 note = {As reported in the previous papers1 )2)3)4) of this journal，r aw garbage tossed into ar otating barrel supplying with fermenting bacteria (2 bacteria) was converted to livestock feed or unripend compost after 3-4 hours fermentation treatment. The greenhouse was heated experimentallyby the apparatus shown in Fig.1 and 2. About 4-ton unripend compost was placed in the fermentation diches in the greenhouse with 55 m2 )，in oder to play ar ole of heater. In the same way as mentioned in the previous paper4)，th e greenhouse was started heating by fermentation from early January in 1980. During the period of 3m onths，th e outside air temperature sometimes fell down less than -10'C，bu t under appropriate control of ventilation and water supply，the minimum daily temperature in the greenhouse was 5'C higher than that in outside，a nd the minimum daily temperature inside of the vinyl tunnels covering on the ridge was maintained above O'C，and the soil temperature below 15cm from surface at the middle of the ridge was always maintained above 10'C. The unripend compost put into the heater，r ipened with the time. The compost which was tossed into the ridge reduced in volume of about 80% by ripenning in early spring，a nd it was returned to the farm., Article, 環境科学年報14:25-34(1992)},
