High Value Silicon Carbide from Agricultural Waste

Research scientists at the Naval Research Laboratory (NRL) have shown that using high temperatures or microwaves many agricultural wastes can be transformed into high value silicon carbide (SiC) consisting of nanostructures and nanorods in various polytypes. Billions of pounds of agricultural waste are generated every year world-wide. Rice and wheat husks, corn stalks, cobs, sorghum leaves, peanut shells and other residues are considered to have no value and are plowed into fields or incinerated.
