3 / / 1390 / Introduction: Due to the unfavorable smell of the accumulated sugar beet wastes in the
factory and its mixture with the lime wastes, it is costly and uneconomic to dispose this
mixture. This research has been performed to investigate the possibility of producing
compost and vermicompost from the waste in sugar beet factory in Qazvin.
Materials and Methods: In order to produce compost, sugar beet wastes were collected.
Temperature, moisture and aeration were controlled during production period. The quality of
compost was examined by carrying out a series of quality control tests concerned with
ripening degree.
Results: The initial results indicated an initial increase in temperature to over 60oC due to
intensive activity of microorganisms. The temperature decreased gradually and reached the
environmental temperature after two months. In order to investigate and control the quality
of the produced compost, ripening degree of compost was calculated. Comparing the
experimental results with the standard indices of ripening degree showed that the product is
suitable in terms of temperature variation, cress, and percentage of Ammonium-Nitrate.
Conclusion: Apart from the above findings, the produced vermicompost was suitable in
terms of ripening degree. The produced vermicompost was superior to the compost produced
from sugar beet wastes in terms of chemical characteristics, i.e., Phosphor in vermicompost
increased 3 times as compared to compost while saltiness decreased by 50%. Zinc and
Nitrogen were also increased.
