The diagram describes the process of converting organic waste into fertilizer.
Overall, there are five steps in the process, beginning with preparing a plastic bottles to contain and concluding with collecting compost for the garden.
In the first step, after the plastic container 2 cubic meters in volume is prepared, it is perforated some hole side to allow free air flow. Then, the shredded waste is placed inside the compost bin. Wastes food lies at the bottom of the container and have 15cm in height. On its top grass which is also 15cm in thickness. Finally, piece of newspaper are spread over.
In the next step, nitrogen is poured in and water is needed only when it is hot. At that moment, the top is sealed, these organic wastes start exothermic reaction, energy generated in the forms of heat being released through the holes of tank. After 6 months of fermentation, all the wastes are converted into the fertilizer that can be used in gardens.
