BioCoal (Torrefied Pellet) Trading

Graded pellets produced by thermal processing of woody and non-woody biomass.

BioCoal have a higher energy density and more moisture resistant than regular white wood pellets hence more economical to handle and ship as compared to white wood pellets.

As it provides existing coal burning utilities with clean, green, carbon neutral, renewable energy with reduced upfront cost and no lengthy conversion or start-up time hence easy to integrate into existing coal facilities and it can replace coal readily.

Also, The Sulfur and Ash content of BioCoal is significantly low.

Other renewable energy sources such as wind and solar cannot produce power on a consistent and predictable basis, so they cannot be relied upon to meet base-load power needs. However, BioCoal can be used by utilities to meet their base-load power requirements while making it as one of the few forms of renewable energy that can replace coal as a source of base-load power.

BioCoal is a carbon neutral resource and qualify for renewable energy subsidies in many countries.

Our platform covers the trading of the world’s most common standards (including ISO) and non-standard BioCoal products.
