CARBAFIN is a collaborative research project, which started in January 2018 and will last until December 2021. It is co-financed by the European Union with a funding of 5.3 million Euros. The EU-consortium consists of eight members coming from five different countries. A phosphorylase-based platform for the sustainable production of functional glucosides from sucrose is being developed. The aim is to generate a new value chain for the use of surplus sugar beet biomass in the EU by the separate conversion of glucose and fructose into value-adding products on an industrial scale.

The Working Group Sustainable Construction and the Institute of Business Economics and Industrial Sociology at Graz University of Technology are investigating the economic feasibility of the developed methods. This work package is a cross-departmental activity, which interacts strongly with all other work packages and ensures that considerations of LCA and technical-economic analysis are taken into account in every phase of development and route selection, and generally in all process decisions. Thus, the processes are designed from the very beginning and optimized from an economic point of view

By identifying ecological hot spots, cost saving potentials and optimization potentials for process improvements are pointed out. For this purpose, the costs in each sub-process are analyzed and examined for optimization potentials.  In addition, the life cycle costs are presented in order to identify future optimization potential. In addition, an economic evaluation of the processes is carried out in order to demonstrate the advantages of the project quantitatively. The evaluation results serve as a guideline for improvements during the process development and as feedback for the technicians. Finally, a combined evaluation of the optimized processes as best practice examples for bio-based chemical production will be performed. An overview of the achievements of the research group and the institute:

  1. development of a life cycle cost model for biochemical processes
  2. hot spot analysis and development of an improvement plan with recommendations for process optimization
  3. development of a model for the evaluation of processes
  4. economic evaluation of biochemical processes
