Project long title

Establishment of a 2-stage biotechnological process for the production of (iso)butanol from CO₂ and waste materials.

Project description

By converting CO₂ from industrial waste gas sources into biofuels, an innovative bioprocessing solution is to be developed which on the one hand replaces fossil fuels and on the other fixes CO₂ and thus relieves the environment from two sides.
The chair AVAW is working to raise the potential of the latter for Austria for the production of isobutanol by a combination of industrially generated CO₂ and a co-substrate from waste and residual waste material flows.

Aims of the project

Identifying waste and residual streams that could serve as potential co-substrates for biotechnological CO₂ fixation
Description of the characteristics of the different material streams (in particular waste from food production, agricultural residues, leftovers, dairy waste and separately collected biogenic waste from households)
Survey of the annual volume of these different streams
