After vermicomposting in the reactor, the parameters of pH, fecal coliform, phosphorus, organic matter, and C/N decreased whereas the parameters of carbon, nitrogen, nitrate, ammonia nitrate, and EC increased, slightly. The results show that vermicomposting in the smart reactor took 50% less time and 30% more worm growth rate to produce the same quality as in a container. We analyzed the physicochemical, bacterial, and microstructural of produced vermicompost and growth rate of worms in a substrate of 70% sewage sludge, 20% cow manure, and 10% sugarcane bagasse in a container and the smart reactor. In this reactor design, all aspects of growth and reproduction of Eisenia Fetida worms, such as aeration, temperature, light, and moisture, were considered. This study aims to design a smart closed reactor of vermicomposting to convert sewage sludge and any organic waste to high-quality vermicompost.
