Green products from distiller’s waste

Distiller’s waste (‘drank’ in Swedish) is obtained from the waste stream of bioethanol production. Today, distiller’s waste is generally added to animal feed or used to produce biogas. However, in light of projected increases in global bioethanol production, novel biotechnological applications for distiller’s waste would add value to the process – making it an economically and environmentally sound alternative to fossil fuels.


Within the research programme MicroDrivE, there are several projects that focus on such novel applications of distiller’s waste. 


  1. New “green” products from bio-ethanol production.
  2. Distiller’s waste as a substrate for chitosan production.
  3. Development of starter cultures for stabilisation of distiller’s waste.
