Sugarcane waste biomass torrefaction

NFR BioEnergy LLC specializes in the torrefaction of sugarcane waste biomass, to produce torrefied energy pellets, for the use as direct coal replacement in power plants, residential heating applications and the production of high-grade bio-carbon. The high-grade bio-carbon can be utilized in the production of steel, aluminum, plastics and water filtration as well as the production of high-grade fertilizer. NFR BioEnergy designed and built the first biomass torrefaction facility globally, using sugarcane waste as raw material. A 2 metric ton per hour (18,000 metric tons per annum) torrefaction facility was installed in White Castle, Louisiana and currently a 200,000 metric tons per annum biomass torrefaction facility is being constructed at the same site, while another 8-10 such facilities are planned to be built in the next 5 years. The biomass torrefaction facility is designed to produce high-grade torrefied energy pellets and various high value carbon based materials from sugarcane waste. The energy pellets are hydrophobic, have a 30% higher energy density and a 30% higher bulk density than wood pellets. They have the same energy content as lignite coal and contain lesser amounts of moisture, sulfur, chlorine and ash compared to coal. The pellets can be co-fired in existing coal fired power plants or even replace the use of coal without any modification or capital expense to the existing power plant. 3-4 metric tons of sugar cane waste with a moisture content of about 50% are used to produce 1 metric ton of torrefied energy pellets. Currently the sugar industry in the state of Louisiana produces 6-7 million metric tons of sugarcane waste annually. The majority of this waste is currently incinerated in the sugar mill boilers. The excess sugarcane waste that can’t be burned in the sugar mill boilers because of environmental restrictions, is stored in huge piles and left to slowly bio-degrade.
 
The sugarcane waste, left behind in the sugar cane fields, is usually burned in the fields, creating a huge negative environmental impact. NFR BioEnergy’s mission is to convert all available waste sugarcane biomass into torrefied energy pellets and other high quality carbon based materials, while increasing the yield of sugar and closing the carbon cycle for the farming of sugar cane. The project’s Phase 1 “Mini-Me” has created 14 permanent jobs with the potential to produce 18,000 tons of torrefied energy pellets per annum, utilizing annually 60,000-70,000 metric tons of sugarcane waste. Phase 2 and Phase 3 De-trashing and Maxi-Me create 48 permanent jobs with the potential to produce 200,000 metric tons of torrefied energy pellets annually, replacing the use of 200,000 tons of coal annually and utilizing 600,000-800,000 metric tons of sugarcane waste each year. Phase 4 will create an additional 400 permanent jobs with the potential to produce 1.6 million metric tons of torrefied energy pellets annually utilizing 6-7 million tons of sugarcane waste.
