Sludge + worms = compost
Researchers in India have been able to turn solid textile mill sludge into nutrient-rich compost in a 6-month experiment using vermicomposting and manure, according to a report published in the International Journal of Environment and Pollution. The process resulted in increased nitrogen and phosphorous content, both important for plant growth. The pilot project indicates that a shift can be made from disposing of the sludge in landfills or incinerators, which can create environmental hazards, to a safer and more natural alternative.
