Experiment on disposal of spent wash (Vinasse) by composting with press mud cake (PMC) through
microbial consortium treatment by pit and windrow system was conducted at Dnyaneshwar Sahkari
Sakhar Karkhana (S.S.K.), Bhende, district Ahamednagar of Maharashtra, India. The compost prepared
by windrow and pit methods from PMC and spent wash using microbial culture within 45 days ranged
C: N ratio from 10.19:1 to 13.88:1 and 14.32:1 to 22.34:1, respectively. This indicated the effectiveness
of microbial decomposing culture on production of good quality compost in a short period of time.
Both the methods gave the higher nutritive manurial values after completion of process of
composting. The compost obtained in various treatments by windrow method contained 1.52-3.7 % N,
0.9-3.54 % P2O5, 1.95-3.45 % K2O, and had pH range from 7.02-7.82. Similarly the compost obtained
in various treatments by pit method contained 1.34-2.85 % N, 0.30-0.72 % P2O5, 2.20-4.72 % K2O, and
had pH range from 7.40-8.16. Microbial consortium used in the present investigation included
phosphate solubilizing fungi and Burkholderia species isolated from the sugarcane and sugar beet
Due to microbial process and aeration, both BOD and COD values were reduced substantially.
Microbial population was higher in compost from windrow system as compared to in compost from pit
method. On the basis of result obtained, it was concluded that windrow system of composting was
better than pit method. Effluent utilization which poses environmental problem can be safely and
effectively solved by this technology through microbial consortium treatment.
