In a fully mechanised composting plant, involves A. Mechanized receipt B. Mechanized segregation C. Mechanized pulverising of refuse D. All of these

The correct answer is D. All of these.

In a fully mechanized composting plant, the following steps are involved:

1. Mechanized receipt: The refuse is received at the plant and unloaded from the trucks.
2. Mechanized segregation: The refuse is segregated into different types of materials, such as paper, cardboard, food waste, and yard waste.
3. Mechanized pulverising of refuse: The refuse is pulverized into small pieces.
4. Mechanized mixing of refuse: The refuse is mixed with other materials, such as wood chips, sawdust, and manure.
5. Mechanized aeration of refuse: The refuse is aerated to provide oxygen for the composting process.
6. Mechanized turning of refuse: The refuse is turned to ensure that it composts evenly.
7. Mechanized monitoring of refuse: The refuse is monitored to ensure that the composting process is proceeding correctly.
8. Mechanized removal of finished compost: The finished compost is removed from the plant and sold or used on-site.

Mechanized receipt, segregation, pulverising, mixing, aeration, turning, monitoring, and removal are all essential steps in the composting process. By mechanizing these steps, a fully mechanized composting plant can produce high-quality compost in a timely and efficient manner.
