Knowledge pushed strategies to spice up microalgae manufacturing and CO2 seize



VTT Technical Analysis Centre of Finland is coordinating a two-year analysis venture involving the College of Jyväskylä, Neste and 7 Finnish SMEs, collectively addressing a number of the bottlenecks in large-scale algal cultivation, because the group explains right here.

Microalgae are a promising feedstock for a lot of merchandise akin to gas, meals and supplies. On the identical time, algae are capable of repair massive quantities of CO2 that they use for development. Roughly 50% of the algae biomass is carbon, and as such, microalgae maintain nice potential to assist efforts to deal with local weather change. Nonetheless, large-scale algae farming faces technical challenges that hinder widespread economically profitable functions.

Undertaking ROBA – Strong Algae Methods, funded by Enterprise Finland, goals to deal with hurdles to create economically possible algae processes by way of a mixture of modelling, superior measurement expertise, bioprocess engineering, machine studying and artificial biology.

“Microalgae are one of many potential renewable and scalable future uncooked supplies that Neste is growing, with the intention to develop our renewable uncooked materials pool to assist future development of renewables manufacturing. We’re additionally in search of all potential options to scale back emissions with the intention to meet our bold purpose of carbon impartial manufacturing by 2035. Actions within the ROBA venture will contribute to those targets by specializing in an idea for refinery CO2 seize with microalgae and by growing monitoring strategies that may very well be utilized in large-scale algae cultivation,” explains Jason Michael Blake, Vice President of Innovation, Enterprise Platform Aviation Feedstock, at Neste.

One bottleneck in algae cultivations to be addressed is monitoring of contamination, which at present is a problem in large-scale processes and may result in lack of total cultures. In ROBA, a sequence of optical and different on-line strategies might be explored. The measurement applied sciences to be developed within the venture might be relevant additionally for different biotechnological processes.

“Industrial biotechnology is turning into increasingly more an essential a part of sustainable industrial practices. Our intention is to develop intensification strategies for large-scale algal cultivation. Progressive measurement and monitoring applied sciences will assist us to maneuver in the direction of environment friendly and economically possible manufacturing processes,” says Mervi Toivari, Principal Scientist at VTT.

Machine studying guarantees to take course of monitoring even one step additional, by combining numerous data acquired from the method right into a extra full image.

“It is a new opening to develop a novel on-site observer and computational strategies for the wants of microalgae biotechnology. The Spectral Imaging Laboratory on the College of Jyväskylä focuses on growing a non-invasive monitoring methodology primarily based on hyperspectral imager expertise. Monitoring the expansion and product accumulation of microalgae and detecting contamination are the important thing areas for the event,” says Pauliina Salmi, Postdoctoral Researcher from College of Jyväskylä.
