Research context and mission

Nutrients play a pivotal role in sustaining global food security, relying on the biological upgrading of simple inorganic fertilizer molecules such as ammonium to precious nutritional compounds such as essential amino acids. The inefficiencies and losses along the food production chain and upon consumption however yield unacceptable environmental changes. This profiling of mainly nitrogen and phosphorus as double-edged swords is additionally entangled to (fossil) energy and (fresh) water demand. By 2050, the tension on this nexus will strongly increase, with figures of 30, 40 and 50% for water, energy, and food respectively.

The research team of prof. dr. ir. Siegfried E. Vlaeminck endeavors to alleviate tensions in the nutrient-energy-water nexus through a dedicated focus on novel resource-efficient nutrient management biotechnology, bearing in mind the boundaries of local socio-economic situations. The particular core expertise lies in the design of bioreactors and process configurations, along with the development of dedicated microbiome steering tools. In the philosophy of sustainability, maximum efficiency of resources (e.g. energy and chemicals) and minimum emissions of harmful compounds (e.g. N2O) are the guiding compasses. This renders a niche for removal, recovery and production technologies. For the latter two, dedicated attention is oriented toward the market demand side, meeting requirements in terms of quantity and quality of end-users.

Prof. Vlaeminck’s bioconversion interests encompass biological nutrient recovery (micro-algae, photoheterotrophs, single cell protein,…), short-cut nitrogen removal (partial nitritation/anammox and nitritation/denitritation), biological phosphorus removal, conventional biological nitrogen removal, reuse of recovered products,... The influent scope ranges from domestic over industrial to agricultural or aquacultural streams, be it in end-of-pipe collection systems or in source separation schemes (e.g. black, brown, grey, yellow water). Besides the terrestrial context, a dedicated focus is oriented toward biological life support systems for Space. The group’s methodology spans from lab- to full-scale reactors and from microbial analyses to process control and microbiome management.

By doing so, prof. Vlaeminck and his team aim to ambitiously contribute in rendering global food production more sustainable at the level of the environment, the economy and the society at large.
