I-optimal mixture design and artificial neural network for the sustainable production of vermicompost

Sustainable organic waste management using vermicomposting: a critical review on the prevailing research gaps and opportunities

“…Further, the potential of being good quality compost can be determined by measuring the C/N ratio, CO 2 evolution and Germination Index. 2,5…”

“…According to the results of a comparative study that examined how vermicomposting works as well as the worms' growth in different temperature and moisture ranges, the outcomes demonstrated that a range of moisture between 65–75% was suitable for all temperature ranges for vermicomposting. 5,17…”

“…The physicochemical and biological characteristics of vermicompost is primarily dependent on the nature and type of the substrate(s) used and on the selection of earthworms used in the vermi-conversion. 2,5,13 Hence the selection of substrate(s) is one of the prime design criteria for the efficient vermicomposting process. The elemental composition of the substrate, C/N ratio, pH, particle size and moisture content etc.…”

“…Precisely, it is bio-oxidation and stabilization method which can be accomplished with the symbiotic actions of the earthworms and mesophilic microorganisms. 4,5 Concerning the modes of operation, it can be carried out in bins, pits and heap method and can be operated either in batch or continuous ow system. This process has now widely accepted and being practiced by most of the farmers on their agricultural farms as it is simple to use, recyclable operation, cost-effective and ecologically safe.…”

“…are some of the earthworms were used for the vermicomposting process. 2,5 These earthworms encourage the soil fragmentation and boost the soil aeration by 8-30% in volume.…”
