Answer:
Industrial sludges and some well-digested sludges might not compost well because they can contain high levels of heavy metals, toxic chemicals, and pathogens. These contaminants can inhibit microbial activity necessary for composting, making the process inefficient or even hazardous. Additionally, some sludges have low organic content or poor carbon-to-nitrogen ratios, further hindering effective composting.
