Abstract: Herbal solid waste being generated by pharmaceutical industry has been mixed with cow manure and thereafter composted by windrow method. Physico-chemical parameters were monitored before and after 60 days of composting process. pH and EC values of 7.49 and 2.97 respectively were found within the acceptable limit in the finished compost whereas C: N ratio decreased from 26.10 to 10.42 and approximately 42.39 % of the total C was lost during the whole period of composting. Moreover, considerable amount of macro and micro nutrients were found and heavy metals were detected within the permissible limit. Hygienization was determined by disappearance of faecal coliforms and Salmonella after composting process. Total number of faecal coliforms significantly decreased from 2.1x109 to 1.5x102 while Salmonella was eliminated and not found in the finished product. Marked increase in the seed germination (%G) and germination index (GI) values at the final stage has been found while phytotoxicity was observed only in the initial stage of composting.
