  范文:As is shown in the flow chart, the process of recycling organic waste to produce compost is really a complex one.

  The whole process can be categorized into five stages. First of all, prepare a plastic container which has four holes for ventilating the air. There is a rule when putting waste into the container, food at the bottom within 15 centimeters high, grass at the middle and newspaper at the top within 15 centimeters high altogether, in order to make a optimum environment for different bacteria reproducing. In the following stage, we can witness nitrogen and water being put into the container. What's worth mentioning is that water is only added in a hot weather. Next, heat the waste and let the bacteria reproduce fastly, with which the organic waste can be decomposed and became garden fertiliser after 6 months. Subsequently, we can carry the compost out and move it to the garden, thus a new recycling can begin.

  In conclusion, using this way to turn the organic waste into garden fertiliser is environmentally friendly. By enlarging the number or volume of the container, we can dispose more waste at the same time.
