Title
BDF製造副生成物である粗グリセリンがウッドチップ堆肥化に与える効果について
Additional effects of crude glycerol provided as By-product of bio diesel fuels to composting of felled wood tip.
Abstract
Crude glycerin as by-product of bio diesel fuels. For every 1 ton of biodiesel produced, approximately 100kg of glycerol is also created. It is unworthily waste for most small-scale producers due to the large investment in technology necessary for the refining process, although it is possible to refine crude glycerin into a marketable product. In order to reuse it efficiently, we conducted a field trial to confirm an effect of crude glycerol as an accelerator material in composting of felled wood tips. Addition of 1% and 10% of crude glycerol gave high fermentation temperature by 5℃ and 10℃ than that of control for one month. As a result of fertilizer component analysis, crude glycerol treated compost has equivalent components to control. Furthermore, crude glycerol treated compost showed fertilizer efficacy as well as control in germination and growth test of carrot and Komatsu's green.
