NDDB completed the patent registration process for three processes: I) A System and Method for Dung Quality Testing, II) A System and Method for Bio Slurry Quality Testing and III) Process to produce granular organic fertilizer extracted from digested cattle dung. The patented process presents a potential scalable solution for ensuring quality control of dung and slurry procurement for manure management projects, quality-based fair and transparent pricing mechanism for dung and slurry payment to dairy farmers, organic fertilizer production, aligning with sustainable agriculture practices. The field testing will ensure quality control and the scalability of this technology. Further, a method to produce granular organic fertilizer from cattle dung, without the use of any binders improves the quality of the fertilizer while reducing the use of external materials.
NDDB has developed a dairy Effluent Treatment Plant (ETP) sludge based organic fertiliser named as Phosphate Rich Organic Manure(PROM), aiming to provide a nutrient-rich alternative to phosphatic fertilizers. Preliminary analyses of sludge from multiple dairy plants revealed high nutrient content, prompting a scientific field experiment to evaluate its impact on pearl millet cultivation. Different formulations, including an enriched version with 8% P2O5 and with 12% P2O5, were tested against biogas slurry-based PROM and conventional fertilizers. The study focused on plant growth, nutrient uptake, and soil health, showing promising results in crop yield and soil fertility improvement.
A ETP sludge based organic fertiliser product has been developed for Banas Dairy. An exclusive ETP slurry based organic fertiliser plant is also being established in Vidya Dairy.
NDDB conceptualized and developed the idea of methane pyrolysis for hydrogen production from dung based CBG. In collaboration with Sustain Plus and Banas Dairy India’s trial plant is established in Banas Bio-CNG plant. Using methane pyrolysis, the CBG produced at Banas Dairy is being converted into Hydrogen. As the trials succeed with consistency, the hydrogen produced can be blended with CBG and dispensed through existing infrastructure enhancing fuel performance. In the process of pyrolysis, carbon black will also be produced which is a valuable by-product that can be supplied to industries such as rubber, tyres, and coatings. Since the carbon black is produced from dung, its potential use in agriculture too is being explored.
