Which factor is NOT considered to impact compaction density?

Compaction density in landfills is influenced by several factors that directly affect how waste is compressed and the overall effectiveness of the compaction process. Among these factors, the type of cover, the types of landfill compactors used, and the initial moisture content of the waste are all critical to achieving optimal compaction.

The type of cover can impact how well the waste is maintained and contained, which in turn affects compaction. Various types of covers can provide different levels of air flow, moisture retention, and integrity of the waste pile. Similarly, the type of landfill compactors used determines the force and method of compaction applied to the waste. Different compactors are designed to handle different types of waste and can achieve varying levels of density based on their design and power.

The initial moisture content of the waste is also an important factor. Moisture can influence how waste material settles and compacts, as certain levels of moisture can either facilitate better compaction or create a situation where the waste does not compact effectively.

The number of collection trucks in operation does not have a direct impact on compaction density itself. While having more trucks can potentially increase the rate at which waste is delivered and processed, it does not influence the physical characteristics or properties of the waste that
