The Consumable/Transformable super asset class can be defined as assets that can be consumed, transformed and have economic value, but do not generate an economic income stream. 

These are your typical physical commodities such as soft commodities, energy, precious metals, and industrial metals. 
You can consume corn, convert it to meat by feeding it into livestock, and convert it in cornflower to bake corn bread or even convert it into an energy commodity such as ethanol. 

A single kernel or even an ear of corn cannot generate a stream of income, and therefore we disqualified it of being a capital asset. This lack of a stream of income makes it impossible to value the asset using net present value. These assets need to be valued based on the supply and demand characteristics of their market. 

The supply and demand calculations need to be made on global rather than regional factors. A similar grade of wheat adjusted for transport, handling cost import/export tax will have a high correlation with other grain of similar grade around the globe. This is another distinction with Capital Assets
