The game-changing final stage of CBG bio fuel — shredding Napier grass and biomass to a fine 5–10 mm feedstock that decays in 45 days and yields 2.5× more gas.
Particle size is the single biggest lever on gas yield in this sector. Big 16–20 mm Napier cuttings take up to 6 months for micro-organisms to decay inside the digester. Shred the same material down to 5 mm and it decays completely within 45 days — and produces 2.5× more gas output from the same feedstock.
That is why a high-output fine shredder is the most important machine in a CBG, Gobar Gas or Bio Gas plant's raw-material line — it converts more of your biomass into gas, faster.
Even today, no off-the-shelf machine — in India or globally — fully meets every customer's CBG requirement at 100% performance. What makes the difference is design experience.
Thumba has designed, manufactured and supplied chipping and shredding machines since 2005 — over 20 years — across dairy, agriculture bio-composting and industrial bio-fuel briquette manufacturing. That depth lets us develop a high-output fine shredder tuned to your input material and 5–10 mm target size.

Because each machine is engineered to the customer's own input material and plant capacity, pricing is quoted per project rather than as a fixed catalogue price.
Share your input material, target shred size and daily tonnage — we'll design and quote a high-output fine shredding machine, delivered within 90 days.
