Waste in, three streams out
Cellulosic ethanol has never failed for lack of feedstock. It has failed on process economics: slow hydrolysis, dilute sugar liquors, inhibitory by-products, and capital costs that only make sense at enormous scale. This route attacks all four.
Laboratory results
Per dry ton of feedstock
The process decomposes the structure of lignocellulosic material, extracts the lignin as a high-energy fuel, and converts both cellulose and hemicellulose into fermentable sugars with practically no detrimental by-products.
| Measure | Corncob | Sugar cane bagasse |
|---|---|---|
| Cellulose conversion to glucose | above 95% | above 90% |
| Hemicellulose conversion | about 99% | about 99% |
| Glucose yield | more than 0.51 ton | more than 0.48 ton |
| Pentose yield (mainly xylose) | about 0.50 ton | about 0.37 ton |
| Lignin produced | about 150 lb | about 400 lb |
| Ethanol yield | 138 gallons (523 L) | 117 gallons (443 L) |
| Electric potential from lignin | 271 KWH | 696 KWH |
Electric potential assumes 60% efficiency for thermal energy conversion.
Why it is different
Four constraints, addressed at once
Reaction time
The process controls the speed of the hydrolysis reaction, bringing reactor residence time under four hours where conventional approaches take days. Residence time is reactor volume, and reactor volume is capital.
Liquor concentration
Final glucose concentration can be controlled without additional energy consumption, while still yielding a high concentration of pentose liquor. The liquors come out ready for fermentation, with no intervening concentration step.
By-products
Inhibitory by-products are why many pretreatment routes need a detoxification stage before fermentation. This route largely avoids producing them.
Operating cost
Solvent and cellulolytic enzymes are recovered and recycled, energy consumption is low, and so is the investment in machinery and equipment. Together those change the minimum viable plant size, which is what has kept this industry out of reach for operators who already sit on the feedstock.
Deployment
Where the residue already sits
Corncob, corn stover, rice straw, sugarcane bagasse and other cellulosic agricultural wastes. The deployment case is strongest where lignocellulosic residue already accumulates in volume at a fixed location: sugar mills, corn processing, rice production. No collection network to build, no feedstock to buy.
Stated plainly: this is demonstration-stage technology. The figures above are laboratory scale. The gap between laboratory yield and plant yield is exactly where cellulosic ethanol projects have historically failed, and closing it is what the demonstration plant is for. We are seeking a partner to install one and complete the development process.
