The heat treatment partially degrades the hemicellulose in the biomass, resulting in a hydrophobic, dense, dark-colored pellet that closely resembles coal in handling characteristics.
The most significant advantage of black pellets over white wood pellets is their hydrophobicity — the water-resistant surface means they can be stored in open-air conditions or transported without moisture uptake, which is a critical limitation of conventional wood pellets. This allows coal power plants to handle black pellets using their existing coal infrastructure — conveyors, crushers, silos, and burners — with minimal modifications.
Urja Mitra’s black pellet supply chain is designed specifically for power utilities and large industrial consumers seeking to increase their biomass co-firing ratio in compliance with India’s Renewable Purchase Obligation (RPO) targets. Our aggregator model ensures consistent supply volumes for long-term supply agreements with power plants.
With calorific values in the range of 4,800–5,200 kcal/kg, black pellets offer energy density approaching thermal coal (5,000–6,000 kcal/kg), making them the most direct and cost-effective coal substitute available in the biomass fuel spectrum today.
