Which of the following statements is/are TRUE for the aerobic composting of sewage sludge?

Bulking agent is added during the composting process to reduce the porosity of the solid mixture
Leachate can be generated during composting
Actinomycetes are involved in the process
In-vessel composting systems cannot be operated in the plug-flow mode

Correct answer: Actinomycetes are involved in the process

Solution

Actinomycetes are a group of bacteria that play a crucial role in the decomposition of organic matter during aerobic composting, helping to break down complex compounds and contributing to the overall microbial activity essential for effective composting.
