What stages are involved in the composting process?

The composting process involves several critical stages that work together to transform organic waste into valuable compost. The correct choice highlights three integral phases: preprocessing, decomposition, and stabilization.

In the preprocessing stage, organic materials such as kitchen scraps, yard waste, and other biodegradable inputs are collected and prepared for composting. This may involve shredding or mixing materials to create a more uniform and manageable composition that facilitates the subsequent stages.

Decomposition is the core phase where microorganisms, fungi, and other decomposers break down the organic matter. This stage is characterized by the activity of bacteria that thrive in aerobic conditions, leading to the conversion of organic materials into simpler compounds. It is during this stage that heat is generated, which aids in killing pathogens and weed seeds, resulting in a safer final product.

Finally, the stabilization phase occurs as the organic matter reaches a more stable state. This involves the maturation of the compost, reducing its temperature and allowing the material to age. The end result is a nutrient-rich soil amendment that can be applied to gardens and landscapes, completing the composting cycle.

The other options, while mentioning various processes, do not accurately reflect the stages specifically involved in composting. They refer to different waste management or processing methods that do not encompass the
