BioSC Spotlight

The BioSC event series „Spotlight“ was initiated in the beginning of 2017. In each Spotlight, a selected topic relevant to bioeconomy is being discussed by BioSC scientists and external experts during a one-day event.

3rd BioSC Spotlight:

Phosphorus recovery and cycling for an independent and sustainable bioeconomy

Phosphor is an essential plant nutrient, but reserves of this finite resource occur outside Europe, creating a strong dependency to the value market and directly influencing farmers’ yields. Additionally, considerable amounts of applied phosphate leach into water or accumulate in the soil as fixed inorganic P forms or as for plant and animals indigestible form (phytate), leading to significant impact on the environment. Especially the re-use of Phosphorus for fertilizing is of great importance due its unequal and limited global distribution, the entry of heavy metals into food chains by mineral P fertilization, and the necessary removal of Phosphor from waste streams, e.g. by waste water treatment regulations. This Phosphor stewardship is of prime importance for an integrated bioeconomy to ensure a sufficient food production of a growing world population.

Different approaches towards Phosphor recovery and recycling have been investigated lately (e.g. transferring Phosphor from waste streams to crops by microalgae or isolating phosphate from the plant storage compound phytate through enzymatic hydrolysis). In the frame of the 3rd BioSC Spotlight event, current developments will be presented by scientists as well as stakeholders from industry and possible future directions will be discussed.

Participation is free of charge. Places are limited.
