The diagram shows how to recycle organic waste to produce garden fertiliser.
The operation goes in four stages according to the information shown in the diagram. First, we can see there is a plastic container with 2 cubic metres in capacity and four air inlets on walls allowing air to penetrate. Then, the waste is put into this plastic container, such as food, grass and newspapers when food and grass take 15cm each. In the third step, nitrogen and hot water (cold water is not permitted) are injected in. In the fourth container, we can see the heat coming from the bottom. After 6 months, the stored compost—green fertiliser—is formed and ready to go for gardening.
In short, the scheme of organic fertiliser production has been described above clearly.
