Importance of Pretreatment

Biomass always requires a type of sizing and drying to become usableBiomass is a difficult energy source with many logistical challenges from harvesting, handling, shipping, to storage, feeding and combustion.  Biomass comes in many forms, shapes, sizes and is almost all wet and bulky to handle.  Conversion into a commodity, renewable, sustainable product which is fungible and economically transportable in large quantities is our goal!


Torrefaction Advantages

Torrefaction transforms biomass into an easily usable fuelBiomass pretreatment by means of our patented torrefaction technology converts most any type of biomass into a renewable, sustainable, carbon neutral coal substitute – GreenCoal™ torrefied biomass.   When used in electrical generation facilities this product reduce NOx, SOx, and CO2 emissions and allows the facility to meet RPS standards without the need for capital investment.

Torrefaction Technology

Torrefaction is a thermo chemical process Operating at temperatures between 250 and 300 degrees C. in an oxygen deficient environment, our patented torrefaction technology radically transforms the biomass by removing water and various volatile organic compounds (VOC) while dramatically increasing the fuel’s heat content and bulk density.  The fuel’s performance characteristics include improved grind ability and it has become hydrophobic.

Markets for Torrefied Biomass

Electrical, Home, and Industrial MarketsThere exist three general markets for GreenCoaltm torrefied biomass.  These are the electrical generation market, the home heating market, and the industrial market.   In the electrical and industrial market the product can be used to directly displace coal or used in co-firing situations w/o the need for capital investment.  In the home heating market the product can be used instead of wood pellets.


Green Jobs, Economic Growth

GreenCoal™ torrefied biomass technology and its potential for Economic Development When a torrefaction facility utilizing our proprietary torrefaction technology is located in an area with an abundance of under-utilized biomass, living wage Green Jobs will be created both inside the facility and with biomass feedstock providers.  This will foster economic development and growth in both the forestry and agricultural communities


Flow Diagram for the Torrefaction Facility

Torretaction is a mild pyrolysis (roasting) process carried out in the absence of oxygen which renders the biomass, including feedstocks such as forestry residues, waste wood and switchgrass, into a dry, energy dense, easily grind-able, hydrophobic, and cleaner burning solid fuel.
