Since the use of microorganisms to convert medicinal waste residues into growth stimulants is both eco-friendly and straightforward, it has the potential to be implemented in pharmaceutical manufacturing facilities. The purpose of this research was to determine the most effective strategy for recycling unused medicinal waste into plant growth-promoting substrates. The obtained results of the experiments indicated that the best method for processing medicinal waste into humus is to use the CT4 formula with a 90:10 ratio of medicinal waste to pig solid waste. The ratio of carbon and nitrogen in humus (C/N, <
12,) and the concentrations of humic acid (4.25%), organic carbon (11.9%), easily digestible phosphorus (0.61%), and total nitrogen (1.11%) ensure that the organic fertilizer is of high quality. The concentration of IAA activity reaches 95 ppm.
