MSW (Municipal solid waste) is a severe problem that is rising at an alarming rate in the world’s megacities as a result of overpopulation, urbanization, industrialization, and indiscriminate trash disposal. The municipal solid waste consists primarily of home and business garbage, which comprises biodegradable (paper, food waste, straw, and yard waste), partially biodegradable (wood, and sludge), and non-biodegradable elements (leather, plastics, metals, glass, electronics). Composting is the most broadly applicable waste management technology, especially in India, where 50-60% of MSW (C/N ratio 23) collected is biodegradable.
Many scientific investigations have demonstrated that inoculating MSW composting with microbes can reduce low molecular weight components like aliphatics, proteins, polysaccharides, and so on while increasing the degree of aromatization. This demonstrated that the microorganisms could hasten the composting process. In addition, during composting, combined inoculation with complex microorganisms and lignocellulolytic microorganisms had a noticeable advantage.
