Three students – Vinod Garg, Renuka Gupta and Priya Kaushik – from Guru Jambheshwar University of Science and Technology, Haryana, have found solutions to treat sludge from the textile industry.
They tested a new recipe for vermi-composting of solid textile mill sludge spiked with urine-free cow and horse dung collected from local farms, using E. foetida earthworm. The composting process changed the physical and chemical properties of the test mixtures significantly.
