Upgrading of Renewable Domestic Raw Materials to Value-added Bulk and Fine Chemicals for a Biobased Economy: Technology Development, Systems Integration and Environmental Impact Assessment
In this project, a new biorefinery concept is developed in which forest residue (GROT) and micro-algae are converted into bulk and added-value chemicals. Adipic acid (the precursor for nylon) is produced via a biochemical process from the carbohydrate fractions of the raw materials. Aromatic chemicals are produced from the lignin fraction of GROT. Furthermore, the micro-algae will be assessed as a source of added-value chemicals.
The environmental impact of this process system is assessed based on lab-scale and literature data and information, and the influence on the environmental performance of scaling up the concept is quantified. This is done by applying process modelling and simulation using the lab-scale data. These data and process simulation are also used for the assessment of the potential integration of the process system into existing industry and the economic advantage thereof.
The assessments are carried out during the technology development and inform the technology developers and researchers where to focus their efforts to improve the biorefinery concept and make it sustainable.
