Outline of Final Research Achievements

Developing plant factory industry will require disposal of its agricultural organic wastes. The waste disposal cost was estimated to account for about 10% of their gross profit at one cycle in the case of 100 m2 scale of greenhouse horticulture. Component analysis was conducted to utilize agricultural wastes. The wastes were high in minerals including phosphorus and carotenoids such as lutein, indicating that the wastes could be used as one of carotenoids sources for a food and/or feed preservative and fertilizer after carotenoids extraction. Carbon nitrogen ratios in the wastes were generally low, in other words, they were high in proteins. Ammonia inhibition should be in mind in bio-chemical transformations such as methane fermentation.
