As we gather new comparative data, the range of numbers may change according to the feedstock.
With each different feedstok processing, the co-products may have different environmental impacts as well.
Ben B. is great at finding reference material and many of you that are building community projects can also use references in your presentation to the public and to the regulators, it is of utmost importance because it shows 94, 77 and 11 Kg of gasses to Greenhouse effect.
Incredible.
This is an enormous advantage for our proposal for cattails; and corn ethanol cash helps us also. Keep up the good work, Peggy and Ben
