The red worm Eisenia foetida is a nondiscrimination eating machine. Long been raised for fishing worms this critter has an important new role in India’s sustainable waste efforts.
Sludge from the textiles industry is usually difficult to dispose of. Landfill and incineration are not viable options given environmental concerns and expense. India’s industrial complex is under pressure to find a sustainable and cost-effective alternative to disposal of industrial sludge.
Vermicomposting is turning solid textile mill sludge spiked with urine-free cow and horse dung, collected from local farms into rich dark soil fertilizer after just 180 days.
Nutrient benefits of worm produced soil
Earthworms lower the pH of the alkaline sludge, free up mineral ions, including potassium, decrease the ratio of carbon to nitrogen of the material, and boost the amount of nitrogen and phosphorus available for plant growth within a matter of weeks.
