Low-Cost Cellulosic Sugars
The lower price of cellulosic sugars from the Glycell™ process also opens up possibilities to replace starch, particularly corn starch, as an input to the 200 corn ethanol plants in the USA. The ability to supplement existing ethanol mills with cellulosic sugar inputs will greatly enhance the environmental benefits of this industry.
Such diverse opportunities are strongly supported by the abundant supply of biomass. There is enough biomass in the world for the production of $7507 billion of cellulosic sugars. In this context, the Glycell™ process represents a real economic breakthrough because it utilizes every portion of biomass input. For example, 94% cellulose (C6) is converted to sugars quickly and in large quantities. Hemi cellulose (C5) is developed as a separate stream of sugars to open up more product opportunities. Lignin comes through the process in a native form, which has higher value usage in chemical world than the current utilization of conventional burning.
Leaf Resources can also revalue our glycerol to make a profit, which brings the final cost of produced sugars to below $50 per tonne and enables the overall process to be competitive with equivalent production.
Other benefits for chemical production and derivative products come directly as a result of using biomass. One of the biggest is that biomass already contains the oxygen necessary to develop a wide range of chemicals and other elements required to develop plastics. By contrast, petro chemical production requires introducing oxygen and other key elements at additional cost.
