Bioethanolproduktion seit 2005

Die Bioethanolproduktion ist ein bedeutender Wirtschaftsfaktor: Die deutschen Hersteller verarbeiten in erster Linie Rohstoffe aus ihrer Region und bieten den heimischen Landwirten so eine zusätzliche Absatzmöglichkeit für ihre Produkte. Darüber hinaus schafft die deutsche Bioethanolwirtschaft wichtige Arbeitsplätze im strukturschwachen ländlichen Raum.

Bioethanolwerke in Deutschland:

CropEnergies Bioethanol GmbH (Unternehmen der CropEnergies AG) in Zeitz, Sachsen-Anhalt. Produktionskapazität ca. 285.000 Tonnen/Jahr

Nordzucker AG in Stadt Wanzleben-Börde, Sachsen-Anhalt. Produktionskapazität ca. 100.000 Tonnen/Jahr

Sachsenmilch Leppersdorf GmbH in Leppersdorf, Sachsen. Technischer Alkohol und Bioethanol aus Molke-Restprodukt. Produktionskapazität ca. 8.000 Tonnen/Jahr

Suiker Unie GmbH & Co. KG in Anklam, Mecklenburg-Vorpommern. Produktionskapazität ca. 55.000 Tonnen/Jahr

Verbio Ethanol Schwedt GmbH & Co KG (Unternehmen der Verbio AG) in Schwedt, Brandenburg. Produktionskapazität ca. 170.000 Tonnen/Jahr

Verbio Ethanol Zörbig GmbH & Co KG (Unternehmen der Verbio AG) in Zörbig, Sachsen-Anhalt. Produktionskapazität ca. 60.000 Tonnen/Jahr (bis 2018: 90.000 Tonnen/Jahr)

Demonstrationsanlage:
Clariant Produkte (Deutschland) GmbH
in Straubing, Bayern. 1.000 Tonnen/Jahr Zellulose-Ethanol mit dem "Sunliquid" -Verfahren aus Weizen- und Maisstroh
