A novel low-tech mobile pyrolysis blanket has been developed for effective on-site conversion of woody biomass in slash piles to biochar. Slash is constantly cut and piled as part of forest management efforts, and often left in the forest to degrade, or is burned to decrease fire risk and insect outbreaks. Primary forest residues are the key amendment to soil fertilization. Slash represents a sizable and sustainable feedstock for the application of biochar as a soil amendment. Integral to the utilization of this material is the development of inexpensive technologies which can produce biochar. Demonstrated here is a laminated blanket material that integrates multiple functionalities in order to mimic traditional biochar kilns. This system is flexible and portable making it easy to work with and suited to reach the dispersed slash piles. The functionality of this technology, namely producing biochar and controlling the temperature inside the blanket with the altered inlet/outlet system, is demonstrated on a pile of dimensional lumber. The biochar was analyzed and the percentage of biomass converted was graphed demonstrating the blankets functionalities and results.
