Biochar is the solid product resulting from the heating of biomass at high temperatures in an oxygen-deprived environment. Biochar serves as a soil amendment product, and its widespread implementation may improve agricultural yields in areas with high forest wastes and high carbon emissions due to its carbon sequestration properties. This project uses slow pyrolysis at 800 ̊C to convert 100,000 dry metric tons of southern pine wood waste annually into biochar. Because this plant yields green hydrogen as a side product, this plant is located near the Gulf Coast Hydrogen pipeline in Southern Louisiana, an area with 6.35 million metric tons of wood waste. Following a number of separation techniques, the annual production rates for this project are 19,200 metric tons of biochar 3906 metric and H2 .

The economic analysis for this project predicted a -$143,845,300 net present value (NPV), a -15.18% return of investment (ROI), and a negative internal rate of return (IRR). Although the project is currently not financially sustainable, there are a number of suggestions in this report for deriving additional economic value, such as designing a singular pyrolysis unit large enough for our feed requirement, rather than using six parallel units.
