석하였다. 농산부산물의 에너지 자원화 기준으로는 메탄생산량을 설정하고, 부산물별 메탄 퍼텐셜을 시험하였으며 측정된 메탄 퍼텐셜을 기초자료로 활용하여 단위면적당 바이오매스 발생량, 바이오가스 생산량 및 비료가치를 조사?분석하였다. 실험적 메탄 퍼텐셜은 농산부산물별로 0.170∼0.354 N㎥ kg<SUP>-1</SUP> VSadded의 값을 보였으며, 그중 파프리카 열매가 가장 높은 메탄 생산 퍼텐셜을 보였으며, 오이 줄기가 가장 낮은 메탄 생산 퍼텐셜을 보였다. 시설 원예에서 기인하는 바이오매스별 메탄생산량은 줄기 부위가 잎이나 열매 부위 보다 낮은 값을 나타내는 경향을 보였다. 시설 재배지의 단위면적당 바이오매스 발생량은 오이 30.5 〉 토마토 28.3 〉 파프리카 21.5 Mg ha<SUP>-1</SUP>순 이었으며, 단위면적당 메탄생산량은 오이 782.5 〉 파프리카 686.8 〉 토마토 645.0 N㎥ ha<SUP>-1</SUP>순 이었다.

Number of crop residues generated at large amount in agriculture can be utilized as substrate in methane production by anaerobic digestion. Greenhouse vegetable crop cultivation that adopting intensive agricultural system require the heating energy during winter season, meanwhile produce waste biomass source for the methane production. The purpose of this study was to investigate the methane production potential of greenhouse vegetable crop residues and to estimate material and energy yield in greenhouse system. Cucumber, tomato, and paprika as greenhouse vegetable crop were used in this study. Fallen fruit, leaf, and stem residues were collected at harvesting period from the farmhouses (Anseong, Gyeonggi, Korea) adopting an intensive greenhouse cultivation system. Also the amount of fallen vegetables and plant residues, and planting density of each vegetable crop were investigated. Chemical properties of vegetable waste biomass were determined, and theoretical methane potentials were calculated using Buswell’ formula from the element analysis data. Also, BMP (Biochemical methane potential) assay was carried out for each vegetable waste biomass in mesophilic temperature (38℃). Theoretical methane potential (Bth) and Ultimate methane potential (Bu) off stem, leaf, and fallen fruit in vegetable residues showed the range of 0.352∼0.485 N㎥ kg<SUP>-1</SUP>VSadded and 0.136∼0.354 N㎥ kg<SUP>-1</SUP>VSadded respectively. The biomass yields of residues of tomato, cucumber, and paprika were 28.3, 30.5, and 21.5 Mg ha<SUP>-1</SUP> respectively. The methane yields of tomato, cucumber, and paprika residues showed 645.0, 782.5, and 686.8 N㎥ ha<SUP>-1</SUP>. Methane yield (N㎥ ha<SUP>-1</SUP>) of crop residue may be highly influenced by biomass yield which is mainly affected by planting density.
