The image depicts a six-step process for converting food waste into clean energy and fertilizer. Step 1: 1.2 million tons of food waste are removed from the earth. Step 2: Uneaten food is converted to 440,000 tons of wet "food pellets". Step 3: 99,000 diesel power plants are replaced with clean energy generators. Step 4: After about 4 years, food waste is completely converted to fertilizer. Step 5: Fertilizer, now in final form as 120,000 tons of "digestate", pours out. Step 6: Organic fuel and nutrient rich waste is pumped into compost bed.
Given the complexity of the image, the above description may not be entirely accurate.

The diagram illustrate the way of uranium is utlilized for nuclear power.
Overall, there are six steps until uranium is ready for produce new clear power and it takes some certain times until process is completed.
Firstly, uranium is minded from the earth by using special machinle. After that, uranium ore is converted and enriched to make U-235 fuel pellets. In third step, U-235 fuel powers generators are used
to make electricity. After approximately four years use, fuel becomes less useful and is removed. However some spent fuel still can be re-processed and re-used to make electricity so the process of step 3 is repeated. Finally, spent fuel that cannot be reprocessed is stored in contaniners and buried.
