Composting the solid organic wastes happens solely with the microbial actions form the initial step till the final step. So, let us have a look in detail, the action of microbes and other parameters in the industrial composters.
How the composters work?
As we know, composters are basically large bins with pre-defined parameters. They help the process of composting to happen in a rapid pace. This is accomplished due to the salient features available in a composter. For instance, efficient composters like VNS Enviro’s “Bio chest” have shredders to tear down the waste feed and make them into smaller components. It also has filters and Aeration apparatus that drives the process and produces high quality compost.
The microbes that act in the composting process
The composting process involves three phases, and uses diverse microflora such as mesophilic and thermophilic bacteria, fungi and Actinomycetes eventually converting organic waste to humus. During the first phase there is an increase in carbon dioxide production along with the temperature. The substrate is reduced due to the degradation of sugar and proteins by the action of mesophilic organisms. The second phase leads to an increase of the temperature in the compost piles to approximately 20 °C above ambient Temperature and the Mesophiles are replaced by thermophiles. Large numbers of pathogenic microbes are killed during this time. The third phase begins with the decrease of temperature of the compost pile.
To conclude, apart from the action of the microbes, the quality of the humus or the compost in influenced by diverse factors like temperature, pH and moisture content. On the whole, this process sets its main focus on building a sustainable ecosystem by being a major force in solid waste management cadre.
