The pictures give information about the process of recycling organic waste to generate garden fertilizer.
Overall, there are five steps to produce fertilizer, starting from preparing compost media until generating garden fertilizer.
First of all, a plastic container with the size of 2m3 is prepared and hollowed out on four sides of the container in order to release air. After that, different kinds of organic waste are put into the container, such as newspaper, grass, and food until reach a depth of around 15 cm. In the next step, several amounts of nitrogen are added to the mixture together with hot water in order to increase the temperature inside the container.
In the last process, the container which contains the mixture of organic waste and liquid nitrogen is closed to prevent outside air enters the container, while releasing the inside air. Finally, the container is preserved for around 6 months until garden compost is produced.
