The provided diagram illustrates how fertilizer can be produced from organic waste at home.
Overall, this process comprises five steps, divided into two main stages: pre-processing and composting.
Pre-processing consists of three steps, with the first one being the preparation of a plastic container. This container is 2 cubic meters in volume and has multiple holes on its body that enable airflow. Moving on to the second step, food, grass, and newspaper are respectively layered into 15cm-tall piles in the container. Nitrogen and hot water are also later added to catalyze the waste decomposition.
Composting includes two steps. First, the mouth of the container is sealed, leaving the waste inside to decay. The heat produced during this process could escape through the holes on the container’s body. After six months, the waste mix turns into fertilizer and is then ready to enrich gardens. The container itself could be utilized to hold soil on top of the fertilizer layer, making room for a garden inside.
The sketched diagrams depict how compost is made from recycled organic waste. Overall, there are five stages in this process, beginning with the setting up of a plastic container and culminating with using the organic fertilizer during gardening.
Firstly, a plastic container with a capacity of 2 cubic meters is set up as the vessel in which daily organic waste would be turned into compost. To begin, four air holes are cut along the sides of the container, allowing free air movement. Following this, organic waste is disposed into this container, before being covered upon with 15 centimeter-thick layers of food, grass, and then newspaper respectively. Nitrogen and water (hot water exclusively) are then added to the mix.
In the fourth stage, the plastic container is sealed, heated, and kept heated for 6 months. This time window allows the waste to ferment thoroughly, thus turning it into compost at the end of this half-a-year time period. In the plastic container, there is now organic fertilizer, ready to be used in gardening.
