The Aachen-Maastricht Institute for Biobased Materials invites applications for a PhD-position in the sustainability assessment of carbon-negative biofuels from organic waste. The Ph.D. work will be performed within the framework of the EU Horizon Europe project CARBIOW.

Job description

Project information

The EU Horizon Europe Carbon Negative Biofuels from Organic Waste (CARBIOW) project addresses the green transition and circular economy by proposing novel technologies that cover the whole process of conversion of organic waste to biofuels. On one hand, hard-to-utilize organic waste such as the organic fraction of municipal solid waste and residues from biorefinery and biological processes are utilized to highlight a new bioenergy source. On the other hand, new technologies will be developed from TRL 2 to 5.

The proposed technologies via CARBIOW enable Europe to take the lead and advance in several fields of energy generation and energy sector decarbonization. Moreover, energy security, economical boost, local energy independence, and job creation are addressed. Torrefaction as an emerging technology converts the very heterogeneous and wet organic waste to a high-quality solid biofuel. Besides, torgas will be combusted with oxygen to generate energy for torrefaction, and to obtain nearly pure CO2. A novel technology i.e., oxygen-blown gasification in oxygen carrier aided systems will convert the torrefied organic waste to clean syngas with very high efficiency in terms of energy and yield. The syngas will be used in the Fischer-Tropsch process with a novel reactor and novel 3D printed catalysts aiming to produce aviation (kerosene) and marine (alcohols) biofuels. The CO2 from the oxy-conversion steps will be fixed in the resulting ashes from the same process via carbonization to make a cement-based product. So, CARBIOW addresses another goal which is the decarbonization of the cement industry, while making the biofuels to be carbon negative. The diversity and strength of the experts within the consortium of CARBIOW will guarantee the technological, technical, and societal advancement of what is proposed, most importantly, the exploitation and perspective of the whole process will be evaluated by the leaders and industrial sites to pledge the feasibility of the scale-up and further development of the proposed process.
