Op vrijdag 15 juni geeft prof. dr. ir. Ramon Ganigué zijn inaugurele les:

Anaerobic microbial technologies for waste valorization

Korte inhoud

Our society is transitioning from a linear "take, make, use, dispose" consumerism model to a circular economy in which wastes shall serve as raw materials for the production of commodities. This paradigm shift, triggered by a political and societal will, needs to be supported by new waste management schemes and novel technologies for waste valorization. Microbes can feed on a wide array of substrates and thrive in the most adverse environments. We, humans, have learned to harness them for the production of tasty cheese or vital antibiotics. At the onset of the twenty-first century, microbes can be instrumental in upcycling carbon-based waste into commodities.
Short- and medium-chain carboxylic acids are high-volume, high-value molecules with ample use as chemical building blocks. They can be produced from solid, liquid and gaseous waste and side-streams through fermentations. While bioproduction of target carboxylic acids from wastes is an attractive and promising route, it faces a number of shortcomings and bottlenecks, including unselective conversion, low production rates, high alkali dosing requirements and/or challenging (and often cost prohibitive) downstream processing.
In this lecture I will discuss the role of anaerobic microbial technologies as central cogs for urban bio-refining in the sustainable cities of the future. Taking the main urban waste streams as a starting point, I will outline the different routes by which these can be transformed into valuable bio-chemicals. Last but not least, I will put forward the key technological challenges ahead and discuss how my research activities will tackle them, with the ultimate goal of attaining sustainable and cost-effective bioproduction from wastes.
