Overall, it is a linear process that contain five main stages starting from making holes in container (2m cube) to make a way for the movement of the air and ends after a half year producing compost in the container.
According to the diagram, in the first stage manufacturer makes six holes in the plastic container so that air can easily move to and from the container. Then organic waste is placed into the container about 15 centimeter depth. Food waste is placed firstly followed by grass, and newspaper and all are in 15 centimeter depth. Afterthat, nitrogen and only hot water are added into container that contain organic waste. Moving ahead, manufacturer closes the container with its lid and nitrogen begin to process and due to this process heat comes out form the six air holes, and this process took about six months and after that period garden fertilizers (compost) are ready at the bottom of the container for the consumers.
