Vega Biofuels, Inc. announced that it has expanded its manufacturing capabilities to include multiple sizes of its bio-coal product to meet recent demand. The generation 4 machine has been used to produce a bio-coal product that looks very similar to a piece of traditional Powder River Basin Coal and is approximately the size of a golf ball.  As a result of the demand for other applications, Vega Biofuels has developed both a powder version and a pellet version of its bio-coal product.
