Fine Shredding & Screening Machines

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.

High-output fine shredding machine for CBG bio fuel biomass feedstock

Why Fine Shredding Is the Game-Changer

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.
