Bioethanol Technology

---

Desmet Ballestra Ethanol offers various Upstreaming Technologies to obtain top quality by-products for the Food and Feed market. Furthermore, our facilities are pure bioenergy facilities where by-products are efficiently used to produce the required process energy. The energy surplus is fed in the plant's power supply system.

Bioethanol

Ethanol derived from crops (bioethanol) is a demonstrably sustainable energy resource that may offer environmental and long-term economic advantages over fossil fuel (gasoline).

It is readily obtained from sugar or starch in crops such as maize and sugarcane


Raw materials

Corn / Maize • Wheat • Rye • Sugar cane / molasses • Sugar beet / molasses • Cassava / Tapioca / Manioc
Spent sulfite liquor • Whey • Lignocellulosic material

Raw materials for bioethanol production are chosen according to their price, and regional availability as well as the local market for by-products.

Thanks to the different dry and wet milling technologies we remain extremely flexible in the manufactoring process of the respective raw materials.

This enables us to meet our customers' needs and provide the best solutions.


Products

Active dry yeast
Instant active dry yeast
Inactive dry yeast (fodder- and nutrition yeast)

Active dry yeast is in the form of tiny, dehydrated granules. The yeast cells are alive but dormant because of the lack of moisture. When mixed with a warm liquid or sugar, the cells once again become active.

This type of yeast is extracted from yeast cream in drum dryers. Since dried yeast has no more fermentative activity, it is mainly used as fodder’s yeast.


Derivates

Ethanol • Carbon dioxide • DDGS ( Distillers’ dried grains with solubles )
Vital Gluten / Gluten • Electrical power • Biogas • Fertiliser

Depending on the type of raw material, up to 65% are directly used for bioethanol production. Alongside, substantial by-products are generated.
