Second generation ethanol

Stroh ist eine mögliche Rohstoffquelle für 2G Bioethanol

Cellulosic ethanol

Second generation (2G) ethanol draws on previously unused (ligno-) cellulosic plant parts, such as straw or corn cobs.

The commercial production of 2G ethanol is still in its beginning. Legal framework, especially in the US and Europe, has led to intensive research and development of 2G processes. Demonstration plants are operated to prove the feasibility of these methods on a larger scale. Worldwide a number of industrial facilities have commenced operations meanwhile.

The core area of the new developments is the preparation of the raw material. The support structure of the plant, lignocellulose, must be broken down in order to then make the cellulose accessible to saccharification.

From the resulting hydrolysate bioethanol is produced by fermentation, distillation and dehydration, as in the classical process. For these steps modified first generation technology is used.
