Biofuels - case study


Courtesy of AVA GmbH u. Co. KG

As part of the Kyoto Protocol, the United Nations has called for the introduction of fuels obtained from biomass in order to reduce emissions of greenhouse gases.

The increasing scarcity of worldwide oil reserves associated with the increase in crude oil prices has created the necessity for an increased utilisation of alternative fuel sources. These biofuels will become a fundamental component of our energy supplies in the future. Additionally, biofuels derived from biomass are manufactured from renewable energy sources. They are therefore, where emissions are concerned, in contrast to fossil energy sources, CO2 neutral.

Fuels with bio mass as energy source can be obtained, for example, from:

  • Cereals
  • Cooking or other oils, e.g.
  • Household waste rape seed, sunflower, soy
  • Forestry residues
  • Waste from food processing
  • Tree waste

Biodiesel and Bioethanol belong to the most important biofuels being produced today. The increase of the market share for biofuels and their mixing with regular fuels has been defined in several directives within the EU.

AVA offers technologies from the fields of mixing and drying both for the production of Biodiesel as well as for the production of Bioethanol.

In the production of Biodiesel, AVA dryers are used in order to obtain methanol from the salt created during the process.

However, in the production of Bioethanol both mixing and drying-related applications are required. For this purpose, AVA mixers are used for the mixing of the raw materials. AVA dryers are used for drying the DDGS (Dried Distiller Grains & Solubles) at the end of the production process.
