The North Carolina Division of Pollution Prevention and Environmental Assistance has announced a new online commodity trading Website for organic materials to help expand the development of the biomass economy in North Carolina, US. NC BiomassTrader is a free online waste exchange for surplus and waste biomass materials such as vegetable oil, restaurant grease, wood waste, manures, food waste, forest products and byproducts, and agricultural products and byproducts. The trading site is available to individuals, organizations and businesses. Although NC BiomassTrader is not a sales tool for commercial ventures to advertise products, it is a platform for trading valuable materials that may otherwise be discarded, buried in landfills, discharged to sewers or otherwise disposed. The Web site is a spin-off from the free commodity trading site NC WasteTrader and is a joint project of the NC Division of Pollution Prevention and Environmental Assistance and the State Energy Office.
