Applications of Microbes in Municipal Solid Waste Treatment

The production of municipal solid waste continues to grow every year, which has received great reflection. This daily production without recycling, treatment, and valorization generates environmental crises, health impacts, and economic costs on several municipalities in the world. Currently, microbes in the treatment and recovery processes of municipal solid waste have become a common practice. We will present in this chapter two essential microbial practices (composting and anaerobic digestion) which used microbial inoculation for improved and increased performances.

In the composting process, the application of microbes plays several roles: improvement of humification, secretion of catabolism enzymes, minimize the initial lag time, and reduce the process treatment and odorous emissions. So, the microbial inoculation in the composting way of municipal solid waste provides good compost, increasing soil fertilization, and improving agriculture. In anaerobic digestion technology, the application of microbes in this process has become mandatory. It increases the methane production and hydrolysis rate of municipal solid waste and shortens the start-up time to get the high energy quickly. So, the microbial application for municipal solid waste treatment is an eco-friendly tool, less expensive, and efficient for a zero-waste economy.
