Why is the C/N ratio important in composting?

• It helps in identifying the best waste for combustion

• It determines the microbial activity during decomposition

• It measures the amount of ash content in waste

• It classifies waste as hazardous or non-hazardous

What is the main purpose of Toxicity Characteristic Leaching Procedure (TCLP)?

• To measure the biodegradability of waste

• To determine if waste is hazardous based on leaching potential

• To analyze moisture and volatile content in waste

• To calculate the calorific value of waste

In biological analysis, which waste component produces the highest methane yield during anaerobic degradation?
