Composting is a process in which organic material undergoes biological degradation to a stable end product. The Mill has adopted Surface Composting process for treatment of spent wash by using Pressmud , Spentwash , Microbial Culture , Boiler Ash etc . The standard ratio of Pressmud to Spentwash is 1:2.5 . A fully mechanized aero-tiller machine is used for making good quality compost . The compost cycle is completed within 40 to 45 days and further 10 days are required for curing on maturation yard . The composted material is sold to member farmers at a subsidized rate after testing its parameters in laboratory . The compost yard has capacity to handle 8000 MT Pressmud per cycle . The total compost produced is 25000 MT annually .

Some important properties of the Compost are as follows :

Sr.No Parameters Standard Value Analysis Value
1 Nitrogen, N % 1.5-2.0 1.9
2 Phosphorus, P % 1.5-2.0 1.6
3 Potassium, K % 3.0-3.5 3.2
4 C/N Ratio Below 17 16.00
