The diagram illustrates the process of producing compost from organic waste, which can later be used as fertilizer in gardens.
Overall, the procedure is relatively simple and involves five stages, beginning with the preparation of a container and ending with the production of compost after six months.
At the first stage, a plastic container with a capacity of two cubic meters is prepared. Air holes are made on the sides of the container to allow ventilation. Then, layers of organic waste, such as food scraps, grass, and pieces of newspaper, are added. Each layer should be around 15 centimetres in height.
In the third step, nitrogen and hot water are poured into the container to speed up the decomposition process. The mixture is then left for a period of six months. During this time, air circulation through the holes ensures that the organic matter breaks down properly.
Finally, after half a year, the waste is converted into compost. This final product is nutrient-rich and can be applied directly to the soil to improve plant growth in gardens.
